服务器端如何提取客户端POST的数据

GET 和 POST 有什么区别？ GET 和 POST 是 HTTP 请求中最常用的两种请求方法，它们的底层都是基于 TCP/IP 实现的。它们的区别主要体现在 5 个方面：缓存不同、参数长度限制不同、回退和刷新不同、历史记录不同、能否保存为书签不同，但它们最大的区别是规范和约定上的不同，规范中定义 GET 是用来获取信息的，而 POST 是用来传递实体的，并且 GET 请求的参数要放在 URL 上，而 POST 请求的参数要放在请求正文中。源码附件已经打包好上传到百度云了，大家自行下载即可～... 阅读详情

客户端POST方法



private String postJsonData(String url,Object obj) {

		HttpClient client =null;

		try {

			BasicHttpParams httpParams = new BasicHttpParams();  

			ConnManagerParams.setTimeout(httpParams,10000);

			HttpConnectionParams.setConnectionTimeout(httpParams, 10000);  

			HttpConnectionParams.setSoTimeout(httpParams, 20000);  

			//DefaultHttpClient client = new DefaultHttpClient(httpParams);

			client = new DefaultHttpClient(httpParams);

			

			//HttpClient client = new DefaultHttpClient();

			//HttpParams httpParams = client.getParams();

			

			//HttpConnectionParams.setConnectionTimeout(httpParams, 10000);

			//HttpConnectionParams.setSoTimeout(httpParams, 10000);

			HttpResponse response;

			 

			 

			HttpPost httpPost = new HttpPost(url);

			httpPost.addHeader("Accept", "application/json;charset=utf-8");

			httpPost.addHeader("Content-Type", "application/json;charset=utf-8");

			Gson gson = new Gson();

			httpPost.setEntity(new StringEntity(gson.toJson(obj), "utf-8"));//

			response = client.execute(httpPost);

			 



			HttpEntity entity = response.getEntity();

			if (entity != null) {

				String result = EntityUtils.toString(entity);

				return result;

				 

			}

		} catch (ClientProtocolException e) {

			e.printStackTrace();

			// TODO Auto-generated catch block

			return null;



		} catch (IOException e) {

			// TODO Auto-generated catch block

			e.printStackTrace();

			return null;



		} catch (Exception e) {

			e.printStackTrace();

			return null;

		}finally {

			if (client != null && client.getConnectionManager() != null) {

				client.getConnectionManager().shutdown();

			}

		}

		return null;



	}

调用



String sb = postJsonData(url, ContactUsReq);

ContactUsReq是个java类已经赋值



ContactUsReq contactUsReq = new ContactUsReq();

contactUsReq.setUsername(usrInfo[0]);

contactUsReq.setRandomstring(randomstring);

contactUsReq.setVerifystring(verifystring);

contactUsReq.setContent(contact);

我想知道服务器如何获取我set的值？
