Socket.io自定义客户端ID [英] Socket.io custom client ID

问题描述

我正在使用socket.io创建一个聊天应用，我想使用我的自定义客户端ID，而不是默认值（ 8411473621394412707 ， 1120516437992682114 ）。在连接或仅使用某些内容跟踪每个ID的自定义名称时，是否有任何方法可以发送自定义标识符？谢谢！

I'm making a chat app with socket.io, and I'd like to use my custom client id, instead of the default ones (8411473621394412707, 1120516437992682114). Is there any ways of sending the custom identifier when connecting or just using something to track a custom name for each ID? Thanks!

推荐答案

您可以在服务器上创建一个数组，并在其上存储自定义对象。例如，您可以将Socket.io创建的ID和每个客户端发送的自定义ID存储到服务器：

You can create an array on the server, and store custom objects on it. For example, you could store the id created by Socket.io and a custom ID sent by each client to the server:

var util = require("util"),
    io = require('/socket.io').listen(8080),
    fs = require('fs'),
    os = require('os'),
    url = require('url');

    var clients =[];

    io.sockets.on('connection', function (socket) {

        socket.on('storeClientInfo', function (data) {

            var clientInfo = new Object();
            clientInfo.customId         = data.customId;
            clientInfo.clientId     = socket.id;
            clients.push(clientInfo);
        });

        socket.on('disconnect', function (data) {

            for( var i=0, len=clients.length; i<len; ++i ){
                var c = clients[i];

                if(c.clientId == socket.id){
                    clients.splice(i,1);
                    break;
                }
            }

        });
    });

在此示例中，您需要从每个客户端调用 storeClientInfo 。 / p>

in this example, you need to call storeClientInfo from each client.

<script>
    var socket = io.connect('http://localhost', {port: 8080});

    socket.on('connect', function (data) {
        socket.emit('storeClientInfo', { customId:"000CustomIdHere0000" });
    });
</script>

希望这有帮助。
