【问题描述】：

Python 2.7.3

从 Raspberry Pi 3 调用 API，API 日志显示它到达正确的端点并返回 200 状态代码，但来自 Pi 的 python 代码吐出一个巨大的错误堆栈。我在一些论坛上看到，总是抛出 ZeroReturnError 意味着没有任何问题，但这看起来很奇怪，因为我实际上无法从 try 的 except 块中获得响应的结果。

我的代码是字面意思

import requests
response = requests.get(<URL I AM USING>, json={JSON I AM USING})

不知道该怎么办。

Traceback (most recent call last):

File "music.py", line 13, in <module>
    response = requests.get(url, json={'blah':{'blah':'*********'}})

File "/usr/lib/python2.7/dist-packages/requests/api.py", line 60, in get
    return request('get', url, **kwargs)

【解决方案1】：

更多搜索让我认为是版本问题。

在 Raspberry Pi 上运行 sudo pip install urllib3 --upgrade 并清除它。

我收到关于安装 PySocks 的 DependencyWarning，但它现在可以正常工作。
