  • 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();  
    }
