    def __init__(self):
        self.base_url = "http://www.baidu.com/userid="
        self.uid_num = 1
        self.total_num = 10
 
    @every(minutes=24 * 60)
    def on_start(self):
        while self.uid_num <= self.total_num:
            url = self.base_url + str(self.uid_num)
            print url
            self.crawl(url, callback=self.index_page)
