I created an API on the PHP side, and when I try to get the JSON data sent by POST, I couldn’t receive the POST data with
$ _POST, so make a note.
According to the official, $ _POST can be received when the “HTTP Content-Type” is as follows.
application/x-www-form-urlencoded or multipart/form-data
application/json couldn’t be received in $ _POST.
How to use JSON sent by POST to PHP as data
This is how to retrieve the actually POSTed data.
// get raw data from the request $json = file_get_contents('php://input'); // Converts json data into a PHP object $data = json_decode($json, true);
