要解决的就是server代码的跨域问题

原装写法：

解决写法：

// 喜欢组合语法的自己组
const io = new ioServer.Server(httpApp, {
    cors: {
        origin: "*"
    }
});

io.on('connection', function(socket) {
    RTCMultiConnectionServer.addSocket(socket, config);

    // ----------------------
    // below code is optional

    const params = socket.handshake.query;

    if (!params.socketCustomEvent) {
        params.socketCustomEvent = 'custom-message';
    }

    socket.on(params.socketCustomEvent, function(message) {
        socket.broadcast.emit(params.socketCustomEvent, message);
    });
});

ok齐活搞定不谢
