Come descritto in Aggiunta del supporto CORS a ESP, puoi configurare il proxy di servizio estendibile (ESP) per supportare CORS.
Se le opzioni ESP non forniscono il supporto CORS richiesto dalla tua applicazione, puoi aggiungere le opzioni CORS al file di configurazione di ESP,nginx.conf.
Aggiunta delle opzioni CORS a nginx.conf
Per aggiungere le opzioni CORS:
Inizia con un file nginx.conf contenente la configurazione richiesta da Cloud Endpoints. Puoi iniziare con il nginx.conf di esempio oppure, se hai già implementato ESP, puoi connetterti tramite SSH al contenitore ESP e copiare il file nginx.conf dalla directory /etc/nginx/endpoints/.
Aggiungi le opzioni CORS richieste dalla tua applicazione a nginx.conf. Puoi
utilizzare l'esempio CORS su NGINX come punto di partenza.
Avvia ESP con l'opzione --nginx_config e il percorso del file personalizzatonginx.conf.

Start with a `nginx.conf` file that contains the configuration required by\n Cloud Endpoints. You can start with the [sample\n `nginx.conf`](https://github.com/GoogleCloudPlatform/endpoints-samples/blob/master/k8s/nginx.conf),\n or if you have already deployed ESP, you can SSH to the ESP container and\n copy the `nginx.conf` file from the `/etc/nginx/endpoints/` directory.\n\n2. Add the CORS options that your application requires to `nginx.conf`. You can\n use the [CORS on NGINX](https://enable-cors.org/server_nginx.html) example\n as a starting point.\n\n3. Start ESP with the `--nginx_config` option with the path to the custom\n `nginx.conf` file.\n\nWhat's next\n-----------\n\n- Learn about [ESP's startup options](/endpoints/docs/grpc/specify-proxy-startup-options).\n\n- Learn how to [SSH to ESP's container on GKE](/endpoints/docs/grpc/troubleshoot-gke-deployment#checking_configuration_files).\n\n- Learn about [using a custom nginx.conf on GKE](/endpoints/docs/grpc/custom-nginx)."]]
