function request_by_curl($remote_server, $post_string) {  
    $ch = curl_init();  
    curl_setopt($ch, CURLOPT_URL, $remote_server);
    curl_setopt($ch, CURLOPT_POST, 1); 
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, array ('Content-Type: application/json;charset=utf-8'));
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  
    curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0); 
    curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
    $data = curl_exec($ch);
    curl_close($ch);                
    return $data;  
}
function boxmoe_msg_comment($comment_id){
    $comment = get_comment($comment_id);

			$time    = intval(microtime(true) * 1000);
			$secret  = '机器人加签秘钥';
