我有一个要从中抓取数据的URL列表。它来自我要更新的数据库,但不确定如何进行。
import scrapy
import sqlite3
from datetime import datetime, timedelta
class A1hrlaterSpider(scrapy.Spider):
name = 'onehrlater'
allowed_domains = ['donedeal.ie']
timenow = datetime.now()
delta = timedelta(minutes=0)
delta2 = timedelta(minutes=1)
past_time = timenow - delta
past_time2 = timenow - delta2
conn = sqlite3.connect('ddother.db')
c = conn.cursor()
c.execute("SELECT adUrl FROM database WHERE timestamp BETWEEN ? AND ?", (past_time2, past_time))
all_urls = c.fetchall()
urllist = [item[0] for item in all_urls]
print(urllist)
conn.commit()
conn.close()
网址列表是我要抓取的网址列表。但是我不确定如何使用start_urls来 请点击链接,或者如果确实是这样做的正确方法。我可以说start_urls = urllist还是这样?
任何帮助将不胜感激。谢谢
