Note: The request address is your own project address, please change it yourself.
This is just a simple use of native XMLHttpRequst. Later, I will post how to encapsulate native ajax to implement jequery's ajax
The first step: Create an xhr object.
const xhr = new XMLHttpRequest();
The second step: open() settings.
xhr.open('PUT','http://118.24.84.199:8080/sm/accept/list',false);
Step 3: Set the headers required by the interface.
xhr.setRequestHeader('token','515b8c62-ddf4-41ef-a7c8-93957e1c589e'); xhr.setRequestHeader('Accept','application/json'); xhr.setRequestHeader('Content-Type','application/json');
Step 4: Send request data.
Note: The data here needs to be processed as a json file and processed using JSON.stringify.
let data = { page:1, pageSize:10, }; data = JSON.stringify(data); xhr.send(data);
It has been sent here, and you can check the request status in the browser's network request.
But the data has not been processed in the page yet
If the data is a synchronous request: process the data directly after the send() statement.
console.log(xhr.response);
But in general, data requests are asynchronous, so the onreadystatechange event must be used to process the data.
Print the data after receiving it.
xhr.onreadystatechange = function(event){ if (xhr.readyState == 4){ if ((xhr.status >= 200 && xhr.status < 300) || xhr.status == 304){ console.log(JSON.parse(xhr.response)); } else { console.log("Request was unsuccessful: " + xhr.status); } } };

Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
