其实这些东西好像不用这样获取的，中国天气网上直接提供有天气的json数据接口，

这里有篇文章是讲这些接口的http://blog.csdn.net/hytfly/article/details/20064479

不过最近想弄一个一键新闻或者其它例如糗百、微博热点、QQ热点聚合的东西。

先拿天气来练练手

其实这个不用模拟登陆，只需要一些简单的正则就可以，所以非常简单，上代码：

# -*- coding: utf-8 -*-import urllibimport reimport threadclass   Wathereather_Spider_Model:    def __init__(self):        self.ok = False    def getHtml(self,url):        page=urllib.urlopen(url)        html=page.read()        page.close()        return html    def getWeather(self,url):        html = self.getHtml(url)        reg='<dl><dt><a title=.*?>(.*?)</a></dt><dd><a href=.*?>.*?</a><a href=.*?><span>(.*?)</span></a>(.*?)<a href=.*?><b>(.*?)</b></a></dd></dl>'        self.weatherList=re.compile(reg).findall(html)        self.ok=True        #return weatherList    def start(self,pydaihao):        #http://www.weather.com.cn/html/province/beijing.shtml        url = "".join(["http://www.weather.com.cn/html/province/",pydaihao,".shtml"])        #print url        thread.start_new_thread(self.getWeather,(url,))        weatherModel = Wathereather_Spider_Model()pydaihao ="guangdong"weatherModel.start(pydaihao)print "now getting weather of ",pydaihaowhile True:    if weatherModel.ok:          for weather in weatherModel.weatherList:            print ""            for li in weather:                print str(li).decode('utf-8').encode('gb2312'),        weatherModel.ok=False        break

可以根据省份来获取天气

结果如下
