urllib 无法读取 https [英] urllib cannot read https

问题描述

(Python 3.4.2)有人能帮我用 urllib 获取 https 页面吗?我花了几个小时试图弄清楚这一点.

(Python 3.4.2) Would anyone be able to help me fetch https pages with urllib? I've spent hours trying to figure this out.

这是我想要做的(非常基本的):

Here's what I'm trying to do (pretty basic):

import urllib.request
url = "".join((baseurl, other_string, midurl, query))
response = urllib.request.urlopen(url)
html = response.read()

这是我运行时的错误输出:

Here's my error output when I run it:

File "./script.py", line 124, in <module>
    response = urllib.request.urlopen(url)
  File "/usr/lib/python3.4/urllib/request.py", line 153, in urlopen
    return opener.open(url, data, timeout)
  File "/usr/lib/python3.4/urllib/request.py", line 455, in open
    response = self._open(req, data)
  File "/usr/lib/python3.4/urllib/request.py", line 478, in _open
    'unknown_open', req)
  File "/usr/lib/python3.4/urllib/request.py", line 433, in _call_chain
    result = func(*args)
  File "/usr/lib/python3.4/urllib/request.py", line 1244, in unknown_open
    raise URLError('unknown url type: %s' % type)
urllib.error.URLError: <urlopen error unknown url type: 'https>

我也试过使用 data=None 无济于事:

I've also tried using data=None to no avail:

response = urllib.request.urlopen(url, data=None)

我也试过这个:

import urllib.request, ssl
https_sslv3_handler = urllib.request.HTTPSHandler(context=ssl.SSLContext(ssl.PROTOCOL_SSLv3))
opener = urllib.request.build_opener(https_sslv3_handler)
urllib.request.install_opener(opener)
resp = opener.open(url)
html = resp.read().decode('utf-8')
print(html)

这个^脚本出现了类似的错误，错误出现在resp = ..."行并抱怨https"是未知的url类型.

A similar error occurs with this^ script, where the error is found on the "resp = ..." line and complains that 'https' is an unknown url type.

Python 在我的计算机 (Arch Linux) 上编译时支持 SSL.我试过重新安装 python3 和 openssl 几次，但这没有帮助.我没有尝试完全卸载python然后重新安装，因为我还需要卸载计算机上的许多其他程序.

Python was compiled with SSL support on my computer (Arch Linux). I've tried reinstalling python3 and openssl a few times, but that doesn't help. I haven't tried to uninstall python completely and then reinstall because I would also need to uninstall a lot of other programs on my computer.

有人知道这是怎么回事吗?

Anyone know what's going on?

-----EDIT-----

我想通了，感谢 Andrew Stevlov 的回答.我的网址中有一个:"，我猜 urllib 不喜欢那样.我用%3A"替换了它，现在它可以工作了.非常感谢大家！！！

I figured it out, thanks to help from Andrew Stevlov's answer. My url had a ":" in it, and I guess urllib didn't like that. I replaced it with "%3A" and now it's working. Thanks so much guys!!!

推荐答案

仔细检查你的编译选项，看起来你的盒子有问题.

Double check your compilation options, looks like something is wrong with your box.

至少以下代码对我有用:

At least the following code works for me:

from urllib.request import urlopen
resp = urlopen('https://github.com')
print(resp.read())
