EO-Client-IP activated in the rule engine, 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. addEventListener('fetch', event => {event.respondWith(handleRequest(event.request));});function handleRequest(request) {// Obtain the client IP through the EO-Client-IP headerconst ip = request.headers.get('EO-Client-IP') || '';// Respond with JSON datareturn new Response(JSON.stringify({ ip }), {headers: { 'content-type': 'application/json' },});}
