How do you log the URL ActiveResource uses?

问题

Rails ActiveResource is awesome ... except for one thing: as far as I can tell, there is no way to see what URL it is using behind the scenes. For instance, let's say I have an ActiveResource called Issue, for a webservice at myIssues.com/issues.xml. If I do:

Issue.find(:all, :params => {:page => 2})

I would expect that ActiveResource would make a call to:

myIssues.com/issues.xml?page=2

... but I don't actually know that. For all I know, ActiveResource could have decided it doesn't like the word "page", so it's actually using:

myIssues.com/issues.xml?mod_page=2

This makes debugging difficult. Right now I've got a situation where, if I go to the URL I think ActiveResource is using, it works just fine. However, when I actually use ActiveResource, it doesn't work. Seeing the URL it's GETing would be immensely helpful in this, so ...

Does anyone know a way to log (or otherwise output; if there's some resource.url method that would work great too) the URL(s) that ActiveResource uses to do its thing?

回答1:

If you add the following line to your environment.rb file, it will at least log the requests so you know that URLs ActiveResource is hitting:

ActiveResource::Base.logger = ActiveRecord::Base.logger

I'm still searching for a better solution that shows me the response and the data posted to update calls, but at least this is a step in the right direction. I'm really not sure why ActiveResource has a separate logger to start with, but that's another matter.

回答2:

I just ran into this same exact issue, and came across this post as I was looking for answers. What I did find, that proved useful, is the collection_path method on ActiveResource::Base. So for example, let's say you have the following resource:

class UserPost < ActiveResource::Base
    self.site = "http://someApp.com/user/:user_id"
    self.element_name = "post"

If you go to the rails console, here are some examples of the output:

>> UserPost.collection_path
"/user//post"
>> UserPost.collection_path(:user_id => 5)
"/user/5/post

This should provide you with exactly what you need to determine how ActiveResource is translating your request into a URL.

To get detail login for ActiveResource have to patch the request method inside the gem(method.

place bellow files inside config/initializers you will get http method, path, request body, request hedaers

response body and header is already there if you need. doc

config/initializers/activeresource_patch.rb

module ActiveResource
  class Connection
    private
      def request(method, path, *arguments)
        result = ActiveSupport::Notifications.instrument("request.active_resource") do |payload|
          payload[:method]      = method
          payload[:request_uri] = "#{site.scheme}://#{site.host}:#{site.port}#{path}"
          payload[:request_path] = path
          payload[:request_body] = arguments[0]
          payload[:request_headers] = arguments[1]
          payload[:result]      = http.send(method, path, *arguments)
        end
        handle_response(result)
      rescue Timeout::Error => e
        raise TimeoutError.new(e.message)
      rescue OpenSSL::SSL::SSLError => e
        raise SSLError.new(e.message)
      end
  end
end

config/initializers/activeresource_logger.rb

Rails.application.configure do

  def activeresource_logger
  @activeresource_logger ||= Logger.new("#{Rails.root}/log/activeresource_logger.log")
  end

  ActiveSupport::Notifications.subscribe('request.active_resource')  do |name, start, finish, id, payload|
   if Rails.env.development?
    activeresource_logger.info("====================== #{start} : #{payload[:method].upcase} ======================")
    activeresource_logger.info("PATH: #{payload[:request_path]}")
    activeresource_logger.info("BODY: #{payload[:request_body]}")
    activeresource_logger.info("HEADERS: #{payload[:request_headers]}")
    # activeresource_logger.info("STATUS_CODE: #{payload[:result].code}")
    # activeresource_logger.info("RESPONSE_BODY: #{payload[:result].body}")
   end
  end

end
