Estoy tratando de crear un trabajador de Cloudflare que redirige los dominios en función de algunas direcciones de comodín de entrada.
Por ejemplo, digamos que la entrada es esta:
const inputs = [ { "from": "*.example.com/products/3268-shirts*", "to": "https://store.primarydomain.example.com/collections/3268-shirts*" } ]Basado en esto, lo siguiente debería funcionar:
[ { "input": "https://store.domain1.example.com/collections/3222-shirts", "output": "https://store.primarydomain.example.com/collections/3222-shirts" }, { "input": "https://store.domain2.example.com/collections/3222-shirt", "output": "https://store.primarydomain.example.com/collections/3222-shirts" }, { "input": "https://store.domain2.example.com/collections/3222-shirts/site4", "output": "https://store.primarydomain.example.com/collections/3222-shirts/site4" }, { "input": "https://store.domain2.example.com/collections/3222-shirts/?pf_t_site=the_site", "output": "https://store.primarydomain.example.com/collections/3222-shirts/?pf_t_site=site_site" }, { "input": "https://store.domain2.example.com/collections/3222-shirts/products/9000-pants?variant=2995454033242234&utm_content=171134", "output": "https://store.primarydomain.example.com/collections/3222-shirts/products/9000-pants?variant=2995454033242234&utm_content=171134" } ]La entrada sería el dominio solicitado y la salida es el dominio al que se redirigirá.
Esto es lo que tengo hasta ahora para esto, que está cerca. Redirecciona, pero no para este caso específico, y no con los dominios correctos.
const inputs = [ { "from": "https://store.domain2.example.com/collections/*", "to": "https://store.example.com/collections/*" } ] async function handleRequest(request) { const {url} = request; const location = redirects.reduce((loc, r) => { let match = url.split(r.from.replace("*", ""))[1]; let final = r.to.replace("*", "") + match; if (match) return final; }, ""); if (location) { console.log(`${url} redirects to ${location}`) return Response.redirect(location, 301) } return fetch(request) } addEventListener("fetch", async event => { event.respondWith(handleRequest(event.request)) })¿Cómo puedo cambiar el código anterior para que funcionen las URL de prueba?
Lo siguiente debería ser capaz de ponerte en marcha. Tenga en cuenta que handleRequest() coincidirá con el PRIMER redirect.from. Por lo tanto, coloque los más específicos en la parte superior si el destino debe ser diferente.
var redirects = [ { "from": "oldstore1.example.com", // target a specific sub-domain. Notice, this is before the match all sub-domains of example.com "to": "oldstore1.primarydomain.example.com" }, { "from": ".example.com", // will match any/all sub-domains "to": "primarydomain.example.com" } ] // This will match on the first matching redirects.from. function handleRequest(request) { let visitorDomain = new URL(request.url); const location = redirects.find((loc, r) => visitorDomain.hostname.endsWith(loc.from)); // matches on the ending of URL.hostname. // check if either no suitable location was matched // OR if the destination matches the current URL, if so, do not perform 301 if(!location || visitorDomain.hostname === location.to) { console.log('Not going to perform 301'); return //fetch(request); } // A redirect will happen const redirectDest = visitorDomain.protocol + '//' + location.to + visitorDomain.pathname + visitorDomain.search; console.log('redirecting to', redirectDest); //return Response.redirect(location, 301) }Algunos ejemplos
handleRequest({url: 'https://store.domain2.example.com/collections/3222-shirts'}); // redirects to: https://primarydomain.example.com/collections/3222-shirts handleRequest({url: 'https://www.somewhere.oldstore1.example.com/collections/3222-shirts'}); // redirects to: https://oldstore1.primarydomain.example.com/collections/3222-shirts handleRequest({url: 'https://store.domain2.example.com/collections/3222-shirts/products/9000-pants?variant=2995454033242234&utm_content=171134'}); // redirects to: https://primarydomain.example.com/collections/3222-shirts/products/9000-pants?variant=2995454033242234&utm_content=171134 handleRequest({url: 'https://store.domain2.example.com/collections/3222-shirts/products/9000-pants'}); // redirects to: https://primarydomain.example.com/collections/3222-shirts/products/9000-pants?variant=2995454033242234&utm_content=171134 handleRequest({url: 'https://primarydomain.example.com/collections/3222-shirts/products/9000-pants'}); // NOT going to Redirect. Already at a suitable matching subdomain.domain.
