<code>socket.disconnect()</code> can be used only on the client side, not on the server side.

<code>Client.emit('disconnect')</code> triggers the disconnection event on the server, but does not effectively disconnect the client. The client is not aware of the disconnection.

So the question remain : how to force a client to disconnect from server side ?

Any reason why you can't have the server emit a message to the client that makes it call the disconnect function?

On client:

<pre><code>socket.emit('forceDisconnect');
</code></pre>

On Server:

<pre><code>socket.on('forceDisconnect', function(){
 socket.disconnect();
});
</code></pre>

For those who found this on google - there is a solution for this right now:

Assuming your socket's named socket, use:

You can do <code>socket = undefined</code> in erase which socket you have connected. So when want to connected do socket(url)

So it will look like this

<pre><code>const socketClient = require('socket.io-client');

let socket;

// Connect to server
socket = socketClient(url)

// When want to disconnect
socket = undefined;
</code></pre>

Add new socket connections to an array and then when you want to close all - loop through them and disconnect. (server side)

<pre><code>var socketlist = [];

 io.sockets.on('connection', function (socket) {
 socketlist.push(socket); 
 //...other code for connection here..
 });


 //close remote sockets
 socketlist.forEach(function(socket) { 
 socket.disconnect(); 
 }); 
</code></pre>

Is there any way to disconnect a client with SocketIO, and literally close the connection? So if someone is connected to my server, and I want to close the connection between them and my server, how would I go about doing that?

force client disconnect from server with socket.io and nodejs

React Native

服务器

有没有办法断开客户端与SocketIO的连接，然后真正地关闭连接？所以，如果有人连接到我的服务器，而我想要关闭他们和我的服务器之间的连接，我该怎么做呢？
