[Serusers] RV: [Serdev] Parse Referred-By

[Ing. Francisco Talavera]

Andy:

I was write a module "MyModule" in SER, It communicates with other program
(MyProgram) via Socket. This Module (MyModule) need to send the Referred-By
header field to MyProgram. That’s my problem.

The communication between MyModule and MyProgram is XML message, I need to
parse the Referred header field and encapsulate in XML message.

I now SER have a function "parse_headers()", with this function I parse the
call-id header field... like this.. parse_headers(msg, (int) HDR_CALLID, 0)

But I can NOT do this ... parse_headers(msg, (int) HDR_REFERRED_BY, 0)...
because HDR_REFERRED_BY doesn’t exist..

Now I think it was more clearly.

Thank in advance
Francisco Talavera

You only need to parse the header field if you want to load parts of it 
into avp or use them in other code parts of SER. In newer versions of 
SER (don't know exactly from which version upwards) you can also load 
the content of the header into avp using the avpops module.

If you just want to pass it to a script called by exec_dset() or 
exec_msg(), you can access any header field using the environment 
variable SIP_HF_<header-name>.

So I'm not sure if it's really needed to touch the parser unless you 
tell us how exactly you plan to use it.
