vue使用axios

1.在mina.js中写下面代码

import Axios from "axios";
Vue.prototype.HOST = "http://localhost:4000";
Vue.prototype.$axios = Axios;

2.在页面使用的时候是

this.$axios

​    .post(this.HOST + "/api/login", {

​     username: this.username,

​     password: this.password

​    })

​    .then(*result* => {

​     console.log(result.data);

​     this.msg = result.data.msg;

​    })

​    .catch(*err* => {

​     console.log(err);

​    });
