AuthorizationError：期望来自 Google Storage 的状态 [201]。但得到状态 401

Question

我正在尝试通过“App Engine”在谷歌云存储中创建一个新文件。我已授予存储桶服务帐户的完全权限，但仍然收到以下错误。

代码：

import cloudstorage as _gcs

from google.appengine.api import app_identity,urlfetch

class get_ad_insights(webapp.RequestHandler):
    def get(self):
        bucket_name = 'awstogcs'
        bucket = '/' + bucket_name
        filename = bucket + '/facebook_data'
        self.tmp_filenames_to_clean_up = []

        write_retry_params = _gcs.RetryParams(backoff_factor=1.1)
        gcs_file=_gcs.open(
            filename, 'w', content_type='text/plain', options={
                'x-goog-meta-foo': 'foo', 'x-goog-meta-bar': 'bar'},
                 retry_params=write_retry_params) 
        gcs_file.write('abcd\n')
        gcs_file.write('f'*1024*4 + '\n')
        gcs_file.close()
        self.tmp_filenames_to_clean_up.append(filename)

错误信息：
