問(wèn)題描述

Scrapy爬蟲(chóng)時(shí)，由于重定向或是其他原因，會(huì)導(dǎo)致原始的start_url發(fā)生改變，怎樣才能得到原始的start_url?

def start_requests(self): start_url = ’your_scrapy_start_url’ yield Request(start_url, self.parse) def parse(self, response): item = YourItem() item[’start_url’] = 原始請(qǐng)求的start_url yield item

問(wèn)題解答

參考文章：Scrapy爬蟲(chóng)常見(jiàn)問(wèn)題總結(jié)

利用Request中的meta參數(shù)傳遞信息

def start_requests(self): start_url = ’your_scrapy_start_url’ yield Request(start_url, self.parse, meta={’start_url’:start_url}) def parse(self, response): item = YourItem() item[’start_url’] = response.meta[’start_url’] yield item
