思路构建
1.先通过本地的测IP地址库进行匹配
2.如果本地IP地址库存在此IP的城市信息，就直接返回，调用速度也快
3.如果本地没有对应的IP城市信息，必须通过调用网络的IP查询的API了，这里我使用了（百度，新浪，和淘宝）
注意：百度的调用不是很正常，大批量调用
要引用dll Newtonsoft.Json.dll 下载地址：http://www.newtonsoft.com/products/json/ 1.解压下载文件,得到Newtonsoft.Json.dll 2.在项目中添加引用..3.兼容.net framwork2.0到4.5框架
使用NewtonSoft.JSON.dll来序列化和发序列化对象

调用方式：
