Send GET or POST base64 request from Javascript to PHP?

Question

PHP

There is a String received using the function, the
reader.readAsDataURL(blob)
size is somewhere around 500kb.

I need to send this string using the API from JS to PHP using XMLHttpRequest.
Everything is ready, except that this string is not transmitted (apparently the volume is large)

Smaller strings are passed

How can I transfer it?

In two steps (more economical!):

You can do it in one:

var xhr = new XMLHttpRequest();
xhr.open('POST', 'someURLForTheUpload', true); //my url had the ID of the item that the blob corresponded to
xhr.responseType = 'Blob';
xhr.setRequestHeader("x-csrf-token",csrf); //if you are doing CSRF stuff
xhr.onload = function(e) { /*irrelevant code*/ };
xhr.send(blob);
