使用Python在Google Cloud Storage存储桶中创建/上传新文件 [英] Creating/Uploading new file at Google Cloud Storage bucket using Python

问题描述

如何在具有客户端库的情况下使用Python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，但是我想创建一个新的文件名，然后从本地存储的文件中复制内容.我想使用python做到这一点.

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.

推荐答案

首先，您需要加载库

import google.cloud.storage

假设您已经创建了一个服务帐户并且在某个地方加载了JSON文件，则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')

然后您需要提供创建存储桶对象

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')

前几步花费的时间最长，第一次即可完成.

The first few steps take the longest to be ready the first time.

祝你好运！
