的PHP 5.4.12

我使用以下.htaccess

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;

结果是

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

即$_POST为空,为什么？

这是请求(来自chrome dev工具)

解决方法:

$_POST为空,因为该帖子不是key：value格式.

在这种情况下,你应该做

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