POST Request Headers for REST Service Pega 7.1.7 not Available/Overrided?
Hi,
My Application is an headless application, so have UI built on other technologies and built REST service in Pega to start the automated bussiness process. I have a Service REST for processing request from UI.
Request Header for all service calls from UI are having below information. Requirement is to capture all client header informtion, however all those headers are getting overrided when parsing the request in Pega.
From UI:
Host:"XXX.XX.XX.XX"
User-Agent:"Mozilla/5.0 ..."
Accept:"*/*"
Accept-Language:"en-GB,en;q=0.5"
Accept-Encoding:"gzip, deflate"
Referer:"http://XXX.XX.XX.XX/XXXXXXXXXXX&SOURCE=aaaaP&TID=aaaa&c=e"
Content-Type:"application/json"
X-Requested-With:"XMLHttpRequest"
Content-Length:"XXXX"
In Pega:
Mapped all required headers in REST Service >> Methods >> POST request headers. And all headers are getting overided in Pega and few are not available.
ex: host is being replaced by Pega host name and user-agent is being replaced by somthing else.
Pega: 7.1.7
Rest Service with basic authentication
Service Package: Stateless
Does anyone faced this issue?

If you change to custom auth, you can grab the header values during authentication. These are the only time they are available. @java("((javax.servlet.http.HttpServletRequest)tools.getRequestor().getRequestorPage().getObject(\"pxHTTPServletRequest\")).getHeader(\"x-forwarded\")") If you want to output to the logfile all the HTTP headers you are getting in the incoming request for debug purposes use the following in a Java step: javax.servlet.http.HttpServletRequest request = //debug Remember to comment this JAVA step or comment the debug code after you are done with it. |

Where are you seeing the values being changed? Can you log the values as they're mapped to confirm that takes place?
It sounds like the response mapping may be getting in the way.
This is currently being handled through SR-B65815.

"host is being replaced by Pega host name"
The Host header is the destination host. It must be set by all HTTP clients, and the Pega server is hosting the service, so this would be the expected value sent by a client that was calling the service on Pega. The client that is making the connection to the Service sets this, not Pega.
What are you trying to capture from the Host header?
"user-agent is being replaced by something else"
The User-Agent header is being set by the client and Pega would not be changing this. Perhaps the request is going through some HTTP proxy which issues the request on the client's behalf, and the User-Agent header would then be that of the "real" client?
