应用程序默认凭据不适用于 mac Google Cloud Storage 中的环境变量设置

 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

不断收到上述错误，而是我使用以下命令在本地计算机上设置了环境变量

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

如果我在终端上使用以下命令检查环境变量的路径，它会显示变量的路径

echo $GOOGLE_APPLICATION_CREDENTIALS

在 Micronaut 应用程序上，我尝试在启动期间创建一个存储桶

@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();
        }
    }
}

关于服务

@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();
    }
}

运行应用程序时环境变量为NULL

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

The GoogleCredentials credentials = GoogleCredentials.getApplicationDefault();导致异常为

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.

是否开启StartupEventmicronaut无法访问环境变量？

好吧，我错过了以下说明

本地开发/测试

如果在本地运行进行开发/测试，您可以使用Google Cloud SDK。创建应用程序默认凭据gcloud auth application-default login，然后 google-cloud 将自动检测此类凭据。

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

然而，这个解决方案并不完美，因为它使用 OAuth 身份验证并收到警告：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.
