如何在 Node.js 中使用 gs:// URI 从 Google Cloud Storage 下载对象？

Question

I have gs:// string URIs to objects in Google Cloud Storage (see this question for an explanation of what gs:// URIs mean). How do I download these objects using Node.js? Thedocs only contain examples with the bucket name and file path:

const {Storage} = require('@google-cloud/storage');
const storage = new Storage();
const myBucket = storage.bucket('my-bucket');

const file = myBucket.file('my-file');

Can I make a file directly from a gs:// URI (passed as a string), or do I need to manually parse the URI into a bucket name and file path?

What you are looking for is getting a file from the Cloud Storage using the object URI ie gs://bucket_name/file_name . The answer to this is it is not possible to do the task you are looking for. Also, the official client library for Cloud Storage in NodeJS does not provide any such method to do it. So you have to parse the object URI and first get the bucket using the Storage client, then use the bucket to get the object as mentionedhere or in this github repo.
