Usage

export FLASK_RUN_HOST=0.0.0.0 FLASK_RUN_PORT=8080

python -m micro_file_server

python -m micro_file_server --host 0.0.0.0 --port 8080

or

python micro_file_server/__main__.py

or for HTTPS:

python micro_file_server/__main__.py --cert=.cert/cert.pem --key=.cert/key.pem

Built-in development web server is secure enough, but you may install production Web server: pip install gunicorn

gunicorn micro_file_server.__main__:app --bind 0.0.0.0:8080

or for HTTPS:

gunicorn micro_file_server.__main__:app --bind 0.0.0.0:8080 --certfile=.cert/cert.pem --keyfile=.cert/key.pem

Defaults, that you can change:

export FLASK_FILENAME_MAX_LENGTH=40
