寻求可行的301重定向方案：HTTP转HTTPS、非www转www

Got it, let's get you sorted with the exact 301 redirect rules you need — all variants of your domain will point to https://www.domain.tld/ as required. Below are configurations for the two most common web servers:

Apache (using .htaccess or httpd.conf) #

If you're running Apache, add these rules to your root .htaccess file (or your server's virtual host config):

# Enable rewrite engine
RewriteEngine On

# Redirect HTTP (both bare and www) to HTTPS + www
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://www.domain.tld/$1 [R=301,L]

# Redirect HTTPS bare domain to HTTPS + www
RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} ^domain.tld$ [NC]
RewriteRule ^(.*)$ https://www.domain.tld/$1 [R=301,L]

• RewriteEngine On turns on Apache's URL rewriting module (make sure this module is enabled on your server first).
• The first rule catches any HTTP request (whether it's http://domain.tld or http://www.domain.tld) and redirects it to the HTTPS + www version.
• The second rule handles the case where someone accesses the HTTPS bare domain (https://domain.tld) and sends them to the www variant.
• Don't forget to replace domain.tld with your actual domain name!

Nginx #

For Nginx, add these rules to your server block configuration (usually found in /etc/nginx/sites-available/ or similar):

# Redirect HTTP bare domain to HTTPS + www
server {
    listen 80;
    server_name domain.tld;
    return 301 https://www.domain.tld$request_uri;
}

# Redirect HTTP www domain to HTTPS + www
server {
    listen 80;
    server_name www.domain.tld;
    return 301 https://www.domain.tld$request_uri;
}

# Redirect HTTPS bare domain to HTTPS + www
server {
    listen 443 ssl;
    server_name domain.tld;
    # Include your SSL certificate config here (ssl_certificate, ssl_certificate_key)
    return 301 https://www.domain.tld$request_uri;
}

# Your main HTTPS + www server block
server {
    listen 443 ssl;
    server_name www.domain.tld;
    # Add your SSL config, root directory, index files, and other site settings here
}

• Each server block targets a specific domain variant and sends a 301 redirect to the desired https://www.domain.tld URL.
• Make sure your SSL certificates cover both domain.tld and www.domain.tld (a wildcard cert or SAN cert works here).

Quick Test Tip #

After setting up the rules, you can verify they work using curl in your terminal:

curl -I http://domain.tld
curl -I http://www.domain.tld
curl -I https://domain.tld

Each should return a 301 Moved Permanently status code pointing to https://www.domain.tld/.
