storage_client = Nonedef init_storage():    global storage_client    if storage_client:        return storage_client    from google.cloud import storage    if IS_EXTERNAL_PLATFORM:        storage_client = storage.Client.from_service_account_json('keys/firebase-adminsdk.json')    else:       storage_client = storage.Client()    '''    app = init_firebase()    storage_client = storage.Client(credentials=app.credential.get_credential(), project=app.project_id)    '''    return storage_client
bucket = storage_client.bucket(bucket_name=f"{PROJECT_ID}.appspot.com")


Upload and download string

from firebase_admin import storageinit_firebase()# uploadbucket = storage.bucket()blob = bucket.blob('hello.txt')blob.upload_from_string('hello world')# upload via file# blob.upload_from_filename(source_file_name)# downloadoutput = blob.download_as_string()# download to file# blob.download_to_filename(output_file_name)

Load and Save JSON

def load_json(name):    init_firebase()    bucket = storage.bucket()    blob = bucket.blob(name)    # blob.upload_from_string(json.dumps(data, indent=2))    return json.loads(blob.download_as_string())def save_json(name, data):    init_firebase()    bucket = storage.bucket()    blob = bucket.blob(name)    blob.upload_from_string(json.dumps(data, indent=2))


name = '/tmp/test.json'save_json(name, {'message': 'Hello World'})data = load_json(name)
