_ssl.c：351：错误：140B0009：SSL例程：SSL_CTX_use_PrivateKey_file：PEM库

Question

I want to connect to a web server that has a self-signed certificate, with Requests:

try:
    requests.get(url, cert=PATH_CERTIFICATE)
except requests.exceptions.ConnectionError as e:
    logger.info(e)

But it fails with the following:

[Errno 336265225] _ssl.c:351: error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:PEM lib

I got this certificate by running this command:

openssl s_client -showcerts -ssl3 -connect <hostname:port>

Answer 1

使用verify关键字，而不是cert ：

requests.get(url, verify=PATH_CERTIFICATE)
