如何将多个参数传递给Scrapy spider(不再支持使用多个蜘蛛运行'scrapy crawl'错误)？

Question

我想将多个用户定义的参数传递给我的scrapy spyder,所以我试着关注这篇文章:如何在scrapy spider中传递用户定义的参数

但是,当我按照建议在那里时,我收到一个错误:

root@ scrapy crawl dmoz -a address= 40-18 48th st -a borough=4
Usage
=====
  scrapy crawl [options] <spider>

crawl: error: running 'scrapy crawl' with more than one spider is no longer supported

我也试过各种引号的排列:

root@ scrapy crawl dmoz -a address= "40-18 48th st" -a borough="4"
Usage
=====
  scrapy crawl [options] <spider>
crawl: error: running 'scrapy crawl' with more than one spider is no longer supported

将参数传递给Scrapy蜘蛛的正确方法是什么？我想传递蜘蛛登录/抓取过程的用户名和密码.谢谢你的任何建议.

没scrapy问题,我想.这是你shell解释输入的方式,在空格中分割标记.因此,您不能在密钥及其值之间使用任何密钥.试试:

scrapy crawl dmoz -a address="40-18 48th st" -a borough="4"
