python - The webpage cannot be crawled again after updating the data

Question

The webpage I crawled updated a piece of information today, and then the crawler ran but did not crawl it.

from pyspider.libs.base_handler import *
from pyspider.database.mysql.mysqldb import SQL

class Handler(BaseHandler):
    crawl_config = {
    }
       
    @every(minutes=24 * 60)
    def on_start(self):
        self.crawl('http://www.yxztb.net/yxweb/zypd/012001/012001001/', callback=self.index_page)

    @config(age=10 * 24 * 60 * 60)
    def index_page(self, response):
        for each in response.doc('.tdmoreinfosub a').items():
            self.crawl(each.attr.href, callback=self.detail_page)
            
    @config(priority=2)
    def detail_page(self, response):
        
        return {
                "address":"宜兴市",
                "url":response.url,
                "title":response.doc('font  span').text(),
                "date" :response.doc('#tdTitle > .webfont').text()[8:17],
            }
    
    def on_result(self, result):
        print result
        if not result or not result['title']:
            return
        sql = SQL()
        sql.replace('zhaobiao',**result)
 

    

I hope the bosses can be more specific and have more exchanges

Answer 1

@config (age) parameter setting directly ignores the execution of index.page

Answer 2

Since @every of on_start is one day, then set age=12 * 60 * 60 半天是比较合适的，保证每次 every 肯定不会被 age 所限制。另外 @config(age=10 * 24 * 60 * 60) in self.crawl, which means not to crawl again within 10 days.
