Python调用Ip138获取IP地址信息例子

def ip():
    url = "http://1111.ip138.com/ic.asp"
    code = urllib2.urlopen(url).read()
    ip = re.search('＼d+＼.＼d+＼.+＼d+＼.＼d+',code).group()
    print u'IP地址是：',ip
    address(ip)

def address(ip):
    url = "http://www.ip138.com/ips138.asp?ip=%s" % ip
    key = re.compile(r'.*<li>(.*)</li><li>(.*)</li>.*')
    code = urllib2.urlopen(url).read()
    address = key.search(code).group()
    print key.sub(r'＼1＼n＼2',address).decode('gbk')

ip()

class ip138:
    '处理关于url获取后的一些字符查找替换工作'
 
    def __init__(self,ip):
        self.ip = ip

        lines = self.__open()
        for line in lines :
            if '<ul class="ul1">'  in line:
                return p.sub(r'＼1＼n＼2',line).decode('gbk')
 
ip = sys.argv[1]
 
if __name__ == '__main__':
    m = ip138(ip)
    print "查询的ip: %s＼n%s" %(ip, m.get().encode('utf-8')),
