Question

我有一个使用WinSock2的cpp服务器，我试图用我的javascript客户端连接到这个服务器，但它不起作用，Chrome控制台说＆＃34; WebSocket握手期间出错：错误＆＃39; Sec-WebSocket-接受＆＃39;标题值＆＃34;。我将sha1和base64函数与在线sha1和base64进行了比较，所以问题不在这里。

Chrome响应标题：

HTTP/1.1 101 Switching Protocols
Upgrade: websocket
Connection: Upgrade
Sec-Websocket-Accept: NzdkYjg1Y2I4MDRlNTk0OGNmNzI1NzdjZDgwOTEwZWZiYWI1NzQ3Yw==

Chrome请求标头：

GET ws://localhost:8820/ HTTP/1.1
Host: localhost:8820
Connection: Upgrade
Pragma: no-cache
Cache-Control: no-cache
Upgrade: websocket
Origin: file://
Sec-WebSocket-Version: 13
User-Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36
Accept-Encoding: gzip, deflate, sdch, br
Accept-Language: he-IL,he;q=0.8,en-US;q=0.6,en;q=0.4
Sec-WebSocket-Key: Y7a2ZKEz/VCM92Wya49iPA==
Sec-WebSocket-Extensions: permessage-deflate; client_max_window_bits

服务器代码：

//key is already defined.
key += "258EAFA5-E914-47DA-95CA-C5AB0DC85B11";
key = sha1(key);
key = base64_encode(reinterpret_cast<const unsigned char*>(key.c_str()), key.length());

toClient = "HTTP/1.1 101 Switching Protocols\r\n";
toClient += "Upgrade: websocket\r\n";
toClient += "connection: Upgrade\r\n";
toClient += "Sec-Websocket-Accept: ";
toClient += key; 
toClient += "\r\n\r\n";

sendData(sc, toClient);

客户代码：

<!DOCTYPE HTML>

  <script type="text/javascript">
     function WebSocketTest()
     {
        if ("WebSocket" in window)
        {
           //alert("WebSocket is supported by your Browser!");

           // Let us open a web socket
           var ws = new WebSocket("ws://localhost:8820");
           console.log("test");
           ws.onopen = function()
           {
                alert("Connection.")
                // Web Socket is connected, send data using send()
                ws.send("20304user04user04user");
                //alert("Message is sent...");
           };

           ws.onmessage = function (evt) 
           { 
              var received_msg = evt.data;
              alert("Hey");
           };

           ws.onclose = function()
           { 
              // websocket is closed.
              alert("Connection is closed..."); 
           };
        }

        else
        {
           // The browser doesn't support WebSocket
           alert("WebSocket NOT supported by your Browser!");
        }
     }
  </script>

  <div id="sse">
     <a href="javascript:WebSocketTest()">Run WebSocket</a>
  </div>

我尝试手动构建响应：

串联的原始sha1摘要字节为77db85cb804e5948cf72577cd80910efbab5747c
以64为单位的字节：d9uFy4BOWUjPcld82AkQ77q1dHw=

这与你的不同。您正在将这些字节的十六进制字符串表示形式转换为base 64而不是将原始字节转换为base 64。

Websocket握手不起作用
