Java 在返回动态顶级JSON的api中使用改型和Gson
Im使用改装访问以下api：Java 在返回动态顶级JSON的api中使用改型和Gson,java,android,json,gson,retrofit2,Java,Android,Json,Gson,Retrofit2,Im使用改装访问以下api： near_earth_objects对象包含多个数组，每个数组都有一个表示日期的键。如果访问不同的日期，此值会明显更改 像往常一样，我根据返回的JSON结构定义了POJO。以下是我的主要回答类： public class AsteroidResponse { private Links links; @SerializedName("element_count") private Integer elementCount; @
near_earth_objectspublic class AsteroidResponse {
private Links links;
@SerializedName("element_count")
private Integer elementCount;
@SerializedName("near_earth_objects")
private NearEarthObjects nearEarthObjects;
private Map<String, Object> additionalProperties = new HashMap<String, Object>();
//getters and setters
}
Mappublic class NearEarthObjects {
private Map<String, Observation> observation = new HashMap<>();
private Map<String, Object> additionalProperties = new HashMap<String, Object>();
}
公共类近地天体{
私有映射观察=新HashMap（）；
私有映射additionalProperties=new HashMap（）；
}
不幸的是，这一次，这种方法似乎并不像预期的那样有效。地图将被返回为空。可能是什么问题？构造模型以正确解析返回的JSON的最佳方法是什么？我认为解析对象
近地天体内的JSON
数据的简单方法是这样构造返回的JSON：
