如何使用firebase_admin从python中的firebase存储下载文件

Question

我使用 firebase_admin 成功地将文件上传到 Firebase 存储，如下所示：

from firebase_admin import db
from firebase_admin import credentials
from firebase_admin import storage
from uuid import uuid4

cred = credentials.Certificate('key.json')
firebase_admin.initialize_app(cred, {
    'databaseURL' : 'https:url.firebaseio.com/', 'storageBucket': 'bucket.appspot.com'
})
bucket = storage.bucket()
blob = bucket.blob("myfile.txt")
new_token = uuid4()
metadata  = {"firebaseStorageDownloadTokens": new_token}
blob.metadata = metadata
blob.download_from_filename(filename="myfile.txt")

但我的问题是我不知道如何使用 firebase_admin 模块从 firebase 存储下载文件。请告诉我一个演示代码如何使用 firebase_admin 从 firebase 存储下载该文件

您找到解决方案了吗？ 我正在尝试下载图像。我能够将字节写入 txt 文件。但是，我需要下载 url 或图片。

from firebase_admin import credentials, initialize_app, storage

cred = credentials.Certificate(r"credential_location.JSON")
initialize_app(cred, {'storageBucket': 'xxxxxxxx.appspot.com'})

source_blob_name = "pic5.jpg"
bucket_name = "xxxxxxxxx.appspot.com"

#The path to which the file should be downloaded
destination_file_name = r"localpath\file.txt"


bucket = storage.bucket()
blob = bucket.blob(source_blob_name)
blob.download_to_filename(destination_file_name)
