How to set response headers in Python Flask?
To set response headers in Python Flask, we put the headers in the response.headers dict.
For instance, we write
@app.route("/")
def home():
resp = flask.Response("Foo bar baz")
resp.headers['Access-Control-Allow-Origin'] = '*'
return resp
to create a response with the flask.Response class by calling it with the response body.
Then we add the Access-Control-Allow-Origin response header with
resp.headers['Access-Control-Allow-Origin'] = '*'
And then we return resp as the response.
