方式一：

public String updateRequest(String operation,String phone) {         String strResult = null;        HttpPost httpRequest =new HttpPost(CommonURL.UpdateURL);             List <NameValuePair> params=new ArrayList<NameValuePair>();             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("<body>(.*\r\n)*</body>");                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;    }
