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/httpbin/plugins \
  --data "name=request-transformer-advanced" \
  --data "config.add.headers[1]=h1:v1" \
  --data "config.add.headers[2]=h2:v1"
Incoming Request Headers Upstream Proxied Headers
h1: v1 h1: v1, h2: v1

Comma-separated header:value pairs

Add multiple headers by passing comma separated header:value pair:

curl -X POST http://localhost:8001/services/httpbin/plugins \
  --data "name=request-transformer-advanced" \
  --data "config.add.headers=h1:v1,h2:v2"
Incoming Request Headers Upstream Proxied Headers
h1: v1 h1: v1, h2: v1

Config as JSON body

Add multiple headers passing config as a JSON body:

curl -X POST http://localhost:8001/services/httpbin/plugins \
  --header 'content-type: application/json' \
  --data '{"name": "request-transformer-advanced", "config": {"add": {"headers": ["h1:v2", "h2:v1"]}}}'
Incoming Request Headers Upstream Proxied Headers
h1: v1 h1: v1, h2: v1

Multiple headers and query strings

Add multiple headers and query string parameters if not already set:

curl -X POST http://localhost:8001/services/httpbin/plugins \
  --data "name=request-transformer-advanced" \
  --data "config.add.headers=h1:v1,h2:v1" \
  --data "config.add.querystring=q1:v2,q2:v1" \
Incoming Request Headers Upstream Proxied Headers
h1: v1 h1: v1, h2: v1
h3: v1 h1: v1, h2: v1, h3: v1
Incoming Request Query String Upstream Proxied Query String
?q1=v1 ?q1=v1&q2=v1
  ?q1=v2&q2=v1

Example: Adding a querystring and a header

curl -X POST http://localhost:8001/services/httpbin/plugins \
  --data "name=request-transformer-advanced" \
  --data "config.add.querystring=q1:v2,q2=v1" \
  --data "config.add.headers=h1:v1"
Incoming Request Headers Upstream Proxied Headers
h1: v1 h1: v1, h2: v1
h3: v1 h1: v1, h2: v1, h3: v1
Incoming Request Query String Upstream Proxied Query String
?q1=v1 ?q1=v1&q2=v1
  ?q1=v2&q2=v1

Example: Appending and removing in one request

Append multiple headers and remove a body parameter:

curl -X POST http://localhost:8001/services/httpbin/plugins \
  --data "name=request-transformer-advanced" \
  --data "config.append.headers=h1:v2,h2:v1" \
  --data "config.remove.body=p1" \
Incoming Request Headers Upstream Proxied Headers
h1: v1 h1: v1, v2, h2: v1
Incoming URL Encoded Body Upstream Proxied URL Encoded Body
p1=v1&p2=v1 p2=v1
p2=v1 p2=v1
