如何使 GCP 上的 Flask API 在 https 而不是 http 上运行

Question

I have a flask API which is running on a google VM instance but currently it is running on http. So for instance, http://36.137.283.44:5000/get_values is the url for one endpoint where 36.137.283.44 is the external IP of the VM instance and 5000 is the port. I just want to the http to become https.

I've seen some answers which use load balancers and others which add ssl related code in the app.py file itself but neither seem to work.

Answer 1

You need to have the SSL certificate to run flask on https. Once you have the private key and certificate pem files for the SSL. Copy it to the folder where you are the running the python API. Say you copied over the cert.pem and key.pem , to the API code folder then change the API code for the following line to below.

application.run(host="0.0.0.0",
                port=5000,
                debug=True,
                ssl_context=("cert.pem", "key.pem"))

If you hit the IP after this you might get safety error as the certificate is issued for a certain domain name, try calling with the same.
