这是一个创建于 2355 天前的主题，其中的信息可能已经有所发展或是发生改变。
本人刚接触scrapy，主要看中了能暂停，继续，去查这几点，以前一直用requests或者requests-html,所以都是这样处理cookie的:
headers = {
'Accept-Language':'zh-CN',
'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36',
# dummy:
"cookie":"__cfduid=d2ea661e4cddec1eebedc2c54d78e6156698409;__utma=50351329.433346.1527221979.1527221979.1527221979.1;__utmc=501329;__utmz=501329.15271979.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none);__51cke__=;__51laig__=1;__tins__3878067=%7B%22sid%22%3A%201527221980323%2C%20%22vd%22%3A%201%2C%20%22expires%22%3A%201527223780323%7D;91username=regf3qc;CLIPSHARE=n9u906378onmf990kdlpq3;DUID=15fdcQq0vvU0U10%2FdVsdg5smxiBM18RO%2FQ5O3uuV%2F3pe;EMAILVERIFIED=no;language=cn_CN;level=1;remainclosed=1;user_level=1;USERNAME=1a9dkmjCzR6TueiJdjZzM6gIUE8AXAHzxIuxb4x6vEk;",
}
r = requests.get('http://example.com',headers=headers)
但是看scrapy文档的话是把cookie和header分开输入的，而且cookie还只能用 dict 输入。上面的cookie直接用EditThisCookie导出就可以了。cookie不是包含在了header里面了吗？在scrapy里这样写似乎也没用：
class PornSpider(scrapy.Spider):
name = 'pron'
def start_requests(self):
urls = ['http://pron.com/page={}'.format(i) for i in range(1,3)]
for url in urls:
yield Request(url,callback=self.parse,headers=headers) #这样似乎是没有用的, 返回的应该是不带 cookie 的页面
scrapy看起来比自己写方便很多，那想请教下能不能用requests库取代scrapy自带的Request呢？或者有没有更优雅的cookie导入方法呢？
谢谢大家

Resigned to fate.
