调用：

        //string ip = JsonData.GetIp();

        //JArray jarry = JArray.Parse("[" + ip + "]");
        //SYS_LoginInfo loginInfo;
      
        //    loginInfo = new SYS_LoginInfo
        //    {
        //        SYS_LoginTime = Convert.ToInt32(JsonData.time),                               //登陆时间
        //        SYS_IP = jarry[0]["result"]["ip"].ToString(),                    //ip 
        //        SYS_city = jarry[0]["result"]["ad_info"]["city"].ToString(),      // 城市
        //        SYS_district = jarry[0]["result"]["ad_info"]["district"].ToString(),  //地区
        //        SYS_nation = jarry[0]["result"]["ad_info"]["nation"].ToString(),   // 国家
        //        SYS_province = jarry[0]["result"]["ad_info"]["province"].ToString()  //省份
        //    }

然后执行
string sql = "insert dataimg(imgdata,SYS_LoginTime,SYS_IP,SYS_city,SYS_district,SYS_nation,SYS_province) values(@imgdata,@SYS_LoginTime,@SYS_IP,@SYS_city,@SYS_district,@SYS_nation,@SYS_province)";
SqlParameter imgdata = new SqlParameter("@imgdata", loginInfo.info == null ? "" : loginInfo.info);
SqlParameter SYS_LoginTime = new SqlParameter("@SYS_LoginTime", Convert.ToInt32(JsonData.time)); ///时间
SqlParameter SYS_IP = new SqlParameter("@SYS_IP", "");
SqlParameter SYS_city = new SqlParameter("@SYS_city", loginInfo.SYS_city==null?"": loginInfo.SYS_city);
SqlParameter SYS_district = new SqlParameter("@SYS_district", loginInfo.SYS_district == null ? "" : loginInfo.SYS_district);
SqlParameter SYS_nation = new SqlParameter("@SYS_nation", loginInfo.SYS_nation == null ? "" : loginInfo.SYS_nation);
SqlParameter SYS_province = new SqlParameter("@SYS_province", loginInfo.SYS_province == null ? "" : loginInfo.SYS_province);
SqlCommand cmd = new SqlCommand(sql, conn);
conn.Open();

        cmd.Parameters.Add(imgdata);
        cmd.Parameters.Add(SYS_LoginTime);
        cmd.Parameters.Add(SYS_IP);
        cmd.Parameters.Add(SYS_city);
        cmd.Parameters.Add(SYS_district);
        cmd.Parameters.Add(SYS_nation);
        cmd.Parameters.Add(SYS_province);
        int count = cmd.ExecuteNonQuery();
        conn.Close();
        return count;

插入到数据 库 就变成 服务器ip地址了

@Cgrain: 上面的代码中并没有获取客户端 IP 地址的代码，比如

var ip = Request.UserHostAddress;

@dudu: 我这样掉是不行嘛
public static string GetIp() {
return HttpGet("https://apis.map.qq.com/ws/location/v1/ip?key=3BFBZ-ZKD3X-LW54A-ZT76D-E7AHO-4RBD5");

有点蒙~~~

@Cgrain: 这是服务器自己请求 apis.map.qq.com ，得到的是服务器自己的 IP 地址

@dudu: var ip = Request.UserHostAddress; 这样就是获取客户端的嘛？

@Cgrain: 是的

@dudu: 还有这个省市区 怎么获取

@Cgrain:

var ip = Request.UserHostAddress;
var result = HttpGet("https://apis.map.qq.com/ws/location/v1/ip?ip=" + ip + "&key=3BFBZ-ZKD3X-LW54A-ZT76D-E7AHO-4RBD5"

@dudu: 还可以这样.... 谢谢大佬！！！
