Default Fields in Scraping Agent

Agenty CSS Selector and REGEX extractor engine can be used to extract anything you want from the source content, but sometime you might want few fields to be included in your output result which is not the part of website source content. For example you are scraping stock information of 100 companies from a stock website but also want a DATETIME field should also be in your output result to see when a particular page was fetched and information was extracted.

So Agenty offers the built-in default fields to add in your agent for all those cases when needed :

Name Type Description
REQUEST_URL string URL of web page, same as in provided in input

URL of web page returned by web server even after redirects.
(E.g. If your inputs has an old URL but web server returns a 301 redirect and serves the new URL . The RESPONSE_URL field will have the new URL populated)

RESPONSE_HTTP_CODE int HTTP Code of successful web request (E.g. 200, 301)
RESPONSE_HTTP_STATUS string HTTP Status of successful web request (E.g. Ok, Moved Permanently)
RESPONSE_ERROR_CODE int HTTP Error code of error-ed web request(E.g. 404, 408, 503 etc.)

HTTP Error message of error-ed web request. E.g.

  • Not Found
  • Request Time Out
  • Website under maintenance etc.

Content-Type:text/html; charset=utf-8

How to add a DEFAULT field 

  1. Edit your agent in agent editor (Create one if you don't have any agent, the DEFAULT fields can be added after the agent is created)
  2. Then go to "Collections" tab and click on "Add field" button to add a field.
  3. Change the Type as DEFAULT
  4. Select the default field you want to add in "From" drop-down box as in screenshot below
    add default field
  5. Finally, save the scraping agent configuration.

The above steps will change the scraping agent configuration only and you'd need to re-run your agent to extract the default field value when the field is added or updated.
