Original GitHub issue: https://github.com/fsouza/fake-gcs-server/issues/1751

I am having everytime my python scripts uses the blob.download_to_filename method.
I am running the fake-gcs-server using this command

docker run --rm -p 4443:4443 fsouza/fake-gcs-server -scheme http

Here below is my Python script

from google.auth.credentials import AnonymousCredentials
from google.cloud import storage
from pathlib import Path

client = storage.Client(
    credentials=AnonymousCredentials(),
    project="test",
    client_options={"api_endpoint": "http://127.0.0.1:4443"},
)
bucket = client.bucket("test-bucket")
# Create the bucket in the fake GCS server
if not bucket.exists():
    client.create_bucket("test-bucket")

# Upload all txt files from tests/data folder to the fake GCS server
data_folder = Path('tests/data')
txt_files = list(data_folder.glob('*.txt'))

for txt_file in txt_files:
    blob = bucket.blob(f'folder/{txt_file.name}')
    with open(txt_file, 'r') as f:
        blob.upload_from_string(f.read())
    print(f"Uploaded {txt_file.name} to fake GCS bucket.")

# List the Buckets
for bucket in client.list_buckets():
    print(f"Bucket: {bucket.name}\n")
    # List the Blobs in each Bucket
    for blob in bucket.list_blobs():
        print(f"Blob: {blob.name}")

        # Print the content of the Blob
        b = bucket.get_blob(blob.name)
        s = b.download_to_filename('test.json')
        print(f"Downloaded `{blob.name}")

And these are the execution logs

Uploaded file1.txt to fake GCS bucket.
Uploaded file2.txt to fake GCS bucket.
Bucket: test-bucket

Blob: folder/file1.txt

I can correctly upload files into the server, list the buckets and get blob info. But the code is stucked at download_to_filename

Here below is the error I am getting

requests.exceptions.ConnectionError: HTTPConnectionPool(host='0.0.0.0', port=4443): Max retries exceeded with url: /download/storage/v1/b/test-bucket/o/folder%2Ffile1.txt?alt=media (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x000002B43E8FA120>: Failed to establish a new connection: [WinError 10049] The requested address is not valid in its context'))

Any idea about what the error could be?

Hello.
I was having the same error too, but Blob.download_to_filename() solved it.
I just wish get_blob(...).download_to_filename(...) would work properly as this is a source of confusion.

# Does not work 🙅‍♂️
from google.cloud import storage


storage_client = storage.Client(credentials=AnonymousCredentials(), project='test')
bucket = storage_client.bucket('test-bucket')
blob = bucket.get_blob('test.txt')
with tempfile.NamedTemporaryFile() as temp_file:
    blob.download_to_filename(temp_file.name)


# Work 🙆‍♂️
from google.cloud import storage
from google.cloud.storage.blob import Blob


storage_client = storage.Client(credentials=AnonymousCredentials(), project='test')
with tempfile.NamedTemporaryFile() as temp_file:
    Blob.from_string('gs://test-bucket/test.txt', client=storage_client).download_to_filename(temp_file.name)

bucket.get_blob(...).download_to_filename(...) should work. See the examples folder: https://github.com/fsouza/fake-gcs-server/blob/main/examples/python/python.py

Yes, I am aware of the Python EXAMPLE.
But for some reason it does not work.

from google.auth.credentials import AnonymousCredentials
from google.cloud import storage
from google.cloud.storage.blob import Blob


class StorageManager:
    def __init__(self):
        self.storage_client = storage.Client(credentials=AnonymousCredentials(), project='test')

    def download(self, bucket_name: str, blob_name: str, destination: str, /) -> None:
        # bucket = self.storage_client.get_bucket(bucket_name)  # OK
        # blob = bucket.get_blob(blob_name)                     # OK
        # blob.download_to_filename(destination)                # Does not work 🤔

        # Work 🙆‍♂️
        Blob.from_string(f'gs://{bucket_name}/{blob_name}', client=self.storage_client).download_to_filename(destination)

The example is validated by GitHub Actions on every change. You can see it working here: https://github.com/fsouza/fake-gcs-server/actions/runs/13772629106/job/38514639482

Please make sure you're following the instructions in the example file, or double check how CI runs it: https://github.com/fsouza/fake-gcs-server/blob/main/ci/run-python-example.sh

@fsouza
thx.
local code to bucket.get_blob(...) to bucket.blob(...) , which cured the problem.
( Reverting to `get_blob(...)' will cause the problem to reoccur )

Sorry for the inconvenience 🙇‍♂️

storage_client = storage.Client(credentials=AnonymousCredentials(), project='test')
bucket = storage_client.bucket(bucket_name)
blob = bucket.blob(blob_name)  # rewrite `get_blob()` to `blob()`
blob.download_to_filename(destination)
