我知道还有很多其他类似的问题，但经过几天的尝试，我没有更多的想法来解决这个问题。
我第一次体验到Websocket连接，我需要建立一个简单的聊天，为此我正在尝试PHPWebSocketServer(https://github.com/ghedipunk/PHP-WebSockets)，所以我测试了这个聊天示例(https://github.com/Flynsarmy/PHPWebSocket-Chat)在我使用ws连接之前，一切都很好(这是一个已知的故事)。
对于我已经用pem签名的OpenSSL证书设置了Stunnel的WS，服务已经启动，端口(9040-9000)已经打开，websocket服务器正在正确地侦听端口9000(php./server.php)，但我不明白为什么在Stunnel.log中，每次浏览器客户端调用都会出现"坏证书"错误。
下面是所有可能有用的文件和日志。从Websocket php服务器文件开始：
server.php
<?php
// prevent the server from timing out
set_time_limit(0);
// include the web sockets server script (the server is started at the far bottom of this file)
require 'class.PHPWebSocket.php';
// when a client sends data to the server
function wsOnMessage($clientID, $message, $messageLength, $binary) {
global $Server;
$ip = long2ip( $Server->wsClients[$clientID][6] );
// check if message length is 0
if ($messageLength == 0) {
$Server->wsClose($clientID);
return;
}
//The speaker is the only person in the room. Don't let them feel lonely.
if ( sizeof($Server->wsClients) == 1 )
$Server->wsSend($clientID, "There isn't anyone else in the room, but I'll still listen to you. --Your Trusty Server");
else
//Send the message to everyone but the person who said it
foreach ( $Server->wsClients as $id => $client )
if ( $id != $clientID )
$Server->wsSend($id, "Visitor $clientID ($ip) said "$message"");
}
// when a client connects
function wsOnOpen($clientID)
{
global $Server;
$ip = long2ip( $Server->wsClients[$clientID][6] );
$Server->log( "$ip ($clientID) has connected." );
//Send a join notice to everyone but the person who joined
foreach ( $Server->wsClients as $id => $client )
if ( $id != $clientID )
$Server->wsSend($id, "Visitor $clientID ($ip) has joined the room.");
}
// when a client closes or lost connection
function wsOnClose($clientID, $status) {
global $Server;
$ip = long2ip( $Server->wsClients[$clientID][6] );
$Server->log( "$ip ($clientID) has disconnected." );
//Send a user left notice to everyone in the room
foreach ( $Server->wsClients as $id => $client )
$Server->wsSend($id, "Visitor $clientID ($ip) has left the room.");
}
// start the server
$Server = new PHPWebSocket();
$Server->bind('message', 'wsOnMessage');
$Server->bind('open', 'wsOnOpen');
$Server->bind('close', 'wsOnClose');
// for other computers to connect, you will probably need to change this to your LAN IP or external IP,
// alternatively use: gethostbyaddr(gethostbyname($_SERVER['SERVER_NAME']))
$Server->wsStartServer('0.0.0.0', 9000);

我的OpenSSL签名证书来自ssls(COMODO)CA，正如stunnel howto中所建议的那样，我使用了服务器机器的主机名作为通用名称，让我们称之为(mydomain.com)，但我还有另一个OpenSSL证书，使用了我网站的域名作为https模式的通用名称(www.mydomain.com)，我同时使用了这两个证书，但错误仍然相同。
无论如何，COMODO给我发了4个不同的文件，mydomain_com.crt，COMODARSADomainValidationSecureServerCA.crt，COMODRSAAddTrustCA.crt和AddTrustExternalCARoot.crt，我已经以这种方式将它们排序到stunnel.pem文件中。

我还尝试了openssl客户端连接
openssl s_client -connect xx.xx.xx.xx:9040
它起作用了！
请帮忙！
我也尝试过openssl客户端连接。。。它起作用了！
目前尚不清楚是什么在起作用：可能是连接和SSL握手在起作用。如果信任链对你起作用，你就会得到Verify return code: 0 (ok)。但是openssl s_client不做任何主机名检查，而浏览器做
Server=new FancyWebSocket('wss://xx.xx.xx.xx:9040')；
只有当您的证书实际上适用于给定的IP时，这才有效。但我怀疑您是否购买了特定IP的证书，因为通常会购买主机名的证书。由于您不使用证书中包含的名称访问服务器，主机名验证将失败。
