Retrieve Custom Header from Rest request

,

How will we be able to retrieve custom header fields from REST POST WEBSERVICE request.
getTransportInfo is able to retrieve only some specific predefined fields.Is it not possible to retrieve custom header field in webmethod?

Hi,

please add a pub.flow:savePipelineToFile and pub.flow:restorePipelineFromFile after the getTransportInfo invocation.
Use the same Filename as Input for both Services.
This will not harm your normal processing (except for a very small delay), but gives the possibility for debugging.

After the service has been invoked the first time after the change with real data, disable the savePipelineToFile and open the service for debugging and step throuh it.
After the restorePipelineFromFile check what is really in the returned pipeline. There might be undeclared Fields which can be used when explicitly added manually and mapped afterwards.

Please share some screenshots of the above outcome if possible.

Holger

Thanks holger. Yes, i am receiving custom value in runtime and able to use the same.
Previously, i was using the Pipeline debug property in the property view to debug the pipeline. In that case, it was never showing the runtime custom fields.
Once i used the save/restorePipelineToFile to debug, it started showing the runtime custom values.
Thanks a lot for your suggestion.

I am glad to hear that my suggestions was helpful.

Remember to remove the 2 pipeline handling services after finishing the development to save performance.

Hello Moninca,

The header listed in the below URL are from HTTP specification.

http://www.restpatterns.org/

HTTP protocol also supports Custom headers, that always depends on the API design.

Thanks Srikanth.

In our scenario we have rest post service which is exposed to external application.
When they post a request they have some custom headers added to http request header.
We need to filter on headers and pass on the custom header fields to other component.
Is there a way to filter out generic and custom headers without knowing what custom header fields they are sending.

Regards,
Monica
