【问题描述】：
我有以下代码sn-p：
import firebase_admin
from firebase_admin import credentials
from firebase_admin import storage
from google.cloud import storage
class firebase_storage():
def __init__(self, path_to_sak, root_bucket):
try:
self.cred = credentials.Certificate(path_to_sak)
firebase_admin.initialize_app(self.cred)
except Exception as e:
print("Firebase App may have already been initialized")
self.bucket = firebase_admin.storage.bucket(root_bucket)
def upload(self, key, file_path):
blob = storage.Blob(key, self.bucket)
blob.upload_from_filename(file_path)
def download(self, key, file_path):
blob = storage.Blob(key, self.bucket)
blob.download_to_filename(file_path)
def upload_string(self, key, string, mime_type):
blob = storage.Blob(key, self.bucket)
blob.upload_from_string(string, content_type=mime_type)
我正在使用 Firebase Emulators for Storage，我已验证使用方法调用 firebase_storage.download() 可以进行下载。
但是，当我尝试调用 upload() 时，会引发以下异常：
Traceback (most recent call last):
File "/usr/local/lib/python3.8/dist-packages/google/cloud/storage/blob.py", line 2348, in upload_from_file

During handling of the above exception, another exception occurred:

我的 storage.rules 如下所示：
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow write, read: if true;
}
}
}
因此，似乎允许公共读/写访问。
一切正常，我有其他模拟器（Firestore、Auth）工作正常，但存储上传拒绝工作:(
任何帮助将不胜感激谢谢！
