Servlet处理Json请求数据包

request.setCharacterEncoding(“UTF-8”);

response.setContentType(“text/html;charset=UTF-8”);

String acceptjson = “”;

try {

BufferedReader br = new BufferedReader(new InputStreamReader(

(ServletInputStream) request.getInputStream(), “utf-8”));

StringBuffer sb = new StringBuffer(“”);

String temp;

while ((temp = br.readLine()) != null) {

sb.append(temp);

}

br.close();

acceptjson = sb.toString();

if (acceptjson != “”) {

JSONObject jo = JSONObject.fromObject(acceptjson);

JSONArray imgArray = jo.getJSONArray(“PartsImages”);

JSONArray infArray = jo.getJSONArray(“BasicInfo”);

for (int i = 0; i < imgArray.size(); i++) {

JSONObject imgObject = JSONObject.fromObject(imgArray

.get(i));

System.out.println(imgObject.get(“PartsImg”));

}

JSONObject infObject = JSONObject.fromObject(infArray.get(0));

System.out.println(infObject.get(“Parts_cate”));

System.out.println(infObject.get(“Supplement”));

System.out.println(jo.toString());

}

response.getWriter().write(MyReadFile.read(“/post/publishsuccess”));

} catch (Exception e) {

客户端发请求

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.util.List;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.client.ClientProtocolException;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.entity.StringEntity;

import org.apache.http.impl.client.DefaultHttpClient;

import org.json.JSONArray;

import org.json.JSONException;

import org.json.JSONObject;

import android.telephony.TelephonyManager;

public class Location {

public static String LOCATIONS_URL = “http://www.google.com/loc/json”;

public static String getLocations(Context context) {

// generate json request

String jr = generateJsonRequest(context);

try {

DefaultHttpClient client = new DefaultHttpClient();

StringEntity entity = new StringEntity(jr);

HttpPost httpost = new HttpPost(LOCATIONS_URL);

httpost.setEntity(entity);

HttpResponse response = client.execute(httpost);

String locationsJSONString = getStringFromHttp(response.getEntity());

return extractLocationsFromJsonString(locationsJSONString);

} catch (ClientProtocolException e) {

//e.printStackTrace();

} catch (IOException e) {

} catch (Exception e) {

//e.printStackTrace();

}

return null;

}或者：

HttpClient httpClient = new DefaultHttpClient();         HttpPost postMethod = new HttpPost(url);                  final StringEntity entity = new StringEntity(json, “UTF-8”);         entity.setContentEncoding(new BasicHeader(HTTP.CONTENT_ENCODING, Consts.UTF_8.toString()));         entity.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, “application/json;charset=UTF-8”));                  postMethod.setEntity(entity);                //         startTime = System.currentTimeMillis();         final HttpResponse response = httpClient.execute(postMethod);                  // 读取请求结果         if (HttpStatus.SC_OK == response.getStatusLine().getStatusCode()) {             final HttpEntity httpEntity = response.getEntity();             jsonResponse = EntityUtils.toString(httpEntity);                      }         endTime = System.currentTimeMillis();         System.out.println(“返回:” + jsonResponse);
