Client IP address availability? #29

Thanks for a great library

I cant seem to find the following anywhere.

I am using the Teensy41_Server.ino websocket server is it possible to have a method to get the websocket client's IP address please? Or is there any other way to do so?

Eg client.remoteIP() ?

This is useful for IP filtering etc.

Many thanks Marios

Thanks for your interest in and nice words about the library.

Currently, this library as well as its twin WebSockets_Generic Library, designed specifically for resource constraint MCUs, don't have that function to help in eliminating spams, attacks, etc using the help of IP filtering.

You can have these options:

  1. Use the Nodejs, etc. ws(s) server. Then the client IP is easily accessible. or example ws._socket.remoteAddress, ws._socket.remotePort
wss.on('connection', (ws, req) => 
{
    console.log(req.socket.remoteAddress);
});
  1. Write extra code, based on (Native)Ethernet / WiFi, etc to capture the client IP.
  2. Ask for enhancement (for ESP32/ESP8266) on ArduinoWebsockets Library, on which this library is based on.

I'm sorry I currently have no time to work on this issue and closing it now. If there are many more similar requests,I'll possibly reopen and work on the issue.

Good Luck,
