当“参数”名称改变时，用Gson读取Json返回

Question

我正在开发一个应用程序客户端来与 Open Library API ( https://openlibrary.org/developers/api ) 连接，以通过 Gson 从 google 获取 Json 返回读取的一些信息，但我有一个参数/的问题更改名称的属性。我发送了此请求https://openlibrary.org/api/books?bibkeys=ISBN:9788580415544&jscmd=details&format=json 按 ISBN (9788580415544) 搜索，并且 json 返回具有包含此编号的属性 (ISBN:9788580415544)，我可以'不要把信息带进去。如果我使用另一个 ISBN 更改请求，我将得到一个带有另一个参数/属性名称的 json

请问我该怎么办？

Answer 1

我建议将顶级对象读取为Map<String, ObjetoDetalhe>{&nbsp; &nbsp;&nbsp;"ISBN:9788580415544":&nbsp;{...} }"ISBN:9788580415544"will 是关键，the&nbsp;{...}will 是ObjetoDetalhe对象。

Answer 2

public&nbsp;class&nbsp;Objeto&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;private&nbsp;map<String,&nbsp;ObjetoDetalhe>&nbsp;obejtodetalhe; &nbsp;&nbsp;&nbsp;&nbsp;....请更换型号
