爬虫关于cookie的问题

Question

在爬虫的时候 为啥有时候cookie 写到header 里面才能返回 有时候需要单独穿cookie 才能返回数据呢？否则显示未登录

self.cookie_str = "acw_tc=b65cfd2515395760831792797e7a30fed7278a95d7c68d0dcad0b9cbc4ac1b; kwlo_iv=1h; kr_stat_uuid=TRRfp25694452; Hm_lvt_e8ec47088ed7458ec32cde3617b23ee3=1541062621,1541150329,1541661241; Hm_lpvt_e8ec47088ed7458ec32cde3617b23ee3=1541667148; download_animation=1; _kr_p_se=9867c144-9614-4298-96f7-0e46ed5efefe; krid_user_id=2014445492; krid_user_version=2; kr_plus_id=2014445492; kr_plus_token=8dnyAhS2t87wW1PU1p91L_jUAHPFmepeJJ75____; kr_plus_utype=0; device-uid=5fa2cef0-e334-11e8-978f-67115035d613"
