Java对接快递100实时快递单号查询API接口

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.URL;
import java.nio.charset.StandardCharsets;
 
public class Kd100Query {
    private static final String API_URL = "http://api.kd100.com:9600/api";
    private static final String API_KEY = "您的API_KEY"; // 快递100提供的API_KEY
 
    public static void main(String[] args) throws Exception {
        String expNo = "快递单号";
        String order = "查询方式"; // 如：orderid
 
        String param = "com=kd100&num=" + expNo + "&key=" + API_KEY + "&order=" + order;
        String result = sendPost(API_URL, param);
        System.out.println(result);
    }
 
    private static String sendPost(String urlStr, String param) throws Exception {
        URL url = new URL(urlStr);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoOutput(true);
        connection.setRequestMethod("POST");
        connection.setUseCaches(false);
        connection.setInstanceFollowRedirects(true);
        connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
 
        try (OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream(), StandardCharsets.UTF_8);
             BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream(), StandardCharsets.UTF_8))) {
            out.write(param);
            out.flush();
            StringBuilder sb = new StringBuilder();
            String line;
            while ((line = in.readLine()) != null) {
                sb.append(line);
            }
            return sb.toString();
        } finally {
            connection.disconnect();
        }
    }
}

这段代码使用了HttpURLConnection类发送POST请求到快递100的API接口，并将查询结果输出。需要替换API_KEY为您从快递100获取的API\_KEY，以及将expNo替换为要查询的快递单号。
