mod_rewrite POST数据丢失。

Question

PHP 5.4.12

我使用以下的 .htaccess 文件

RewriteEngine On
RewriteBase /


RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule . /cap.php [L]

这是cap.php文件

var_dump($_SERVER['REQUEST_METHOD']);
var_dump($_POST);
die;

结果如下：

该结果为

string 'POST' (length=4)
array (size=0)
  empty

即：$_POST为空，为什么？

这是请求（来自Chrome开发工具）：

由于post没有以键值对的形式出现，因此$_POST为空。

在这种情况下，您应该执行以下操作：

if ( strtolower($_SERVER['REQUEST_METHOD']) == 'post' ) {
    $post = file_get_contents('php://input');
  }
