Parameters

Here's a list of all the parameters which can be used in this plugin's configuration:

• name or plugin

  string required

  The name of the plugin, in this case jq.

  • If using the Kong Admin API, Konnect API, declarative configuration, or decK files, the field is name.
  • If using the KongPlugin object in Kubernetes, the field is plugin.

• service.name or service.id

  string

  The name or ID of the service the plugin targets. Set one of these parameters if adding the plugin to a service through the top-level /plugins endpoint. Not required if using /services/{serviceName|Id}/plugins.

• route.name or route.id

  string

  The name or ID of the route the plugin targets. Set one of these parameters if adding the plugin to a route through the top-level /plugins endpoint. Not required if using /routes/{routeName|Id}/plugins.

• consumer.name or consumer.id

  string

  The name or ID of the consumer the plugin targets. Set one of these parameters if adding the plugin to a consumer through the top-level /plugins endpoint. Not required if using /consumers/{consumerName|Id}/plugins.

• enabled

  boolean default: true

  Whether this plugin will be applied.

• config

  record required
  • request_jq_program

    string

    The jq program to run on the request body. For example, .[0] | { "X-Foo": .foo }. Either request_jq_program or response_jq_plugin must be included in the configuration.

  • request_jq_program_options

    record

    Boolean option flags to modify the run behavior of the jq program run on the request body.

    • compact_output: Returns output in a compact form without additional spacing, and with each JSON object on a single line. Defaults to true. Set to false for ‘pretty’ output.
    • raw_output: Outputs as raw strings, not JSON quoted. Default is false.
    • join_output: Similar to raw_output but does not output newline separators. Default is false.
    • ascii_output: jq usually outputs non-ASCII Unicode codepoints as UTF-8, even if the input specified them as escape sequences (like μ). Using this option, you can force jq to produce pure ASCII output, replacing every non-ASCII character with the equivalent escape sequence. Default is false.
    • sort_keys: Outputs the fields of each object with the keys in sorted order. Default is false.

    • compact_output

      boolean required default: true

    • raw_output

      boolean required default: false

    • join_output

      boolean required default: false

    • ascii_output

      boolean required default: false

    • sort_keys

      boolean required default: false

  • request_if_media_type

    array of type string default: application/json

    A list of media type strings. The media type included in the Content-Type request header must match one of the media types on this list for the program to run.

  • response_jq_program

    string

    The jq program to run on the response body. For example, .[0] | { "X-Foo": .foo }. Either request_jq_program or response_jq_plugin must be included in configuration.

  • response_jq_program_options

    record

    Boolean option flags to modify the run behavior of the jq program run on the response body.

    • compact_output: Returns output in a compact form without additional spacing, and with each JSON object on a single line. Defaults to true. Set to false for ‘pretty’ output.

  • response_if_status_code

    array of type integer default: 200

    A list of HTTP response status codes. The response status code must match one of the response status codes on this list for the program to run.
