POCO 1.5.1 Websocket客户端无法连接到c#Websocket服务器

c# c++ websocket

POCO 1.5.1 Websocket客户端无法连接到c#Websocket服务器,c#,c++,websocket,poco,eventmachine,C#,C++,Websocket,Poco,Eventmachine,问题: websocket客户端（POCO 1.5.1，c++）将不会连接到websocket c#服务器（带有Fleck库的命令行应用程序）。到达超时时抛出异常： Cannot upgrade to WebSocket connection: OK Exception Code: 1 Poco WebException Documentation WS_ERR_NO_HANDSHAKE = 1 : No Connection: Upgrade or Upgrade: websocket h

问题:

websocket客户端（POCO 1.5.1，c++）将不会连接到websocket c#服务器（带有Fleck库的命令行应用程序）。到达超时时抛出异常：

Cannot upgrade to WebSocket connection: OK
Exception Code: 1

Poco WebException Documentation
WS_ERR_NO_HANDSHAKE = 1 : 
No Connection: Upgrade or Upgrade: websocket header in handshake request.
事实1：这个websocket客户端将连接到一个Ruby事件机websocket服务器

事实2:javascript客户端将连接到websocket c服务器

事实3：相同的javascript客户端也将连接到websocket ruby服务器

事实4：websocket客户端将不会连接到Alchemy websocket服务器附近

使用Wireshark更新 POCO正在使用 GET/HTTP/1.0\r\n

Javascript版本： GET/HTTP/1.1\r\n

所有源代码 C++中的客户端代码
问题是POCO默认HTTP请求版本为1.0

RFC规范第4.1节指出，最小值为1.1：

  • 请求的方法必须是GET，HTTP版本必须是GET 至少为1.1。 例如，如果WebSocket URI为“ws://example.com/chat”， 发送的第一行应该是“GET/chat HTTP/1.1”
    • 通过将HTTPRequest结构替换为：

    HTTPRequest request(HTTPRequest::HTTP_GET, "/ws", "HTTP/1.1" );
    干杯

    您得到的确切错误代码是什么？您从哪里得到的？有趣的是，服务器在客户端超时之前检测到客户端连接。>>2013年11月24日下午4:30:01【调试】客户端从127.0.0.1:64699连接2013年11月24日下午4:30:01【调试】155字节读取与POCO异常文档交叉引用：WS_ERR_NO_HANDSHAKE=1无连接：升级或升级：握手请求中的websocket头。在POCO源代码中，这个错误意味着服务器没有包含Upgrade:websocket头。您应该使用数据包嗅探器（如Wireshark）来查看TCP对话。使用斑点或炼金术似乎可以与HTML/javascript客户端一起工作。我觉得POCO是这里的问题。
