我在谷歌存储中创建了一个存储桶，并上传了一个示例文本文件并授予了所有者权限 .
使用google docs中的代码，我试图读取上传的文本文件（test.txt）并创建示例文本文件 . 我不能同时进行读/创操作 .
连接到 Cloud 存储：
bucket_name = os.environ.get(
'BUCKET_NAME', 'bucket-name-12345.appspot.com')
错误 - “NotFoundError：期待来自Google存储的状态[200] . 但获得状态404.路径：'/ bucket-name-12345.appspot.com/test'
代码：
def get_cloudstorage(self,site,start_date):
bucket_name = os.environ.get(
'BUCKET_NAME', 'bucket-name-12345.appspot.com')
log.info(" in the cloud storage get method")
bucket = '/' + bucket_name
filename = bucket + '/sample'
filename1 = bucket + '/test.txt'
self.tmp_filenames_to_clean_up = []
self.create_file(filename)
self.read_file(filename1)
# Writing a file to Cloud Storage
def create_file(self, filename):
"""Create a file."""
# self.response.write('Creating file {}\n'.format(filename))
# The retry_params specified in the open call will override the default
# retry params for this particular file handle.
log.info(" in the cloud storage create_file method")
write_retry_params = cloudstorage.RetryParams(backoff_factor=1.1)
with cloudstorage.open(
filename, 'w', content_type='text/plain', options={
'x-goog-meta-foo': 'foo', 'x-goog-meta-bar': 'bar'},
retry_params=write_retry_params) as cloudstorage_file:
cloudstorage_file.write('abcde\n')
cloudstorage_file.write('f'*1024*4 + '\n')
self.tmp_filenames_to_clean_up.append(filename)
log.info(" end of the create method ")
def read_file(self, filename):
with cloudstorage.open(filename) as cloudstorage_file:)
cloudstorage_file.seek(-1024, os.SEEK_END)
log.info(cloudstorage_file.read())
log.info('end of the read_file ')
