You have to create a room with conversation_id and make users to subscribe to that room, so that you can emit a private message to that room it by,

您必须使用conversation_id创建一个房间并让用户订阅该房间，以便您可以向该房间发出私人消息，

client

客户

var socket = io.connect('http://ip:port');

socket.emit('subscribe', conversation_id);

socket.emit('send message', {
    room: conversation_id,
    message: "Some message"
});

socket.on('conversation private post', function(data) {
    //display data.message
});

Server

服务器

socket.on('subscribe', function(room) {
    console.log('joining room', room);
    socket.join(room);
});

socket.on('send message', function(data) {
    console.log('sending room post', data.room);
    socket.broadcast.to(data.room).emit('conversation private post', {
        message: data.message
    });
});

Here is the docs and example for creating a room, subscribing to the room and Emit message to a room:

SURE: Simply,

当然：简单地说，

This is what you need :

这就是你需要的：

 io.to(socket.id).emit("event", data);

whenever a user joined to the server,socket details will be generated including ID.This is the ID really helps to send a message to particular people.

每当用户加入服务器时，将生成包括ID的套接字详细信息。这是真正有助于向特定人员发送消息的ID。

first we need to store all the socket.ids in array,

首先我们需要将所有socket.id存储在数组中，

   var people={};

   people[name] =  socket.id;

here name is the reciever name. Example:

这里的名字是收件人姓名。例：

  people["ccccc"]=2387423cjhgfwerwer23;

So, now we can get that socket.id with the reciever name whenever we are sending message:

所以，现在我们可以在发送消息时使用接收者名称获取socket.id：

for this we need to know the recievername.You need to emit reciever name to the server.

为此我们需要知道recievername.You需要向服务器发出接收者名称。

final thing is:

最后一件事是：

  socket.on('chat message', function(data){
 io.to(people[data.reciever]).emit('chat message', data.msg);
 });

Hope this works well for you.!!Good Luck

希望这对你有用。!!祝你好运
