I understand that you want to derive the bucket
and file
names from a downloadURL
.
If you look at the format of a downloadURL
you will find that it is composed as follows:
https://firebasestorage.googleapis.com/v0/b/<your-project-id>.appspot.com/o/<your-bucket-name>%2F<your-file-name>?alt=media&token=<a-token-string>
So you just need to use a set of Javascript methods like indexOf()
, substring()
and/or slice()
to extract the bucket and file names from the downloadURL
.
Then you could do something like the following, according to https://cloud.google.com/nodejs/docs/reference/storage/2.0.x/File:
const {Storage} = require('@google-cloud/storage');
const storage = new Storage();
const bucket = storage.bucket('<your-bucket-name>');
const file = bucket.file('<your-file-name>');
