Android: Retrofit beta2.0 ServiceClass with interface.无法理解为什么在不使用时使用接口

Question

我不知道我的界面不工作。当我在界面中更改 URL 时，程序可以正常工作。但是，当我将 URL 从 REQUEST 更改为 URL 时，就会发生错误。什么原因。请帮我解决这个问题。

提前致谢

public class Service{
private static GitApiInterface gitApiInterface;
private static final String baseUrl = "https://api.vimeo.com/channels/";

public static GitApiInterface getClient() {
    if (gitApiInterface == null) {
        OkHttpClient okClient = new OkHttpClient();
        okClient.interceptors().add(new Interceptor() {
            @Override
            public Response intercept(Chain chain) throws IOException {

                Request request = new Request.Builder()
                        .url(baseUrl + "staffpicks/videos")
                        .get()
                        .addHeader("Accept", "application/json")
                        .addHeader("Authorization", "Bearer " + accessToken)
                        .addHeader("cache-control", "no-cache")
                        .build();
                Log.e("Request ", "" + request.url());

                Response response = chain.proceed(request);                    
                return response;
            }
        });

        Retrofit client = new Retrofit.Builder()
                .baseUrl(baseUrl)
                .client(okClient)
                .addConverterFactory(new ToStringConverter())
                .build();
        gitApiInterface = client.create(GitApiInterface.class);
    }
    return gitApiInterface;
}


public interface GitApiInterface {

    @GET("staffpicks/videos")
    Call<String> getVimeoVideoData();

   }
}

您的请求是 url 正在“https://api.vimeo.com/channels/staffpicks/videosstaffpicks/videos”。因为您要添加 "staffpicks/videos" 两次。

Retrofit 自动添加给定的注解，表示接口中的方法到基 url 的末尾。

Request request = new Request.Builder()
                    .url(baseUrl + "staffpicks/videos")
                    .get()
                    .addHeader("Accept", "application/json")
                    .addHeader("Authorization", "Bearer " + accessToken)
                    .addHeader("cache-control", "no-cache")
                    .build();

在本节中，“.url()”应该用于基础 urls。
