Add axios components through vue to solve the problem of null parameters in post (detailed tutorial)

Below I will share with you an article about adding axios components based on vue to solve the problem of null parameters in post. It has a good reference value and I hope it will be helpful to everyone.

Okay, the goods will be shipped below.

1. Install axios

npm install axios --save

2. Add axios component

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;

3. Get request

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);
 });
},

4. Post request

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);
    })
   }

5. Running result:

##6. Note:

There are two ways to pass parameters when using the post method, one is the normal method and the other is the json method. If the background accepts the normal method, then use the above method. Can.

Ordinary formed method

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

Backend receiving parameters:

public Student greeting2(int id,String name) {

json method

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

Background receiving parameters

public Object greeting2(@RequestBody Object student) {

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
