我有一个AJAX请求，发出以下信息（通过POST）。一切都很好，除了在请求的PHP文件中$_POST超全局为空。
我正在提供Firebug的标题和帖子标签：

很抱歉很长的帖子，谢谢！

正如polarblau建议我试过`echo file_get_contents（'php：// input'）;'输出以下内容：

这非常好，但我仍然不知道为什么我的$_POST没有填充。我甚至试图强迫$_SERVER['CONTENT_TYPE'] = 'multipart/form-data';但没有结果。
答案 0 :(得分：1)
This guy here似乎为这种情况提出了一个很好的调试方法：
$data = file_get_contents('php://input');
这应该会给你'原始传入消息'。如果这显示，您实际上有传入的数据，他建议强制使用内容类型，以防在发出请求时被搞乱：
if(empty($_SERVER['CONTENT_TYPE'])){
$type = "application/x-www-form-urlencoded";
$_SERVER['CONTENT_TYPE'] = $type;
}
