使用Apache的HttpClient包

import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStream;import org.apache.http.HttpEntity;import org.apache.http.client.ClientProtocolException;import org.apache.http.client.methods.CloseableHttpResponse;import org.apache.http.client.methods.HttpGet;import org.apache.http.impl.client.CloseableHttpClient;import org.apache.http.impl.client.HttpClients;import org.apache.http.util.EntityUtils;public class HttpTest { public static void main(String[] args) throws ClientProtocolException, IOException      {   CloseableHttpClient httpclient = HttpClients.createDefault();         try {            HttpGet httpGet = new HttpGet("http://img2.126.net/xoimages/8/20141101/x/640x100.jpg");            CloseableHttpResponse response = httpclient.execute(httpGet);            try {                HttpEntity entity = response.getEntity();                InputStream inStream = entity.getContent();                FileOutputStream fw = new FileOutputStream("C:/Users/MIAO/Desktop/Response.jpg", false);    int b = inStream.read();    while (b != -1) {    fw.write(b);    b = inStream.read();    }                fw.close();                EntityUtils.consume(entity);            } finally {                response.close();            }        }finally {            httpclient.close();        }    } }
