Flask Socket.io服务器上的Node.js Socket.io客户机

Question

我试图将Node.js Socket.io客户机连接到Python/Flask Socket.io服务器。

在服务器（Raspberry Pi）上运行这个项目：pi-gpio-server。这个项目已经有了一个内置的网站，这是一个socket.io客户机来访问Raspberry PI的引脚。整个项目运作良好。

if __name__ == '__main__':
    socketio.run(app, host="192.168.0.8", port=5000)

var io = require('socket.io-client');
var socket = io.connect('http://192.168.0.8:5000', {path: '/', transports: ['websocket']});

socket.on( 'connect', (socket) => {
    console.log('Connected: ');
    console.log(socket);
});

socket.on( 'pins:list', (list) => {
    console.log('List of Pins: ');
    console.log(list);
});

有什么想法吗，为什么我找不到联系？在Flask服务器中有客户机的限制吗？有什么特别的命令要发吗？是否有可能调试连接？

@Christoph请使用下面的代码，你应该可以连接...我有Flash服务器运行和Nodejs作为客户端，它对我来说很好！！！在我的例子中，我在同一台机器上运行服务器和客户机，所以我用localhost代替IP地址

const socket = require('socket.io-client')('http://192.168.0.8:5000', {
            reconnection: true,
            reconnectionDelay: 10000
          });
    
        socket.on('connect', (data) => {
            console.log('Connected to Socket');
        });
        
        socket.on('event_name', (data) => {
            console.log("-----------------received event data from python flask srver");
        });
    
        //either 'io server disconnect' or 'io client disconnect'
        socket.on('disconnect', (reason) => {
            console.log("client disconnected");
            if (reason === 'io server disconnect') {
              // the disconnection was initiated by the server, you need to reconnect manually
              console.log("server disconnected the client, trying to reconnect");
              socket.connect();
            }else{
                console.log("trying to reconnect agan with server");
            }
            // else the socket will automatically try to reconnect
          });
    
        socket.on('error', (error) => {
            console.log(error);
        });
