[英]Suppress 'SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed' errors in python
[英]SSL3_GET_SERVER_CERTIFICATE certificate verify failed on Python when requesting (only) *.google.com
我遇到了一個非常奇怪的錯誤,它與SSL和python有關google.com(或者更常見的是我認為有多個證書鏈的域名)。 每當我嘗試向https://*.google.com/whatever
請求時,我都會收到以下錯誤消息:
SSLError: ("bad handshake: Error([('SSL routines', 'SSL3_GET_SERVER_CERTIFICATE', 'certificate verify failed')],)",) while doing GET request to URL: https://google.com/
我已經經歷了很多嘗試讓這個工作起來的箍,並且現在因為我不知道該怎么做而訴諸Stack Overflow。 這是我嘗試過的:
注意到date
返回的日期比實時晚了2分鍾(可能使我的證書無效)。 假設它會驗證證書,我修復了這個問題。 這並沒有解決問題。
發現Python 2.7.9從Python 3向后移植了一些SSL庫。我從Python 2.7.6升級到2.7.9,假設更新(包括此線程中列出的修復程序: https : //serverfault.com/questions/692110/錯誤-python2-as-a-https-client-with-an-nginx-server-and-ssl-certificate-ch )會解決它。 沒有運氣,同樣的錯誤。
顯然設置verify=False
有效,但我們不願意在安全方面做出讓步,我們需要得到verify=True
才能工作。
curl https://google.com
也按預期工作。 這就是我知道它與Python有關的方式。
$ python -V
Python 2.7.9
$ pip list | grep -e requests
requests (2.9.1)
$ uname-a # ubuntu 14.04

這僅適用於https上的Google域名。 這是一個例子:

我找到了解決方案。 在運行的certifi
版本中似乎存在一個主要問題。 我從這個(非常長的)GitHub問題中找到了這個: https : //github.com/certifi/python-certifi/issues/26
TL; DR
pip uninstall -y certifi && pip install certifi==2015.04.28
