axios 封装（单独引入element UI js文件、css文件）-马育民老师

# 说明

本案例适合在 `.html` 文件中，引入 `element UI` 的js文件、css文件，如下：

```
<link href="css/element-ui.css" rel="stylesheet">
<script src="js/vue.min.js"></script>
<script src="js/element-ui.js"></script>
<script src="js/axios.min.js"></script>
```

### 封装代码

```
// 全局路径
const url_all = {
	'DEV': '/', // 开发
	// 'DEV': 'http://192.168.0.203:8082/airship', // 开发
	'PRD': '/airship', // 生产环境。不能是 ./ ，因为前端路径会跟着改变
}

export let BASEURL = url_all['DEV']

// vue对象，在下面要使用 element UI 窗口
let vueObject ;

// create an axios instance
const request = axios.create({
  baseURL: BASEURL, // url = base url + request url
  // withCredentials: true, // send cookies when cross-domain requests
  timeout: 5000 // request timeout
})

// request interceptor
//request.interceptors.request.use(
//  config => {
//    // do something before request is sent
//
//    if (store.getters.token) {
//      // let each request carry token
//      // ['X-Token'] is a custom headers key
//      // please modify it according to the actual situation
//      config.headers['X-Token'] = getToken()
//    }
//    return config
//  },
//  error => {
//    // do something with request error
//    console.log(error) // for debug
//    return Promise.reject(error)
//  }
//)

// response interceptor
request.interceptors.response.use(
  /**
   * If you want to get http information such as headers or status
   * Please return  response => response
  */

/**
   * Determine the request status by custom code
   * Here is just an example
   * You can also judge the status by HTTP Status Code
   */
  response => {
    const res = response.data
//    console.log("res:",res)
    // if the custom code is not 20000, it is judged as an error.
    if(res.code == 0){
        return res
    }else if(res.code == 100){
        location.href='/static/login.html'
    }else{
      vueObject.$message({
        message: res.msg || 'Error',
        type: 'error',
        duration: 5 * 1000
      })

return Promise.reject(new Error(res.msg || 'Error'))
    }
  },
  error => {
    console.log('err' + error) // for debug
    vueObject.$message({
      message: error.message,
      type: 'error',
      duration: 5 * 1000
    })
    return Promise.reject(error)
  }
)

/**
 * post 请求
 * 数据以json格式发送到服务器
 */
export const post =(vue,url,data)=>{
    vueObject = vue
	return request({
        url: url,
        method: 'post',
        data
      })
}

/**
 * get请求
 * 请求头 content-type 的值是 application/x-www-form-urlencoded
 */
export const get =(vue,url,data)=>{
    vueObject = vue
	return request({
        url: url,
        method: 'get',
        params: data
      })
}
```
