关于Http 传输二维json

传输一维的好说

    public static String  doPost(String url) {
        String result = new String();
        OutputStream out = null;
        InputStream in = null;
        try {
            URL realUrl = new URL(url);
            HttpURLConnection urlConnection = (HttpURLConnection) realUrl.openConnection();
            urlConnection.setConnectTimeout();//设置连接超时
            urlConnection.setReadTimeout();
//            urlConnection.setRequestProperty("ser-Agent", "Fiddler");
            urlConnection.setRequestProperty("connection", "Keep-Alive");
            //urlConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
            //urlConnection.setRequestProperty("Content-Type", "text/html; charset=UTF-8");
            urlConnection.setRequestProperty("Content-Type",  "application/json");
            urlConnection.setRequestMethod("POST");
            // 发送POST请求必须设置如下两行
            urlConnection.setDoOutput(true);
            urlConnection.setDoInput(true);
            urlConnection.setChunkedStreamingMode();
            // 获取URLConnection对象对应的输出流
            out = new BufferedOutputStream(urlConnection.getOutputStream());
            // 发送请求参数
//            String postContent =
//                    URLEncoder.encode("userName", "UTF-8") + "=" +
//                    URLEncoder.encode("admin", "UTF-8") + "&" +
//                    URLEncoder.encode("passWord", "UTF-8") + "="+
//                    URLEncoder.encode("admin", "UTF-8") ;

            JSONObject jsonObject = new JSONObject();
            jsonObject.put("cmd","mobile");
            jsonObject.put("param","00000000000");
            Data  = jsonObject.toString();

            //String json = java.net.URLEncoder.encode(jsonObject.toString(), "utf-8");

            Log.e("数据", Data );

//            String  postContent ="cmd="
//                    +URLEncoder.encode("check_mobile", "utf-8") + "&" +
//                    "mobile="+
//                    URLEncoder.encode("18363890557", "utf-8");

            //Log.e("err",postContent);

            out.write(Data.getBytes());
            out.flush();
            out.close();
            if (urlConnection.getResponseCode() == ) {
                InputStreamReader inputStreamReader = new InputStreamReader(urlConnection.getInputStream(),"UTF-8");
                BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
                String ee=null;
                while ((ee = bufferedReader.readLine())!=null)
                {
                    result = ee;
                    Log.e("err","接收到数据="+result);
                }
            }else {
                result = null;
            }
        } catch (Exception e) {
            Log.e("err",e+"");
        } finally {//使用finally块来关闭输出流、输入流
            try {
                if (out != null) {
                    out.close();
                }
                if (in != null) {
                    in.close();
                }
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        }
        return result;
    }

然后直接用任务

new Thread(new Runnable() {
            @Override
            public void run () {

                String sss = doPost("http://具体的地址");
                //Log.e("err","Read="+sss);
            }
        }).start();

现在说二维的

假设要封装成这样

{ "cmd":"check_mobile", "param":{ "mobile":"" } }

后面的是一个二维的json

一开始我以为

JSONObject jsonObject1 = new JSONObject();
            jsonObject1.put("mobile","");
            String str = jsonObject1.toString();

            JSONObject jsonObject = new JSONObject();
            jsonObject.put("cmd","check_mobile");
            jsonObject.put("param",str);
            Data  = jsonObject.toString();

不可以....发现数据是这样的

然后就在想是不是   String str = jsonObject1.toString();    jsonObject.put("param",str);   不应该这样

所以

            JSONObject jsonObject1 = new JSONObject();
            jsonObject1.put("mobile","");
            //String str = jsonObject1.toString();

            JSONObject jsonObject = new JSONObject();
            jsonObject.put("cmd","check_mobile");
            jsonObject.put("param",jsonObject1);
            Data  = jsonObject.toString();

这样就可以了

后来尝试了其它各种方式

发现用Map也是可以的

Map map1 = new HashMap<String,String>();
            map1.put("mobile","");

            Map map2 = new HashMap<String,Object>();
            map2.put("cmd","check_mobile");
            map2.put("param",map1);

            String Data = new JSONObject(map2).toString();
