在Rails中拯救第三方REST API异常

Question

我通过他们的REST API连接到Docusign。目前，我正在拯救所有我不明白的例外情况。我想挽救API抛出的某些异常。当我从API收到异常时，它会在控制台中显示以下内容：

{"errorCode"=>"USER_AUTHENTICATION_FAILED", "message"=>"One or both of Username and Password are invalid."}

他们的错误格式是：

(errorDetails.errorCode) and associated messages (errorDetails.message)

我如何通过他们发回给我的回复来拯救个别例外？我目前的代码是：

def show

  begin
    client = DocusignRest::Client.new
    [Other API actions]
  rescue [Rescue USER_AUTHENTICATION_FAILED here]
    [log exception here]
  rescue => e
    [log exception here]
  end

end

您可以提供多个您想要拯救的异常类：

struct UIViewAnimationOptions : RawOptionSetType {
    init(_ rawValue: UInt)
    init(rawValue rawValue: UInt)
    static var LayoutSubviews: UIViewAnimationOptions { get }
    static var AllowUserInteraction: UIViewAnimationOptions { get }
    static var BeginFromCurrentState: UIViewAnimationOptions { get }
    static var Repeat: UIViewAnimationOptions { get }
    static var Autoreverse: UIViewAnimationOptions { get }
    static var OverrideInheritedDuration: UIViewAnimationOptions { get }
}
