为什么返回的数据类型不是json 

Answer 1

json数据格式解析我自己分为两种；一种是普通的，一种是带有数组形式的；普通形式的：服务器端返回的json数据格式如下：复制代码代码如下:{"userbean":{"Uid":"100196","Showname":"\u75af\u72c2\u7684\u7334\u5b50","Avtar":null,"State":1}}分析代码如下：复制代码代码如下:// TODO 状态处理 500 200int 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);}Log.i("cat", ">>>>>>" + builder.toString());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");带数组形式的：服务器端返回的数据格式为：复制代码代码如下:{"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}]}}分析代码如下：复制代码代码如下:// TODO 状态处理 500 200int 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);}Log.i("cat", ">>>>>>" + builder.toString());/*** 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);}总结，普通形式的只需用JSONObject ，带数组形式的需要使用JSONArray 将其变成一个list。
