• 前后端分离之mockjs实战demo


    基于vue-cli+webpack的demo
    项目结构


    axios文件夹用来创建axios相关配置:

    import axios from 'axios'
    import vue from 'vue'
     
    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 {
      JH_news(url, params) {
        return fetch(url, params);
      }
    }
    

    mock文件夹建立mock数据,配置mock请求:

    // 引入mockjs
    const Mock = require('mockjs');
    // 获取 mock.Random 对象
    const Random = Mock.Random;
    // mock一组数据
    const produceNewsData = function() {
        let articles = [];
        for (let i = 0; i < 10; i++) {
            let newArticleObject = {
                title: Random.csentence(5, 30), //  Random.csentence( min, max )
                thumbnail_pic_s: Random.dataImage('300x250', 'mock的图片'), // Random.dataImage( size, text ) 生成一段随机的 Base64 图片编码
                author_name: Random.cname(), // Random.cname() 随机生成一个常见的中文姓名
                date: Random.date()  // Random.date()指示生成的日期字符串的格式,默认为yyyy-MM-dd;
            }
            articles.push(newArticleObject)
        }
     
        return {
            articles: articles
        }
    }
     
    // Mock.mock( url, post/get , 返回的数据);
    Mock.mock('/news/index', 'post', produceNewsData);
    

    HelloWorld.vue页面首页:

    <template>
      <div class="index">
        <div v-for="(item, key) in newsListShow" :key="key">
          <news-cell
          :newsDate="item"
          ></news-cell>
        </div>
      </div>
    </template>
     
    <script>
    import api from 'js/axios/config'
    import NewsCell from './NewsCell.vue'
     
    export default {
      name: 'index',
      data () {
        return {
          newsListShow: [],
        }
      },
      components: {
        NewsCell
      },
      created() {
        this.setNewsApi();
      },
      methods:{
        setNewsApi: function() {
          api.JH_news('/news/index', 'type=top&key=123456')
          .then(res => {
            console.log(res);
            this.newsListShow = res.articles;
          });
        },
      }
    }
    </script>
     
    <!-- Add "scoped" attribute to limit CSS to this component only -->
    <style scoped>
    
    </style>
    

    NewsCell.vue组件渲染数据:

    <template>
      <div class="wrap">
        <div class="wrap-top">
          <h1>{{newsDate.title}}</h1>
          <span class="date">{{newsDate.date}}</span>
        </div>
        <div class="wrap-bottom">
          <span class="name">{{newsDate.author_name}}</span>
          <img :src="newsDate.thumbnail_pic_s" alt="">
        </div>
      </div>
    </template>
     
    <script>
    export default {
      name: 'NewsCell',
      props: {
        newsDate: Object
      },
      data () {
        return {
        }
      },
      computed: {
      },
      methods: {
        jumpPage: function () {
          window.location.href = this.newsDate.url
        }
      }
    }
    </script>
     
    <style scoped>
      .wrap{
         100%;
        font-size: 0.3rem;
      }
      .wrap-top,.wrap-bottom{
        display: flex;
        align-items: center;
        justify-content:space-between;
      }
      h1{
         6rem;
        text-align: left;
        white-space: nowrap;
        text-overflow: ellipsis;
        overflow: hidden;
      }
      .date{
         4rem;
      }
      .name{
        flex: 1;
      }
      img{
         10rem;
      }
    </style>
    

    main.js入口文件:

    // The Vue build version to load with the `import` command
    // (runtime-only or standalone) has been set in webpack.base.conf with an alias.
    import Vue from 'vue'
    import App from './App'
    import router from './router'
    // 引入mockjs
    require('js/mock/mock.js')
    Vue.config.productionTip = false
    
    /* eslint-disable no-new */
    new Vue({
      el: '#app',
      router,
      components: { App },
      template: '<App/>'
    })
    
    
    运行结果
