如何使用 firebase_admin 從 python 中的 firebase 存儲中下載文件

Question

我使用firebase_admin成功地將文件上傳到 firebase 存儲，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")

但我的問題是我不知道如何使用 firebase_admin 模塊從 firebase 存儲下載文件。 請告訴我演示代碼如何使用 firebase_admin 從 firebase 存儲中下載該文件

Answer 1

你找到解決方案了嗎？ 我正在嘗試下載圖像。 我能夠將字節寫入 txt 文件。 但是，我需要下載 url 或圖像。

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)

Answer 2

   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)

只需將擴展名更改為 .jpg 即可，destination_file_name = r"localpath\file.jpg"
