Nginx - 将 HTTP 重定向到 HTTPS

Question

I have followed some tutorials on setting up a .Net Core server on Lightsail as well as how to set up SSL for Nginx, resulting in the following 'default' config file:

server {
    listen 80 http2 default_server;
    root /var/www/mywebsite/wwwroot;
    server_name mywebsite.com;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl http2;
    root /var/www/mywebsite/wwwroot;
    ssl_certificate /etc/letsencrypt/live/www.mywebsite.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/www.mywebsite.com/privkey.pem;
    location / {
        proxy_pass http://localhost:5000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection keep-alive;
        proxy_set_header Host $http_host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

I am currently able to connect to https://mywebsite.com and https://www.mywebsite.com , but when I try to go to the http versions, either nothing is found, or on chrome a file is downloaded with a few strange characters. Any help with this would be greatly appreciated.

Answer 1

Try this:

    
server {
    listen 80;
    listen [::]:80;
    server_name example.com www.example.com; 
    return 301 https://example.com$request_uri;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name www.example.com; 
    ssl on;
}

Answer 2

The error seemed to be caused by browsers only supporting HTTP/2 with SSL. This isn't a problem in my case because I am redirecting to the secure site, so changing line 1 of the first server block from

listen 80 http2;

to

listen 80;

Solved my problem and now the redirect works.
