为什么会出现这个错误？

public interface API {
@GET("getmenu.php")
Observable<List <MainMenu>> getMenu();
}

MainMenu.class :

public class MainMenu {
    public String ID;
    public String Name;
    public String Link;

}

Answer 1

您收到错误是因为 json 中的内容不符合 List <MainMenu> 模型。如果您想获得具体答案，post 您的 json 和 MainMenu 模型。
