Попытка сделать простой запрос xhr с несколькими переменными и длинным JSON.Когда я var_dump($_POST), var_dump($_REQUEST) или var_dump(file_get_contents('php://input')), я получаю это: 

array(1) {
  ["------WebKitFormBoundarySaVZDjpQjjwsAOHs

}

Но как только я пытаюсь получить доступ к полям, я получаю NULL: (

I 'мы пробовали разные типы контента (multipart / form-data, application / x-www-form-urlencoded или нет)

xhr : 

    var xhr = new XMLHttpRequest();
    xhr.open('POST', resultsURL, true);
        xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
    xhr.onload = function () {
        // do something to response
        console.log(this.responseText);
    };

    var dataSave = new FormData();

    dataSave.append('document_id', documentId);
    dataSave.append('project_id', projectId);
    dataSave.append('user_id', userId);
    dataSave.append('stage', stage);
    dataSave.append('show_save_button', showSaveButton);
    dataSave.append('id_user_associatedDoc', idUserAssociatedDoc);
    dataSave.append('annotation', JSON.stringify(json));

    xhr.onreadystatechange = function() {
        switch(xhr.readyState) {
            case XMLHttpRequest.OPENED:
            case XMLHttpRequest.LOADING:
                if(callbackLoading)
                    callbackLoading();
                break;
            case XMLHttpRequest.DONE:

                    console.log("XMLHttpReques.responseText:");
                    console.log(xhr.responseText);


                break;
        }
    }

    xhr.send(dataSave);

По результатамURL php : 

    $docId = $_REQUEST['document_id'];
    echo var_dump($docId); //returns NULL

Разве это не должно работать? Знаете, что я могу делать неправильно?

multipart / form-data

new FromData - это multipart / form-data с границей (https://www.w3.org/Protocols/rfc1341/7_2_Multipart.html). вы не должны устанавливать какие-либозаголовок типа содержимого. Заголовок будет установлен браузером. Вы можете получить доступ к данным с помощью $_POST или $_REQUEST.

application / x-www-form-urlencoded

если вы используете application / x-www-form-urlencoded, вы должны отправить закодированный URL-адрес. 

xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');

// ...

function encodeForm(dataSave) {
  bar r = [];
  dataSave.forEach((v,k) => {
    r.push(encodeURIComponent(k) + '=' + encodeURIComponent(v));
  });
  return r.join('&');
}
xhr.send(encodeForm(dataSave));

вы можете получить доступ к данным с помощью $ _POST или $ _REQUEST

application / x-www-form-urlencoded имеет меньше накладных расходов.
