Android接收/发送jSON数据

原文地址：/article/7769764.html

一、接收

例1：

服务器返回的json数据格式如下：

{"userbean":{"Uid":"100196","Showname":"\u75af\u72c2\u7684\u7334\u5b50","Avtar":null,"State":1}}

解析代码：

//TODO 状态处理 500 200

int res = 0;

res = httpClient.execute(httpPost).getStatusLine().getStatusCode();

if (res == 200) {

/*

* 当返回码为200时，做处理

* 得到服务器端返回json数据，并做处理

* */

HttpResponse httpResponse = httpClient.execute(httpPost);

StringBuilder builder = new StringBuilder();

BufferedReader bufferedReader2 = new BufferedReader(

new InputStreamReader(httpResponse.getEntity().getContent()));

String str2 = "";

for (String s = bufferedReader2.readLine(); s != null; s = bufferedReader2.readLine()) {

builder.append(s);

}

JSONObject jsonObject = new JSONObject(builder.toString())

.getJSONObject("userbean");

String Uid;

String Showname;

String Avtar;

String State;

Uid = jsonObject.getString("Uid");

Showname = jsonObject.getString("Showname");

Avtar = jsonObject.getString("Avtar");

State = jsonObject.getString("State");

}

例2：

服务器返回的json数据格式如下：

{"calendar":

{"calendarlist":

[

{"calendar_id":"1705","title":"(\u4eb2\u5b50)ddssd","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288927800","endshowtime":"1288931400","allDay":false},

{"calendar_id":"1706","title":"(\u65c5\u884c)","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288933200","endshowtime":"1288936800","allDay":false}

]

}

}

解析代码：

// TODO 状态处理 500 200

int res = 0;

res = httpClient.execute(httpPost).getStatusLine().getStatusCode();

if (res == 200) {

/*

* 当返回码为200时，做处理

* 得到服务器端返回json数据，并做处理

*/

HttpResponse httpResponse = httpClient.execute(httpPost);

StringBuilder builder = new StringBuilder();

BufferedReader bufferedReader2 = new BufferedReader(

new InputStreamReader(httpResponse.getEntity().getContent()));

String str2 = "";

for (String s = bufferedReader2.readLine(); s != null; s = bufferedReader2

.readLine()) {

builder.append(s);

}

/*

* 这里需要分析服务器回传的json格式数据，

*/

JSONObject jsonObject = new JSONObject(builder.toString())

.getJSONObject("calendar");

JSONArray jsonArray = jsonObject.getJSONArray("calendarlist");

for(int i=0;i<jsonArray.length();i++){

JSONObject jsonObject2 = (JSONObject)jsonArray.opt(i);

CalendarInfo calendarInfo = new CalendarInfo();

calendarInfo.setCalendar_id(jsonObject2.getString("calendar_id"));

calendarInfo.setTitle(jsonObject2.getString("title"));

calendarInfo.setCategory_name(jsonObject2.getString("category_name"));

calendarInfo.setShowtime(jsonObject2.getString("showtime"));

calendarInfo.setEndtime(jsonObject2.getString("endshowtime"));

calendarInfo.setAllDay(jsonObject2.getBoolean("allDay"));

calendarInfos.add(calendarInfo);

}

}

二、发送

HttpClient httpClient = new DefaultHttpClient();

HttpPost httpPost = new HttpPost(BASIC_URL + url);

List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>();

JSONObject jsonObject = new JSONObject();

JSONObject jsonObject2 = new JSONObject();

jsonObject.put("uemail", userbean.getEmail());

jsonObject.put("password", userbean.getPassword());

jsonObject2.put("userbean", jsonObject);

nameValuePair.add(new BasicNameValuePair("jsonString", jsonObject

.toString()));

httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
