When i try run this locally with docker run (locally) i am getting the error below.. However, i have already run "pip install "flask[async]" and everything seems to be installed.... but same error! Anybody idea whats wrong? Thanks!
from flask import Flask
from flask import request
from flask import Response
import json
import commacount
app = Flask(__name__)
@app.routes('/')
async def home():
x = str(request.args.get('x'))
answer = str(commacount.commaCount(x))
await asyncio.sleep(2)
r = {
"x": x,
"answer": answer
}
reply = json.dumps(r)
response = Response(response = reply, status=200, mimetype="application/json")
response.headers['Content-Type']='application/json'
response.headers['Access-Control-Allow-Orgin']='*'
return response

RuntimeError: Install Flask with the 'async' extra in order to use async views.
172.17.0.1 - - [12/Dec/2021 04:42:36] "GET /?x=,.., HTTP/1.1" 500 -
First thing you need to use @app.route instead of @app.routes. You also need to install aioflask along with flask to overcome this RuntimeError
Check below simple example -
from flask import Flask
app = Flask(__name__)
app.env = "development"
@app.route('/')
async def home():
return {"text": "Hello!"}
if __name__ == '__main__':
app.run(debug=True)
