Question

我正在应用程序中使用改造2。在申请中有授权。一切正常，但还有一个问题。我有access_token和refresh_token。当我登录应用程序时，我得到了令牌。当我的access_token过期时，我可以获取带有刷新令牌的新令牌。如果刷新令牌也过期，则我再次授权获取新令牌。在我的情况下，当改装需要发送呼叫以更新令牌时，我会多次发送数据。可能是什么原因造成的？

private ApiClient(String endpoint) {
 OkHttpClient.Builder client = new OkHttpClient.Builder()
            .readTimeout(10, TimeUnit.SECONDS)
            .connectTimeout(10, TimeUnit.SECONDS)
            .writeTimeout(10, TimeUnit.SECONDS);

client.addInterceptor(new Interceptor() {
        @Override
        public Response intercept(@NonNull Chain chain) throws IOException {
            Request request = chain.request();
            request = request.newBuilder()
                    .header("Cache-Control", "public, max-age=0")
                    .build();
            return chain.proceed(request);
        }
    });

    supportopApi = new Retrofit.Builder()
            .baseUrl(endpoint)
            .client(client.build())
            .addConverterFactory(GsonConverterFactory.create())
            .build()
            .create(SupportopApi.class);
}

public static synchronized void initializeInstance(String endpoint) {
    if (instance == null) {
        instance = new ApiClient(endpoint);
    }
}


public static synchronized ApiClient getInstance() {
    if (instance == null) {
        throw new IllegalStateException("PentairAPIClient has not been initialized.");
    }
    return instance;
}

我不想在此处添加大代码，因此也可以添加更新部分。

public void updateToken() {

    //Perform this call if access token is expired

    final ApiClient apiClient = ApiClient.getInstance();
    SupportObjToken supportObjToken = new SupportObjToken();

//Here I'm setting my user information for request
    supportObjToken.setGrantType("refresh_token");
    supportObjToken.setClientId(SharedPreferencesManager.getInstance().getUserData().getClientId());
    supportObjToken.setClientSecret(SharedPreferencesManager.getInstance().getUserData().getClientSecret());
    supportObjToken.setRefreshToken(SharedPreferencesManager.getInstance().getUserData().getRefreshToken());

//This request calls multiple times (2-3 times or more)
    Call<RefreshTokenActivation> newToken = apiClient.newToken(supportObjToken);
    newToken.enqueue(new Callback<RefreshTokenActivation>() {
        @Override
        public void onResponse(Call<RefreshTokenActivation> call, Response<RefreshTokenActivation> response) {
            if (response.isSuccessful()) {
                String newAccessToken = response.body().getAccessToken();
                String newRefreshToken = response.body().getRefreshToken();

Here I'm saving my updated access_token
                UserData userData = SharedPreferencesManager.getInstance().getUserData();
                SharedPreferencesManager.getInstance().removeUser();
                userData.setAccessToken(newAccessToken);
                userData.setRefreshToken(newRefreshToken);
                SharedPreferencesManager.getInstance().setUser(userData);

                tokenUpdaterCallback.updateToken();
            } else {
                if (response.code() == 401) {

                    //Perform this call if refresh token is expired

//This request is called multiple times too
                    Call<TokenActivation> token = apiClient.getToken("password",
                            SharedPreferencesManager.getInstance().getUserData().getClientId(),
                            SharedPreferencesManager.getInstance().getUserData().getClientSecret(),
                            SharedPreferencesManager.getInstance().getUserData().getEmail(),
                            SharedPreferencesManager.getInstance().getUserData().getPassword());

                    token.enqueue(new Callback<TokenActivation>() {
                        @Override
                        public void onResponse(Call<TokenActivation> call, Response<TokenActivation> response) {
                            if (response.isSuccessful()) {
                                String access_token = response.body().getAccessToken();
                                String refresh_token = response.body().getRefreshToken();

                                UserData userData = SharedPreferencesManager.getInstance().getUserData();
                                SharedPreferencesManager.getInstance().removeUser();
                                userData.setAccessToken(access_token);
                                userData.setRefreshToken(refresh_token);
                                SharedPreferencesManager.getInstance().setUser(userData);


//tokenUpdaterCallback goes to main class and repeats the authorization request
                                tokenUpdaterCallback.updateToken();
                            }
                        }

                        @Override
                        public void onFailure(Call<TokenActivation> call, Throwable t) {
                            Toast.makeText(context, "An error occurred", Toast.LENGTH_SHORT).show();
                        }
                    });
                }
            }
        }

        @Override
        public void onFailure(Call<RefreshTokenActivation> call, Throwable t) {
            Toast.makeText(context, "Response is not successful", Toast.LENGTH_SHORT).show();
        }
    });
}

可能是什么问题？谢谢。
