JavaScript-Submit form data to PHP with JS self-writing Ajax, but PHP $_post is empty?

, this is to receive the form data of the PHP controller, there is a form of data passed in, but $_REQUEST only $_GET the data in PHP, no $_POST data, which is why? (should not look at the code it?) If you need to see the code, say it, I'll fill it up again.

Notice that your request method is undefined, this place should be post.
You can:
1. Set the AJAX submission mode to post
2, it is best to set the form method to post,method= "POST"

$_post can get the data? Let's put the controller code on it.

To be added.
