java - 在 Google Cloud Storage 中创建存储桶有时会失败

Question

我一直在尝试按照此 link 中的指南在 Google Cloud Storage 中创建存储桶。 ，使用Java。我有一个方法可以检查存储桶是否存在并返回一个 boolean 值，如下所示

private boolean checkIfBucketExists(String bucketName) {
   return storage.get(bucketName, Storage.BucketGetOption.fields()) != null
}

还有另一种实际创建存储桶的方法，如下所示

public Bucket createBucket(String bucketName) {
    if (checkIfBucketExists(bucketName)) {
      System.out.println("Bucket already exists!");
    }
    return storage.create(
        BucketInfo.newBuilder(bucketName)
            // See here for possible values: http://g.co/cloud/storage/docs/storage-classes
            .setStorageClass(StorageClass.COLDLINE)
            // Possible values: http://g.co/cloud/storage/docs/bucket-locations#location-mr
            .setLocation("eu")
            .build());
  }

当我创建存储桶时，有时它的行为有点奇怪。例如，我可以创建一个名为 name-bucket 的 bucket，但不能创建 namebucket，即使我没有现有的我的项目中的 namebucket 。它给了我这个错误

Caused by: com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden
{
  "code" : 403,
  "errors" : [ {
    "domain" : "global",
    "message" : "myservice@project-id.iam.gserviceaccount.com does not have storage.buckets.get access to namebucket.",
    "reason" : "forbidden"
  } ],
  "message" : "myservice@project-id.iam.gserviceaccount.com does not have storage.buckets.get access to namebucket."
}

在 Google Cloud Storage 中，我是否无法使用其他用户在其项目中选择的名称来创建存储桶？我无法选择名称 namebucket 的原因是因为其他人已经在他们的项目中命名了这样的存储桶吗？

Answer 1

是的，存储桶名称对于所有用户来说都是唯一的。

检查Documentation for bucket name considerations :

Bucket names reside in a single Cloud Storage namespace, which means that every bucket name must be unique. If you try to create a bucket with a name that is already assigned to an existing bucket, Cloud Storage responds with an error message. However, once you delete a bucket, its name can be reused by you or another user when creating a new bucket.
