Vue 项目安装axios 模块

启动cmd 窗口指令，切换至Vue 项目的工作空间，执行如下指令：

cnpm install axios

Vue 项目设置反向代理：

修改 `src\main.js 文件如下所示:`

// 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ElementUI
    import ElementUI from 'element-ui'
    import 'element-ui/lib/theme-chalk/index.css'
    // 设置反向代理，前端请求默认发送到 http://localhost:7080/api
    var axios = require('axios')
    axios.defaults.baseURL = 'http://localhost:7080/api'
    // 全局注册，之后可在其他组件中通过 this.$axios 发送数据
    Vue.prototype.$axios = axios
    
    Vue.config.productionTip = false
    Vue.use(ElementUI)
    /* eslint-disable no-new */
    new Vue({
      el: '#app',
      router,
      components: { App },
      template: '<App/>'
    })

Vue 项目设置跨域

在 `config\index.js` 中，找到 proxyTable 位置，添加以下内容:

proxyTable: {
          '/api': {
            target: 'http://localhost:7080',
            changeOrigin: true,
            pathRewrite: {
              '^/api': ''
            }
          }
        },

项目实战：

编写src/components/Login.vue 组件和src/components/home/Appindex.vue 组件：

源码如下：

<template>
      <body id="poster">
      <el-form class="login-container" label-position="left"
               label-width="0px">
        <h3 class="login_title">系统登录</h3>
        <el-form-item>
          <el-input type="text" v-model="loginForm.username"
                    auto-complete="off" placeholder="账号"></el-input>
        </el-form-item>
        <el-form-item>
          <el-input type="password" v-model="loginForm.password"
                    auto-complete="off" placeholder="密码"></el-input>
        </el-form-item>
        <el-form-item style="width: 100%">
          <el-button type="primary" style="width: 100%;background: #505458;border: none" v-on:click="login">登录</el-button>
        </el-form-item>
      </el-form>
      </body>
    </template>
    
    <script>
        export default {
            name: "Login",
          data () {
            return {
              loginForm: {
                username: '',
                password: ''
              },
              responseResult: []
            }
          },
          methods: {
            login () {
              this.$axios
                .post('/login', {
                  username: this.loginForm.username,
                  password: this.loginForm.password
                })
                .then(successResponse => {
                  if (successResponse.data.code === 200) {
                    this.$router.replace({path: '/index'})
                  }
                })
                .catch(failResponse => {
                })
            }
          }
        }
    </script>
    
    <style scoped>
      #poster {
        background-position: center;
        height: 100%;
        width: 100%;
        background-size: cover;
        position: fixed;
      }
      body{
        margin: 0px;
      }
      .login-container {
        border-radius: 15px;
        background-clip: padding-box;
        margin: 90px auto;
        width: 350px;
        padding: 35px 35px 15px 35px;
        background: #fff;
        border: 1px solid #eaeaea;
        box-shadow: 0 0 25px #cac6c6;
      }
      .login_title {
        margin: 0px auto 40px auto;
        text-align: center;
        color: #505458;
      }
    </style>

<template>
      <div>
        Hello World!
      </div>
    </template>
    
    <script>
        export default {
            name: "Appindex"
        }
    </script>
    
    <style scoped>
    
    </style>

修改路由配置文件src/route/index.js

import Vue from 'vue'
    import Router from 'vue-router'
    import HelloWorld from '@/components/HelloWorld'
    // 导入刚才编写的组件
    import AppIndex from '@/components/home/AppIndex'
    import Login from '@/components/Login'
    
    Vue.use(Router)
    
    export default new Router({
      routes: [
        // 下面都是固定的写法
        {
          path: '/login',
          name: 'Login',
          component: Login
        },
        {
          path: '/index',
          name: 'AppIndex',
          component: AppIndex
        }
      ]
    })

项目主文件src/main.js

// 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ElementUI
    import ElementUI from 'element-ui'
    import 'element-ui/lib/theme-chalk/index.css'
    // 设置反向代理，前端请求默认发送到 http://localhost:8443/api
    var axios = require('axios')
    axios.defaults.baseURL = 'http://localhost:7080/api'
    // 全局注册，之后可在其他组件中通过 this.$axios 发送数据
    Vue.prototype.$axios = axios
    
    Vue.config.productionTip = false
    Vue.use(ElementUI)
    /* eslint-disable no-new */
    new Vue({
      el: '#app',
      router,
      components: { App },
      template: '<App/>'
    })
