今天,要在新环境里运行一个python脚本,遇到下面的报错:
/usr/lib/python2.7/site-packages/urllib3/util/ssl_.py:160: 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 new......
报错跟安全策略相关,网上搜了下,是因为python版本的原因(用的是python2.7.5),解决办法要么升级python 版本,要么安装requests,
本着牵动最小的原则,决定采用后者,如下:
pip install requests[security]
安装完成后,重新运行python脚本,还是一样的报错,又尝试了
pip install pyopenssl ndg-httpsclient pyasn1(等同于安装requests)
安装完成后,重新运行python脚本,还是一样的报错,想到一个惯用伎俩——upgrade
pip install --upgrade requests[security]
安装完成后,重新运行python脚本,果然,不再报InsecurePlatformWarning错了
题外话:InsecurePlatformWarning的错没有了,但又报了另一个错CryptographyDeprecationWarning,详细信息如下:
/usr/lib64/python2.7/site-packages/cryptography/hazmat/primitives/constant_time.py:26: CryptographyDeprecationWarning: Support for your Python version is deprecated. The next version of cryptography will remove support. Please upgrade to a 2.7.x release that supports hmac.compare_digest as soon as possible.
utils.DeprecatedIn23
提醒升级python版本,但此时脚本不涉及安全的情况下,能够正常往下执行。
