android应用怎么样在服务器端解析从客户端发送过来的json数据

如题所述

android中使用HTTP将数据发送到服务器。HTTP可使用android自带的httpclient框架实现。服务器得到请求参数再做解析即可。以下是示例代码：
1. GET 方式传递参数
//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", "数据")); //增加参数1
params.add(new BasicNameValuePair("param2", "value2"));//增加参数2
String param = URLEncodedUtils.format(params, "UTF-8");//对参数编码

String baseUrl = "服务器接口完整URL";

HttpGet getMethod = new HttpGet(baseUrl + "?" + param);//将URL与参数拼接
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) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

2. POST方式 方式传递参数
//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"));//增加参数1
params.add(new BasicNameValuePair("param2", "第二个参数"));//增加参数2
try {
HttpPost postMethod = new HttpPost(baseUrl);//创建一个post请求
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) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
