WebSocket菜鸟教程 WebSocket菜鸟教程 看到这想必你了解了webscoket,基本文档原理就不提了！ 这张图你能看明白吗？不能没事还有一张更简单的 搞懂这个图很关键，我们与人聊天不是在面对面聊天，其实在于服务器聊天，传统的http是客户端发起请求服务器响应请求，重点是服务器无法给客户端发起请求. Turning on the debug flag on the server code, I. Luckily, C# has a TcpListener class which does as the name suggests. 而 websocket 是二进制协议，一个字节可以用来存储很多信息： 比如协议的第一个字节，就存储了 FIN（结束标志）、opcode（内容类型是 binary 还是 text） 等信息。 第二个字节存储了 mask（是否有加密），payload（数据长度）。 仅仅两个字节，存储了多少信息呀！ 这就是二进制协议比文本协议好的地方。 我们看到的 weboscket 的 message 的收发，其实底层都是拼成这样的格式。 只是浏览器帮我们解析了这种格式的协议数据。 这就是 weboscket 的全部流程了。 其实还是挺清晰的，一个切换协议的过程，然后是二进制的 weboscket 协议的收发。 那我们就用 Node. opcode attribute represents one of enum value, list of possible values is described in Opcodes section. Today I decided to look at the WebSocket code and I found why my WebSocket closed directly. Learn more about the Microsoft. lear corporation turnover brocade switch port commands.
