我们知道,如果要在命令行下面运行一个 Scrapy 爬虫,一般这样输入命令: scrapy crawl xxx 此时,这个命令行窗口在爬虫结束之前,会一直有数据流动,无法再输入新的命令。...我们也知道,可以通过两条Python 代码,在 Python 里面运行 Scrapy 爬虫: from scrapy.cmdline import execute execute('scrapy crawl...get_project_settings settings = get_project_settings() crawler = CrawlerProcess(settings) crawler.crawl...('爬虫名1') crawler.crawl('爬虫名2') crawler.crawl('爬虫名3') crawler.start() 使用这种方法,可以在同一个进程里面跑多个爬虫。...('exercise') crawler.crawl('ua') crawler.start() crawler.start() 运行效果如下图所示: ?
