Java 如何处理翻新RestAdapter.Builder（）异常？

我使用改型连接到用户可配置的URL，我遇到的问题是如何处理空白URL。正如预期的那样，当服务器为null/blank时，RestAdapter.Builder会抛出一个IllegalArgumentException，这意味着无法调用create来生成改型接口，给我留下一个null接口

例如，使用以下API接口

interface IApiService {
        @POST("/{path}/api/{userid}/calls/Action")
        void startCall(@Path("path") String path, @Path("userid") String userid, @Body Action action, Callback<Response> callback);

        @PUT("/{path}/api/{userid}/calls/Action")
        void addToCall(@Path("path") String path, @Path("userid") String userid, @Body Action action, Callback<Response> callback);
} 

但这是不可能的，因为IApiService接口使用的是Regulation回调接口，该接口需要一个故障参数RegulationError

我列出的任何选项都可以吗？还是有更好的解决方案来处理无法生成接口的情况

我正在使用改型连接到用户可配置的URL

您应该立即验证并拒绝来自其来源的空白URL。你的应用程序永远不应该使用无效的URL构建

RestAdapter

立即拒绝的一个重要原因是避免掩盖问题。如果有不好的数据，它需要在被发现后立即浮出水面，而不是隐藏在拒绝API调用的接口的伪实现后面

public class ApiServiceWrapper implements IAPiServiceWrapper {

        private IApiService mAPiService;

                    .setRequestInterceptor(requestInterceptor)
                    .setConverter(new ActionConverter())
                    .build();

        }
