生成socket ID时用自定义名称修改socket.name

Question

我只是想将自定义数据从客户端发送到服务器，而不添加更多请求。

我正在阅读线程：socket.io socket.set and socket.get - what is the callback argument for? 并说：The get and set functions on the socket object were removed in version 1.x.

我正在使用一个非常简单的 node/express 应用程序，下一个代码：

var io = require('socket.io').listen(http);
io.on('connection', function(socket){
    console.log('a user connected: ' + socket.id);
    socket.on('disconnect', function(){
        console.log( socket.name + ' has disconnected from the chat.' + socket.id);
    });
});

是否存在一种在初始化套接字时在属性 socket.name 中设置自定义值的方法？

Answer 1

此解决方案仅适用于您不需要在集群中或运行在其他服务器中的应用程序。

var clients = {};

io.on('connection', function(socket){
    console.log('a user connected: ' + socket.id);

    clients[socket.id] = {name: 'Your name'};

    socket.on('disconnect', function(){
        console.log( clients[socket.id].name + ' has disconnected from the chat.' + socket.id);
        delete clients[socket.id]; //Delete client
    });
});

之后，您可以通过以下方式找到相关数据：

clients[socket.id];
