• 在spiders同級創建任意目錄，如：commands
• 在其中創建 crawlall.py 文件 （此處文件名就是自定義的命令）

from scrapy.commands import ScrapyCommand
    from scrapy.utils.project import get_project_settings


    class Command(ScrapyCommand):

        requires_project = True

        def syntax(self):
            return ‘[options]‘

        def
 
 short_desc(self):
            return ‘Runs all of the spiders‘

        def run(self, args, opts):
            spider_list = self.crawler_process.spiders.list()
            for name in spider_list:
                self.crawler_process.crawl(name, **opts.__dict__)
            self.crawler_process.start()

crawlall.py
 

• 在settings.py 中添加配置 COMMANDS_MODULE = ‘項目名稱.目錄名稱‘
• 在項目目錄執行命令：scrapy crawlall
