棘轮客户端身份验证失败
我是网络套接字编程的新手。我正在 codeigniter 中实现网络套接字以实现简单的聊天功能，我的配置如下
$config['ratchet_client'] = array(
'host' => '127.0.0.1', // Default host
'port' => 8282, // Default port (be careful to set unused server port)
'auth' => true, // If authentication is mandatory
'debug' => true // Better to set as false in Production
);
现在当我在终端上启动服务器时它显示
Running server on host 127.0.0.1:8282
Authentication activated
但是当我加载 html 时，它会在终端上显示以下内容
New client connected as (81)
Client (81) authentication failure
Client (81) authentication success
Client (81) disconnected
一次所有四行，在我的控制台上，我收到以下消息
更新我的 Ratchet_client.php（在库文件夹中）是
<?php

1 个答案:
答案 0 :(得分：0)
这是一个非常愚蠢的错误，因为我正在检查
if (empty($auth) or !is_integer($auth))
我的 is_integer($auth) 失败了，所以我在 if 语句之前添加了 $auth=(int)$auth; 并且问题解决了...
