通过vue实现添加axios组件,解决post传参数为null方面的问题（详细教程）

npm install axios --save

import axios from 'axios'
axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
axios.defaults.baseURL = 'http://localhost:7878/zkview';
Vue.prototype.$ajax = axios;

testGet: function () {
 this.$ajax({
 method: 'get',
 url: '/test/greeting',
 params: {
 firstName: 'Fred',
 lastName: 'Flintstone'
 }
 }).then(function (response) {
 console.log(response);
 }).catch(function (error) {
 console.log(error);
 });
},

testPost: function () {
 var params = new URLSearchParams();
 params.append('name', 'hello jdmc你好');
 params.append('id', '2');
 this.$ajax({
 method: 'post',
 url: '/test/greeting2',
 data:params
// data: {id: '3', name: 'abc'}
 }).then(function (response) {
 console.log(response);
 }).catch(function (error) {
 console.log(error);
 })
 }

var params = new URLSearchParams();
params.append('name', 'hello jdmc你好');
params.append('id', '2');
data:params

public Student greeting2(int id,String name) {

data: {id: '3', name: 'abc'}

public Object greeting2(@RequestBody Object student) {
