How do I set response headers in Flask?

Question

This is my code:

@app.route(\'/hello\', methods=[\"POST\"])
def hello():
    resp = make_response()
    resp.headers[\'Access-Control-Allow-Origin\'] = \'*\'         


        

Answer 1

This work for me

from flask import Flask
from flask import Response

app = Flask(__name__)

@app.route("/")
def home():
    return Response(headers={'Access-Control-Allow-Origin':'*'})

if __name__ == "__main__":
    app.run()
