java使用HttpClient发送http请求

HttpResponse httpResponse=null;        HttpEntity httpEntity=null;        //生成一个请求对象 参数为请求的地址        HttpGet httpGet=new HttpGet("http://www.baidu.com");        //生成一个HttpClient客户端对象        HttpClient httpClient=new DefaultHttpClient();        InputStream inputStream=null;        try {             //使用http客户端发送请求对象到服务器             httpResponse=httpClient.execute(httpGet);             //包含服务器返回的内容             httpEntity=httpResponse.getEntity();             //从流中服出内容             inputStream=httpEntity.getContent();             BufferedReader bufferedReader=new BufferedReader(new InputStreamReader(inputStream));             String result="";             String line="";             while((line=bufferedReader.readLine())!=null){                 result+=line;             }             System.out.println(result);        } catch (Exception e) {            e.printStackTrace();        }finally{            try {                if(inputStream!=null){                    inputStream.close();                }            } catch (Exception e2) {                e2.printStackTrace();            }        }
