php - Google Cloud Storage 存储桶->存在给出 403

Question

我正在尝试检查 Laravel PHP 中是否存在存储桶。我在 contains() 方法上收到 403 错误。为什么？

参见第 160 行 https://github.com/googleapis/google-cloud-php/blob/master/Storage/src/Bucket.php

$storageClient = new \Google\Cloud\Storage\StorageClient([
    'projectId' => env('GCS_PROJECT_ID'),
    'keyFilePath' => storage_path(env('GCS_KEY_FILE')),
]);
$bucket = $storageClient->bucket('mybucketname');

if (!$bucket->exists()) {
    $bucket = $storageClient->createBucket('mybucketname');
}

{ "error": {
    "code": 403,
    "message": "myaccount@api-project-xxxxxxxxx.iam.gserviceaccount.com does not have storage.buckets.get access to downloads.",
    "errors": [ {
        "message": "myaccount@api-project-xxxxxxxx.iam.gserviceaccount.com does not have storage.buckets.get access to mybucketname.",
        "domain": "global",
        "reason": "forbidden"
    } ]
} }

您的服务帐户没有 storage.buckets.get 权限。要检查存储桶是否存在并创建它，请将 roles/storage.admin 分配给您的服务帐户。
