无法使用 Retrofit 刷新 Bearer Token

Question

我在我的项目中使用 Retrofit 和 OkHttp，我想在服务器给出 401 错误代码时刷新令牌并将新令牌存储在共享首选项中，然后在不通知用户的情况下再次进行相同的调用。令牌类型为不记名，每小时过期。

但是我想要的输出没有出现，当令牌过期时，身份验证器什么都不做。

ApiInterface.java

public interface ApiInterface {
    @FormUrlEncoded
    @POST("auth/login")
    Call<ResponseBody> login(@FieldMap HashMap<String, Object> map);

    @FormUrlEncoded
    @POST("auth/register")
    Call<ResponseBody> register(@FieldMap HashMap<String, Object> map);

    @FormUrlEncoded
    @POST("auth/forgotpassword")
    Call<ResponseBody> forgotPassword(@FieldMap HashMap<String, Object> map);

    @POST("auth/refresh")
    Call<ResponseBody> refreshToken(@Header("Authorization") String token);

    @POST("auth/GetAllInterests")
    Call<ResponseBody> getAllInterest();

    @POST("auth/AddUserProfile")
    @Multipart
    Call<ResponseBody> addUserProfile(
            @Part("display_name") RequestBody display_name,
            @Part("children_age_show") RequestBody children_age_show,
            @Part("address") RequestBody address,
            @Part("no_of_children") RequestBody no_of_children,
            @Part("children_age") RequestBody children_age,
            @Part("date_of_birth") RequestBody date_of_birth,
            @Part("interests") RequestBody interests,
            @Part List<MultipartBody.Part> images
    );

    @POST("auth/GetUserProfile")
    Call<ResponseBody> getUserProfile();

    @FormUrlEncoded
    @POST("auth/ChangePassword")
    Call<ResponseBody> changePassword(@FieldMap HashMap<String, Object> map);

    @POST("auth/logout")
    Call<ResponseBody> logout();
}

请尝试以下方式

 (1)   HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
                interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
                OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
    
                try {
                    httpClient.addInterceptor(new Interceptor() {
                        @Override
                        public Response intercept(Interceptor.Chain chain) throws IOException {
                            Request request = chain.request();
                            // try the request
                            Response response = chain.proceed(request);
                            if (response shows expired token) {
                                // get a new token (I use a synchronous Retrofit call)
                                // create a new request and modify it accordingly using the new token
                                Request newRequest = request.newBuilder().build();
    
                                // retry the request
                                return chain.proceed(newRequest);
                            }
                            // otherwise just pass the original response on
                            return response;
                        }
                    });
                } catch (Exception e) {
                    e.printStackTrace();
                }
                String baseUrl = "";
                Retrofit retrofit = new Retrofit.Builder()
                        .client(okHttpClient)
                        .baseUrl(baseUrl)
                        .addConverterFactory(GsonConverterFactory.create())
                        .build();
                apiService = retrofit.create(ApiService.class);


(2)  public class TokenAuthenticator implements Authenticator {

        private final ApiService apiservice;

        public TokenAuthenticator(TokenServiceHolder tokenServiceHolder) {
            this.tokenServiceHolder = tokenServiceHolder;
        }

        @Override
        public Request authenticate(Proxy proxy, Response response) throws IOException {
            newtoken = apiservice.refreshToken().execute();
            return response.request().newBuilder()
                    .header(AUTHORIZATIONKEY, newtoken)
                    .build();
        }

        @Override
        public Request authenticateProxy(Proxy proxy, Response response) throws IOException {
            // Null indicates no attempt to authenticate.
            return null;
        }
    }
