socket.io将消息从一个命名空间发送到另一个命名空间

我正在尝试将消息从一个命名空间发送到另一个命名空间（在连接上）。 下面是一些示例代码，说明了我是如何尝试实现它的

[服务器]

// Namespaces
var users_ns = io.of('/users');
var machines_ns = io.of('/machines');

// Attempt to receive the event on the socket
users_ns.on('connection', function(socket){
    socket.on('test', function(socket){
        console.log('socket test');
    });
});

// Attempt to receive the event on the namespace
users_ns.on('test', function(socket){
    console.log('namespace test');
});

// Emit an event to the 'users' namespace
machines_ns.on('connection', function(socket){
    users_ns.emit('test');
});

var socket = io('http://localhost/users');

var socket = io('http://localhost/machines');

// Namespaces
var users_ns = io.of('/users');
var machines_ns = io.of('/machines');

// Attempt to receive the event on the socket
users_ns.on('connection', function(socket){
    socket.on('test', function(){
        console.log('socket test');
    });
});


// Emit an event to the 'users' namespace
machines_ns.on('connection', function(socket){
    users_ns.emit('test');
});

var socket = io('http://localhost/users');
socket.on('test',function(){ alert('broadcast received');});

var socket = io('http://localhost/machines');

[Client1]

// Namespaces
var users_ns = io.of('/users');
var machines_ns = io.of('/machines');

// Attempt to receive the event on the socket
users_ns.on('connection', function(socket){
    socket.on('test', function(socket){
        console.log('socket test');
    });
});

// Attempt to receive the event on the namespace
users_ns.on('test', function(socket){
    console.log('namespace test');
});

// Emit an event to the 'users' namespace
machines_ns.on('connection', function(socket){
    users_ns.emit('test');
});

var socket = io('http://localhost/users');

var socket = io('http://localhost/machines');

// Namespaces
var users_ns = io.of('/users');
var machines_ns = io.of('/machines');

// Attempt to receive the event on the socket
users_ns.on('connection', function(socket){
    socket.on('test', function(){
        console.log('socket test');
    });
});


// Emit an event to the 'users' namespace
machines_ns.on('connection', function(socket){
    users_ns.emit('test');
});

var socket = io('http://localhost/users');
socket.on('test',function(){ alert('broadcast received');});

var socket = io('http://localhost/machines');

[Client2]

// Namespaces
var users_ns = io.of('/users');
var machines_ns = io.of('/machines');

// Attempt to receive the event on the socket
users_ns.on('connection', function(socket){
    socket.on('test', function(socket){
        console.log('socket test');
    });
});

// Attempt to receive the event on the namespace
users_ns.on('test', function(socket){
    console.log('namespace test');
});

// Emit an event to the 'users' namespace
machines_ns.on('connection', function(socket){
    users_ns.emit('test');
});

var socket = io('http://localhost/users');

var socket = io('http://localhost/machines');

// Namespaces
var users_ns = io.of('/users');
var machines_ns = io.of('/machines');

// Attempt to receive the event on the socket
users_ns.on('connection', function(socket){
    socket.on('test', function(){
        console.log('socket test');
    });
});


// Emit an event to the 'users' namespace
machines_ns.on('connection', function(socket){
    users_ns.emit('test');
});

var socket = io('http://localhost/users');
socket.on('test',function(){ alert('broadcast received');});

var socket = io('http://localhost/machines');

你知道为什么这不起作用吗？

你的服务器代码是正确的，但是发生了一些误解

[服务器]

// Namespaces
var users_ns = io.of('/users');
var machines_ns = io.of('/machines');

// Attempt to receive the event on the socket
users_ns.on('connection', function(socket){
    socket.on('test', function(socket){
        console.log('socket test');
    });
});

// Attempt to receive the event on the namespace
users_ns.on('test', function(socket){
    console.log('namespace test');
});

// Emit an event to the 'users' namespace
machines_ns.on('connection', function(socket){
    users_ns.emit('test');
});

var socket = io('http://localhost/users');

var socket = io('http://localhost/machines');

// Namespaces
var users_ns = io.of('/users');
var machines_ns = io.of('/machines');

// Attempt to receive the event on the socket
users_ns.on('connection', function(socket){
    socket.on('test', function(){
        console.log('socket test');
    });
});


// Emit an event to the 'users' namespace
machines_ns.on('connection', function(socket){
    users_ns.emit('test');
});

var socket = io('http://localhost/users');
socket.on('test',function(){ alert('broadcast received');});

var socket = io('http://localhost/machines');

当您向用户广播\u ns套接字时，此事件在客户端接收，而不是在服务器端。所以这是正确的客户端代码

[Client1]

// Namespaces
var users_ns = io.of('/users');
var machines_ns = io.of('/machines');

// Attempt to receive the event on the socket
users_ns.on('connection', function(socket){
    socket.on('test', function(socket){
        console.log('socket test');
    });
});

// Attempt to receive the event on the namespace
users_ns.on('test', function(socket){
    console.log('namespace test');
});

// Emit an event to the 'users' namespace
machines_ns.on('connection', function(socket){
    users_ns.emit('test');
});

var socket = io('http://localhost/users');

var socket = io('http://localhost/machines');

// Namespaces
var users_ns = io.of('/users');
var machines_ns = io.of('/machines');

// Attempt to receive the event on the socket
users_ns.on('connection', function(socket){
    socket.on('test', function(){
        console.log('socket test');
    });
});


// Emit an event to the 'users' namespace
machines_ns.on('connection', function(socket){
    users_ns.emit('test');
});

var socket = io('http://localhost/users');
socket.on('test',function(){ alert('broadcast received');});

var socket = io('http://localhost/machines');

[Client2]

// Namespaces
var users_ns = io.of('/users');
var machines_ns = io.of('/machines');

// Attempt to receive the event on the socket
users_ns.on('connection', function(socket){
    socket.on('test', function(socket){
        console.log('socket test');
    });
});

// Attempt to receive the event on the namespace
users_ns.on('test', function(socket){
    console.log('namespace test');
});

// Emit an event to the 'users' namespace
machines_ns.on('connection', function(socket){
    users_ns.emit('test');
});

var socket = io('http://localhost/users');

var socket = io('http://localhost/machines');

// Namespaces
var users_ns = io.of('/users');
var machines_ns = io.of('/machines');

// Attempt to receive the event on the socket
users_ns.on('connection', function(socket){
    socket.on('test', function(){
        console.log('socket test');
    });
});


// Emit an event to the 'users' namespace
machines_ns.on('connection', function(socket){
    users_ns.emit('test');
});

var socket = io('http://localhost/users');
socket.on('test',function(){ alert('broadcast received');});

var socket = io('http://localhost/machines');

当一个套接字连接到计算机名称空间时，所有连接到用户名称空间的客户端都会发出“广播已接收”警报。

太好了，非常感谢您的回复！这完全有道理。我的困惑是，我认为事件应该先通过其他NS，然后才最终发送到客户端。
