如何每天定时更新爬虫数据

编写一个脚本,将改脚本放置 爬虫项目 同级目录下

    具体代码如下

import datetime
import time
from scrapy import cmdline
def spider():
    # 把爬虫程序放在这个类里 zhilian_spider 是爬虫的name
    cmdline.execute('scrapy crawl zhilian_spider'.split())
# 想几点更新,定时到几点
def main(h=17, m=54):
    while True:
        now = datetime.datetime.now()
        # print(now.hour, now.minute)
        if now.hour == h and now.minute == m:
            spider()
        # 每隔60秒检测一次
        time.sleep(60)
if __name__ == '__main__':
    main()
