SSL_connect 返回=1 errno=0 状态=错误：证书验证失败（无法获取本地颁发者证书）

我正在尝试从我的应用程序发布到网络服务，但经常收到以下错误。

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

我用compassplus发出的crt文件和我自己生成的密钥文件发送post请求。

def payment
    @booking = 12

    uri = URI("https://test.compassplus.com:8444/Exec")
    xml = Builder::XmlMarkup.new
    xml.instruct! :xml, :version => '1.0'
    xml.TKKPG {
        xml.Request {
            xml.Operation("CreateOrder")
            xml.language("EN")
            xml.Order {
                xml.OrderType("Purchase")
                xml.Merchant("123456")
                xml.Amount("10000")
                xml.Currency("840")
                xml.Description("Tour Purchase")
                xml.ApproveURL("/thankyou.html")
                xml.CancelURL("/error.html")
                xml.DeclineURL("/declined.html")
                xml.email("")
                xml.phone("")
                xml.AddParams {
                    xml.FADATA("")
                    xml.SenderPostalCode("")
                    xml.AcctType("")
                    xml.TranAddendums("")
                    xml.TranAdddendumsVISA("")
                    xml.TranAdddendumsMC("")
                    xml.TranAdddendumsAMEX("")
                    xml.TranAdddendumsJCB("")
                    xml.OrderExpirationPeriod("")
                    xml.OrigAmount("")
                    xml.OrigCurrency("")
                }
            }
        }
    }
    http = Net::HTTP.new(uri.host, uri.port)
    http.use_ssl  = true
    http.ssl_version = :TLSv1_2
    http.verify_mode  = OpenSSL::SSL::VERIFY_PEER
    http.ca_file = File.read(File.join(Rails.root, "/crt/gvtrek.com.pem"))

    @request = http.post(uri, xml)
end

当我从本地主机发送 post 请求时出现 SSL 错误，当我从生产环境发送请求时出现超时。我无法弄清楚问题所在。帮我解决它。我正在 macOS Mojave 上工作。

经过大量测试，我找到了正确的解决方案。问题出在证书文件声明上。

我尝试使用捆绑的证书文件（example.com.pem）发送发布请求

http.ca_file = File.read(File.join(Rails.root, "/crt/example.com.pem"))

因此，我用每个 crt 和密钥文件更改了上述声明

http.cert = OpenSSL::X509::Certificate.new(File.read(File.join(Rails.root, "/crt/example.com.crt")))
http.key = OpenSSL::PKey::RSA.new(File.read(File.join(Rails.root, "/crt/example.com.key")))
req = Net::HTTP::Post.new(uri.path, initheader = {'Content-Type' =>'application/xml'}).

现在它起作用了。

用于 Ruby 的 HTTP 库是否具有 HTTPS、SSL 客户端证书和 Keep-Alive 支持？
