vue項目報錯——$axios is no defined

vue項目報錯——$axios is no defined

1、在main.js中加入如下代碼：

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

2、在app.vue中改成：

this.$axios
      .get('http://localhost:8084/demo/user/userList')
      .then(response => (this.items = response))
      .catch(function (errer) {
        console.log(errer)
      })
