Question

我们制作了一个使用websockets的应用程序。我们在PHP中构建了自己的websocket服务器，并使用Stunnel来使用安全的websockets。我们使用Amazon EC2 Medium Server

直到上周，Chrome浏览器开始显示失败时，每件事情都运行良好：WebSocket握手期间出错：net :: ERR_CONNECTION_RESET。连接也已停止在Firefox上发生。

然而，wss连接确实发生了。当我们刷新页面时，它可能会在4或5次之后，wss连接发生一次。

我们已经分析了这个问题，以下是我们观察到的事情：

在STUNNEL：

创建新的SSL会话时，一切正常。以下是日志

在我们的PHP WebSocket服务器中：

当会话重用发生时，WebSocket服务器只获取字符串'G'作为数据而没有其他内容，因此握手失败。但是，当在Stunnel中创建新会话时，握手工作正常。

如果有人可以帮助我们，那就太好了。

到目前为止，我们已采取了哪些措施来解决这个问题：

在Apache中禁用SSL缓存。问题仍然存在
stunnel中使用的会话缓存设置。问题仍在那里。此外，我们还没有清楚地了解会话缓存设置以及如何禁用它。

我们计划下一步做什么

重新编译STUNNEL并尝试从代码中禁用SSL缓存。
停止使用STUNNEL并了解如何在PHP中建立SSL连接。有类似 stream_context_create 的东西来创建这些连接。但是我们仍然需要查看stream_context_create
将所有内容移至新服务器并查看问题所在。

希望我已经说清楚了。等待回复。谢谢！

Answer 1

首先从流中读取1个字节，然后执行完整读取（将1个字节连接到完整读取）。＆＃34; G＆＃34;很可能是＆＃34; GET＆＃34;的第一个字节。我不知道是什么原因造成的，但我最近经历过这种情况。

Secure Websocket（wss）使用Stunnel不会发生握手
