问题描述

https://stackoverflow.com/a/6727354/462608

简短答案:
io.sockets.adapter.rooms

The short answer:
io.sockets.adapter.rooms

我分析了io:

该答案中所示的io的套接字输出部分包含以下内容:

The sockets output part from io as shown in that answer contains the following:

sockets: 
   { manager: [Circular],
     name: '',
     sockets: { '210837319844898486': [Object] },
     auth: false,
     flags: { endpoint: '', exceptions: [] },
     _events: { connection: [Function] } },

适配器在哪里?房间在哪里?

从 io 的输出中找出适配器和房间的方法是什么?

What is the way to find out adapter and rooms from the output of io?

    console.log("Server-Client Connected!");
    socket.join("_room" + room_id);
    socket.on('connected', function (data) {

    });
    console.log(io.sockets.adapter.rooms);
    socket.on('qr_code_scan', function (room_id) {
        io.sockets.in("_room" + room_id).emit("qr_code_scan", true);
    });
});
