I had some success doing the intercept at the next level above the auth proxy location like this: (using grpc_intercept_errors)
server { listen 443 ssl http2; include grpc_servers.conf; # send all requests to the `/validate` endpoint for authorization auth_request /validate; grpc_intercept_errors on; error_page 401 @grpc_auth_fail; location = /validate { proxy_pass http://auth:5000; #proxy_intercept_errors on; #error_page 401 @grpc_auth_fail; } location @grpc_auth_fail { add_trailer grpc-status 16 always; add_header grpc-status 16 always; add_trailer grpc-message Unauthorized always; add_header grpc-message Unauthorized always; return 200; } } Posted at Nginx Forum: https://forum.nginx.org/read.php?2,284718,284880#msg-284880 _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
