我们做了一个使用 websockets 的应用程序。我们已经在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 中型服务器
一切都运行良好，直到上周突然 chrome 浏览器开始显示失败：WebSocket 握手期间的错误：net：：ERR_CONNECTION_RESET。连接也已停止在火狐上发生。
但是，在 wss 连接确实会发生时。就像我们刷新页面时可能会在 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：
在隧道中：
创建新的 SSL 会话后，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，当在隧道中创建新会话时，握手工作正常。
如果有人能帮助我们，那就太好了。
到目前为止，我们做了什么来解决这个问题：
- 在 Apache 中禁用了 SSL 缓存。问题仍然存在
- 在隧道中使用会话缓存设置。问题仍然存在。此外，我们对会话缓存设置以及如何禁用它也没有清晰的了解。
我们下一步计划做什么
重新编译 STUNNEL 并尝试从代码禁用 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，我们仍然必须看到stream_context_create的细节
将所有内容移动到新服务器，看看问题所在。
希望我已经把事情说清楚了。等待答复。谢谢！
首先从
流中读取 1 个字节，然后执行完全读取(将 1 个字节连接到完整读取(。"G"很可能是"GET"的第一个字节。我不确定是什么原因造成的，但我最近经历了这种情况。
