Php 谷歌云存储桶->；第403页

我试图检查Laravel PHP中是否存在一个bucket。 我在exists（）方法上得到一个403。为什么?

见第160行

您的服务帐户没有

存储.bucket.get

权限。要检查bucket是否存在并创建它，请将

角色/storage.admin

分配给您的服务帐户

有关参考，请参阅：

$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"
    } ]
} }
