最近小弟在做快递查询类的网站，需要用手机查，于是就从各大快递网站偷来了API接口代码。独乐乐不如众乐乐，在这里分享一下：

package com.kuaidi.openapi;
import
import
import
import
import java.util.List;
import java.util.Map;

public class Openapi {

    private String app_key = "";

    private String api_url = "http://api.

    private String show = "0";

    private String muti = "0";

    private String order = "desc";

    /**
     * 您获得的快递网接口查询KEY。
     *
     * @param app_key
     *
     */
    public void setApp_key(String app_key) {
        this.app_key = app_key;
    }

    /**
     * 设置数据返回类型。0: 返回 json 字符串; 1:返回 xml 对象
     *
     * @param show
     *
     */
    public void setShow(String show) {
        this.show = show;
    }

    /**
     * 设置返回物流信息条目数, 0:返回多行完整的信息; 1:只返回一行信息
     *
     * @param muti
     *
     */
    public void setMuti(String muti) {
        this.muti = muti;
    }

    /**
     * 设置返回物流信息排序。desc:按时间由新到旧排列; asc:按时间由旧到新排列
     *
     * @param order
     *
     */
    public void setOrder(String order) {
        this.order = order;
    }

    /**
     *
     * @param nu
     * @param exname
     * @return result
     */
    public String query(String nu, String exname) {
        String sign = "id=" + app_key + "&com=" + exname + "&nu=" + nu + "&show=" + show + "&muti=" + muti + "&order="
                + order;
        String result = sendGet(api_url + sign);
        return result;
    }

    /**
     * 向指定URL发送GET方法的请求
     *
     * @param url
     *            发送请求的URL
     * @return URL 所代表远程资源的响应结果
     */
    private static String sendGet(String url) {
        String result = "";
        BufferedReader in = null;
        try {
            URL realUrl = new URL(url);
            // 打开和URL之间的连接
            URLConnection connection = realUrl.openConnection();
            // 设置通用的请求属性
            connection.setRequestProperty("accept", "*/*");
            connection.setRequestProperty("connection", "Keep-Alive");
            connection.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
            // 建立实际的连接
            connection.connect();

            // 定义 BufferedReader输入流来读取URL的响应
            in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            while ((line = in.readLine()) != null) {
                result += line;
            }
        } catch (Exception e) {
            System.out.println("发送GET请求出现异常！" + e);
            e.printStackTrace();
        }
        // 使用finally块来关闭输入流
        finally {
            try {
                if (in != null) {
                    in.close();
                }
            } catch (Exception e2) {
                e2.printStackTrace();
            }
        }
        return result;
    }
}







1.例子：
package com.kuaidi.openapi;

public class OpenapiExample {
   
    private static String key="************";//官网申请的key

    public static void main(String[] args){
        Openapi o = new Openapi();
        o.setApp_key(key);
        String result =o.query("111111", "quanfengkuaidi");
        System.out.println(result);
    }
}
