Hey all,

I'm a new-ish user of libmicrohttpd and have over the past couple weeks

ventured for the first time into using POST data.

I'm implementing a server that has thusfar only used GET and we were getting

all of the key-value pairs using MHD_get_connection_values.  Something like:

   typedef std::pair<std::string, std::string> TArg;

   typedef std::vector<TArg> TArgs;

static int _get_params (void *cls, enum MHD_ValueKind , const char *key,

const char *data)

{

TArgs* args = (TArgs*)cls;

TArg arg(key, (data ? data : ""));

args->push_back (arg);

return MHD_YES;

}

and then in the answer callback passed to MHD_start_daemon, there's a line:

TArgs args;

MHD_get_connection_values (connection, t, _get_params, &args);

Ensuring that _get_params will be iterated over to get all the values and

stock them in TArgs.

All of this works well in GET and we'd like to set up the same thing in

POST.  However, reading over POST, I don't see a clean way to iterate over

keys and values in the same manner.  I've followed through the tutorials and

can create postprocessors for single keys that handle uploads of large

chunks of data, but I can't figure out how to do the above sort of

manipulation.  Does anyone have any intuition about how the above could be

done via POST?

That accumulates the key: value pairs in a map (since we don't care
about multiple keys in this case).

That's exactly what I needed -  thank you!
