Question

当我使用以下命令在python3中使用requests.get()函数时

import requests
res = requests.get('http://www.gutenberg.org/cache/epub/1112/pg1112.txt')

然后python3抛出以下错误：

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/urllib3/connectionpool.py", line 557, in urlopen
    body=body, headers=headers)

据我所知，它没有互联网连接，但我的互联网工作正常。那么为什么python会抛出这个错误呢？

Answer 1

您可以使用（以秒为单位）增加超时： requests.get（'http://www.gutenberg.org/cache/epub/1112/pg1112.txt'，timeout = 30）

Answer 2

使用alpbert帮助和此主题Proxies with Python 'Requests' module

找到答案

我没有任何代理，但python仍在尝试检测代理。所以我创建了一个dict元素

代理= { 'HTTP'： ''}

然后这个命令工作

res = requests.get（'http://www.gutenberg.org/cache/epub/1112/pg1112.txt'，proxies = proxies）

在python3中使用request.get函数时出错
