使用 Python 在 Google Cloud Storage 存储桶中创建/上传新文件
问题描述
如何使用 Python 和可用的客户端库在 Google Cloud Storage 中创建新的空文件?
How to create new empty files in Google Cloud Storage using Python with client libraries available?
或者如何使用 blob 函数upload_from_filename()"将新文件上传到选定的存储桶?要初始化 blob 对象，我们应该在云存储桶中已有文件，但我想创建一个新文件名，并从本地存储的文件中复制内容.我想用 python 来做这个.
Or how to upload a new file to a selected bucket using blob function "upload_from_filename()" ? To initialize the blob object we should have file already in the cloud bucket, but I want to create a new file name, and copy the content from the file stored locally. I want to do this using python.

解决方案
首先需要加载库
import google.cloud.storage
假设您创建了一个服务帐户并在某处加载了 JSON 文件，您需要创建一个客户端对象
Assuming you have a service account created and JSON file loaded somewhere, you need to create a client object
storage_client = google.cloud.storage.Client.from_service_account_json('JSON filepath')
那么你需要提供创建一个bucket对象
Then you need to provide the create a bucket object
bucket = storage_client.get_bucket('bucket_name')
现在定义存储桶中的路径和文件名
Now define the path within your bucket and the file name
d = 'path/name'
blob 方法创建新文件，也是一个对象.
The blob method create the new file, also an object.
d = bucket.blob(d)
upload_from_string 方法添加文件的内容.还有其他方法可以让您执行不同的任务.
The upload_from_string method add the contents of the file. There are other methods allowing you to perform different tasks.
d.upload_from_string('V')
第一次准备好前几个步骤所需的时间最长.
The first few steps take the longest to be ready the first time.
祝你好运！
