如何从json中读取信息

Question

我将从客户端获取json，我需要从json获取读取信息，即MPRN = Str1234        POBoxNumber = Str1234       SubBuildingName = Str1234

使用以下代码

JSONObject inputs = new JSONObject(Json); 
jsonobject = (JSONObject)
inputs.get("Request");
String mprn = jsonobject.getString("MPRN");         
String Pno = jsonobject.getString("POBoxNumber");       
String subB = jsonobject.getString("SubBuildingName");

我收到以下错误：

com.sun.jersey.spi.container.ContainerResponse mapMappableContainerException SEVERE: The exception contained within MappableContainerException could not be mapped to a response, re-throwing to the HTTP container org.json.JSONException: JSONObject["MPRN"] not found.

Answer 1

MPRN是RequestBody的孩子，你需要先请求RequestBody才能.getString（＆＃34; MPRN＆＃34;）

Answer 2

试试此代码

    JSONObject inputs = new JSONObject("Json");

    JSONObject requestBody = inputs.getJSONObject("RequestBody");
    JSONObject address = requestBody.getJSONObject("Address");

    String mprn = requestBody.getString("MPRN");
    String Pno = address.getString("POBoxNumber");
    String subB = address.getString("SubBuildingName");

Answer 3

thnaku们......得到了解决方案

 myList = (RecyclerView) findViewById(R.id.playersVote);
    myList.setLayoutManager(new LinearLayoutManager(this));
    adapter = new CoursesAdapter(players);
    myList.setAdapter(adapter);


    // RecyclerView with a click listener

    CoursesAdapter clickAdapter = new CoursesAdapter(players);

    clickAdapter.setOnEntryClickListener(new CoursesAdapter.OnEntryClickListener() {
        @Override
        public void onEntryClick(View view, int position) {
            // Let each player vote (ghosts too)
            Player player = players.get(position);
            player.incrementCount();
            //Toast.makeText(ListPlayersVote.this, String.valueOf(player.getCount()), Toast.LENGTH_SHORT).show();
            votes++;
