Question

我正在使用 retrofit2 进行网络调用，并使用 GSON 作为解析 JSON 的转换器。我想解析一个键不固定的json结构。 需要帮助创建相同的模型/bean。 这是我要解析的 JSON。user_card 数组中的键不断变化。

只需在 CardArray 对象中使用 Map 字段

import java.util.Map;

class Parent {
    public boolean isNewVersionAvailable;
    public boolean ishotelslive;
    public boolean error;
    public String message;
    public CardArray cardArray;
}

class CardArray {
    public int status;
    public String msg;
    public Map<String, Card> user_cards;
}

class Card {
    public String name_on_card;
    public String card_name;
    public String expiry_year;
    public String expiry_month;
    public String card_type;
    public String card_token;
    public int is_expired;
    public String card_mode;
    public String card_cvv;
    public String card_no;
    public String card_brand;
    public String card_bin;
    public String isDomestic;
}
