Post image base64 using Flurl

Question

I'm trying to post simple request using Flurl. But there is an exception, because takenPicture string is too large. Is there any way to post large string using Flurl?

System.UriFormatException: Uri is longer than the maximum 32766 characters.

var postData = BaseAdress.PostUrlEncodedAsync(new {
   text = Uri.EscapeDataString(body),
   subject = Uri.EscapeDataString(subject),
   from_email = from,
   recipient_email = to,
   picture = takenPicture //Base64 string
});

This limitation, while a little arbitrary, is by design in Microsoft's Uri.EscapeDataString method, which is commonly used by applications and libraries (including Flurl) to encode data for both URL queries and URL-encoded request bodies. Both Xamarin and RestSharp Portable have dealt with this so I'm sure a work-around is possible and I might consider this in Flurl if you want to create an issue.

However, keep in mind that URL-encoding binary data like images is very unusual, and there are good reasons to avoid it if possible. Of course, if this is a 3rd-party API you're working with, you don't have much of a choice. But if you have control of the server-side code, I would suggest refactoring that to accept multipart/form-data instead.
