Javascript Websocket握手不起作用
我有一个使用WinSock2的cpp服务器，我试图用我的javascript客户端连接到此服务器，但它不工作，chrome控制台显示“WebSocket握手时出错：错误的'Sec WebSocket Accept'头值”。 我将我的sha1和base64函数与联机sha1和base64进行了比较，因此问题不在这里 Chrome响应标题：Javascript Websocket握手不起作用,javascript,c++,websocket,Javascript,C++,Websocket,我有一个使用WinSock2的cpp服务器，我试图用我的javascript客户端连接到此服务器，但它不工作，chrome控制台显示“WebSocket握手时出错：错误的'Sec WebSocket Accept'头值”。 我将我的sha1和base64函数与联机sha1和base64进行了比较，因此问题不在这里 Chrome响应标题： HTTP/1.1 101 Switching Protocols Upgrade: websocket Connection: Upgrade Sec-Webs
