推荐答案

getServingUrl() 有一个新的重载，带有一个 ServingUrlOptions 方法参数.它的构建器有一个 withGoogleStorageFileName() 方法，您可以使用该方法根据 Cloud Storage 文件名创建网址.

There is a new overload for getServingUrl() with a ServingUrlOptions method argument. And its builder has a withGoogleStorageFileName() method that you can use to create a URL based on the Cloud Storage filename.

GcsFilename gcsFilename = new GcsFilename("bucketName", "objectName");
ImagesService is = ImagesServiceFactory.getImagesService(); 
String filename = String.format("/gs/%s/%s", gcsFilename.getBucketName(), gcsFilename.getObjectName());
String servingUrl = is.getServingUrl(ServingUrlOptions.Builder.withGoogleStorageFileName(filename));

Java 文档:
