  • vue axios

    vue的作者在vue2.0发布之后宣告---停止对vue-resource的更新,推荐使用axios

    前段时间用了用,现在说说其基本用法.

    一.准备阶段 ----如果你只是个前端不会写接口或者你们要前后分离的话,你需要知道mock

    这里交个你一个超级简单的方式

    1.创建一个mock文件夹

    2.创建tree.json然后随便写点数据上去

    3.修改dev-server里面的配置---记住修改这里的时候在你运行npm run build 的时候不会被build 所以需要你和后端人员协商好路径问题 避免 404

    目录:bulid/dev-server

     二 . 安装

    //安装
    npm install axios

     三. 使用

    在src/components文件夹下创建 RainAxios.vue

    <template>
      <div>
        <div>msg: {{msg}}</div>
        <button @click='fn("../123")'>点击</button>
        <!--<audio autoplay="autoplay" src="audio/index.mp3"/>-->
      </div>
    </template>
    <style scoped>
    
    </style>
    <script>
      import Axios from 'axios'
      export default{
        data(){
          return {
            msg: 'hello Axios',
          }
        },
        components: {},
        methods: {
          fn: function () {
            var _this = this;
            Axios.get("./mock/tree.json")
              .then(function (rsp) {
                _this.msg = rsp.data.name
              })
          }
        }
      }
    </script>

    这个组件的需求很简单 ,  点击发送axios请求tree.json 并将返回值赋给msg 

     src/router/index.js

    import Vue from 'vue'
    import Router from 'vue-router'
    import Axios1 from '@/components/RainAxios'
    
    Vue.use(Router)
    
    export default new Router({
      routes: [
        {
          path: '/',
          name: 'Axios',
          component: Axios1
        }
      ]
    })

    不用我结识了吧  ----这是我最后一次写如此详细的教程了 

    以后只要是vue的东西都需要想想是否需要改router里面的东西

     点击后值改变

    如果你完成了上述功能 ---- 现在正式谈谈axios的用法了哦!!

    axios提供了以下方法

    axios.request(config)
    
    axios.get(url[, config])
    
    axios.delete(url[, config])
    
    axios.head(url[, config])
    
    axios.post(url[, data[, config]])
    
    axios.put(url[, data[, config]])
    
    axios.patch(url[, data[, config]])

    能看懂吧!

    不解释了!!!

    建议最好配置一下相关配置 ----英文不好就不帮你们翻译了免得误导你们

    {
      // “URL”是用于请求的服务器URL
      url: '/user',
     
      // 是在请求时使用的请求方法
      method: 'get', // 默认
     
      // baseURL  
      baseURL: 'https://some-domain.com/api/',
     
      // ` transformrequest ` 允许修改请求的数据后再发送到服务器
      transformRequest: [function (data) {
        // 做一些你想做的数据的改变
     
        return data;
      }],
     
      // `transformResponse` allows changes to the response data to be made before 
      // it is passed to then/catch 
      transformResponse: [function (data) {
        // Do whatever you want to transform the data 
     
        return data;
      }],
     
      // `headers` are custom headers to be sent 
      headers: {'X-Requested-With': 'XMLHttpRequest'},
     
      // `params` are the URL parameters to be sent with the request 
      // Must be a plain object or a URLSearchParams object 
      params: {
        ID: 12345
      },
     
      // `paramsSerializer` is an optional function in charge of serializing `params` 
      // (e.g. https://www.npmjs.com/package/qs, http://api.jquery.com/jquery.param/) 
      paramsSerializer: function(params) {
        return Qs.stringify(params, {arrayFormat: 'brackets'})
      },
     
      // `data` is the data to be sent as the request body 
      // Only applicable for request methods 'PUT', 'POST', and 'PATCH' 
      // When no `transformRequest` is set, must be of one of the following types: 
      // - string, plain object, ArrayBuffer, ArrayBufferView, URLSearchParams 
      // - Browser only: FormData, File, Blob 
      // - Node only: Stream 
      data: {
        firstName: 'Fred'
      },
     
      // `timeout` specifies the number of milliseconds before the request times out. 
      // If the request takes longer than `timeout`, the request will be aborted. 
      timeout: 1000,
     
      // `withCredentials` indicates whether or not cross-site Access-Control requests 
      // should be made using credentials 
      withCredentials: false, // default 
     
      // `adapter` allows custom handling of requests which makes testing easier. 
      // Return a promise and supply a valid response (see [response docs](#response-api)). 
      adapter: function (config) {
        /* ... */
      },
     
      // `auth` indicates that HTTP Basic auth should be used, and supplies credentials. 
      // This will set an `Authorization` header, overwriting any existing 
      // `Authorization` custom headers you have set using `headers`. 
      auth: {
        username: 'janedoe',
        password: 's00pers3cret'
      },
     
      // `responseType` indicates the type of data that the server will respond with 
      // options are 'arraybuffer', 'blob', 'document', 'json', 'text', 'stream' 
      responseType: 'json', // default 
     
      // `xsrfCookieName` is the name of the cookie to use as a value for xsrf token 
      xsrfCookieName: 'XSRF-TOKEN', // default 
     
      // `xsrfHeaderName` is the name of the http header that carries the xsrf token value 
      xsrfHeaderName: 'X-XSRF-TOKEN', // default 
     
      // `onUploadProgress` allows handling of progress events for uploads 
      onUploadProgress: function (progressEvent) {
        // Do whatever you want with the native progress event 
      },
     
      // `onDownloadProgress` allows handling of progress events for downloads 
      onDownloadProgress: function (progressEvent) {
        // Do whatever you want with the native progress event 
      },
     
      // `maxContentLength` defines the max size of the http response content allowed 
      maxContentLength: 2000,
     
      // `validateStatus` defines whether to resolve or reject the promise for a given 
      // HTTP response status code. If `validateStatus` returns `true` (or is set to `null` 
      // or `undefined`), the promise will be resolved; otherwise, the promise will be 
      // rejected. 
      validateStatus: function (status) {
        return status >= 200 && status < 300; // default 
      },
     
      // `maxRedirects` defines the maximum number of redirects to follow in node.js. 
      // If set to 0, no redirects will be followed. 
      maxRedirects: 5, // default 
     
      // `httpAgent` and `httpsAgent` define a custom agent to be used when performing http 
      // and https requests, respectively, in node.js. This allows to configure options like 
      // `keepAlive` that are not enabled by default. 
      httpAgent: new http.Agent({ keepAlive: true }),
      httpsAgent: new https.Agent({ keepAlive: true }),
     
      // 'proxy' defines the hostname and port of the proxy server 
      // `auth` indicates that HTTP Basic auth should be used to connect to the proxy, and supplies credentials. 
      // This will set an `Proxy-Authorization` header, overwriting any existing `Proxy-Authorization` custom headers you have set using `headers`. 
      proxy: {
        host: '127.0.0.1',
        port: 9000,
        auth: : {
          username: 'mikeymike',
          password: 'rapunz3l'
        }
      },
     
      // `cancelToken` specifies a cancel token that can be used to cancel the request 
      // (see Cancellation section below for details) 
      cancelToken: new CancelToken(function (cancel) {
      })
    }

    感觉没啥区别 玩不转的可以继续 jquery--$.ajax

     个人感觉npm中的教程不错  不过没有配合 vue-cli+webpack使用

    个人觉得使用vue使用express静态服务器有点low   然后来看看 如何使用json-server http://www.cnblogs.com/web-Rain/p/6520238.html
