Request Modification

Set Body Policy

The Set Body policy allows you to set or override the incoming request body. GET or HEAD requests do not support bodies on Zuplo, so be sure to use the Change Method policy to update the method to a POST or whatever is appropriate. You might also need to use the Set Header policy to set a content-type.

Configuration

The configuration shows how to configure the policy in the 'policies.json' document.

config/policies.json
{ "name": "my-set-body-inbound-policy", "policyType": "set-body-inbound", "handler": { "export": "SetBodyInboundPolicy", "module": "$import(@zuplo/runtime)", "options": { "body": "Hello World!" } } }

Policy Configuration

  • name <string> - The name of your policy instance. This is used as a reference in your routes.
  • policyType <string> - The identifier of the policy. This is used by the Zuplo UI. Value should be set-body-inbound.
  • handler.export <string> - The name of the exported type. Value should be SetBodyInboundPolicy.
  • handler.module <string> - The module containing the policy. Value should be $import(@zuplo/runtime).
  • handler.options <object> - The options for this policy. See Policy Options below.

Policy Options
