Obtaining Client IP Address
Terakhir diperbarui: 2025-06-18 16:29:56
Since the front end cannot directly obtain the client IP address, it's often necessary to obtain the client IP address through the server side or third-party services in multiple business scenarios. This example gets the client IP through the Request object's eo.clientIp property, and assembled into data in the form of JSON to respond to the clients, which succeeds in obtaining client IP address by the use of edge function. 
function handleRequest(request) {
  // Obtain the client IP through the request.eo.clientIp
  const ip = request.eo.clientIp || '';
  
  // Respond with JSON data
  return new Response(JSON.stringify({ ip }), {
    headers: { 'content-type': 'application/json' },
  });
}

addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request));
});
