As described in Adding CORS support to
ESP,
you can configure the Extensible Service Proxy
(ESP) to support CORS.
If the ESP options don't provide the CORS support that your
application requires, you can add the CORS options to ESP's configuration file,
nginx.conf.
Adding the CORS options to nginx.conf
To add the CORS options:
Start with a nginx.conf file that contains the configuration required by
Cloud Endpoints. You can start with the sample
nginx.conf,
or if you have already deployed ESP, you can SSH to the ESP container and
copy the nginx.conf file from the /etc/nginx/endpoints/ directory.
Add the CORS options that your application requires to nginx.conf. You can
use the CORS on NGINX example
as a starting point.
Start ESP with the --nginx_config option with the path to the custom
nginx.conf file.
