Mandrill API 使用 Rails 4.2.5 Excon::Errors::SocketError

Question

我在 Rails 应用程序中使用 Mandrill 发送交易电子邮件。我使用 'mandrill-api' gem 并根据文档进行配置。

它在生产环境中运行良好，但在本地出现错误：

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：

Rails.application.configure do
  # Settings specified here will take precedence over those in config/application.rb.

  }
end

mandrill.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！

根据 Casper 在其评论中的建议，我编辑了 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
