Scrapy - How to get duplicate request referer












1















When I turn on DUPEFILTER_DEBUG, I got:




2016-09-21 01:48:29 [scrapy] DEBUG: Filtered duplicate request: http://www.example.org/example.html>




The problem is, I need to know the duplicate request's referrer to debug the code. How can I debug the referrer?

  • Try implementing your own visited log, in memory or in file, by for example using a yielded links pipeline.

One option would be a custom filter based on the built-in RFPDupeFilter filter:



from scrapy.dupefilters import RFPDupeFilter

class MyDupeFilter(RFPDupeFilter):
def log(self, request, spider):
self.logger.debug(request.headers.get("REFERER"), extra={'spider': spider})
super(MyDupeFilter, self).log(request, spider)


Don't forget to set the DUPEFILTER_CLASS setting to point to your custom class.
