Android 改型返回LinkedTreeMap而不是JSON

我使用改型2.0从返回json文本的web服务读取数据，但在以下代码中，响应是LinkedTreeMap，我无法将其转换为json：

我的界面

public interface GeoAPIInterface {
    String ENDPOINT = "http://www.geoplugin.net/";

    @GET("json.gp")
    Call<Object> getIP(@Query("ip") String ip);
}

我建议您使用创建对象

而不是

Call<Object> getIP(@Query("ip") String ip);

调用getIP（@Query（“ip”）字符串ip）；

你会有

Call<myObject> getIP(@Query("ip") String ip);

调用getIP（@Query（“ip”）字符串ip）；

---

其中，

myObject

将是您的自定义对象，所有字段都在

@JSONProperty

中用适当的名称注释。这是一款非常酷且易于使用的东西。

将您的

响应

替换为

响应

这个对象中已经有了所有参数，不需要转换和解析JSON。 您可以从JSON获取对象。

您希望接收的“JSON”格式是什么？您要获取什么类型的对象？请检查

Call<myObject> getIP(@Query("ip") String ip);
