上传到firebase存储php

如何解决上传到firebase存储php

我正在尝试将照片上传到我的 firebase 存储桶，我的代码有点像：

$storage = new StorageClient([
        'projectId' => '<project_id>','keyFilePath' => '<path_to_json>','storageBucket' => 'images'
        ]);

      $bucket = $storage->bucket('images');

我可以让它打印存储桶的名称，但是当我上传时：

$bucket->upload(
      file_get_contents($_FILES['imagetoUpload']['tmp_name']),[
          'name' => $_FILES['imagetoUpload']['name']
      ]
  );

我收到此错误消息：

Fatal error: Uncaught Google\Cloud\Core\Exception\ServiceException: { "error": { "code": 403,"message": "[e-mail] does not have storage.objects.create access to the Google Cloud Storage object.","errors": [ { "message": "[e-mail] does not have storage.objects.create access to the Google Cloud Storage object.","domain": "global","reason": "forbidden" } ] } } in C:\xampp\htdocs\public_html\vendor\google\cloud\Core\src\RequestWrapper.PHP:368 Stack trace: #0 C:\xampp\htdocs\public_html\vendor\google\cloud\Core\src\RequestWrapper.PHP(207): Google\Cloud\Core\RequestWrapper->convertToGoogleException(Object(GuzzleHttp\Exception\ClientException)) #1 C:\xampp\htdocs\public_html\vendor\google\cloud\Core\src\Upload\MultipartUploader.PHP(44): Google\Cloud\Core\RequestWrapper->send(Object(GuzzleHttp\Psr7\Request),Array) #2 C:\xampp\htdocs\public_html\vendor\google\cloud\Storage\src\Bucket.PHP(2 in C:\xampp\htdocs\public_html\vendor\google\cloud\Core\src\RequestWrapper.PHP on line 368

有什么方法可以做到这一点而无需创建另一个服务帐户？或者我是否必须制作另一个，如果是这样，我不知道该怎么做。
