[AWS] Reading the body of a POST as a String

I see, that's because it is overloaded and can be ambiguous in some 
cases, but for this you can use a qualified expression:

    MB : constant String := String'(AWS.Response.Message_Body (R));

Or if you have two procedure:


    procedure P (M : String);
    procedure P (M : Unbounded_String);

P (String'(AWS.Response.Message_Body (R)));

Note that if the message body is expected to be large it is better to 
use the Unbounded_String version to avoid a stack overflow.

Pascal.
