java通过http调用服务

package test;

import org.apache.commons.httpclient.methods.GetMethod;

public class TestHttpclient {

    public static void main(String[] args) throws HttpException, IOException {
        // TODO Auto-generated method stub
        HttpClient httpclient=new HttpClient();//创建一个客户端，类似打开一个浏览器  
        GetMethod getMethod=new GetMethod("http://www.baidu.com");//创建一个get方法，类似在浏览器地址栏中输入一个地址  
        int statusCode=httpclient.executeMethod(getMethod);//回车——出拳！  
        System.out.println("response=" + getMethod.getResponseBodyAsString());//察看拳头命中情况，可以获得的东西还有很多，比如head, cookies等等  
        getMethod.releaseConnection();//释放，记得收拳哦 
        
//        Cookie[] cookies = httpclient.getState().getCookies();  
//        System.out.println("Present cookies: ");  
//        for (int i = 0; i < cookies.length; i++) {//循环结构零部件  
//            System.out.println(" - " + cookies[i].toExternalForm());  
//            System.out.println(" - domain=" + cookies[i].getDomain());  
//            System.out.println(" - path=" + cookies[i].getPath());
