Always getting: SSL_connect returned=1 errno=0 state=error: certificate verify failed (unable to get local issuer certificate)

Question

我使用 ruby-saml gem 并尝试加载我的 IDP 的元数据但出现此错误：

> OneLogin::RubySaml::IdpMetadataParser.new.parse_remote('my IDP federation metadata XML URL')

Traceback (most recent call last):

OpenSSL::SSL::SSLError (SSL_connect returned=1 errno=0 state=error: certificate verify failed (unable to get local issuer certificate))

上面的错误是什么意思？

我试图查看我使用的是什么证书，它似乎是这样的：

[13] pry(#<OpenSSL::SSL::SSLContext>)> OpenSSL::X509::DEFAULT_CERT_FILE
=> "/usr/local/etc/openssl@1.1/cert.pem"
[14] pry(#<OpenSSL::SSL::SSLContext>)> OpenSSL::X509::DEFAULT_CERT_DIR
=> "/usr/local/etc/openssl@1.1/certs"

我的证书有问题吗？

注意：我已阅读但仍然不知道如何解决我的问题。此人手动使用证书，但我认为我不需要使用证书，因为代码应该处理证书？

Answer 1

IDP 端证书过期，他们修复了它并停止了相关错误。
