Pycurl HTTPS错误原因及解决

Posted 2021-04-30 老柴的自留地

问题现象：使用pycurl访问百度时，提示connection error:(60, 'SSL certificate problem: unable to get local issuer certificate')

问题原因：百度全站已经使用ssl，pycurl访问https时检测不到本地证书，需要手工指定

解决方法：

1. 设置不校验ssl证书，跳过检测过程

   curl.setopt(pycurl.SSL_VERIFYPEER,0)

   
   

2. 使用pip安装certifi，

   Certifi is a carefully curated collection of Root Certificates for validating the trustworthiness of SSL certificates while verifying the identity of TLS hosts. It has been extracted from the Requests project.
   

   
   

   pip install certifi

   import pycurl

   import certifi

   curl.setopt(pycurl.SSL_VERIFYPEER,2)

   curl.setopt(pycurl.SSL_VERIFYHOST,2)

   curl.setopt(pycurl.CAINFO,certifi.where())

以上测试通过，可以正常访问https://www.baidu.com
