Add support for formdata in body parameter.

[lionuncle]

Please add support for form data in HTTP post request body parameter.

I was using map as parameter, but the API accepts form data only. So, I always got "bad data" error.

Then I shifted to DIO and worked like a charm!

After hours of wondering, I found that HTTP does not support formdata yet.

Please add the feature. Many thanks!

It took me a long time to discover this problem. Always gives type error in variables. Please add support for "form-data". Thanks!
