获取考试类型和分类蜘蛛命令:

scrapy crawl koolearn_tiku_cate

获取分类和章蜘蛛命令:

scrapy crawl koolearn_tiku_chpater

获取题目蜘蛛命令:

scrapy crawl koolearn_tiku_question

说明:例如获取题目可能数量较多,耗时久,可以暂停或者恢复爬虫

要启用一个爬虫的持久化，运行以下命令:

scrapy crawl koolearn_tiku_cate -s JOBDIR=crawls/koolearn_tiku_question-1
然后，你就能在任何时候安全地停止爬虫(按Ctrl-C或者发送一个信号)。恢复这个爬虫也是同样的命令:

scrapy crawl koolearn_tiku_cate -s JOBDIR=crawls/koolearn_tiku_question-1
