Deprecated 'Request' objects like "has_data()" and "get_data()" are still present in 'streaminghttp.py' which cannot be run on 3.4 and higher versions

Please change the deprecated objects in such a way that it will not effect somewhere else in the code. I have made changes with this code locally. But these changes are effecting elsewhere in some other dependent code of mine.
