错误urllib2 Python.SSL:TLSV1_ALERT_INTERNAL_ERROR ssl.c:590

Question

我正在尝试使用urllib for Python来打开一个URL但是我得到一个错误,其中一个特定的URL与其他URL相比看起来很正常,并且在浏览器中运行良好.

生成错误的代码是:

import cStringIO
import imghdr
import urllib2
response = urllib2.urlopen('https://news.artnet.com/wp-content/news-upload/2015/08/Brad_Pitt_Fury_2014-e1440597554269.jpg')

但是,如果我使用类似的URL执行完全相同的操作,则不会收到错误:

import cStringIO
import imghdr
import urllib2
response = urllib2.urlopen('https://upload.wikimedia.org/wikipedia/commons/d/d4/Brad_Pitt_June_2014_(cropped).jpg')

我在第一个例子中得到的错误是:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 154, in urlopen
    return opener.open(url, data, timeout)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 431, in open
    response = self._open(req, data)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 449, in _open
    '_open', req)

    result = func(*args)

  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 1197, in do_open
    raise URLError(err)
urllib2.URLError: <urlopen error [SSL: TLSV1_ALERT_INTERNAL_ERROR] tlsv1 alert internal error (_ssl.c:590)>

我在 urllib3 文档中找到了非常好的解释。

以下代码解决了 Python 2.7.10 的问题：

import urllib3 
import ssl 
import certifi
urllib3.contrib.pyopenssl.inject_into_urllib3()

# Open connection
http = urllib3.PoolManager(
    cert_reqs='CERT_REQUIRED', # Force certificate check.
    ca_certs=certifi.where(),  # Path to the Certifi bundle.
)

# Make verified HTTPS requests. 
try:
    resp = http.request('GET', url_photo) 
except urllib3.exceptions.SSLError as e:
    # Handle incorrect certificate error.
    print "error with https certificates"
