Kubernetes users: Version v1beta1 of the Ingress specification does not allow the use of named regex capture groups in paths. If you use the ingress controller, you should use unnamed groups, e.g. (\w+)/instead of (?<user_id>\w+). You can access these based on their order in the URL path. For example $(uri_captures[1]) obtains the value of the first capture group.

In the following examples, the plugin is enabled on a service. This would work similarly for routes.

Examples: Passing multiple headers in one request

Pass each header separately

Add multiple headers by passing each header:value pair separately:

curl -X POST http://localhost:8001/services/example-service/plugins \
  --data "name=request-transformer" \
  --data "config.add.headers[1]=h1:v1" \
  --data "config.add.headers[2]=h2:v1"

plugins:
- name: request-transformer
  config:
    add:
      headers: ["h1:v1", "h2:v1"]

Comma-separated header:value pairs

Add multiple headers by passing comma-separated header:value pair (only possible with a database):

curl -X POST http://localhost:8001/services/example-service/plugins \
  --data "name=request-transformer" \
  --data "config.add.headers=h1:v1,h2:v1"

Config as JSON body

Add multiple headers by passing config as a JSON body (only possible with a database):

curl -X POST http://localhost:8001/services/example-service/plugins \
  --header 'content-type: application/json' \
  --data '{"name": "request-transformer", "config": {"add": {"headers": ["h1:v1", "h2:v1"]}}}'

Example: Adding a querystring and a header

curl -X POST http://localhost:8001/services/example-service/plugins \
  --data "name=request-transformer" \
  --data "config.add.querystring=q1:v2,q2:v1" \
  --data "config.add.headers=h1:v1"

plugins:
- name: request-transformer
  config:
    add:
      headers: ["h1:v1"],
      querystring: ["q1:v1", "q2:v2"]

Example: Appending and removing in one request

Append multiple headers and remove a body parameter:

curl -X POST http://localhost:8001/services/example-service/plugins \
  --header 'content-type: application/json' \
  --data '{"name": "request-transformer", "config": {"append": {"headers": ["h1:v2", "h2:v1"]}, "remove": {"body": ["p1"]}}}'

plugins:
- name: request-transformer
  config:
    add:
      headers: ["h1:v1", "h2:v1"]
    remove:
      body: [ "p1" ]
