未定義的變量：HTTP_RAW_POST_DATA

Question

當我做的$一個簡單的回聲HTTP_RAW_POST_DATA我得到的錯誤：

Undefined variable: HTTP_RAW_POST_DATA 

，我讀了在php.ini我需要取消選中

always_populate_raw_post_data = On 

但我仍然得到錯誤，我也重新啓動了Apache。即時通訊使用PHP 5.3.6

Answer 1

如果您需要訪問原始POST體你真的應該傾向於使用php://input流過$HTTP_RAW_POST_DATA按照該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，訪問POST體使用php://input：

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

Answer 2

如果你

Notice: Undefined variable: HTTP_RAW_POST_DATA

請打開你的服務器文件中添加找到

$server->service($HTTP_RAW_POST_DATA); 

，並與下面的2行更換。

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

我希望這會有所幫助。
