在套接字连接上发送附加数据 [英] Send additional data on socket connection

问题描述

如何在套接字连接时最好地发送附加数据?

How to best send additional data upon socket connection?

客户:

socket.on('connect',function(){ 
//I'd like set some values and pass them up to the node server.
});

Node.js 服务器:

Node.js Server:

io.on('connection', function(client){
//I'd like to get the data here.
});

例如发送用户名或电子邮件地址等

For example sending a user name or email address etc.

推荐答案

您应该在连接或创建时发送数据:

You should send your data either in connect or on create:

var s = io('http://216.157.91.131:8080/', { query: "foo=bar" });
s.connect();

var c = io.connect('http://216.157.91.131:8080/', { query: "foo=bar" });

随着 socket.io 的新版本，在服务器上事情已经改变了:

With the new version of socket.io, on server is where the things have been changed:

var io = require('socket.io')(server);

io.use(function(socket, next) {
  var handshakeData = socket.request;
  console.log("middleware:", handshakeData._query['foo']);
  next();
});
