Re: [libmicrohttpd] Retrieving GET parameters in form http://...?wsdl

[Christian Grothoff]

Hi!

This is a good question, I didn't think this kind of HTTP request was 
even legal...  But I think we could make it work.  First of all, the 
current code just throws the "wsdl" away, but we can fix that:

$ svn diff
Index: src/daemon/connection.c
===================================================================
--- src/daemon/connection.c     (revision 17024)
+++ src/daemon/connection.c     (working copy)

     {
       equals = strstr (args, "=");
       if (equals == NULL)
-        return MHD_NO;          /* invalid, ignore */
+       {
+         /* add with 'value' NULL */
+	  connection->daemon->unescape_callback 
(connection->daemon->unescape_callback_cls,
+                                                connection,
+                                                args);
+       
+         return connection_add_header (connection,
+                                       args,
+                                       NULL,
+                                       kind);
+       }
       equals[0] = '\0';
       equals++;
       amper = strstr (equals, "&");

With that change, you should then be able to get to the data using 
'MHD_get_connection_values'.  You would be called with a key of "wsdl" 
and a value of NULL.  If the URL had been "...?wdsl=" the value would be 
the empty string ("").

This is just how I suggest we should do this, I didn't test this yet.

Happy hacking,

Christian
