I have a stream like below I am trying to make a http rest Post request and log it to the logger.I have a API-Key header for which I used this below header enricher module
https://github.com/spring-projects/spring-xd-modules/tree/master/header-enricher
stream create --name test24 --definition "http |header-enricher --headers={\"Api-Key\":\"'xyz'\"}| http-client --url='''http://xyz:/abc''' --httpMethod=POST | log " --deploy
http post --data '{"profileReferenceID":"pPPpe85Ht91e%2FpCvlkJMkniwiM%2BGvPjATkjc6HGqaJFS065txVj%2BhqDPsHz54KEm1RrCXftjNCSl2fpBKKKdrie9n6t9jetWhk29ELCmbw0%3D","templateURL":{"type":"type","href":"/content/notification/templates/EOSWEL?firstName=Abcd&userName=dddd&accountLast=2144&phone=1234&SvcgLOBCd=MS","method":"POST"}}'

I am getting 403 forbidden i get this error from my webservice if my client api key is not passed which i was able to reproduce in post man .So I assume my API-Key header is not passed.

Answer 1

You should add your Api-Key header to be mapped to the HTTP request header:
http-client --url='''http://xyz:/abc''' --httpMethod=POST --mappedRequestHeaders=HTTP_REQUEST_HEADERS,Api-Key
mappedRequestHeaders
request message header names to be propagated to/from the adpater/gateway (String, default: HTTP_REQUEST_HEADERS)
Where HTTP_REQUEST_HEADERS is a set of only standard HTTP headers which are appropriate for request.
