javascript - NodeJs socket.io让所有客户端都进入房间

在以下功能上使用io.sockets.adapter.rooms[room]可以获取特殊房间的所有套接字ID，现在我尝试将套接字ID推送为房间客户端，但是不幸的是，当我尝试在undefined上使用socketIds[i]时cc>

例如：

socketIds:{"sockets":{"yJJj6ysKEPp0UhOdAAAA":true,"9dDHXedsMRrjJNhrAAAB":true},"length":2}

如何使用clients.push(chatClients[socketIds[i]]);从sockets中获取所有socketIds？

function getClientsInRoom(socketId, room) {
    // get array of socket ids in this room
    var socketIds = io.sockets.adapter.rooms[room];
    console.log("socketIds:" + JSON.stringify(socketIds));
    var clients = [];

    if (socketIds && socketIds.length > 0) {
        //socketsCount = socketIds.lenght;

        // push every client to the result array
        for (var i = 0, len = socketIds.length; i < len; i++) {

            // check if the socket is not the requesting
            // socket
            if (socketIds[i] != socketId) {
                clients.push(chatClients[socketIds[i]]);
            }
        }
    }

    return clients;
}

最佳答案

此代码解决的问题

function getClientsInRoom(socketId, room) {
    // get array of socket ids in this room
    var socketIds = io.sockets.adapter.rooms[room];
    var clients = [];

    if (socketIds && socketIds.length > 0) {
        //socketsCount = socketIds.lenght;

        // push every client to the result array
        for (var i = 0, len = socketIds.length; i < len; i++) {
            // check if the socket is not the requesting
            // socket
            if (socketIds.sockets[i] != socketId) {
                clients.push(chatClients[Object.keys(socketIds.sockets)[i]]);
            }
        }
    }

    return clients;
}
