python从淘宝ip库中获取公网ip的信息
看到一个题目: 从ip.taobao.com中获取公网ip的信息
分析:
1、生成公网IP地址;
2、根据ip.taobao.com返回的代码,用json解析 下面是淘宝的接口说明

接口说明
1. 请求接口(GET):
http://ip.taobao.com/service/getIpInfo.php?ip=[ip地址字串]
2. 响应信息:
(json格式的)国家 、省(自治区或直辖市)、市(县)、运营商
3. 返回数据格式:
{"code":0,"data":{"ip":"210.75.225.254","country":"\u4e2d\u56fd","area":"\u534e\u5317",
"region":"\u5317\u4eac\u5e02","city":"\u5317\u4eac\u5e02","county":"","isp":"\u7535\u4fe1",
"country_id":"86","area_id":"100000","region_id":"110000","city_id":"110000",
"county_id":"-1","isp_id":"100017"}}
其中code的值的含义为,0:成功,1:失败。

但是运行中会报错,
