JSONObject简单测试使用

String str = "{‘status‘:1,‘message‘:‘制作证书成功‘,‘data‘:{‘userId‘:‘‘,‘buf‘:‘‘,‘bufP7‘:‘‘,‘certDn‘:‘‘,‘certSn‘:‘‘,‘issuerDn‘:‘‘,‘startTime‘:‘‘,‘endTime‘:‘‘}";

JSONObject j = new JSONObject();

HashMap<String, String> map = new HashMap<String, String>();

map.put("map1", "map1");

map.put("map2", "map2");

map.put("map3", "map3");

j.put("files", map);

j.put("test", "test");

j.put("test1", "test1");

System.out.println(j.toString());

String str1 = j.toString();

JSONObject json = JSONObject.fromObject(str1);

System.out.println(json.get("files"));

JSONObject j2 = JSONObject.fromObject(json.get("files"));

System.out.println(j2.get("map1"));

输出结果：

{"files":{"map3":"map3","map2":"map2","map1":"map1"},"test":"test","test1":"test1"}

{"map3":"map3","map2":"map2","map1":"map1"}

map1
