How do I get a SSL certificate for my WSGI Flask server so it can send data over HTTPS?
I am running a site https://coderjobmarket.com on a DigitalOcean droplet using Ubuntu 18.04 and Nginx 1.14.0. I also intend to have a Flask app using WSGI as its production server.
It would be enough to use HTTP with this server, except for a problem I have with my site: Namely, my site sends a query to the Flask server, and the browser demands the response be in HTTPS, or else it gives a “Mixed Content” error (receiving HTTP on a HTTPS site) and blocks the Flask server’s response.
The specific error message I get from my browser is this:
“Mixed Content: The page at ’https://coderjobmarket.com/results’ was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint ’http://126.96.36.199:5000/lang/vue/loc/Vancouver’. This request has been blocked; the content must be served over HTTPS.”
My question is, how can I get a SSL certificate for my Flask server so it can send data over HTTPS?
My second question is, if I use a self signed SSL certificate, will the page give me one of these warnings when it tries to load the response from the Flask server? One of these:
https://assets.digitalocean.com/articles/nginx_ssl_1604/self_signed_warning.png (Big red padlock, and the message in h1 tags, “Your connection is not private”)
If the answer is “yes, it will give every user a warning that their connection is not private,” then the Self Signed SSL Certificate option does not work for me.
