本文介绍了一种利用Java中的HttpClient库来实现长网址到短网址转换的方法。通过具体代码示例，展示了如何发送POST请求并将长网址缩短为短网址的过程。

直接贴代码吧，依赖包有apache的httpclient，可以在apache.org下http components下下载（这个包需要apache的commons logging的包才能运行，囧！）

package net.test.aaron;

import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
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;

public class ShortUrlTest {

	/**
	 * @param args
	 * @throws IOException 
	 * @throws ClientProtocolException 
	 */
	public static void main(String[] args) throws ClientProtocolException, IOException {
		List<NameValuePair> formparams = new ArrayList<NameValuePair>();
		formparams.add(new BasicNameValuePair("url", "http://www.udrop.net/s/0/4/4/1S1lCnwx17AP17KPC6-M1S16yA==?m=1367116329454"));
		UrlEncodedFormEntity reqentity = new UrlEncodedFormEntity(formparams, "UTF-8");
		
		HttpPost httppost = new HttpPost("http://dwz.cn/create.php?url=");
		
		HttpClient httpclient = new DefaultHttpClient();
		httppost.setEntity(reqentity);
		HttpResponse response = httpclient.execute(httppost);
		HttpEntity respentity = response.getEntity();
		if (respentity != null) {
		    /*if (len != -1 && len < 2048) {
		        System.out.println(EntityUtils.toString(entity));
		    } else {
		        // Stream content out
		    }*/
			InputStream instream = null;
		    try {
		        // do something useful
			    //instream = entity.getContent();
		        System.out.println(EntityUtils.toString(respentity, "UTF-8"));
			    //long len = entity.getContentLength();
		    } finally {
		        //instream.close();
		    }
		}
	}

}

有个问题，我在测试环境下，host是一个内网IP加上一个端口号，会提示这个URL不安全，返回错误！
