package test;  
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 GetSample{  
  public static void main(String[] args) {  
  //构造HttpClient的实例  
  HttpClient httpClient = new HttpClient();  
  //创建GET方法的实例  
  GetMethod getMethod = new GetMethod("http://www.ibm.com");  
  //使用系统提供的默认的恢复策略  
  getMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,  
    new DefaultHttpMethodRetryHandler());  
  try {  
   //执行getMethod  
   int statusCode = httpClient.executeMethod(getMethod);  
   if (statusCode != HttpStatus.SC_OK) {  
    System.err.println("Method failed: "  
      + getMethod.getStatusLine());  
   }  
   //读取内容   
   byte[] responseBody = getMethod.getResponseBody();  
   //处理内容  
   System.out.println(new String(responseBody));  
  } catch (HttpException e) {  
   //发生致命的异常，可能是协议不对或者返回的内容有问题  
   System.out.println("Please check your provided http address!");  
   e.printStackTrace();  
  } catch (IOException e) {  
   //发生网络异常  
   e.printStackTrace();  
  } finally {  
   //释放连接  
   getMethod.releaseConnection();  
  }  
 }  
}
