• 【转载】Android HttpClient基本使用方法


    这里只介绍如何使用HttpClient发起GET或者POST请求

    GET 方式

    //先将参数放入List,再对参数进行URL编码
    List<BasicNameValuePair> params = new LinkedList<BasicNameValuePair>();
    params.add(new BasicNameValuePair("param1", "中国"));
    params.add(new BasicNameValuePair("param2", "value2"));
    
    //对参数编码
    String param = URLEncodedUtils.format(params, "UTF-8");
    
    //baseUrl            
    String baseUrl = "http://ubs.free4lab.com/php/method.php";
    
    //将URL与参数拼接
    HttpGet getMethod = new HttpGet(baseUrl + "?" + param);
                
    HttpClient httpClient = new DefaultHttpClient();
    
    try {
        HttpResponse response = httpClient.execute(getMethod); //发起GET请求
    
        Log.i(TAG, "resCode = " + response.getStatusLine().getStatusCode()); //获取响应码
        Log.i(TAG, "result = " + EntityUtils.toString(response.getEntity(), "utf-8"));//获取服务器响应内容
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    POST方式

    //和GET方式一样,先将参数放入List
    params = new LinkedList<BasicNameValuePair>();
    params.add(new BasicNameValuePair("param1", "Post方法"));
    params.add(new BasicNameValuePair("param2", "第二个参数"));
                
    try {
        HttpPost postMethod = new HttpPost(baseUrl);
        postMethod.setEntity(new UrlEncodedFormEntity(params, "utf-8")); //将参数填入POST Entity中
                    
        HttpResponse response = httpClient.execute(postMethod); //执行POST方法
        Log.i(TAG, "resCode = " + response.getStatusLine().getStatusCode()); //获取响应码
        Log.i(TAG, "result = " + EntityUtils.toString(response.getEntity(), "utf-8")); //获取响应内容
                    
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
