1：获取ip，在django的request中META里面：

if request.META.has_key('HTTP_X_FORWARDED_FOR'):  
    ip =  request.META['HTTP_X_FORWARDED_FOR']  
else:  
    ip = request.META['REMOTE_ADDR']

2：获取具体ip所在地址：

url = "http://ip.taobao.com/service/getIpInfo.php?ip="
data = json.loads(urllib.urlopen(url + ip).read())
for oneinfo in datadict:
    if "code" == oneinfo:
        if datadict[oneinfo] == 0:
            return datadict["data"]["country"] + datadict["data"]["region"] + datadict["data"]["city"]
