【问题描述】：

我在我的 Rails 应用程序中使用 Mandrill 来发送交易电子邮件。我使用了'mandrill-api' gem，并根据文档进行了配置。

它在生产中运行良好，但在本地出现错误突袭：

Unable to verify certificate, please set `Excon.defaults[:ssl_ca_path] = path_to_certs`, 
`ENV['SSL_CERT_DIR'] = path_to_certs`, `Excon.defaults[:ssl_ca_file] = path_to_file`, `ENV['SSL_CERT_FILE'] = path_to_file`, 
`Excon.defaults[:ssl_verify_callback] = callback` (see OpenSSL::SSL::SSLContext#verify_callback), 
or `Excon.defaults[:ssl_verify_peer] = false` (less secure).

我不明白为什么它在生产而不是在本地工作？

这是我的配置：

end

ma​​ndrill.rb

require 'mandrill'

# Use an environment variable instead of placing the key in source code
MANDRILL = Mandrill::API.new ENV['MANDRILL_API_KEY'], true

仅在本地引发错误的函数：

  def send_short_email(subject, message, receiver)
    inner_message = 
      to:  [name: receiver.name, type: 'to', email: receiver.email],
      subject: subject,
      html: message,
      text: message,
      from_email: ENV['DEFAULT_EMAIL_SENDER']
    
    MANDRILL.messages.send inner_message
    logger.debug inner_message
  end

我尝试更改设置、主机或 API 密钥，但没有任何效果。而且 gem 文档中也没有提到这个问题。

你有什么想法吗？

谢谢！

【问题讨论】：

这是 Excon 的 SSL 证书问题。可能与此相关或相同的问题：github.com/excon/excon/issues/473

这可能也值得一读：github.com/excon/excon/issues/239

我阅读了它们，但我不知道如何解决问题。 :-( 也许删除并重新安装 Ruby？

因为它是您的开发机器，您可以尝试跳过证书验证。设置Excon.defaults[:ssl_verify_peer] = false 并尝试。但仅在您的开发机器上，在生产环境中使用是不安全的。

你是我的救星。它正在工作:-) 谢谢！

【参考方案1】：

正如 Casper 在其评论中所建议的，我编辑了我的 development.rb 文件以跳过证书验证。

development.rb

require 'excon'
Rails.application.configure do
     ...
     Excon.defaults[:ssl_verify_peer] = false
end
