<!--rehype:className=wrap-text -->
|
||||
<!--rehype:className=style-timeline-->
|
||||
|

### 创建项目
|
||||
<!--rehype:wrap-class=row-span-3-->
|
||||
|
||||
```bash
|
||||
$ django-admin startproject myworld
|
||||
```
|
||||
|
||||
创建了一个 `myworld` 文件夹,内容如下:
|
||||
|
||||
```bash
|
||||
myworld
|
||||
├┈ manage.py
|
||||
╰┈ myworld/
|
||||
├┈ __init__.py
|
||||
├┈ asgi.py
|
||||
├┈ settings.py
|
||||
├┈ urls.py
|
||||
╰┈ wsgi.py
|
||||
```
|
||||
|
||||
运行 Django 项目
|
||||
|
||||
```bash
|
||||
$ py manage.py runserver # Windows
|
||||
$ python manage.py runserver # Unix/MacOS
|
||||
```
|
||||
|
||||
打开一个新的浏览器窗口并在地址栏中输入 127.0.0.1:8000
|
||||
|
||||
### 检查 Django 版本
|
||||
|
||||
```bash
|
||||
(myproject) C:\Users\Your Name>django-admin --version
|
||||
# 4.0.3
|
||||
```
|
||||
|
||||
### 创建应用
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```bash
|
||||
$ py manage.py startapp members
|
||||
```
|
||||
|
||||
项目中创建了一个名为 `members` 的文件夹,内容如下:
|
||||
|
||||
```bash
|
||||
myworld
|
||||
├┈ manage.py
|
||||
├┈ myworld/
|
||||
╰┈ members/
|
||||
├┈ migrations/
|
||||
┆ ╰┈ __init__.py
|
||||
├┈ __init__.py
|
||||
├┈ admin.py
|
||||
├┈ apps.py
|
||||
├┈ models.py
|
||||
├┈ tests.py
|
||||
╰┈ views.py
|
||||
```
|
||||
|
||||
首先,看一下名为 `views.py` 的文件。这是我们收集发送回正确响应所需的信息的地方。
|
||||
|
||||
### 应用目录介绍
|
||||
|
||||
- `Django` 接收 URL,检查 `urls.py` 文件,并调用与 URL 匹配的视图。
|
||||
- 位于 `views.py` 中的视图检查相关模型。
|
||||
- 模型是从 `models.py` 文件中导入的。
|
||||
- 然后视图将数据发送到模板文件夹中的指定模板。
|
||||
- 模板包含 `HTML` 和 `Django` 标记,并使用数据将完成的 `HTML` 内容返回给浏览器
|
||||
|
||||
### 视图
|
||||
|
||||
Django 视图是接受 `http` 请求并返回 `http` 响应的 `Python` 函数,就像 `HTML` 文档一样。
|
||||
|
||||
使用 `Django` 的网页充满了不同任务和任务的视图。
|
||||
|
||||
视图通常放在一个名为 `views.py` 的文件中,该文件位于应用程序的文件夹中。
|
||||
|
||||
您的 `members` 文件夹中有一个 `views.py`,如下所示:
|
||||
|
||||
```PY
|
||||
from django.shortcuts import render
|
||||
|
||||
# Create your views here.
|
||||
```
|
||||
|
||||
找到它并打开它,并将内容替换为:
|
||||
|
||||
```PY
|
||||
from django.shortcuts import render
|
||||
from django.http import HttpResponse
|
||||
|
||||
def index(request):
|
||||
return HttpResponse("Hello world!")
|
||||
```
|
||||
|
||||
这是一个关于如何将响应发送回浏览器的简单示例。
|
||||
|
||||
但是我们如何执行视图呢? 好吧,我们必须通过 URL 调用视图。
|
||||
|
||||
### URLs
|
||||
|
||||
在与 `views.py` 文件相同的文件夹中创建一个名为 `urls.py` 的文件,并在其中输入以下代码:
|
||||
|
||||
```py
|
||||
from django.urls import path
|
||||
from . import views
|
||||
urlpatterns = [
|
||||
path('', views.index, name='index'),
|
||||
]
|
||||
```
|
||||
|
||||
刚刚创建的 `urls.py` 文件是特定于成员应用程序的。我们还必须在根目录 `myworld` 中进行一些路由。
|
||||
|
||||
在 `myworld` 文件夹中有一个名为 `urls.py` 的文件,打开该文件并在 `import` 语句中添加 `include` 模块,并在列表中添加一个 `path()` 函数。文件将如下所示:
|
||||
|
||||
```py
|
||||
from django.contrib import admin
|
||||
from django.urls import include, path
|
||||
|
||||
urlpatterns = [
|
||||
path('members/', include('members.urls')),
|
||||
path('admin/', admin.site.urls),
|
||||
]
|
||||
```
|
||||
|
||||
如果服务器未运行,请导航到 `/myworld` 文件夹并在命令提示符下执行此命令:
|
||||
|
||||
```bash
|
||||
$ py manage.py runserver
|
||||
```
|
||||
|
||||
在浏览器窗口的地址栏中输入 `127.0.0.1:8000/members/`
|
||||
|
||||
### 模板
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
在 `members` 文件夹中创建一个 `templates` 文件夹,并创建一个名为 `myfirst.html` 的 `HTML` 文件。文件结构应该是这样的:
|
||||
|
||||
```bash
|
||||
myworld
|
||||
├┈ manage.py
|
||||
├┈ myworld/
|
||||
╰┈ members/
|
||||
╰┈ templates/
|
||||
╰┈ myfirst.html
|
||||
```
|
||||
|
||||
打开 `HTML` 文件并插入以下内容:
|
||||
|
||||
```html
|
||||
<!DOCTYPE html>
|
||||
<html>
|
||||
<body>
|
||||
<h1>Hello World!</h1>
|
||||
<p>欢迎来到我的第一个 Django 项目!</p>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
修改视图 `members/views.py`
|
||||
|
||||
```py
|
||||
from django.http import HttpResponse
|
||||
from django.template import loader
|
||||
|
||||
def index(request):
|
||||
template = loader.get_template('myfirst.html')
|
||||
return HttpResponse(template.render())
|
||||
```
|
||||
|
||||
#### 更改设置
|
||||
|
||||
为了能够处理比“Hello World!”更复杂的东西,我们必须告诉 `Django` 一个新的应用程序已创建
|
||||
|
||||
这是在 `myworld` 文件夹的 `myworld/settings.py` 文件中完成的。查找 `INSTALLED_APPS[]` 列表并添加成员应用程序,如下所示:
|
||||
|
||||
```py
|
||||
INSTALLED_APPS = [
|
||||
'django.contrib.admin',
|
||||
'django.contrib.auth',
|
||||
'django.contrib.contenttypes',
|
||||
'django.contrib.sessions',
|
||||
'django.contrib.messages',
|
||||
'django.contrib.staticfiles',
|
||||
'members.apps.MembersConfig'
|
||||
]
|
||||
```
|
||||
|
||||
然后运行这个命令:
|
||||
|
||||
```bash
|
||||
$ py manage.py migrate
|
||||
```
|
||||
|
||||
通过导航到 `/myworld` 文件夹启动服务器并执行以下命令:
|
||||
|
||||
```bash
|
||||
$ py manage.py runserver
|
||||
```
|
||||
|
||||
在浏览器窗口的地址栏中输入 127.0.0.1:8000/members/
|
||||
|
||||
### 创建表(模型)
|
||||
<!--rehype:wrap-class=col-span-2-->
|
||||
|
||||
在 `/members/` 文件夹中,打开 `models.py` 文件。要在我们的数据库中添加成员表,首先创建一个成员类,并描述其中的表字段:
|
||||
|
||||
```py
|
||||
from django.db import models
|
||||
|
||||
class Members(models.Model):
|
||||
firstname = models.CharField(max_length=255)
|
||||
lastname = models.CharField(max_length=255)
|
||||
```
|
||||
|
||||
然后导航到 `/myworld/` 文件夹并运行以下命令:
|
||||
|
||||
```bash
|
||||
$ py manage.py makemigrations members
|
||||
# Migrations for 'members':
|
||||
# members\migrations\0001_initial.py
|
||||
# - Create model Members
|
||||
```
|
||||
|
||||
创建一个包含任何新更改的文件并将该文件存储在 `/migrations/` 文件夹中。下次运行 `py manage.py migrate` 时,Django 将根据迁移文件夹中新文件的内容创建并执行一条 SQL 语句。运行迁移命令:
|
||||
|
||||
```bash
|
||||
$ py manage.py migrate
|
||||
```
|
||||
|
||||
从模型创建的 SQL 语句是:
|
||||
|
||||
```sql
|
||||
CREATE TABLE "members_members" (
|
||||
"id" INT NOT NULL PRIMARY KEY AUTOINCREMENT,
|
||||
"firstname" varchar(255) NOT NULL,
|
||||
"lastname" varchar(255) NOT NULL
|
||||
);
|
||||
```
|
||||
|
||||

context = {
|
||||
'firstname': '狂徒张三',
|
||||
}
|
||||
return HttpResponse(template.render(context, request))
|

|
||||
|
||||
### cycle
|
||||
<!--rehype:wrap-class=col-span-2 row-span-3-->

如果你想为每次循环使用新的背景颜色,你可以使用 `cycle` 标签来做到这一点
|
||||
|
||||
```django
|
||||
<ul>
|
||||
{% for x in members %}
|
||||
<li style='background-color:{% cycle 'lightblue' 'pink' 'yellow' 'coral' 'grey' %}'>
|
||||
{{ x.firstname }}
|
||||
</li>
|
||||
{% endfor %}
|
||||
</ul>
|
||||
```
|
||||
|
||||
将参数值保存在变量中,以便以后使用:
|
||||
|
||||
```django
|
||||
<ul>
|
||||
{% for x in members %}
|
||||
{% cycle 'lightblue' 'pink' 'yellow' 'coral' 'grey' as bgcolor silent %}
|
||||
<li style='background-color:{{ bgcolor }}'>
|
||||
{{ x.firstname }}
|
||||
</li>
|
||||
{% endfor %}
|
||||
</ul>
|
||||
```
|
||||
|
||||
你注意到 `silent` 关键字了吗? 确保添加这个,否则参数值将在输出中显示两次
|
||||
|
||||
```django
|
||||
<ul>
|
||||
{% for x in members %}
|
||||
{% cycle 'lightblue' 'pink' 'yellow' 'coral' 'grey' as bgcolor silent %}
|
||||
{% if forloop.counter == 3 %}
|
||||
{% resetcycle %}
|
||||
{% endif %}
|
||||
<li style='background-color:{{ bgcolor }}'>
|
||||
{{ x.firstname }}
|
||||
</li>
|
||||
{% endfor %}
|
||||
</ul>
|
||||
```
|
||||
|
||||
您可以使用 `{% resetcycle %}` 标签强制循环重新开始
|
||||
|
||||
### 每一行添加行号
|
||||
|
||||
```django
|
||||
{% filter upper|linenumbers %}Hello!
|
||||
my name is
|
||||
Emil.
|
||||
What is your name?{% endfilter %}

```js {2,3}
|
||||
promise
|
||||
.then((result) => { ··· })
|
||||
.catch((error) => { ··· })
|
||||
```
|
||||
|
||||
### 在 finally 中使用 Promise
|
||||
|
||||
```js {4}
|
||||
promise
|
||||
.then((result) => { ··· })
|
||||
.catch((error) => { ··· })
|
||||
.finally(() => {
|
||||
/* 独立于成功/错误的逻辑 */
|
||||
})
|
||||
```
|
||||
|
||||
当承诺被履行或被拒绝时,处理程序被调用
|
||||
|
||||
### Promise 函数
|
||||
|
||||
```js
|
||||
Promise.all(···)
|
||||
Promise.race(···)
|
||||
Promise.reject(···)
|
||||
Promise.resolve(···)
|
||||
```
|
||||
|
||||
### Async-await
|
||||
|
||||
```js {2,3}
|
||||
async function run () {
|
||||
const user = await getUser()
|
||||
const tweets = await getTweets(user)
|
||||
return [user, tweets]
|
||||
}
|
||||
```
|
||||
|
||||
`async` 函数是使用函数的另一种方式。
|
||||
请参阅:[异步函数](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function)
|
||||
|
||||
解构 Destructuring
|
||||
-------------
|
||||
|
||||
### 解构赋值
|
||||
|
||||
#### Arrays
|
||||
|
||||
```js {1}
|
||||
const [first, last] = ['Nikola', 'Tesla']
|
||||
```
|
||||
|
||||
#### Objects
|
||||
|
||||
```js {1}
|
||||
let {title, author} = {
|
||||
title: 'The Silkworm',
|
||||
author: 'R. Galbraith'
|
||||
}
|
||||
```
|
||||
|
||||
支持匹配数组和对象。
|
||||
请参阅:[解构](https://babeljs.io/learn-es2015/#destructuring)
|
||||
|
||||
### 默认值
|
||||
|
||||
```js
|
||||
const scores = [22, 33]
|
||||
const [math = 50, sci = 50, arts = 50] = scores
|
||||
```
|
||||
----
|
||||
```js
|
||||
// Result:
|
||||
// math === 22, sci === 33, arts === 50
|
||||
```
|
||||
|
||||
可以在解构数组或对象时分配默认值
|
||||
|
||||
### 函数参数
|
||||
|
||||
```js {1}
|
||||
function greet({ name, greeting }) {
|
||||
console.log(`${greeting}, ${name}!`)
|
||||
}
|
||||
```
|
||||
----
|
||||
```js
|
||||
greet({ name: 'Larry', greeting: 'Ahoy' })
|
||||
```
|
||||
|
||||
对象和数组的解构也可以在函数参数中完成
|
||||
|
||||
### 默认值
|
||||
|
||||
```js {1}
|
||||
function greet({ name = 'Rauno' } = {}) {
|
||||
console.log(`Hi ${name}!`);
|
||||
}
|
||||
```
|
||||
----
|
||||
```js
|
||||
greet() // Hi Rauno!
|
||||
greet({ name: 'Larry' }) // Hi Larry!
|
||||
```
|
||||
|
||||
### 重新分配键
|
||||
|
||||
```js {1}
|
||||
function printCoordinates({ left: x, top: y }) {
|
||||
console.log(`x: ${x}, y: ${y}`)
|
||||
}
|
||||
```
|
||||
----
|
||||
```js
|
||||
printCoordinates({ left: 25, top: 90 })
|
||||
```
|
||||
|
||||
此示例将 `x` 分配给 `left` 键的值
|
||||
|
||||
### 循环
|
||||
|
||||
```js {1}
|
||||
for (let {title, artist} of songs) {
|
||||
···
|
||||
}
|
||||
```
|
||||
|
||||
赋值表达式也在循环中工作
|
||||
|
||||
### 对象解构
|
||||
|
||||
```js {1}
|
||||
const { id, ...detail } = song;
|
||||
```
|
||||
|
||||
使用 `rest(...)` 运算符单独提取一些键和对象中的剩余键
|
||||
|
||||
扩展运算符 Spread
|
||||
------
|
||||
|
||||
### 对象扩展
|
||||
|
||||
#### 与对象扩展
|
||||
|
||||
```js {2}
|
||||
const options = {
|
||||
...defaults,
|
||||
visible: true
|
||||
}
|
||||
```
|
||||
|
||||
#### 没有对象扩展
|
||||
|
||||
```js
|
||||
const options = Object.assign(
|
||||
{}, defaults,
|
||||
{ visible: true })
|
||||
```
|
||||
|
||||
对象扩展运算符允许您从其他对象构建新对象。
|
||||
请参阅:[对象传播](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator)
|
||||
|
||||
### 数组扩展
|
||||
|
||||
#### 具有数组扩展
|
||||
|
||||
```js {2,3}
|
||||
const users = [
|
||||
...admins,
|
||||
...editors,
|
||||
'rstacruz'
|
||||
]
|
||||
```
|
||||
|
||||
#### 没有数组扩展
|
||||
|
||||
```js
|
||||
const users = admins
|
||||
.concat(editors)
|
||||
.concat([ 'rstacruz' ])
|
||||
```
|
||||
|
||||
扩展运算符允许您以相同的方式构建新数组。
|
||||
请参阅:[扩展运算符](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator)
|
||||
|
||||

return x * y.length
|
||||
}
|
||||
```
|

|
||||
#### 扩展
|
||||
|
||||
```js {1}
|
||||
fn(...[1, 2, 3])
|
||||
// 与 fn(1, 2, 3) 相同
|
||||
```
|

||||
readFile('text.txt', (err, data) => {
|
||||
...
|
||||
})
|
||||
```
|
||||
|
||||
#### 隐式返回
|
||||
|
||||
```js {1,4,5,6}
|
||||
arr.map(n => n*2)
|
||||
// 没有花括号 = 隐式返回
|
||||
// 同: arr.map(function (n) { return n*2 })
|
||||
arr.map(n => ({
|
||||
result: n*2
|
||||
}))
|
||||
// 隐式返回对象需要在对象周围加上括号
|
||||
```
|
||||
|
||||
类似函数,但保留了 `this`。
|
||||
请参阅:[箭头函数](https://babeljs.io/learn-es2015/#arrows-and-lexical-this)
|
||||
|
||||
### 参数设置默认值

||||
|
||||
```js
|
||||
function log(x, y = 'World') {
|
||||
console.log(x, y);
|
||||
}
|
||||
|

log('Hello') // Hello World
|
||||
log('Hello', 'China') // Hello China
|
||||
log('Hello', '') // Hello
|
||||
```
|
||||
|

### 与解构赋值默认值结合使用
|
||||
|
||||
```js
|
||||
function foo({x, y = 5} = {}) {
|
||||
console.log(x, y);
|

// [57, "张三"]
|
||||
Object.entries(fatherJS)
|
||||
// [["age", 57], ["name", "张三"]]
|
||||
```
|
||||
|
||||
Modules 模块
|
||||
-------
|
||||
|
||||
### Imports 导入
|
||||
|
||||
```js
|
||||
import 'helpers'
|
||||
// 又名: require('···')
|
||||
```
|
||||
---
|
||||
```js
|
||||
import Express from 'express'
|
||||
// 又名: const Express = require('···').default || require('···')
|
||||
```
|
||||
---
|
||||
```js
|
||||
import { indent } from 'helpers'
|
||||
// 又名: const indent = require('···').indent
|
||||
```
|
||||
---
|
||||
```js
|
||||
import * as Helpers from 'helpers'
|
||||
// 又名: const Helpers = require('···')
|
||||
```
|
||||
---
|
||||
```js
|
||||
import { indentSpaces as indent } from 'helpers'
|
||||
// 又名: const indent = require('···').indentSpaces
|
||||
```
|
||||
|
||||
`import` 是新的 `require()`。
|
||||
请参阅:[Module imports](https://babeljs.io/learn-es2015/#modules)
|
||||
|
||||
### Exports 导出
|
||||
|
||||
```js
|
||||
export default function () { ··· }
|
||||
// 又名: module.exports.default = ···
|
||||
```
|
||||
----
|
||||
```js
|
||||
export function mymethod () { ··· }
|
||||
// 又名: module.exports.mymethod = ···
|
||||
```
|
||||
----
|
||||
```js
|
||||
export const pi = 3.14159
|
||||
// 又名: module.exports.pi = ···
|
||||
```
|
||||
|
||||
----
|
||||
|
||||
```js
|
||||
const firstName = 'Michael';
|
||||
const lastName = 'Jackson';
|
||||
const year = 1958;
|
||||
export { firstName, lastName, year };
|
||||
```
|
||||
|
||||
----
|
||||
|
||||
```js
|
||||
export * from "lib/math";
|
||||
```
|
||||
|
||||
`export` 是新的`module.exports`。
|
||||
请参阅:[Module exports](https://babeljs.io/learn-es2015/#modules)
|
||||
|
||||
### `as` 关键字重命名
|
||||
|
||||
```js {2,8,12-14}
|
||||
import {
|
||||
lastName as surname // 导入重命名
|
||||
} from './profile.js';
|
||||
|
||||
function v1() { ... }
|
||||
function v2() { ... }
|
||||
|
||||
export { v1 as default };
|
||||
// 等同于 export default v1;
|
||||
|
||||
export {
|
||||
v1 as streamV1, // 导出重命名
|
||||
v2 as streamV2, // 导出重命名
|
||||
v2 as streamLatestVersion // 导出重命名
|
||||
};
|
||||
```
|
||||
|
||||
### 动态加载模块
|
||||
|
||||
```js
|
||||
button.addEventListener('click', event => {
|
||||
import('./dialogBox.js')
|
||||
.then(dialogBox => {
|
||||
dialogBox.open();
|
||||
})
|
||||
.catch(error => {
|
||||
/* Error handling */
|
||||
})
|
||||
});
|
||||
```
|
||||
|
||||
[ES2020提案](https://github.com/tc39/proposal-dynamic-import) 引入 `import()` 函数
|
||||
|
||||
### import() 允许模块路径动态生成
|
||||
|
||||
```js
|
||||
const main = document.querySelector('main')
|
||||
|
||||
import(`./modules/${someVariable}.js`)
|
||||
.then(module => {
|
||||
module.loadPageInto(main);
|
||||
})
|
||||
.catch(err => {
|
||||
main.textContent = err.message;
|
||||
});
|
||||
```
|
||||
|
||||
### import.meta
|
||||
|
||||
[ES2020](https://github.com/tc39/proposal-import-meta) 为 `import` 命令添加了一个元属性 `import.meta`,返回当前模块的元信息
|
||||
|
||||
```js
|
||||
new URL('data.txt', import.meta.url)
|
||||
```
|
||||
|
||||
Node.js 环境中,`import.meta.url`返回的总是本地路径,即 `file:URL` 协议的字符串,比如 `file:///home/user/foo.js`
|
||||
|
||||
|
||||
Generators
|
||||
----------
|
||||
|
||||
### Generator 函数
|
||||
|
||||
```js
|
||||
function* idMaker () {
|
||||
let id = 0
|
||||
while (true) { yield id++ }
|
||||
}
|
||||
```
|
||||
---
|
||||
```js
|
||||
let gen = idMaker()
|
||||
gen.next().value // → 0
|
||||
gen.next().value // → 1
|
||||
gen.next().value // → 2
|
||||
```
|
||||
|
||||
情况很复杂。
|
||||
请参阅:[Generators](https://babeljs.io/learn-es2015/#generators)
|
||||
|
||||
### For..of + 迭代器(iterator)
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```js
|
||||
let fibonacci = {
|
||||
[Symbol.iterator]() {
|
||||
let pre = 0, cur = 1;
|
||||
return {
|
||||
next() {
|
||||
[pre, cur] = [cur, pre + cur];
|
||||
return { done: false, value: cur }
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
for (var n of fibonacci) {
|
||||
// 在 1000 处截断序列
|
||||
if (n > 1000) break;
|
||||
console.log(n);
|
||||
}
|
||||
```
|
||||
|
||||
用于迭代生成器和数组。
|
||||
请参阅:[For..of iteration](https://babeljs.io/learn-es2015/#iterators--forof)
|
||||
|
||||
### 与 Iterator 接口的关系
|
||||
|
||||
```js
|
||||
var gen = {};
|
||||
gen[Symbol.iterator] = function* () {
|
||||
yield 1;
|
||||
yield 2;
|
||||
yield 3;
|
||||
};
|
||||
|
||||
[...gen] // => [1, 2, 3]
|
||||
```
|
||||
|
||||
`Generator` 函数赋值给 `Symbol.iterator` 属性,从而使得 `gen` 对象具有了 `Iterator` 接口,可以被 `...` 运算符遍历了
|
||||
|
||||
|
||||
### Symbol.iterator 属性
|
||||
|
||||
```js
|
||||
function* gen() { /* some code */ }
|
||||
var g = gen();
|
||||
|
||||
g[Symbol.iterator]() === g // true
|
||||
```
|
||||
|
||||
`gen` 是一个 `Generator` 函数,调用它会生成一个遍历器对象`g`。它的 `Symbol.iterator` 属性,也是一个遍历器对象生成函数,执行后返回它自己

### 裁剪
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i <input> -filter:v "crop=640:480:100:25" <output>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
通过从输入视频中复制偏移 `x=100px` `y=25px` 的相应窗口来创建 `640x480` 大小的输出视频
|
||||
|
||||
```bash
|
||||
# 裁剪到宽度 360,高度 640
|
||||
$ ffmpeg -i input.mov -filter:v 'crop=360:640:0:0' -codec:a copy output.mov
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
裁剪到宽度 360,高度 640,从坐标 (10, 20) 开始
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i input.mov -filter:v 'crop=360:640:10:20' -codec:a copy output.mov
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 缩放
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i <输入> -vf scale=640:480 <输出>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 视频帧速率
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i input.avi -r 24 output.avi
|
||||
```
|
||||
|
||||
将输出文件的帧速率强制为 24 fps
|
||||
|
||||
```bash
|
||||
$ ffmpeg -r 1 -i input.m2v -r 24 output.avi
|
||||
```
|
||||
|
||||
将输入文件的帧速率(仅对原始格式有效)强制为 1 fps,将输出文件的帧速率强制为 24 fps
|
||||
|
||||
### 剪切视频部分
|
||||
<!--rehype:wrap-class=col-span-2-->
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i <input> -ss 00:01:45 -t 00:02:35 -vcodec copy -acodec copy <output>
|
||||
$ ffmpeg -ss 00:00:30 -i orginalfile.mpg -t 00:00:05 -vcodec copy -acodec copy newfile.mpg
|
||||
# 从 4.5 秒开始的 5 秒长的视频
|
||||
$ ffmpeg -i in.mp4 -ss 4.5 -t 5 out.mp4
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### H265 2-pass 编码
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```bash
|
||||
$ ffmpeg -y -i <input> -c:v libx265 -b:v 2600k \
|
||||
-x265-params pass=1 \
|
||||
-an -f mp4 /dev/null && \
|
||||
ffmpeg -i <input> \
|
||||
-c:v libx265 -b:v 2600k \
|
||||
-x265-params pass=2 \
|
||||
-c:a aac -b:a 128k output.mp4
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
对于 `H265 2-pass` 编码,您需要组合 `2` 个 `ffmpeg` 调用
|
||||
|
||||
### 视频比特率设置
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i input.avi -b:v 64k -bufsize 64k output.avi
|
||||
```
|
||||
|
||||
将输出文件的视频比特率设置为 64 kbit/s
|
||||
|
||||
### 固定旋转
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i <input> -c copy -metadata:s:v:0 rotate=90 <output>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
不要为旋转重新编码,而是简单地为旋转角度添加一个视频元数据字段
|
||||
|
||||
### 放慢视频速度
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i in.mp4 -filter:v "setpts=4.0*PTS" out.mp4
|
||||
```
|
||||
|
||||
使用过滤器减慢视频。 此示例将视频减慢四倍
|
||||
|
||||
### 缩放到特定宽度
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i in.mp4 -filter:v scale="538:trunc(ow/a/2)*2" -c:a copy out.mp4
|
||||
```
|
||||
|
||||
给定所需的视频宽度,例如 538 像素,您可以使用以下方法将视频调整为该宽度,同时保持宽高比
|
||||
|
||||
重新包装

|
||||
|
||||
### 提取音频流
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i file.mp4 -vn -acodec copy output.aac
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
将`-vn`(无视频)与 `-acodec copy` 结合起来。请注意,输出文件扩展名必须与输入文件中的音频编解码器匹配,`-acodec copy` 才能工作。
|
||||
|
||||
### 创建缩略图
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
在 10 秒时创建一个缩略图
|
||||
|
||||
```bash
|
||||
$ ffmpeg -ss 10 -i <input file> -vframes 1 -vcodec png -an thumb.png
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
例如,要每 `n` 秒创建一次缩略图,请使用 `-vf fps=1/n`
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i <input file> -vf fps=1/60 thumbnails/thumb%03d.png
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||

|
||||
|
||||
设置
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i file.mp3 -acodec copy -metadata title="<title>" -metadata artist="<artist>" -metadata album="<album>" out.mp3
|
||||
```

||||
|
||||
```bash
|
||||
$ ffmpeg -i file.aac -acodec mp3 -ar 44100 -ab 128000 output.mp3
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||

|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
将容器从 `MKV` 更改为 `MP4`
|
||||

```bash
|
||||
$ ffmpeg -i file.mkv -acodec copy -vcodec copy file.mp4
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
要将视频从 `.mov` 更改为 `.mp4`

||||
```bash
|
||||
$ ffmpeg -i in.mov out.mp4
|
||||
```

```bash
|
||||
$ git update-ref -d HEAD
|
||||
```
|
||||
|
||||
把所有的改动都重新放回工作区,并**清空所有的 commit**,这样就可以重新提交第一个 `commit` 了
|

|
||||
# 查看代理
|
||||
$ git config --global http.proxy
|
||||
$ git config --global https.proxy
|
||||
$ git config --global socks.proxy
|
||||
|
||||
# 设置代理
|
||||
# 适用于 privoxy 将 socks 协议转为 http 协议的 http 端口
|
||||
$ git config --global http.proxy http://127.0.0.1:1080
|
||||
$ git config --global https.proxy http://127.0.0.1:1080
|
||||
$ git config --global socks.proxy 127.0.0.1:1080
|
||||
|
||||
# 取消代理
|
||||
$ git config --global --unset http.proxy
|
||||
$ git config --global --unset https.proxy
|
||||
$ git config --global --unset socks.proxy
|
||||
|
||||
# 只对 github.com 设置代理
|
||||
$ git config --global http.https://github.com.proxy socks5://127.0.0.1:1080
|
||||
$ git config --global https.https://github.com.proxy socks5://127.0.0.1:1080
|
||||
|
||||
# 取消 github.com 代理
|
||||
$ git config --global --unset http.https://github.com.proxy
|
||||
$ git config --global --unset https.https://github.com.proxy
|
||||
```
|
||||
|
||||
|
||||
### clone 最新一次提交
|
||||
|
||||
```bash
|
||||
$ git clone --depth=1 https://github.com/user/repo.git
|
||||
```
|
||||
|
||||
只会 `clone` 最近一次提交,将减少 `clone` 时间
|
||||
|
||||
### 忽略某个文件的改动
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
关闭 track 指定文件的改动,也就是 Git 将不会在记录这个文件的改动
|
||||
|
||||
```bash
|
||||
git update-index --assume-unchanged path/to/file
|
||||
```
|
||||
<!--rehype:className=wrap-text-->
|
||||
|
||||
恢复 track 指定文件的改动
|
||||
|
||||
```bash
|
||||
git update-index --no-assume-unchanged path/to/file
|
||||
```
|
||||
<!--rehype:className=wrap-text-->
|
||||
|
||||
### 以最后提交的顺序列出所有 Git 分支
|
||||
|
||||
```bash
|
||||
git for-each-ref --sort=-committerdate --format='%(refname:short)' refs/heads
|
||||
```
|
||||
|
||||
最新的放在最上面
|
||||
|
||||
### 在 commit log 中查找相关内容
|
||||
|
||||
```bash
|
||||
git log --all --grep='<given-text>'
|
||||
```
|
||||
|
||||
通过 grep 查找,given-text: 所需要查找的字段
|
||||
|
||||
### 把暂存区的指定 file 放到工作区中
|
||||
|
||||
```bash
|
||||
git reset <file-name>
|
||||
```
|
||||
|
||||
不添加参数,默认是 `-mixed`
|
||||
|
||||
### 配置 SSH 协议代理
|
||||
|
||||
```shell
|
||||
# 对于使用 git@ 协议的,可以配置 socks5 代理
|
||||
# macOS 系统编辑 ~/.ssh/config 文件,添加这几行,设置 github 代理
|
||||
Host github.com
|
||||
ProxyCommand nc -X 5 -x 127.0.0.1:1080 %h %p
|
||||
```

||||
String s1 = new String("QuickRef");
|
||||
String s2 = new String("QuickRef");
|
||||
s1 == s2 // false
|
||||
s1.equals(s2) // true
|
||||
"AB".equalsIgnoreCase("ab") // true
|
||||
```
|
||||
|
||||
### 操纵
|
||||
|
||||
```java
|
||||
String str = "Abcd";
|
||||
str.toUpperCase(); // ABCD
|
||||
str.toLowerCase(); // abcd
|
||||
str.concat("#"); // Abcd#
|
||||
str.replace("b", "-"); // A-cd
|
||||
" abc ".trim(); // abc
|
||||
"ab".toCharArray(); // {'a', 'b'}
|
||||
```
|
||||
|
||||
### 信息
|
||||
|
||||
```java
|
||||
String str = "abcd";
|
||||
str.charAt(2); // c
|
||||
str.indexOf("a") // 0
|
||||
str.indexOf("z") // -1
|
||||
str.length(); // 4
|
||||
str.toString(); // abcd
|
||||
str.substring(2); // cd
|
||||
str.substring(2,3); // c
|
||||
str.contains("c"); // true
|
||||
str.endsWith("d"); // true
|
||||
str.startsWith("a"); // true
|
||||
str.isEmpty(); // false
|
||||
```
|
||||
|
||||
### 不可变
|
||||
|
||||
```java
|
||||
String str = "hello";
|
||||
str.concat("world");
|
||||
// 输出: hello
|
||||
System.out.println(str);
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
```java
|
||||
String str = "hello";
|
||||
String concat = str.concat("world");
|
||||
// 输出: helloworld
|
||||
System.out.println(concat);
|
||||
```
|
||||
|
||||
一旦创建就不能修改,任何修改都会创建一个新的String

int count = 0;
|
||||
while (count < 5) {
|
||||
System.out.print(count);
|
||||
count++;
|
||||
}
|
||||
// 输出: 01234
|
||||
```
|
||||
|
||||
### Do While 循环
|
||||
|
||||
```java
|
||||
int count = 0;
|
||||
do {
|
||||
System.out.print(count);
|
||||
count++;
|
||||
} while (count < 5);
|
||||
// 输出: 01234
|
||||
```
|
||||
|
||||
### 继续声明
|
||||
|
||||
```java
|
||||
for (int i = 0; i < 5; i++) {
|
||||
if (i == 3) {
|
||||
continue;
|
||||
}
|
||||
System.out.print(i);
|
||||
}
|
||||
// 输出: 01245
|
||||
```
|
||||
|
||||
### 中断语句
|
||||

|
||||
CREATE TABLE t(
|
||||
c1 INT, c2 INT, c3 VARCHAR,
|
||||
PRIMARY KEY (c1,c2)
|
||||
);
|
||||
```
|
||||
|
||||
将c2列设置为外键
|
||||
|
||||
```sql
|
||||
CREATE TABLE t1(
|
||||
c1 INT PRIMARY KEY,
|
||||
c2 INT,
|
||||
FOREIGN KEY (c2) REFERENCES t2(c2)
|
||||
);
|
||||
```
|
||||
|
||||
使c1和c2中的值唯一
|
||||
|
||||
```sql
|
||||
CREATE TABLE t(
|
||||
c1 INT, c1 INT,
|
||||
UNIQUE(c2,c3)
|
||||
);
|
||||
```
|
||||
|
||||
确保c1>0和c1>=c2中的值
|
||||
|
||||
```sql
|
||||
CREATE TABLE t(
|
||||
c1 INT, c2 INT,
|
||||
CHECK(c1> 0 AND c1 >= c2)
|
||||
);
|
||||
```
|
||||
c2列中的设置值不为NULL
|
||||
|
||||
```sql
|
||||
CREATE TABLE t(
|
||||
c1 INT PRIMARY KEY,
|
||||
c2 VARCHAR NOT NULL
|
||||
);
|
||||
```
|

|
||||
```
|
||||
|
||||
将行从t2插入t1
|
||||
|
||||
```sql

Vue 3 备忘清单
|
||||
===
|
||||
|
||||
渐进式 JavaScript 框架 [Vue 3](https://cn.vuejs.org/) 备忘清单的快速参考列表,包含常用 API 和示例。
|
||||
|
||||
|
||||
入门
|
||||
---
|
||||
|
||||
### 介绍
|
||||
|
||||
Vue 是一套用于构建用户界面的渐进式框架
|
||||
|
||||
- [Vue 3.x 官方文档](https://cn.vuejs.org/)
|
||||
- [Vue Router 4.x 官方文档](https://router.vuejs.org/zh/)
|
||||
<!--rehype:className=style-round-->
|
||||
|
||||
注意:Vue 3.x 版本对应 Vue Router 4.x 路由版本
|
||||
|
||||
### 创建应用
|
||||
<!--rehype:wrap-class=row-span-3-->
|
||||
|
||||
已安装 `16.0` 或更高版本的 Node.js
|
||||
|
||||
```bash
|
||||
$ npm init vue@latest
|
||||
```
|
||||
|
||||
指令将会安装并执行 [create-vue](https://www.npmjs.com/package/create-vue),它是 Vue 官方的项目脚手架工具
|
||||
|
||||
```bash
|
||||
✔ Project name: … <your-project-name>
|
||||
✔ Add TypeScript? … No/Yes
|
||||
✔ Add JSX Support? … No/Yes
|
||||
✔ Add Vue Router for Single Page Application development? … No/Yes
|
||||
✔ Add Pinia for state management? … No/Yes
|
||||
✔ Add Vitest for Unit testing? … No/Yes
|
||||
✔ Add Cypress for both Unit and End-to-End testing? … No/Yes
|
||||
✔ Add ESLint for code quality? … No/Yes
|
||||
✔ Add Prettier for code formatting? … No/Yes
|
||||
|
||||
Scaffolding project in ./<your-project-name>...
|
||||
Done.
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
安装依赖并启动开发服务器
|
||||
|
||||
```bash
|
||||
$ cd <your-project-name>
|
||||
$ npm install
|
||||
$ npm run dev
|
||||
```
|
||||
|
||||
当你准备将应用发布到生产环境时,请运行:
|
||||
|
||||
```bash
|
||||
$ npm run build
|
||||
```
|
||||
|
||||
此命令会在 `./dist` 文件夹中为你的应用创建一个生产环境的构建版本
|
||||
|
||||
### 应用实例
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```js
|
||||
import { createApp } from 'vue'
|
||||
|
||||
const app = createApp({
|
||||
data() {
|
||||
return { count: 0 }
|
||||
}
|
||||
})
|
||||
app.mount('#app')
|
||||
```
|
||||
|
||||
挂载应用
|
||||
|
||||
```html
|
||||
<div id="app">
|
||||
<button @click="count++">
|
||||
{{ count }}
|
||||
</button>
|
||||
</div>
|
||||
```
|
||||
|
||||
### 通过 CDN 使用 Vue
|
||||
|
||||
```html
|
||||
<script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>
|
||||
<div id="app">{{ message }}</div>
|
||||
<script>
|
||||
const { createApp } = Vue
|
||||
createApp({
|
||||
data() {
|
||||
return {
|
||||
message: 'Hello Vue!'
|
||||
}
|
||||
}
|
||||
}).mount('#app')
|
||||
</script>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 使用 ES 模块构建版本
|
||||
|
||||
```html
|
||||
<div id="app">{{ message }}</div>
|
||||
<script type="module">
|
||||
import { createApp } from 'https://unpkg.com/vue@3/dist/vue.esm-browser.js'
|
||||
createApp({
|
||||
data() {
|
||||
return {
|
||||
message: 'Hello Vue!'
|
||||
}
|
||||
}
|
||||
}).mount('#app')
|
||||
</script>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
模板语法
|
||||
---
|
||||
|
||||
### 文本插值
|
||||
|
||||
```html
|
||||
<span>Message: {{ msg }}</span>
|
||||
```
|
||||
|
||||
使用的是 `Mustache` 语法 (即双大括号),每次 `msg` 属性更改时它也会同步更新
|
||||
|
||||
### 原始 HTML
|
||||
<!--rehype:wrap-class=col-span-2-->
|
||||
|
||||
```html
|
||||
<p>Using text interpolation: {{ rawHtml }}</p>
|
||||
<p>Using v-html directive: <span v-html="rawHtml"></span></p>
|
||||
```
|
||||
|
||||
双大括号`{{}}`会将数据解释为纯文本,使用 `v-html` 指令,将插入 HTML
|
||||
|
||||
### Attribute 绑定
|
||||
|
||||
```html
|
||||
<div v-bind:id="dynamicId"></div>
|
||||
```
|
||||
|
||||
简写
|
||||
|
||||
```html
|
||||
<div :id="dynamicId"></div>
|
||||
```
|
||||
|
||||
### 布尔型 Attribute
|
||||
|
||||
```html
|
||||
<button :disabled="isButtonDisabled">
|
||||
Button
|
||||
</button>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 动态绑定多个值
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```js
|
||||
data() {
|
||||
return {
|
||||
objectOfAttrs: {
|
||||
id: 'container',
|
||||
class: 'wrapper'
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
通过不带参数的 `v-bind`,你可以将它们绑定到单个元素上
|
||||
|
||||
```html
|
||||
<div v-bind="objectOfAttrs"></div>
|
||||
```
|
||||
|
||||
### 使用 JavaScript 表达式
|
||||
|
||||
```html
|
||||
{{ number + 1 }}
|
||||
{{ ok ? 'YES' : 'NO' }}
|
||||
{{ message.split('').reverse().join('') }}
|
||||
|
||||
<div :id="`list-${id}`"></div>
|
||||
```
|
||||
|
||||
### 仅支持表达式(例子都是无效)
|
||||
|
||||
```html
|
||||
<!-- 这是一个语句,而非表达式 -->
|
||||
{{ var a = 1 }}
|
||||
<!-- 条件控制也不支持,请使用三元表达式 -->
|
||||
{{ if (ok) { return message } }}
|
||||
```
|
||||
|
||||
### 调用函数
|
||||
|
||||
```html
|
||||
<span :title="toTitleDate(date)">
|
||||
{{ formatDate(date) }}
|
||||
</span>
|
||||
```
|
||||
|
||||
|
||||
### 指令 Directives
|
||||
|
||||
```html
|
||||
<p v-if="seen">Now you see me</p>
|
||||
```
|
||||
|
||||
### 参数 Arguments
|
||||
|
||||
```html
|
||||
<a v-bind:href="url"> ... </a>
|
||||
<!-- 简写 -->
|
||||
<a :href="url"> ... </a>
|
||||
```
|
||||
|
||||
### 绑定事件
|
||||
|
||||
```html
|
||||
<a v-on:click="doSomething"> ... </a>
|
||||
<!-- 简写 -->
|
||||
<a @click="doSomething"> ... </a>
|
||||
```
|
||||
|
||||
### 动态参数
|
||||
|
||||
```html
|
||||
<a v-bind:[attributeName]="url"> ... </a>
|
||||
<!-- 简写 -->
|
||||
<a :[attributeName]="url"> ... </a>
|
||||
```
|
||||
|
||||
这里的 `attributeName` 会作为一个 JS 表达式被动态执行
|
||||
|
||||
### 动态的事件名称
|
||||
|
||||
```html
|
||||
<a v-on:[eventName]="doSomething"> ... </a>
|
||||
<!-- 简写 -->
|
||||
<a @[eventName]="doSomething">
|
||||
```
|
||||
|
||||
### 修饰符 Modifiers
|
||||
|
||||
```html
|
||||
<form @submit.prevent="onSubmit">
|
||||
...
|
||||
</form>
|
||||
```
|
||||
|
||||
`.prevent` 修饰符会告知 `v-on` 指令对触发的事件调用 `event.preventDefault()`
|
||||
|
||||
### 指令语法
|
||||
|
||||
```bash
|
||||
v-on:submit.prevent="onSubmit"
|
||||
──┬─ ─┬──── ─┬───── ─┬──────
|
||||
┆ ┆ ┆ ╰─ Value 解释为JS表达式
|
||||
┆ ┆ ╰─ Modifiers 由前导点表示
|
||||
┆ ╰─ Argument 跟随冒号或速记符号
|
||||
╰─ Name 以 v- 开头使用速记时可以省略
|
||||
```

||||
|
||||
### Yarn 与 npm 命令比较
|
||||
<!--rehype:wrap-class=col-span-2-->
|
||||
|
||||
npm(v5) | yarn | 说明
|
||||
:- | :- | :-
|
||||
`npm install` | `yarn add`, `yarn`| 安装依赖
|
||||
`npm init` | `yarn init` | 创建 `package.json` 文件

||||
`npm install gulp --save` | `yarn add gulp` | 安装 `gulp` 包
|
||||
`npm install gulp --save-dev --save-exact` | `yarn add gulp --dev --exact`
|
||||
`npm install -g gulp` | `yarn global add gulp`
|
||||
`npm update` | `yarn upgrade`
|
||||
`npm cache clean` | `yarn cache clean` | 清理缓存目录
|
||||
`./node_modules/.bin/gulp` | `yarn run gulp`
|
||||
<!--rehype:className=show-header left-align-->
