Advanced API Gateway: Requests Size

The API Gateway uses the default NGINX value of 1MiB.

Definition

The request size is the maximum value of the payload body size associated with the request.

If a body exceeds the client_max_body_size value, a 413 Request Entity Too Large response will be sent to the client.

Change the default size​

Through the advanced section of the API Gateway is possible to change the default size allowed by client requests.

For example the directive

client_max_body_size 10m;

will allow for any request to have a request body up until a size of 10 MiB.

tip

If you put 0 as value, then any size of body request will be accepted.

How can you change the default size for all the request?​

  1. Go to Section: api-gateway/request-size.conf

  2. To change the value just enter the following string and choose the value you want to set:

client_max_body_size 10m;

How can you change only the Backoffice request size?​

  1. Go to Section: api-gateway/backoffice-root-location-extension.conf

  2. To change the value just enter the following string and choose the value you want to set:

client_max_body_size 16k;

In this case you'll change the maximum request size to 16KiB only for the endpoints of the Backoffice Application.

How can you change only the request size of a specific root?​

  1. Go to Section: api-gateway/root-location-extension.conf

  2. Here you fill find an empty file. To change the value just enter the following string and choose the value you want to set:

location ~ "^/example" {
  client_max_body_size 1m;

  proxy_pass http://$proxy_name$proxy_url;
}

In this case you'll change the request size only for the locations that starts with the path /example.

caution

Since the proxy_pass variable is not inherited inside the location block, you must define it again.

In case of a change in proxy_name or proxy_url variables names this configuration will not work.
