import requests
from lxml import html

headers = {'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 UBrowser/6.2.4094.1 Safari/537.36'}

try:
        
    rep = requests.get(url, headers = headers, timeout = 5)
    time.sleep(1)
    if rep.status_code == 200:
        print("链接成功")
        con = rep.content
        sel = html.fromstring(con)
        date = sel.xpath('//div[@class="texttit_m1"]/p/text()')
        date = str(date).replace(']', '').replace('[', '').replace("'", '').replace(u'\u3000', '')
        print(date)
