Remote Authentication

In order to avoid customers' resources being accessed by illegal users, this example transmits the request to the customer-specified remote authentication server. The authentication server verifies the user's request, and the Edge functions decide whether to allow access to the target resources based on the check result returned by the remote authentication server. If the authentication fails, the client will be responded with a 403 status code.
async function handleRequest(request) {
// Remote authentication API address
const checkAuthUrl = 'https://www.example.com/';
// Initiate remote authentication
const checkAuthRes = await fetch(checkAuthUrl);

// Authentication passed, normal access to resources
if (checkAuthRes.status === 200) {
return fetch(request, {
headers: request.headers,
});
}
// Authentication failed, prohibit access to resources
return new Response(null, {
status: 403
});
}

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