json - JSON

JSON(JavaScript Object Notation)是一种轻量级的数据交换格式, 是目前最见的数据交换方式， 具体请参考 https://baike.baidu.com/item/JSON 或 https://en.wikipedia.org/wiki/JSON .

TiJOS Framework中的JSON实现来自https://github.com/stleary/JSON-java, 支持JSONArray, JSONObject, JSONString, 具体可参考相关资料.

Java包

tijos.framework.util

主要类说明

类	说明
JSONObject	JSON对象, 可用于构造JSON字符串
JSONArray	JSON数组
JSONTokener	JSON解析类

具体使用方法可参考 https://blog.csdn.net/jediael_lu/article/details/25779087

注意，钛极OS的JSON不支持与反射有关的方法

例程:

1. JSON格式编码

//Generate JSON string
JSONObject studentJSONObject = new JSONObject();  
try {  
         studentJSONObject.put("name", "Jason");  
         studentJSONObject.put("id", 20130001);  
         studentJSONObject.put("phone", "13579246810");  
     } catch (JSONException e) {  
            e.printStackTrace();  
     }  

1. JSON格式解码

final String JSON =   
              "{" +  
                  "   \"phone\" : [\"12345678\", \"87654321\"]," +  
                  "   \"name\" : \"jack\"," +  
                  "   \"age\" : 21," +  
                  "   \"address\" : { \"country\" : \"china\", \"province\" : \"beijing\" }," +  
                  "   \"married\" : false," +  
              "}";  

              try {  
                  JSONTokener jsonTokener = new JSONTokener(JSON);  
                  JSONObject person = (JSONObject) jsonTokener.nextValue();  

                  JSONArray phoneArray = person.getJSONArray("phone");
                  for(int i = 0; i < phoneArray.length(); i ++)
                  {
                      System.out.println("Phone" + i);
                      System.out.println(phoneArray.getString(i));
                  }

                  System.out.println(person.getString("name"));  
                  System.out.println(person.getInt("age"));  

                  JSONObject addr = person.getJSONObject("address");
                  System.out.println(addr.getString("country"));
                  System.out.println(addr.getString("province"));

                  System.out.println(person.getBoolean("married"));  
              } catch (JSONException ex) {  
                   ex.printStackTrace();
              }
