Recently at HasGeek we moved all our web application to
https. So I wanted to have all my development environment urls to have
How to have
https in flask app
from flask import Flask app = Flask(__name__) app.run('0.0.0.0', debug=True, port=8100, ssl_context='adhoc')
In the above piece of code,
ssl_context variable is passed to
werkezug.run_simple which creates SSL certificates using
OpenSSL, you may need to install
pyopenssl. I had issues with this method, so I generated self signed certificate.
Generate a private key
openssl genrsa -des3 -out server.key 1024
Generate a CSR
openssl req -new -key server.key -out server.csr
Remove Passphrase from key
cp server.key server.key.org
openssl rsa -in server.key.org -out server.key
Generate self signed certificate
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
from flask import Flask app = Flask(__name__) app.run('0.0.0.0', debug=True, port=8100, ssl_context=('/Users/kracekumarramaraju/certificates/server.crt', '/Users/kracekumarramaraju/certificates/server.key'))
ssl_context can take option
tuple of the form (cert_file, pkey_file).
In case you are using
/etc/hosts, add something similar
127.0.0.1 https://hacknight.local for accessing the web application locally.
Here is much detailed post about generating self signed certificates.
