# Swagger NetworkError

Swaggerでheaderを付与したリクエストで発生

nginx側で`Access-Control-Allow-Headers`にリクエストするヘッダーkeyを追加して解決

```
    if ($cros = 'true') {
          add_header 'swagger' '2.0' always;
          #add_header 'Access-Control-Allow-Origin' '*' always;
          add_header 'Access-Control-Allow-Origin' "$http_origin" always;
          add_header 'Access-Control-Allow-Credentials' 'true' always;
          add_header Access-Control-Allow-Methods 'GET, POST, PUT, DELETE, OPTIONS';
          add_header Access-Control-Allow-Headers 'Origin, Authorization, Accept, Content-Type, HOGE-KEY';
          add_header 'Access-Control-Expose-Headers' 'Authorization' always;
        }

        if ($option_method = 'true') {
          #add_header Access-Control-Allow-Origin '*';
          add_header Access-Control-Allow-Methods 'GET, POST, PUT, DELETE, OPTIONS';
          add_header 'Access-Control-Allow-Origin' "$http_origin" always;
          add_header 'Access-Control-Allow-Credentials' 'true' always;
          add_header Access-Control-Allow-Headers 'Origin, Authorization, Accept, Content-Type, HOGE-KEY';
          add_header Access-Control-Max-Age 3600;
          add_header 'Access-Control-Expose-Headers' 'Authorization' always;
          add_header Content-Type 'text/plain charset=UTF-8';
          add_header Content-Length 0;

          return 204;
        }

```
