Just for my curiosity.

Why don't using

-G

http://curl.haxx.se/docs/manpage.html

###########
-G, --get

When used, this option will make all data specified with -d, --data,
--data-binary or --data-urlencode to be used in an HTTP GET request
instead of the POST request that otherwise would be used. The data will
be appended to the URL with a '?' separator.

If used in combination with -I, the POST data will instead be appended
to the URL with a HEAD request.

If this option is used several times, only the first one is used. This
is because undoing a GET doesn't make sense, but you should then instead
enforce the alternative method you prefer.
