python 获取省份的天气预报

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，

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，所以非常简单，上代码：

# -*- coding: utf-8 -*-
import urllib
import re
import thread
class   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 ",pydaihao
while 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

结果如下
