應用程序默認憑據不適用於 mac Google Cloud Storage 中的環境變量設置

Question

 The Application Default Credentials are not available.
 They are available if running in Google Compute Engine.
 Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials

不斷收到上述錯誤，而不是我使用以下命令在本地機器上設置了環境變量

export GOOGLE_APPLICATION_CREDENTIALS="/Users/macbook/Downloads/fetebird-2b6fa8261292.json"

如果我在終端上使用以下命令檢查環境變量的路徑，它會顯示變量的路徑

echo $GOOGLE_APPLICATION_CREDENTIALS

在 Micronaut 應用程序上，我試圖在啟動期間創建一個存儲桶

@Singleton
public class StartUp implements ApplicationEventListener<StartupEvent> {
    private final GoogleCloudStorageService googleCloudStorageService;

    public StartUp(GoogleCloudStorageService googleCloudStorageService) {
        this.googleCloudStorageService = googleCloudStorageService;
    }

    @Override
    public void onApplicationEvent(StartupEvent event) {
        try {
            this.googleCloudStorageService.createBucketWithStorageClassAndLocation().subscribe();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

在服務上

@Singleton
public record GoogleCloudStorageService(GoogleCloudStorageConfiguration googleUploadObjectConfiguration, GoogleCredentialsConfiguration googleCredentialsConfiguration) {

    private static final Logger LOG = LoggerFactory.getLogger(GoogleCloudStorageService.class);

    public Observable<Void> createBucketWithStorageClassAndLocation() throws IOException {
        GoogleCredentials credentials = GoogleCredentials.getApplicationDefault(); // fromStream(new FileInputStream(googleCredentialsConfiguration.getLocation()));
        Storage storage = StorageOptions.newBuilder().setCredentials(credentials).setProjectId(googleUploadObjectConfiguration.projectId()).build().getService();
        StorageClass storageClass = StorageClass.COLDLINE;
        try {
            Bucket bucket =
                    storage.create(
                            BucketInfo.newBuilder(googleUploadObjectConfiguration.bucketName())
                                    .setStorageClass(storageClass)
                                    .setLocation(googleUploadObjectConfiguration.locationName())
                                    .build());
            LOG.info(String.format("Created bucket %s in %s with storage class %s", bucket.getName(), bucket.getLocation(), bucket.getStorageClass()));
        } catch (Exception ex) {
            LOG.error(ex.getMessage());
        }
        return Observable.empty();
    }
}

運行應用程序時環境變量為 NULL

System.out.println(System.getenv("GOOGLE_APPLICATION_CREDENTIALS"))

GoogleCredentials credentials = GoogleCredentials.getApplicationDefault(); 導致異常為

java.io.IOException: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials.

是在StartupEvent上 micronaut 沒有訪問環境變量嗎？

好吧，我錯過了以下說明

本地開發/測試

如果在本地運行以進行開發/測試，您可以使用Google Cloud SDK 。 使用gcloud auth application-default login創建應用程序默認憑據，然后 google-cloud 將自動檢測此類憑據。

https://github.com/googleapis/google-cloud-java

但是，此解決方案並不完美，因為它使用 OAuth 身份驗證並收到警告，因為Your application has authenticated using end user credentials from Google Cloud SDK. We recommend that most server applications use service accounts instead. If your application continues to use end user credentials from Cloud SDK, you might receive a "quota exceeded" or "API not enabled" error. For more information about service accounts.
