unirest 支持 python3 吗？

Question

unirest 支持 python3 吗？我用谷歌搜索了零信息。即使在the unirest documentation 中，它也没有说它只是 2.x，这让我相信它同时支持 3.x 和 2.x。但是安装失败并使用 3.4 并成功使用 2.7。见下文。

nkltss:~/dev$ mkvirtualenv mashape -p /usr/bin/python3

目前我使用的是 2.7，但我更喜欢将 3.x 用于新项目。

Answer 1

该项目不兼容 Python 3。当项目没有明确说明这一点时（不在setup.py trove 分类器或文档中），您必须查看source code。

我找到了：

• no use_2to3 use in setup 在安装时自动重写代码
• imports for urllib2，仅限 Python 2 的库。

项目依赖poster library，也就是urllib2 specific。

我会改用requests library。它开箱即用地支持 Python 3，除了异步请求外，它还支持相同的功能集（但更好，因为它没有 urllib2 带来的缺点）。对于异步请求，您可以添加requests-futures。
