借助第三方，java长链接转短链接，IP域名同样支持

短信和微博中用到短链接，短链接的主要职责就是把原始链接很长的地址压缩成短链接地址，当点击这个链接后，又可以跳转到原始链接地址。

package common.util;
import java.util.ArrayList;
import java.util.List;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;

/**
 * TODO(工具类：借助第三方，将长连接转换为短连接)
 * 

 *
 */
public class ShortUrlUtil {

	public static DefaultHttpClient httpclient;
	static {
		httpclient = new DefaultHttpClient();
	}

	/**
	 * 生成短连接信息
	 */
	public static String generateShortUrl(String url) {

		try {
			HttpPost httpost = new HttpPost("http://suo.im/api.php");
			List params = new ArrayList();
			params.add(new BasicNameValuePair("format", "utf-8")); // 编码
			params.add(new BasicNameValuePair("url", url)); // 用户名称
			httpost.setEntity(new UrlEncodedFormEntity(params, "utf-8"));
			HttpResponse response = httpclient.execute(httpost);
			String jsonStr = EntityUtils.toString(response.getEntity(), "utf-8");
			return jsonStr;
		} catch (Exception e) {
			e.printStackTrace();
			return "Error";
		}

	}

	/**
	 * 测试生成短连接
	 */
	public static void main(String[] args) {
		String url = generateShortUrl("http://192.168.1.88:8080/admin/login.html");
		System.out.println(url);
	}

}

利用第三方接口生成短链接

缩短网址http://suo.im/ 除了提供在线生成外，还提供了API接口调用。
