def getid():
global page
pages = requests.get('http://www.huodongxing.com/events?orderby=o&city=%E5%85%A8%E9%83%A8&page=' + str(page))
page = int(page) + 1
soup = BeautifulSoup(pages.text, 'html.parser')
res = soup.find_all("div",class_="search-tab-content-item-mesh") #查找所有class
for item in res: #循环res结果集
txtlist = item.find('a')  #找到第一个a标签
print(txtlist['href']) #打印a标签href值
time.sleep(5)
