JS exports the file via GET POST download

Sometimes, we need to GET or POST to download the file, and the stream returned directly from the backend can be downloaded directly through the browser using the GET method if there is no authentication, but because authentication is required, it is not the verification of cookies, which makes things a bit troublesome.
The renderings are as follows:

js code:

Login is visible.

Resources:

The hyperlink login is visible.
The hyperlink login is visible.

xhrReq.open(method, url);
xhrReq.open(method, url, async);
xhrReq.open(method, url, async, user);
xhrReq.open(method, url, async, user, password);

async can select an optional boolean parameter to indicate whether the operation is performed asynchronously, which defaults to true. If the value is false, the send() method will not return until an answer is received. If true, notifications of completed transactions are available to event listeners. If the multipart property is true, this must be true, otherwise an exception will be thrown.
