yahoo重新开放了天气api，不使用oauth只能每天获取2000次/ip
使用oauth获取天气的python代码如下，使用了requests_oauthlib进行认证
使用oauth获取天气的次数为每小时2w次，每天10w次。
使用前请注册一个Yahoo的APP获得key
# sudo pip install requests requests_oauthlib
import requests from requests_oauthlib import OAuth1 consumerKey =consumerSecret = baseurl = "https://query.yahooapis.com/v1/yql?" yql_query = 'select * ' + 'from weather.forecast where woeid in' yql_query += ' (select woeid from geo.places(1) where text="%s") and u="c"' % "Beijing" auth = OAuth1(consumerKey, consumerSecret) result = requests.post(baseurl, data={'q': yql_query, 'format': 'json'}, auth=auth) print result # Out[10]: print result.json()
# Out[11]: u'{"query":{"count":1,"created":"2017-07-10T12:50:30Z","lang":"en-US","results":{"channel":{"units":{"distance":"km","pressure":"mb","speed":"km/h","temperature":"C"},"title":"Yahoo!
