无法在 Digital Ocean 上的 django Nginx 项目中将非 www 重定向到 www

Question

您好，如果有人可以帮助完成以下 Nginx 配置，我将不胜感激：

/etc/nginx/sites-available/example

server {
    server_name *.example.com;

    location = /favicon.ico { access_log off; log_not_found off; }

    location /static/ {
        alias /home/admin/pyapps/example/example/static/;
    }

    location /static/admin/ {
        alias /home/admin/pyapps/example/example/static/admin/;
    }

    location /media/ {
        root /home/admin/pyapps/example;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }


    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}


server {
    if ($host = admin.example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = backoffice.example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = www.example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    listen 80;
    server_name example.com *.example.com;
    return 404; # managed by Certbot
}

我想为 example.com 创建一个重定向到 https://www.example.com。

请注意，我正在使用 django-hosts。

我的 django-hosts 配置如下：

设置.py

ROOT_URLCONF = 'example.urls'
ROOT_HOSTCONF = 'example.hosts'
DEFAULT_HOST = 'www'
# DEFAULT_REDIRECT_URL = "http://www.example.com:8000"
DEFAULT_REDIRECT_URL = "http://www.example.com"
PARENT_HOST = 'example.com'
# HOST_PORT = '8000'

MIDDLEWARE = [
    'django_hosts.middleware.HostsRequestMiddleware',
    ....
    'django_hosts.middleware.HostsResponseMiddleware',
]

主机.py

from django.conf import settings
from django_hosts import patterns, host
from example.hostsconf import urls as redirect_urls
from . import admin_urls

host_patterns = patterns('',
    host(r'www', settings.ROOT_URLCONF, name='www'),
    host(r'admin', admin_urls, name='admin'),
    host(r'backoffice', 'backoffice.urls', name="backoffice"),
    host(r'(?!www).*', redirect_urls, name='wildcard'),
)

hostsconf/urls.py

from django.urls import path
from .views import wildcard_redirect

urlpatterns = [
    path(r'^?P<path>.*)', wildcard_redirect),
]

hostsconf/views.py

from django.conf import settings
from django.http import HttpResponseRedirect

DEFAULT_REDIRECT_URL = getattr(settings, "DEFAULT_REDIRECT_URL", "http://www.example.com")

def wildcard_redirect(request, path=None):
    new_url = DEFAULT_REDIRECT_URL
    if path is not None:
        new_url = DEFAULT_REDIRECT_URL + '/' + path
    return HttpResponseRedirect(new_url)

我几乎尝试了所有方法，但我认为这可能与 django-hosts 配置有关。

当我访问 https://example.com 时，它会向我显示“欢迎使用 nginx”屏幕，而不是重定向到 https://www.example.com。

当我访问 www.example.com 或 admin.example.com 或 backoffice.example.com 时，网站加载正常。

请有人帮助我。我想将 https://example.com 重定向到 https://www.example.com

如果您需要我提供任何其他配置，请告诉我。

Answer 1

1. 从您的第一个服务器块中删除

   example.com

   ，因为如果没有 HTTPS 子域，您将不会向该域提供任何服务。

2. 将以下 if 语句添加到第二个服务器块，将非 www 流量直接重定向到 www HTTPS 版本：

   if ($host = example.com) { return 301 https://www.example.com$request_uri; }

3. 添加包含以下内容的第三个服务器块，以将 HTTPS 流量从非 www 重定向到 www：

    server {
        if ($host = example.com) {
            return 301 https://www.example.com$request_uri;
        }
   
        server_name example.com;
        listen [::]:443;  # if you would like to support IPv6
        listen 443;
        return 404;
    }
