HttpClient的使用方法案例

HttpClient 是 Apache Jakarta Common 下的子项目，可以用来提供高效的、最新的、功能丰富的支持 HTTP 协议的客户端编程工具包，并且它支持 HTTP 协议最新的版本和建议。

以下是我写的一个httpclient的测试程序，供大家参考：

package crawlerTest;

import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.HttpVersion;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicHttpResponse;
import org.apache.http.util.EntityUtils;
public class httpTest {
  public static void main(String[] args) throws IOException {
  	HttpClient client = new DefaultHttpClient();   //初始化httpclient
  	String personalUrl="http://www.autohome.com.cn/beijing/";         //指定一个种子url
  	HttpGet postMethod = new HttpGet(personalUrl);   //post方法请求
  	System.out.println("postMethod====="+ postMethod+"=====");
  	    (personalUrl);		
  	System.out.println(+getMethod+);
  	    (HttpVersion.HTTP_1_1,
  			HttpStatus.SC_OK, );                        
  	response = client.execute(getMethod);	                
  	System.out.println(+response+);
  	   response.getStatusLine().getStatusCode(); 
  	System.out.println(+StatusCode+);
  	System.out.println(response);
  	(StatusCode == ){                          
  		
  		   EntityUtils.toString (response.getEntity(),);
  		
  		System.out.println(entity);
  		EntityUtils.consume(response.getEntity());       
  	} {
  		
  		EntityUtils.consume(response.getEntity());        
  	}
  }

}
