使用scrapy+redis從一定量的淘寶詳情頁url獲取商品詳情已設置user-agent，已傳入cookie，已設置proxy-ip獲取url，response.status有時是200，有時是302，隨機改變1000個url，成功獲取商品信息大概有400多是否為cookie未傳入成功，還是proxy-ip不穩定？或者其他原因。請幫忙分析，謝謝！報錯Traceback：2017-07-1415:51:12[scrapy.core.engine]DEBUG:Crawled(200)(referer:None)2017-07-1415:51:12[requests.packages.urllib3.connectionpool]INFO:StartingnewHTTPSconnection(1):rate.taobao.com2017-07-1415:51:12[requests.packages.urllib3.connectionpool]DEBUG:"GET/detailCommon.htm?auctionNumId=10245430841HTTP/1.1"200None2017-07-1415:51:12[scrapy.core.scraper]DEBUG:ScrapedfromNone2017-07-1415:51:12[taobao]DEBUG:Read1requestsfrom'taobao:start_urls'2017-07-1415:51:12[scrapy.downloadermiddlewares.cookies]DEBUG:Sendingcookiesto:2017-07-1415:51:12[scrapy.downloadermiddlewares.redirect]DEBUG:Redirecting(302)tofrom2017-07-1415:51:12[scrapy.downloadermiddlewares.cookies]DEBUG:Sendingcookiesto:2017-07-1415:51:12[scrapy.core.engine]DEBUG:Crawled(200)(referer:None)['partial']2017-07-1415:51:12[scrapy.core.scraper]ERROR:Spidererrorprocessing(referer:None)
