我知道如何将保存到文本文件的字符串上传到 Google Cloud Storage:使用upload_blob下面的函数(来源):
from google.cloud import storage
def upload_blob(bucket_name, source_file_name, destination_blob_name):
"""Uploads a file to the bucket."""
# The ID of your GCS bucket
# bucket_name = "your-bucket-name"
# The path to your file to upload
# source_file_name = "local/path/to/file"
# The ID of your GCS object
# destination_blob_name = "storage-object-name"
storage_client = storage.Client()
bucket = storage_client.bucket(bucket_name)
blob = bucket.blob(destination_blob_name)
blob.upload_from_filename(source_file_name)

我可以创建一个存储在本地磁盘上的文件:
!touch localfile
!echo "contents of my file" > localfile
!cat localfile # outputs: contents of my file

将此文件上传到 Google 云存储:
upload_blob('my-project','localfile','gcsfile')

确实已上传:
如何gcsfile在 Google Cloud Storage 中创建包含 string 的内容contents of my file,而不先保存它?
我试过:
import io
output = io.BytesIO()
output.write(b'First line.\n')
upload_blob('adventdalen-003',output,'out')

不起作用,我得到:
TypeError: expected str, bytes or os.PathLike object, not _io.BytesIO

相似但不同的线程:
这些都不是 Python 中的。

使用@johnhanley的建议,这是实现 blob.upload_from_string() 的代码:
from google.cloud import storage
def write_to_blob(bucket_name,file_name):
storage_client = storage.Client()
bucket = storage_client.bucket(bucket_name)
blob = bucket.blob(file_name)
blob.upload_from_string("written in python")
write_to_blob(bucket_name="test-bucket",file_name="from_string.txt")

保存在 Google 云存储中:
里面from_string.txt:
