Scrapy順序執行多個爬蟲 有兩種方式：

第一種：bat方式運行

????????新建bat文件?

cd C:\python_web\spiders\tiktokSelenium & C: & scrapy crawl spider1 & scrapy crawl spider2 & scrapy crawl spider3 & scrapy crawl spider4

第二種：

使用subprocess按照順序執行多個爬蟲，新建一個start.py文件，輸入一下內容，

def crawl_work():subprocess.Popen('scrapy crawl spider1', shell=True).wait()subprocess.Popen('scrapy crawl spider2', shell=True).wait()subprocess.Popen('scrapy crawl spider3', shell=True).wait()subprocess.Popen('scrapy crawl spider4', shell=True).wait()
if __name__ == '__main__':crawl_work()

然后?

cd C:\python_web\spiders\tiktokSelenium & C: & python ./start.py
