api.js文件代码

    import axios from 'axios'

    axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded'

    // 请求拦截器

    axios.interceptors.request.use(function(config) {

        return config;

      }, function(error) {

        return Promise.reject(error);

      })

      // 响应拦截器

    axios.interceptors.response.use(function(response) {

      return response;

    }, function(error) {

          return Promise.reject(error);

    })

    // 封装axios的post请求

    export function fetch(url, params) {

          return new Promise((resolve, reject) => {

            axios.post(url, params)

              .then(response => {

                resolve(response.data);

          })

          .catch((error) => {

                reject(error);

          })

      })

    }

    export default {

              mockdata(url, params) {

                return fetch(url, params);

      }

    }

 mock.js

    import Mock from 'mockjs' // 引入mockjs

    const Random = Mock.Random // Mock.Random 是一个工具类，用于生成各种随机数据

    let data = [] // 用于接受生成数据的数组

    let size = [

          '300x250', '250x250', '240x400', '336x280',

          '180x150', '720x300', '468x60', '234x60',

          '88x31', '120x90', '120x60', '120x240',

          '125x125', '728x90', '160x600', '120x600',

          '300x600'

    ] // 定义随机值

    for(let i = 0; i
