使用 Composer 镜像加速有两种选项：

• 选项一：全局配置，这样所有项目都能惠及（推荐）；
• 选项二：单独项目配置；

选项一、全局配置（推荐）

$ composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

选项二、单独使用

如果仅限当前工程使用镜像，去掉 -g 即可，如下：

$ composer config repo.packagist composer https://mirrors.aliyun.com/composer/

取消镜像

composer config -g --unset repos.packagist
composer config --unset repos.packagist

      "Status must be in { \"complete\", \"cancelled\" }"

  "message": "Invalid OrgGID provided."
}

Http Status

• 200 OK - [*] The request has succeeded.
• 400 INVALID REQUEST - [POST/PUT/PATCH] This response means that server could not understand the request due to invalid syntax.
• 401 Unauthorized - [*] Although the HTTP standard specifies "unauthorized", semantically this response means "unauthenticated"
• 403 Forbidden - [*] The client does not have access rights to the content, i.e. they are unauthorized, so the server is rejecting to give a proper response.
• 404 NOT FOUND - [*] The server cannot find the requested resource.
• 405 Method Not Allowed - [*] The request method is known by the server but is not supported by the target resource.
• 406 Not Acceptable - [*] This response is sent when the web server, after performing server-driven content negotiation, doesn't find any content following the criteria given by the user agent.
• 409 Conflict - [POST/PUT/PATCH] This response is sent when a request conflicts with the current state of the server
• 422 Unprocessable entity - [POST/PUT/PATCH] The request was well-formed but was unable to be followed due to semantic errors.
• 429 Too Many Requests - [*] The user has sent too many requests in a given amount of time ("rate limiting").
• 500 INTERNAL SERVER ERROR - [*] The server has encountered a situation it doesn't know how to handle.

Representational state transfer （REST）或者 RESTful
特点：结构清晰、符合标准、易于理解、扩展方便
REST这个词，是Roy Thomas Fielding在他2000年的博士论文中提出的。

什么是RESTful架构：

1. 每一个URI代表一种资源；
2. 客户端和服务器之间，传递这种资源的某种表现层；
3. 客户端通过四个HTTP动词，对服务器端资源进行操作，实现"表现层状态转化"。

总结：

• URL定位资源，用HTTP动词（GET,PUT,POST,DELETE,HEAD,OPTIONS）描述操作。
• REST描述的是在网络中client和server的一种交互形式；
• REST本身不实用，实用的是如何设计 RESTful API（REST风格的网络接口）
• Server提供的RESTful API中，URL中只使用名词来指定资源，原则上不使用动词。
• “资源”是REST架构或者说整个网络处理的核心

问题

• 在使用 $.val() 对一个input进行赋值时，只会解决 onchange事件
• 在使用 v-on:change 对该事件进行绑定时，发现无法监听到 change 事件
• v-model使用的是 input 事件而不是 change 导致 v-model 无法正常工作

解决办法

v-model 可以解决， 只需要在 change 事件中 触发一下 input 事件就好了。

$('#expire-date').on('change', function () {
  this.dispatchEvent(new Event('input'))
})

Success Message

{
  "code":0,
  "data":any  // any type of result
}

Failed Message

{
  "code":1, // 1-9999  >1
  "message":"string",  // error message
  "detail":any  // any detail of error message
}

Http Status Code HTTP Status Code

20x success status

Usually only use 200.
I only used 200 for success.

30x Redirect

4xx Client Response, Usually caused by the client side.

• 400 for parameters error message
• 422 for error message in process

5xx Server Response, Usually caused by the server side.
