【问题描述】:
这是我现有的用于将数据上传到 blobstore 的 py 代码。
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 并迁移到 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)
在执行此过程时,GAE 在生产中抛出错误,
Exception in request:

任何人都可以在 save_data_to_gcs 程序中帮助纠正我,不胜感激。
谢谢。
【问题讨论】:
-
您是否激活了 GCS(启用计费等)?在 Google Cloud Console 中,您是否授予您的应用访问您的存储桶的权限?为此,请选择您的存储桶,单击“存储桶权限”,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) 并使其成为所有者。

@MarkSimpson:谢谢哥们。它就像魅力一样。我还需要一个帮助,如何获得文件记录的唯一密钥?

好的,我已经把我的评论变成了下面的答案。请接受它是正确的。单独发布该新问题。它与这个问题无关。谢谢。
