我一直在使用Python Requests库来刮取网站一段时间，但该网站最近更改了SSL证书，新的证书将无法验证请求 .

根据类似问题的答案，我已将请求和urllib3更新到最新版本(2.4.3和1.9.1)，并手动将CA证书添加到请求'cacert.pem(/ usr / local / lib / python2) . 7 / DIST-包/请求/ cacert.pem) .

我可以使用curl成功使用此cacert.pem文件，但仍然没有请求：

> curl --head --cacert /usr/local/lib/python2.7/dist-packages/requests/cacert.pem

我不确定在这一点上还有什么可以尝试的 . 任何帮助表示赞赏！
