Php 使用Stunnel不会发生安全Websocket（wss）握手

我们制作了一个使用WebSocket的应用程序。我们已经用PHP构建了自己的websocket服务器，并使用Stunnel来使用安全的websocket。我们使用AmazonEC2媒体服务器

一切正常，直到上周chrome浏览器突然显示failed:WebSocket握手时出错：net:：ERR\u CONNECTION\u RESET。Firefox上的连接也已停止

但是，在wss连接确实发生时。它可能是在刷新页面4或5次之后，wss连接只发生一次

我们分析了该问题，以下是我们观察到的情况：

特技表演：

创建新的SSL会话后，一切正常。下面是日志

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

如果有人能帮助我们，那就太好了

到目前为止，我们为解决这个问题做了哪些工作：

• 已禁用Apache中的SSL缓存。问题仍然存在
• 在stunnel中使用了会话缓存设置。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楚的了解

我们下一步计划做什么

• 重新编译STUNNEL并尝试从代码中禁用SSL缓存

• 停止使用STUNNEL，了解如何在PHP中建立SSL连接。获得了类似于流\u上下文\u创建的内容来创建这些连接。然而，我们仍然必须看到流上下文创建的细节

• 将所有内容移动到新服务器，查看问题所在

希望我已经说清楚了。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个字节连接到完全读取）。“G”很可能是“GET”的第一个字节。我不确定是什么原因造成的，但我最近经历过这种情况。

先从流中读取1字节，然后执行完全读取（将1字节连接到完全读取）。“G”很可能是“GET”的第一个字节。我不知道是什么原因引起的，但我最近经历了这种情况。哇：这很有效！非常感谢约翰！我很惊讶这么简单的解决方案！这种情况在.NET中也发生过，它使用的是一个普通的

SslStream

。我认为这是因为缓冲区也包含关于TLS协商的数据，所以只有实际数据的第一个字节进入缓冲区。。。
