描述

Passing a data URL (such as "data:text/plain,hello") to urlopen raises a URLError, although this works in both Python 2.7 and Python 3.5. I'm not sure if this was added after Python 3.3 on which the backports code is based according to the source, but according to the 3.3 documentation it seems that it should have worked even in Python 3.3.

研究方向
Investigate the implementation of urllib.request.urlopen in the future.backports module. Compare the behavior with Python 3.3's urllib to see if data URL support was added in later versions. Determine the exact code difference needed to support data URLs while maintaining compatibility with Python 2. Ensure the fix aligns with the library's goal of backporting functionality from Python 3.x.
