url带参数的写法：

url+/?r=m/calendar/contact_list&uid=3&&subscriptionslist[pageindex]=10&subscriptionslist[recordlimit]=10

 

从“&”符号之后一连串都是参数。

发送方式代码编写：

DefaultHttpClient httpClient = new DefaultHttpClient();

        HttpPost httpPost = new HttpPost(HttpUtil.BASIC_URL

                + HttpUtil.SUBSCRIPTION_URL);

        try{

            if (cookie != null) {

               // httpClient.setCookieStore(LoginJsonUtil.cookie);

                List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2);

                nameValuePair.add(new BasicNameValuePair("uid",

                        uid));

                nameValuePair.add(new BasicNameValuePair("subscriptionslist[pageindex]",

                        subscriptionslist_pageindex));

                nameValuePair.add(new BasicNameValuePair("subscriptionslist[recordlimit]",

                        subscriptionslist_recordlimit));

                httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));

传递参数使用nameValuePair。

如果使用cookie的话，使用上段代码中注释掉的部分

httpClient.setCookieStore(LoginJsonUtil.cookie);

 

使用json数据格式发送信息向服务器端：

HttpClient httpClient = new DefaultHttpClient();

        try {

            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()));

            Log.i("lifeweeker", jsonObject2.toString());

            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));

这里每个put的顺序我不清楚有没有规定，我是严格按照提供的前后顺序来组合json数据格式的。

前面我有用到；这里我想总结一下我用到的解析json数据格式的方式

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：

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

分析代码如下：

// TODO 状态处理 500 200

                int res = 0;

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

                if (res == 200) {

                   

                    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：

{"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：

// TODO 状态处理 500 200

                int res = 0;                res = httpClient.execute(httpPost).getStatusLine().getStatusCode();                if (res == 200) {                                        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("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。
