java - 如何在 Java 中将一个 JSON 字符串拆分为两个 JSON 对象

Question

我有一个 JSON 对象，如下所示:

{  
   "token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9",
   "user":{  
      "pk":17,
      "username":"user1",
      "email":"user1@gmail.com",
      "first_name":"",
      "last_name":""
   }
}

我试图从中获取两个 JSON 对象； token 和用户。我尝试了两种不同的方法，但都失败了:

//response.body().string() is the above json object
JSONArray jsonArray = new JSONArray(response.body().string());

jsonObjectRoot = new JSONObject(response.body().string());

谁能告诉我如何将其拆分为两个 JSON 对象？

你可以这样拆分:

// source object
JSONObject sourceObject = new JSONObject(sourceJson);

String tokenKey = "token";
// create new object for token
JSONObject tokenObject = new JSONObject();

// transplant token to new object
tokenObject.append(tokenKey, sourceObject.remove(tokenKey));
// if append method does not exist use put
// tokenObject.put(tokenKey, sourceObject.remove(tokenKey));

System.out.println("Token object => " + tokenObject);
System.out.println("User object => " + sourceObject);

以上代码打印:

Token object => {"token":["eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9"]}
User object => {"user":{"last_name":"","pk":17,"first_name":"","email":"user1@gmail.com","username":"user1"}}
