Python requests 报错解决集锦

python版本号和ssl版本号都会导致 requests在请求https站点时候会出一些错误，最好使用新版本号。

1 Python2.6x use requests

一台老Centos机器上跑着古老的应用，加了一个新模块之后报错 报错 InsecurePlatformWarning: A true SSLContext object is not available.

/usr/lib/python2.6/site-packages/requests/packages/urllib3/util/ssl_.py:132: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. You can upgrade to a newer version of Python to solve this. For more information, see https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings
  InsecurePlatformWarning

解决的方法
使用老版本号的 requests

$pip install requests==2.5.3

或者这样安装

$ pip install requests[security]

2 SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

错误例如以下 版本号 python2.7.5

Traceback (most recent call last):
  File "./test.py", line 24, in <module>
  response = requests.get(url1, headers=headers)
  File "build/bdist.linux-x86_64/egg/requests/api.py", line 52, in get
  File "build/bdist.linux-x86_64/egg/requests/api.py", line 40, in request

requests.exceptions.SSLError: [Errno 1] _ssl.c:503: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

解决方法
能够禁用 verify

>>> requests.get('https://google.com', verify=False)

问题地址 python-requests-throwing-up-sslerror

3 SSLError: bad handshake

SSLError: bad handshake: Error([(‘SSL routines’, ‘SSL3_GET_SERVER_CERTIFICATE’, ‘certificate verify failed’)],) python2.7.5

pip uninstall -y certifi && pip install certifi==2015.04.28
