安卓与后台进行数据交互

方式一：

public String updateRequest(String operation,String phone) { 
        String strResult = null;
        HttpPost httpRequest =new HttpPost(CommonURL.UpdateURL);     
        List  params=new ArrayList();     
        params.add(new BasicNameValuePair("Operation",operation));  
        params.add(new BasicNameValuePair("Phone",phone)); 
        try{  
            httpRequest.setEntity(new UrlEncodedFormEntity(params,HTTP.UTF_8));
            HttpResponse httpResponse=new DefaultHttpClient().execute(httpRequest);
            if(httpResponse.getStatusLine().getStatusCode()==200){     
                //取出回应字串
                strResult=EntityUtils.toString(httpResponse.getEntity()); 
                Pattern titleP = Pattern.compile("(.*\r\n)*");
                Matcher matchedTitle = titleP.matcher(strResult);
                Boolean foundTitle = matchedTitle.find();
                if(foundTitle){
                    strResult = matchedTitle.group(1);
                }

            }else{     
                Log.e("请求结果：", "请求失败！");  
            }     
        }catch(ClientProtocolException e){     

            e.printStackTrace();     
        } catch (UnsupportedEncodingException e) {     

            e.printStackTrace();     
        } catch (IOException e) {     
            e.printStackTrace();     
        } 

        return strResult;
    }

方式二：

public String sendRequest(JSONObject object,String MyURL) {
        String jsonStr=null;
        try {  
            URL url = new URL(MyURL);  
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();  
            conn.setRequestMethod("POST");  
            conn.setRequestProperty("ser-Agent", "Fiddler");  
            conn.setRequestProperty("Content-Type", "application/json");  
            conn.setConnectTimeout(5 * 1000); 
            // 包装并上传数据  
            OutputStream outputStream = conn.getOutputStream();  
            outputStream.write(URLEncoder.encode(object.toString(), "UTF-8").getBytes());  

            // 如果请求响应码是200，则表示成功  
            if (conn.getResponseCode() == HttpURLConnection.HTTP_OK) {  

                //获取服务器上的数据  
                BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream(), "utf-8"));  
                //解码  
                jsonStr = URLDecoder.decode(in.readLine(), "UTF-8");  
                in.close();  
                conn.disconnect();  
            }  
        } catch (MalformedURLException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        } catch (ProtocolException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        }catch (SocketTimeoutException e) { 
            jsonStr = "连接超时";

        }catch (IOException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        }

        return jsonStr;

    }
