Which urllib I should choose?
提问by Mathew P. Jones
as we know, python has two built-in url lib:
我们知道，python 有两个内置的 url 库：
urlliburllib2
urlliburllib2
and a third-party lib:
和第三方库：
urllib3
urllib3
if my requirement is only to request a API by GET method, assume it return a JSON string.
which lib I should use? do they have some duplicated functions?
if the urllibcan implement my require, but after if my requirements get more and more complicated, the urllibcan not fit my function, I should import another lib at that time, but I really want to import only one lib, because I think import all of them can make me confused, I think the method between them are totally different.
如果我的要求只是通过 GET 方法请求 API，假设它返回一个 JSON 字符串。
我应该使用哪个库？他们有一些重复的功能吗？
如果urllib可以实现我的require，但是之后如果我的需求越来越复杂，urllib不能适应我的功能，我当时应该再导入一个库，但我真的只想导入一个库，因为我认为导入所有它们会让我感到困惑，我认为它们之间的方法完全不同。
so now I am confused which lib I should use, I prefer urllib3, I think it can fit my requirement all time, how do you think?
所以现在我很困惑我应该使用哪个库，我更喜欢urllib3，我认为它可以一直满足我的要求，你觉得如何？

As Alexander says in the comments, use requests. That's all you need.
正如亚历山大在评论中所说，使用requests. 这就是你所需要的。

Personally I avoid to use third-party library when possible, so I can reduce the dependencies' list and improve portability. urllib and urllib2 are not mutually exclusive and are often mixed in the same project.
我个人尽可能避免使用第三方库，这样我可以减少依赖项的列表并提高可移植性。urllib 和 urllib2 并不相互排斥，经常混在同一个项目中。
