我知道还有很多其他类似的问题，但经过几天的尝试，我没有更多解决问题的想法。

我第一次体验 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例如（https://github.com/Flynsarmy/PHPWebSocket-Chat），一切正常，直到我使用 ws 连接（这是一个已知的故事）。

对于 wss，我使用 pem 签名的 OpenSSL 证书设置了 Stunnel，服务已启动，端口 (9040 - 9000) 已打开，并且 websocket 服务器正确侦听端口 9000 (php ./server.php)，但是我无法弄清楚为什么在 stunnel.log 中每个浏览器客户端调用中总是出现“错误证书”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：

服务器.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，我使用服务器机器的主机名作为通用名称，我们称之为（mydomain.com），但我还有另一个 OpenSSL 证书我网站的域名作为 https 模式的通用名称（www.mydomain.com），我都使用过，但错误仍然相同。

无论如何，COMODO 向我发送了 4 个不同的文件，mydomain_com.crt、COMODORSADomainValidationSecureServerCA.crt、COMODORSAAddTrustCA.crt、AddTrustExternalCARoot.crt，我已经以这种精确的方式将它们分类到 stunnel.pem 文件中。

我也试过openssl客户端连接

openssl s_client -connect xx.xx.xx.xx:9040

它有效！

请帮忙！

我也试过openssl客户端连接......它工作！

目前尚不清楚什么在起作用：可能连接和 SSL 握手正在工作。如果信任链对您有用，请获取Verify return code: 0 (ok). 但openssl s_client不做任何主机名检查，而浏览器做。

服务器 = new FancyWebSocket('wss://xx.xx.xx.xx:9040');

仅当您的证书实际上是针对给定 IP 时，这才有效。但我怀疑您是否为特定 IP 购买了证书，因为通常会为主机名购买证书。由于您没有通过证书中包含的名称访问服务器，因此主机名验证将失败。
