java调用淘宝api联网查询ip归属地

2019年07月22日  | 移动技术网IT编程  | 我要评论

淘宝返回的数据为：
{"code":0,"data":{"country":"\u4e2d\u56fd","country_id":"cn","area":"\u534e\u4e1c","area_id":"300000","region":"\u5c71\u4e1c\u7701","region_id":"370000","city":"\u4e1c\u8425\u5e02","city_id":"370500","county":"","county_id":"-1","isp":"\u8054\u901a","isp_id":"100026","ip":"60.214.183.158"}}

用法：

复制代码 代码如下:

string arr1 = getaddressbyip.getaddressbyip("120.192.182.1");
system.out.println(arr1);


详细请看代码

复制代码 代码如下:

package getaddressbyip;

import java.io.bytearrayoutputstream;
import java.io.ioexception;
import java.io.inputstream;
import java.net.httpurlconnection;
import java.net.malformedurlexception;
import java.net.url;

import net.sf.json.jsonobject;

public class getaddressbyip
{

 
 /**
  *
  * @param ip
  * @return
  */
 public static string getaddressbyip(string ip){
  string resout = "";
  try{
   string str = getjsoncontent("http://ip.taobao.com/service/getipinfo.php?ip="+ip);
   system.out.println(str);

   jsonobject obj = jsonobject.fromobject(str);
   jsonobject obj2 =  (jsonobject) obj.get("data");
   string code = (string) obj.get("code");
   if(code.equals("0")){

    resout =  obj2.get("country")+"--" +obj2.get("area")+"--" +obj2.get("city")+"--" +obj2.get("isp");
   }else{
    resout =  "ip地址有误";
   }
  }catch(exception e){

   e.printstacktrace();
    resout = "获取ip地址异常："+e.getmessage();
  }
  return resout;

 }

    public static string getjsoncontent(string urlstr)
    {
        try
        {// 获取httpurlconnection连接对象
            url url = new url(urlstr);
            httpurlconnection httpconn = (httpurlconnection) url
                    .openconnection();
            // 设置连接属性
            httpconn.setconnecttimeout(3000);
            httpconn.setdoinput(true);
            httpconn.setrequestmethod("get");
            // 获取相应码
            int respcode = httpconn.getresponsecode();
            if (respcode == 200)
            {
                return convertstream2json(httpconn.getinputstream());
            }
        }
        catch (malformedurlexception e)
        {
            e.printstacktrace();
        }
        catch (ioexception e)
        {
            e.printstacktrace();
        }
        return "";
    }
    private static string convertstream2json(inputstream inputstream)
    {
        string jsonstr = "";
        // bytearrayoutputstream相当于内存输出流
        bytearrayoutputstream out = new bytearrayoutputstream();
        byte[] buffer = new byte[1024];
        int len = 0;
        // 将输入流转移到内存输出流中
        try
        {
            while ((len = inputstream.read(buffer, 0, buffer.length)) != -1)
            {
                out.write(buffer, 0, len);
            }
            // 将内存流转换为字符串
            jsonstr = new string(out.tobytearray());
        }
        catch (ioexception e)
        {
            // todo auto-generated catch block
            e.printstacktrace();
        }
        return jsonstr;
    }
}
