Re: [reSIProcate] Does there have a common way to got RFC headers value and extension headers value ?

[Karlsson <boost.regex@xxxxxxxxx>]

Thank you Byron, but as my function, the user call this function and passed the headerName as parameter,

I do not know the header is built-in header or is extension header, so I want to found common way.

 

I just think a stupid idea, use the case to mapping headerName parameter with the buit-in headers.

 

void GetHeaderValue(Data buff, string headerName)

{

 SipMessage * message = SipMessage::make(buff);
 if (!message)
 {
  return ;
 }

 

case h_to:

   compare headerName with "to"

   break

 

case h_from:

    compare headerName with "to"

   break

 

default:

    it's extension header. 

  break

 ExtensionHeader h_Extension(headerName.c_str());
 if (message->exists(h_Extension) == false)
 {
  return ;
 }

 if (message->header(h_Extension).empty() == true)
 {
  return ;
 }

 if (message->header(h_Extension).front().isWellFormed() == false)
 {
  return ;
 }

 Data temp(message->header(h_Extension).front().value());

}

 

But this is not pretty.

       You don't access the headers with built-in support with
ExtensionHeader. You need to use the already-defined header access
tokens. (see http://www.resiprocate.org/Use_Overview#Headers)
