在Scrapy里设置Cookies 要注意一点！

1.requests里设置cookies,可以将cookies放入headers里一同提交。

 

{‘Accept‘: ‘text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8‘,
 ‘Accept-Encoding‘: ‘gzip, deflate‘,
 ‘Accept-Language‘: ‘zh-CN,zh;q=0.9,en;q=0.8‘,
 ‘Cache-Control‘: ‘max-age=0‘,
 ‘Connection‘: ‘keep-alive‘,
 ‘Cookie‘: ‘__cfduid=d50cf692a2f654986d51b98e6c1bad6c41535939301; session=.eJwlzj0OwjAMQOG7eO6Q2Emc9DKV6x-oEB1amBB3pxLS27_3gSUOP-8wv463T7BsBjMEiaIRMZe-MgfXKozmShqWXZVMOqdW-jDElkbm2r2IKqt0WYkwczKLNjyKmqUW2Nekgv3KMg2mWp1TRcm54ShNROvl5FARmOB9-vGfeWz7bZenw_cHGzsyUA.Dw5FeA.xD0ofpGXJUvDLYeCrMn08E24HKM‘,
 ‘DNT‘: ‘1‘,
 ‘Host‘: ‘exercise.kingname.info‘,

 ‘User-Agent‘: ‘Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36‘}

 

 

 

2.但是，如果使用Scrapy的时候需要Cookies，就不能把Cookies放在Headers里面。在Scrapy发起请求的时候，有一个单独的参数来设置Cookies：

yield scrapy.Request(url,
                     callback=self.xxx,
                     headers=headers,
                     cookies={‘__cfduid‘: ‘d50cf692a2f654986d51b98e6c1bad6c41535939301‘,
                              ‘session‘: ‘.eJwlzj0OwjAMQOG7eO6Q2Emc9DKV6x-oEB1amBB3pxLS27_3gSUOP-8wv463T7BsBjMEiaIRMZe-MgfXKozmShqWXZVMOqdW-jDElkbm2r2IKqt0WYkwczKLNjyKmqUW2Nekgv3KMg2mWp1TRcm54ShNROvl5FARmOB9-vGfeWz7bZenw_cHGzsyUA.Dw5FeA.xD0ofpGXJUvDLYeCrMn08E24HKM‘})
