Middlewares that don't have either of these methods don't need to use this class. You can override the :meth:`~scrapy.spidermiddlewares.base.BaseSpiderMiddleware.get_processed_request` method to add processing code for requests and the :meth:`~scrapy.spidermiddlewares.base.BaseSpiderMiddleware.get_processed_item` method to add processing code for items. These methods take a single request or item from the spider output iterable and return a request or item (the same or a new one), or ``None`` to remove this request or item from the processing. cXlgNcrawler)selfrs d/root/1688_scrapy/alibaba-scraper/venv/lib/python3.13/site-packages/scrapy/spidermiddlewares/base.py__init__BaseSpiderMiddleware.__init__$s ' cU"U5$r)clsrs r from_crawler!BaseSpiderMiddleware.from_crawler's 7|rc#T# UHnURUS5=ncMUv M g7fr_get_processed)rstartspideros rprocess_start_requests+BaseSpiderMiddleware.process_start_requests+s.A((D11>s( (cd# UShvN nURUS5=ncM U7v M'N" g7frr)rr!r#s r process_start"BaseSpiderMiddleware.process_start2s3 !((D11> us 0.,.00.0c#R# UHnURXA5=ncMUv M g7frrrresponseresultr"r#s rprocess_spider_output*BaseSpiderMiddleware.process_spider_output7s,A((55Bs' 'cb# UShvN nURXA5=ncMU7v M&N! g7frrr*s rprocess_spider_output_async0BaseSpiderMiddleware.process_spider_output_async>s3 !((55B vs /-+-//-/cp[U[5(aURX5$URX5$r) isinstancerget_processed_requestget_processed_item)rr#r+s rr #BaseSpiderMiddleware._get_processedEs1 a ! !--a: :&&q33rcU$)aReturn a processed request from the spider output.
