使用requests和BeautifulSoup爬取天气信息。
这是从不倒翁问答系统的祖传代码里翻出来的，利用搜狗搜索获取天气信息，开箱即用。
代码语言：javascript复制from bs4 import BeautifulSoup
import requests
headers = {'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36'}
def AskSogouWeather(q):
url = 'https://www.sogou.com/web?query=%s' % q
resp = requests.get(url, timeout=5, headers=headers)
soup = BeautifulSoup(resp.text, 'html.parser')
rlst = soup.find('div', 'vr-weather161227')
if rlst is None: return None
md = rlst.find('div', 'more-day')
if md is None: return None
items = md.find_all('a')
item = None
today = items[0]
for it in items:
xxs = it.get('queryinfo', '').split(';')
xxs = [x for x in xxs if x != '']
if '今天' in xxs: today = it
for xx in xxs:
if xx in q:
item = it
if item is None: item = today
res = item.text.replace('xa0', ' ').replace("n"," ").strip().replace(' ', ' ')
return res
def WeatherRule(q):
if '天气' in q and ('怎' in q or '如何' in q):
res = AskSogouWeather(q)
return res
if __name__ == '__main__':
print(WeatherRule('明天天气怎么样'))
