是否可以使用 nginx 将 HTTPS 重定向到 HTTPS？

Question

I have the following issue. I created this danish website flaatinfo.dk that is also accessible by flåtinfo.dk.

The domain manager gave me a certificate for flaatinfo.dk but said that they could not generate one for flåtinfo.dk because it contains a special character.

Is there a way (in nginx setup) that I can redirect all HTTPS requests from flåtinfo.dk to flaatinfo.dk??

HTTP redirects seem to work fine but if I try to redirect HTTPS like this I get cert error in browser:

server {
    listen 443 ssl;
    server_name flåtinfo.dk www.flåtinfo.dk;
    return 301 https://flaatinfo.dk$request_uri;
}

Answer 1

www.flåtinfo.dk is an internationalized domain name (IDN).

According to NGINX documentation for internationalized names :

domain names (IDNs) should be specified using an ASCII (Punycode) representation in the server_name directive

So you should specify it in NGINX configuration as xn--fltinfo-fxa.dk .

As for why your plain HTTP redirect worked anyway, it's probably because it didn't match any other domain so NGINX had to eventually choose it as default.

I get cert error in browser

Naturally, since you don't have a TLS certificate for your IDN, browsers will issue warnings. You need to get a TLS certificate for IDN to get rid of the warning. Let's Encrypt supports issuing certs for IDNs and is free of charge.

在根位置的.htaccess文件中添加重定向规则
