Question

我尝试使用以下命令恢复我执行的爬行（后来尝试恢复）：

scrapy crawl somespider -s JOBDIR=crawls/somespider-1

但它没有恢复，而是显示以下日志输出：

这是我的蜘蛛代码（如果我没有记错的话，这些请求对我来说是可序列化的）。设置：http://pastebin.com/CUsf4sTJ 蜘蛛：http://pastebin.com/at98Qhjh

我做错了什么？我能以任何方式挽救爬行吗？

Answer 1

您继承自BaseSpider，只抓取start_urls。你应该继承CrawlSpider（scrapy.contrib.spiders.CrawlSpider）。

为什么我无法在Scrapy中恢复爬行？
