Question

以下是我现有的用于将数据上传到 blobstore 的密码。

from google.appengine.api import files

def save_data_to_blob_store(data):
    # Create the file
    file_name = files.blobstore.create(mime_type='application/octet-stream')

    # Open the file and write to it
    with files.open(file_name, 'a') as f:
        f.write(data)

    # Finalize the file. Do this before attempting to read it.
    files.finalize(file_name)

    # Get the file's blob key
    blob_key = files.blobstore.get_blob_key(file_name)
    return str(blob_key)

现在我正在尝试弃用blobstore＆amp;转移到 GCS 。我写了一些代码但没有按预期工作。

def save_data_to_gcs(request):
    file_name = '/gs/bucket-name-1/new_file' # change bucket/object names to suit your needs
    writable_file_name = files.gs.create(file_name, mime_type='application/octet-stream',
                                     acl='public-read')
    with files.open(writable_file_name, 'a') as f:
        f.write('Hello World!\n')
        f.write('This is a Google Cloud Storage object!\n')
    files.finalize(writable_file_name)

执行此程序时，GAE在生产中抛出错误，

Exception in request:

    raise PermissionDeniedError(e)
 PermissionDeniedError: ApplicationError: 8

任何人都可以通过 save_data_to_gcs 程序帮助纠正我，不胜感激。

感谢。

Answer 1

GCS需要activate your project。

然后授予您的应用程序在Google Cloud Console中使用您的存储桶的权限：

为此，请选择您的存储桶，点击“存储桶权限”按钮，然后添加新的“用户”权限，提供您的应用电子邮件地址（app-id@appspot.gserviceaccount.com）并将其设为所有者。< / p>

Answer 2

由于文件api于2015年9月关闭，因此不再有效。

将Blobstore迁移到GCS：Google App Engine Python
