Allowing access to hidden folder from web. Plotly-dash

Question

I think my question can be confusing, but I’ll explain it better.

What I want is to have my app return files located in hidden directories using http requests, for instance if I make a http://mywebsite.com/assets/style.css request I get the style.css file but, I also want to have my app return files from a hidden directory, say http://mywebsite.com/.hidden-folder/file (in this case I get a 200 response but without the file requested)

This is a kind of a new problem for me since I am not familiarized with web development, so I don’t know where to start.

Why am I asking this?

I am using certbot for enabling https in my website and I need to allow access to .well-known/acme-challenge/ folder from web and also I am curious.

This might help you

directory structure

├── api
│   ├── app.py
│   ├── __init__.py
├── build
│   ├── .hidden
│   │   └── test.json

#app.py
app = Flask(__name__,static_folder='../build',static_url_path="/")

@app.route('/hidden/<filename>')
def hello_world2(filename):
    return app.send_static_file(os.path.join(".hidden", filename))

# or

@app.route('/<path>/<filename>')
def hello_world3(path, filename):
    return app.send_static_file(os.path.join(path, filename))

>> curl 127.0.0.1:5000/hidden/test.json
{
  "test": "test"
}

>> curl 127.0.0.1:5000/.hidden/test.json
{
  "test": "test"
}

This is an old question but I recently had the same issue, I used app.server.route to basically redirect the http01 challenge that looks for files in .well-known/acme-challenge to the correct place – in my case a relative path to a public folder. Here’s the code I added to app.py below the instantiation of app = dash.Dash(...).

import flask
# Certificate http01 challenge
@app.server.route("/.well-known/acme-challenge/<path:filename>")
def http01_respond(filename):
    return flask.send_file(
        "../../public/.well-known/acme-challenge/{}".format(filename)
    )

This works on Dash 2.7.1.

This is similar to the post above, but the Flask/Dash differences weren’t obvious to me as a novice!

I wrote a post here about it in a bit more detail, but I think the above will suffice for anyone else who gets stuck like I did.
