原因: Flask如果用默认的启动方式,就会报404,如果使用服务器启动,那就可以连接成功。简单来说不支持默认方式启动,你可以用任何第三方中间件或者是专业的服务器来启动Flask框架 最简单的解决方式: #加入wsgi中间件 app.wsgi_app = LighttpdCGIRootFix(app.wsgi_app) #启动flask io.run(app) 1. 2. 3. 4....
它结合了Flask和Socket.IO,使得开发者可以轻松地构建具有实时功能的Web应用程序。 错误请求(400 Bad Request)是指客户端发送的请求有语法错误或无法被服务器理解。在Flask-SocketIO中,当客户端发送的请求无效时,服务器会返回400错误。 会话无效是指在Flask-SocketIO中,客户端的会话(session)无效或过期。会话是指在...

That would normally mean that a request timed out on the client side. If you check the access logs, perhaps you'll see some 404 errors there when the client-side JavaScript is trying to poll a non-existent view? giles | 12492 posts | PythonAnywhere staff |May 22, 2019, 4:26 p.m.|...
The response had HTTP status code 404" - javascript I'm getting the above error for both Safari 8.0.2 and Chrome 44.0.x. I'm still trying to find out if it's a problem with my apache config, but the exact config I'm using seemed to work with flask-socketio 0.6.0 #11 Cesco ...
版本不匹配:WebSocket有多个版本,服务器和客户端需要使用相同的版本进行握手。如果版本不匹配,握手过程中就会出错。 协议不支持:有些网络环境或代理服务器可能不支持WebSocket协议,导致握手过程中出错。在这种情况下,可以考虑使用其他的实时通信方式,如长轮询或Server-Sent Events。
