ajax請求不發送POST變量（或PHP腳本未接收到它們）

Question

我有一個AJAX請求，它通過POST發送以下信息。 除請求的PHP文件中$_POST超全局變量為空外，一切都很好。

我提供了Firebug的“標題”和“發布”標簽：

抱歉，很長的帖子，謝謝！

正如Polarblau建議的那樣，我嘗試了`echo file_get_contents（'php：// input'）;' 輸出以下內容：

這非常好，但是我仍然不知道為什么我的$_POST沒有被填充。 我什至嘗試強制$_SERVER['CONTENT_TYPE'] = 'multipart/form-data'; 但沒有結果。

bradino.com的 這個人似乎為這種情況建議了一種不錯的調試方法：

$data = file_get_contents('php://input');

這應該給您“原始傳入消息”。 如果這表明您實際上已經收到了數據，則他建議在提出請求時強制弄亂內容類型：

if(empty($_SERVER['CONTENT_TYPE'])){
     $type = "application/x-www-form-urlencoded";
     $_SERVER['CONTENT_TYPE'] = $type;
}
