当蜘蛛完成抓取页面时，我试图在 gmail 中发送电子邮件..当我定义函数 send_mail 并像下面一样传递它时，在日志中，它说 send_mail("some message", "Scraper Report") NameError: name ' send_mail' 未定义..当蜘蛛完成抓取时我如何发送 gmail。当我在 def parse(self,response) 方法中传递 send_mail 函数时，由于抓取循环，它试图阻止我的 gmail..

如果他们在同一个班级，您需要添加self.发送邮件 ( )。self.send_mail(args)如果不是，那么您需要在定义函数后调用 send_mail() 。
