//将$axios挂在原型上，以便在实例中能用 this.$axios能够拿到
Vue.prototype.$axios = axios;

3) Initiate a get request

this.$axios.get('/localhost/userinfo.php?userid=10001')
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });

<?php
header(&#39;Content-Type:application/json; charset=utf-8&#39;);
$arr = array(&#39;userid&#39;=>10001,&#39;name&#39;=>&#39;老马&#39;,&#39;age&#39;=>56);
