安卓云语音API返回代码=未经验证,原因=java。木卫一。IOException:获取服务帐户的访问令牌时出错:

我在我的应用程序中使用谷歌云语音API(通过gRPC的StreamingRecognite)进行语音识别。我在Android设备API级别上遇到了身份验证问题<;二十三,

Status{code=UNAUTHENTICATED, description=null, cause=java.io.IOException: Error getting access token for service account: }

我并不是每次都会遇到这个错误,只是在特定的情况下。我有两项活动。让我们命名A和B

活动A有一个按钮,用于启动活动B。 活动B与Google云语音API通信,并在TextView中显示结果

我在执行以下步骤后(在三星GT-P5110(Android 4.2.2)上)出现此错误:

  1. 启动活动A->;按下按钮开始活动B

//第一次一切都很好。我从服务器接收结果并显示它

  1. 关闭活动B(按后退按钮或呼叫后退按钮或完成)

  2. 按下按钮开始活动B。

//在这一刻,我得到了上面显示的错误

我在联想A1000(API 5.0.1)和小米Mi4c(5.0.1)上出现此错误,原因是:

  1. 启动活动A->;按下按钮开始活动B。

  2. 关闭活动B(按后退按钮或呼叫后退按钮或完成)

  3. 按下按钮开始活动B。

//一切都好

  1. 关闭活动B(按后退按钮或呼叫后退按钮或完成)

  2. 最小化应用程序

  3. 5-6分钟或更长时间后,返回活动A。

  4. 开始活动B.

//在这一刻,我总是遇到这个错误

重新启动应用程序后,一切正常,但重新打开活动B后出现错误

谁知道我怎样才能解决这个问题

我使用Play Services动态安全提供程序(It is required for gRPC)。 我安装了最新版本的Google Play Services(9.6.83)。这并不能解决问题

我通过以下代码创建ManagedChannel:

GoogleCredentials creds = GoogleCredentials.fromStream(credentials);
    creds = creds.createScoped(OAUTH2_SCOPES);
    OkHttpChannelProvider provider = new OkHttpChannelProvider();
    OkHttpChannelBuilder builder = provider.builderForAddress(host, port);
ManagedChannel channel = builder.intercept(new ClientAuthInterceptor(creds, Executors
            .newSingleThreadExecutor
                    ()))
            .build();

private static final List<String> OAUTH2_SCOPES =
        Arrays.asList("https://www.googleapis.com/auth/cloud-platform");

创建SpeechGrpc。演讲稿:

SpeechGrpc.SpeechStub mSpeechClient = SpeechGrpc.newStub(channel);

    我报告了这个问题

    出现此问题的原因是您正在应用程序中嵌入服务帐户凭据。一段时间后,当创建的令牌在内部刷新时,将从以下位置引发错误:

    com.google.auth.oauth2.ServiceAccountCredentials.refreshAccessTokenlink

    在生产环境中,您将从服务器提供访问令牌,因此能够实例化GoogleCredentials,如下所示:

        final GoogleCredentials googleCredentials = new GoogleCredentials(accessToken) {
            @Override
            public AccessToken refreshAccessToken() throws IOException {
                return accessToken;
            }
        }.createScoped(OAUTH2_SCOPES);
    

    这将防止抛出错误
