What is the usage of axios in vuejs?

Basic usage of axios in vue

1. First install axios:

1)：npm install

2)：npm install vue-axios --save

3)：npm install qs.js --save　　//这一步可以先忽略，它的作用是能把json格式的直接转成data所需的格式

2. After successful installation, quote on the main.js page:

import Vue from 'vue'
import axios from 'axios'
Vue.prototype.$axios = axios    //全局注册，使用方法为:this.$axios
Vue.prototype.qs = qs           //全局注册，使用方法为:this.qs

3 Finally start using the request:

<script>
    export default{
        data(){
            return{
                userId:666,
　　　　　　　　　 token:&#39;&#39;,
            }
        },
        created(){
            this.$axios({
                method:&#39;post&#39;,
                url:&#39;api&#39;,
                data:this.qs.stringify({    //这里是发送给后台的数据
                      userId:this.userId,
                      token:this.token,
                })
            }).then((response) =>{          //这里使用了ES6的语法
                console.log(response)       //请求成功返回的数据
            }).catch((error) =>
                console.log(error)       //请求失败返回的数据
            })
        }
    }
</script>

Initiate multiple requests at the same time

function getUserAccount() {
  return axios.get('/user/12345');
}

function getUserPermissions() {
  return axios.get('/user/12345/permissions');
}

axios.all([getUserAccount(), getUserPermissions()])
  .then(axios.spread(function (acct, perms) {
    // Both requests are now complete
  }));

创建一个实例
你可以创建一个拥有通用配置的axios实例

axios.creat([config])
var instance = axios.create({
  baseURL: 'https://some-domain.com/api/',
  timeout: 1000,
  headers: {'X-Custom-Header': 'foobar'}
});
