socket.io客户端到客户端消息传递 [英] socket.io client to client messaging

问题描述

我无法使用socket.io获取基本客户端到客户端（或真正的客户端 - >服务器 - >客户端）。下面是我现在的代码：

I'm having trouble getting basic client to client (or really client->server->client) working with socket.io. Heres the code I have right now:

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

users.push(socket.sessionId);

for(userID in users)    {
    console.log(userID);
    io.sockets.socket(userID).emit('message', { msg: 'New User Connected succesfully' });
}
socket.emit('message', { msg: 'Connected succesfully' });


socket.on('my other event', function (data) {
    console.log(data);
  });
});

根据我的理解，这应该将新用户消息发送给每个连接的用户（单独，因为我想要以后做实际的个人信息）。相反，我最后只得到连接成功的消息。我的服务器或客户端没有任何错误或其他负面指示。

From my understanding, that should send the new user message to every connected user (individually, since i want to do actual individual messages later). Instead, I only get the 'connected successfully' message at the end. I don't get any errors or other negative indicators from my server or client.

为什么 io.sockets.socket（userID）的任何想法.emit（）无法使用或在其位置使用什么？

Any ideas of why io.sockets.socket(userID).emit() doesn't work or what to use in its place?

推荐答案

尝试

users.push(socket); // without .sessionId

for (var u in users)    {
   // users[u] is now the socket
   console.log(users[u].id);
   users[u].emit('message', { msg: 'New User Connected succesfully' });
}
