例項HttpClient （使用代理）

需要引入的包：

commons-codec.jar

commons-httpclient.jar

commons-logging.jar

jericho-html.jar

import java.io.IOException; 
import org.apache.commons.httpclient.*; 
import org.apache.commons.httpclient.methods.GetMethod; 
import org.apache.commons.httpclient.params.HttpMethodParams; 
public class HttpClientTest{ 
   public static void main(String[] args) { 
   //HttpClient
   HttpClient httpClient = new HttpClient(); 
   //GET
    GetMethod getMethod = new GetMethod("http://blog.csdn.net/jackyren007"); 
   // 
    getMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, 
     new DefaultHttpMethodRetryHandler()); 
   try { 
    //getMethod 
    //int statusCode = httpClient.executeMethod(getMethod); 
    //proxy ip　×××.×××.×××.×××
    httpClient.getHostConfiguration().setProxy("×××.×××.×××.×××", 8080);
    int statusCode = httpClient.executeMethod(getMethod);
   
    if (statusCode != HttpStatus.SC_OK) { 
      System.err.println("Method failed: " 
        + getMethod.getStatusLine()); 
     } 
    //  InputStream
<script src="http://pagead2.googlesyndication.com/pagead/show_ads.js" type="text/javascript"></script>
    //InputStream responseBody = getMethod.getResponseBodyAsStream();
    //System.out.println(responseBody); 
    //byte
    //byte[] responseBody = getMethod.getResponseBody();
    //System.out.println(new String(responseBody));
    //string
    byte[] responseBody = getMethod.getResponseBody();
    String newresponseBody = new String(responseBody, "GBK");
    URI urll= getMethod.getURI();
    System.out.println(newresponseBody);
    System.out.println(urll);
    } catch (HttpException e) { 
    //
     System.out.println("Please check your provided http address!"); 
     e.printStackTrace(); 
    } catch (IOException e) { 
    //
     e.printStackTrace(); 
    } finally { 
    //
     getMethod.releaseConnection(); 
    } 
 } 
 }
