Android 如何用HttpClient 以Post方式提交数据并添加http头信息(2)

 JSONObject obj = new JSONObject();
 obj.put("name", "your name");
 obj.put("parentId", "your parentid");
 httppost.setEntity(new StringEntity(obj.toString())); 
 HttpResponse response;
 response = httpclient.execute(httppost);
 //检验状态码，如果成功接收数据
 int code = response.getStatusLine().getStatusCode();
 if (code == 200) {
  String rev = EntityUtils.toString(response.getEntity());//返回json格式： {"id": "27JpL~j4vsL0LX00E00005","version": "abc"}  
  obj = new JSONObject(rev);
  String id = obj.getString("id");
  String version = obj.getString("version");
 }
 } catch (ClientProtocolException e) { 
 } catch (IOException e) { 
 } catch (Exception e) { 
 }
}主要用到的类有：org.apache.http.client.HttpClient 、org.apache.http.client.methods.HttpPost 和 org.json.JSONObject
