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

Copy after login

2. Add axios component

import axios from &#39;axios&#39;
axios.defaults.headers.post[&#39;Content-Type&#39;] = &#39;application/x-www-form-urlencoded&#39;;
axios.defaults.baseURL = &#39;http://localhost:7878/zkview&#39;;
Vue.prototype.$ajax = axios;

Copy after login

3. Get request

testGet: function () {
 this.$ajax({
  method: &#39;get&#39;,
  url: &#39;/test/greeting&#39;,
  params: {
   firstName: &#39;Fred&#39;,
   lastName: &#39;Flintstone&#39;
  }
 }).then(function (response) {
  console.log(response);
 }).catch(function (error) {
  console.log(error);
 });
},

Copy after login

4. Post request

testPost: function () {
    var params = new URLSearchParams();
    params.append(&#39;name&#39;, &#39;hello jdmc你好&#39;);
    params.append(&#39;id&#39;, &#39;2&#39;);
    this.$ajax({
     method: &#39;post&#39;,
     url: &#39;/test/greeting2&#39;,
     data:params
//     data: {id: &#39;3&#39;, name: &#39;abc&#39;}
    }).then(function (response) {
     console.log(response);
    }).catch(function (error) {
     console.log(error);
    })
   }

Copy after login

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(&#39;name&#39;, &#39;hello jdmc你好&#39;);
params.append(&#39;id&#39;, &#39;2&#39;);
data:params

Copy after login

Backend receiving parameters:

public Student greeting2(int id,String name) {

Copy after login

json method

data: {id: &#39;3&#39;, name: &#39;abc&#39;}

Copy after login

Background receiving parameters

public Object greeting2(@RequestBody Object student) {

Copy after login

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