Question

我在这里丢失了一些东西，但是由于某种原因，我的runserver.py和begin Ruby代码无法捕获此错误：

rescue

这是我的代码：

#<ActiveResource::ResourceInvalid: Failed.  Response code = 422.  Response message = Unprocessable Entity.>

它永远不会捕获它。在我的begin ShopifyAPI::CarrierService.create(with some arguments) rescue StandardError => e pp e end部分中，我尝试了以上操作，但也进行了以下操作：

rescue

一切都没有运气。我在哪里迷路了？

谢谢

编辑：这是一个完整的错误，它不再是真正的信息了，但是在这里：

 rescue Exception => e
 rescue ActiveResource::Errors => e

就是这样！

Answer 1

因为它没有引发异常，所以如果您想在响应为假时引发异常，则可能必须使用create with bang

begin
 ShopifyAPI::CarrierService.create!(with some arguments)
rescue StandardError => e
  pp e
end

Answer 2

根据ActiveResource代码（lib / active_resource / base.rb）：

# <tt>404</tt> is just one of the HTTP error response codes that Active Resource will handle with its own exception. The
# following HTTP response codes will also result in these exceptions:
#
# * 200..399 - Valid response. No exceptions, other than these redirects:
# * 301, 302, 303, 307 - ActiveResource::Redirection
# * 400 - ActiveResource::BadRequest
# * 401 - ActiveResource::UnauthorizedAccess
# * 403 - ActiveResource::ForbiddenAccess
# * 404 - ActiveResource::ResourceNotFound
...
# * 422 - ActiveResource::ResourceInvalid (rescued by save as validation errors)

因此，它表明通过保存验证来挽救422，这是在触发.create时发生的，并冒泡为验证错误。

查看lib / active_resource / validations.rb，可以看到ResourceInvalid异常被吞噬了：

# Validate a resource and save (POST) it to the remote web service.
# If any local validations fail - the save (POST) will not be attempted.
def save_with_validation(options={})
  perform_validation = options[:validate] != false

  # clear the remote validations so they don't interfere with the local
  # ones. Otherwise we get an endless loop and can never change the
  # fields so as to make the resource valid.
  @remote_errors = nil
  if perform_validation && valid? || !perform_validation
    save_without_validation
    true
  else
    false
  end
rescue ResourceInvalid => error
  # cache the remote errors because every call to <tt>valid?</tt> clears
  # all errors. We must keep a copy to add these back after local
  # validations.
  @remote_errors = error
  load_remote_errors(@remote_errors, true)
  false
end

因此，我想知道是否正在记录是否发生了异常，但实际上并没有引发异常，因为它将异常返回了false。它确实在注释中说了“本地验证”，但是设置了remote_errors，因此尚不清楚该代码路径在何处执行。
