Question

我已经在 ubuntu 14 中安装了 python3.7 。以下是我遵循的过程

下载了 python 3.7
./configure
sudo make
sudo make install

现在我正在运行以下代码

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

但是它在控制台上出现以下错误：

Traceback (most recent call last):
  File "test.py", line 2, in <module>
    resp = urlopen('https://github.com')
  File "/usr/local/lib/python3.7/urllib/request.py", line 222, in urlopen
    return opener.open(url, data, timeout)
  File "/usr/local/lib/python3.7/urllib/request.py", line 525, in open
    response = self._open(req, data)
  File "/usr/local/lib/python3.7/urllib/request.py", line 548, in _open
    'unknown_open', req)
  File "/usr/local/lib/python3.7/urllib/request.py", line 503, in _call_chain
    result = func(*args)
  File "/usr/local/lib/python3.7/urllib/request.py", line 1387, in unknown_open
    raise URLError('unknown url type: %s' % type)`enter code here`
urllib.error.URLError: <urlopen error unknown url type: https>

有人可以帮我吗？

Answer 1

发生错误的原因是您的Python是在没有SSL支持的情况下配置和构建的，并且当setTimeout(function() { //your datatable code }, 1000);从github.com重定向到http URL时，您会看到以下错误：https

检查您的配置日志，您会看到有关检测到不支持SSL的消息。

解决方案是安装所有必需的依赖项（在本例中为unknown url type: https或类似的东西），并从源头重新配置和重新构建Python。

尝试通过导入requests.get()库来使用requests函数。我在python 2.7上运行良好

import requests

r = requests.get('https://www.facebook.com/')
print type(r)
print r.status_code 
print r.headers
print r.headers['content-type']

输出：

    <class 'requests.models.Response'>
    200
