//由于PHP默认只识别application/x-www.form-urlencoded标准的数据类型，因此，对型如text/xml的内容无法解析为$_POST数组，故保留原型，交给$GLOBALS['HTTP_RAW_POST_DATA'] 来接收。

//另外还有一项 php://input 也可以实现此这个功能

//php://input 允许读取 POST 的原始数据。和 $HTTP_RAW_POST_DATA 比起来，它给内存带来的压力较小，并且不需要任何特殊的 php.ini 设置。php://input 不能用于 enctype="multipart/form-data"。
