PHP $HTTP_RAW_POST_DATA不适用于enctype ="multipart/form-data". http://www.php .net/manual/en/ini.core.php#ini.always-populate-raw-post-data

PHP $HTTP_RAW_POST_DATA is not available with enctype="multipart/form-data". http://www.php.net/manual/en/ini.core.php#ini.always-populate-raw-post-data

因此，现在在服务器上，请执行以下操作:

So, now on the server I do the following:

if (count($_POST == 0){
    $raw = file_get_contents('php://input');    
}else{
    $raw = '';
    foreach($_POST as $key => $value) {
        $raw = $raw.$key.'='.$value.'&';
    }
}

似乎正在工作.
