未定义的变量：HTTP_RAW_POST_DATA

Question

当我做的$一个简单的回声HTTP_RAW_POST_DATA我得到的错误：

Undefined variable: HTTP_RAW_POST_DATA 

，我读了在php.ini我需要取消选中

always_populate_raw_post_data = On 

但我仍然得到错误，我也重新启动了Apache。即时通讯使用PHP 5.3.6

Answer 1

如果您需要访问原始POST体你真的应该倾向于使用php://input流过$HTTP_RAW_POST_DATA按照该relevant manual entry：

php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST requests, it is preferable to use php://input instead of $HTTP_RAW_POST_DATA as it does not depend on special php.ini directives. Moreover, for those cases where $HTTP_RAW_POST_DATA is not populated by default, it is a potentially less memory intensive alternative to activating always_populate_raw_post_data. php://input is not available with enctype="multipart/form-data".

因此，访问POST体使用php://input：

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

Answer 2

如果你

Notice: Undefined variable: HTTP_RAW_POST_DATA

请打开你的服务器文件中添加找到

$server->service($HTTP_RAW_POST_DATA); 

，并与下面的2行更换。

if (!isset($HTTP_RAW_POST_DATA)) $HTTP_RAW_POST_DATA =file_get_contents('php://input'); 
$server->service($HTTP_RAW_POST_DATA); 

我希望这会有所帮助。
