vue前端解决跨域

• 安装 axios

  cnpm install axios --save
  

• 在 config/index.js

  proxyTable: {
        '/api': {  //使用"/api"来代替"http://f.apiplus.c" 
          target: 'http://127.0.0.1:8000/', //源地址 
          changeOrigin: true, //改变源 
          pathRewrite: { 
            '^/api': '' //路径重写 
            } 
        } 
      },
  

• 在 src/main.js

  import axios from 'axios'
  Vue.prototype.axios = axios
  

• 在 src/components下新建文件 User.vue

  <template>
      <div>
          <h2>用户注册</h2>
          username: <input type='text' v-model='username'>
          password: <input type='password' v-model='password'>
          <button @click='register'>
              注册    
          </button>
      </div>
  </template>
  
  <script>
      export default{
          name:'user',
          data(){
              return {
                  username:'',
                  password:''
              }
          },
          methods:{
              register:function(){
                  var params = new URLSearchParams();
                  params.append('name',this.username);
                  params.append('password',this.password);
                  this.axios({
                      method:'post',
                      // api 是 http://127.0.0.1:8000 的简写
                      url:'api/app01/add/',
                      data:params
                  }).then(res=>{
                      console.log(res);
                  }).catch(error=>{
                      console.log(error);
                  })
              }
          }
      }
  </script>
  

• 在 router/index.js下

  import user from '@/components/User.vue'
  
  export default new Router({
    routes: [
      {
        path: '/',
        name: 'HelloWorld',
        component: HelloWorld
      },
      {
        path:'/user/register'，
        name:'user',
        component:user
      }
    ]
  })
