百度短网址api java_Java调用百度短网址生成短链接

好的，你可以使用百度短网址的API来生成短链接。以下是Java代码示例：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;

public class BaiduShortUrl {
    public static void main(String[] args) {
        String longUrl = "http://www.baidu.com"; // 待转换的长链接
        String apiKey = "你的API Key"; // 填写你在百度短网址申请的API Key

        String url = "http://dwz.cn/create.php";
        String param = "url=" + URLEncoder.encode(longUrl, "UTF-8") + "&apikey=" + apiKey;

        String result = sendGet(url, param);
        System.out.println(result);
    }

    private static String sendGet(String url, String param) {
        String result = "";
        BufferedReader in = null;

        try {
            String urlNameString = url + "?" + param;
            URL realUrl = new URL(urlNameString);
            HttpURLConnection connection = (HttpURLConnection) realUrl.openConnection();
            connection.setRequestMethod("GET");
            connection.connect();

            in = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
            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();
        } finally {
            try {
                if (in != null) {
                    in.close();
                }
            } catch (Exception e2) {
                e2.printStackTrace();
            }
        }

        return result;
    }
}

在上面的代码中，你需要替换 `longUrl` 和 `apiKey` 的值。`longUrl` 是你要转换成短链接的长链接，`apiKey` 是你在百度短网址申请的API Key。运行代码后，你将会得到一个 JSON 格式的响应，其中包含了生成的短链接。
