getOne
Gets the value of header @name in @hdrs.
Use this for headers whose values are not comma-delimited lists, and which therefore can only appear at most once in the headers. For list-valued headers, use method@MessageHeaders.get_list.
If @hdrs does erroneously contain multiple copies of the header, it is not defined which one will be returned. (Ideally, it will return whichever one makes libsoup most compatible with other HTTP implementations.)
Return
the header's value or null if not found.
Parameters
name
header name
