当我运行以下命令时：
# curl https://undisclosedwebsite.nl
我收到以下错误：
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: http://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
使用openssl s_client -connect https://undisclosedwebsite.nl进行一些调试后，我发现以下带有cURL的命令可以正常工作：
curl https://undisclosedwebsite.nl --cacert /etc/ssl/certs/ca-certificates.crt
cURL不应该使用这个文件吗？
