How to set an api prefix in a flask application?

Question

I'm using this way to set it

app = Flask(__name__)
app.config['APPLICATION_ROOT'] = "/api"

@app.route("/posts")
def posts():
    ...
    return response, 200

I want to get the endpoint as:

http://localhost:5000/api/posts

But can't show correctly. Got 404 Not Found error.

If use @app.route("/api/posts"), it works.

APPLICATION_ROOT is a builtin feature, why it doesn't work?

That's not what APPLICATION_ROOT does. See: https://stackoverflow.com/questions/18967441/add-a-prefix-to-all-flask-routes — rdas, May 25 '21 at 05:49

You have to set the SCRIPT_NAME env var with your prefix.

Please note, this is a WSGI server feature, and thus the Flask development server ignores it.
