推荐答案

这就是我所使用的.希望对您有所帮助.

This is what I use. Hope it helps.

import firebase_admin
from firebase_admin import credentials
from firebase_admin import storage

# Fetch the service account key JSON file contents
cred = credentials.Certificate("credentials.json")

# Initialize the app with a service account, granting admin privileges
app = firebase_admin.initialize_app(cred, {
    'storageBucket': '<BUCKET_NAME>.appspot.com',
}, name='storage')

bucket = storage.bucket(app=app)
blob = bucket.blob("<your_blob_path>")

print(blob.generate_signed_url(datetime.timedelta(seconds=300), method='GET'))

它会生成一个公共URL (持续300秒)，供您下载文件.

It generates a public URL (for 300 secs) for you to download your files.

例如，在我的情况下，我使用该URL在django网站中使用<img>标签显示存储的图片.

For example, in my case, I use that URL to display stored pictures in my django website with <img> tag.
