无法激活 Django 和 Nginx 的 HTTPS 链接

Question

我有一个 Django Rest 框架应用程序在安全的 Nginx 服务器上运行。 当我在 DRF API 上导航时，导航栏中的协议会很好地重定向到 https。 我的问题是所有生成的 URL 都是 http 而不是 https。 我在代码中看到，不同的URL都是用这个方法构建的：

def build_absolute_uri(self, location=None):
        """
        Build an absolute URI from the location and the variables available in
        this request. If no ``location`` is specified, build the absolute URI
        using request.get_full_path(). If the location is absolute, convert it
        to an RFC 3987 compliant URI and return it. If location is relative or
        is scheme-relative (i.e., ``//example.com/``), urljoin() it to a base
        URL constructed from the request variables.
        """
        if location is None:
            # Make it an absolute URL (but schemeless and domainless) for the
            # edge case that the path starts with '//'.
            location = '//%s' % self.get_full_path()
        bits = urlsplit(location)
        if not (bits.scheme and bits.netloc):
            current_uri = '{scheme}://{host}{path}'.format(scheme=self.scheme,
                                                           host=self.get_host(),
                                                           path=self.path)
            # Join the constructed URL with the provided location, which will
            # allow the provided ``location`` to apply query strings to the
            # base path as well as override the host, if it begins with //
            location = urljoin(current_uri, location)
        return iri_to_uri(location)

就我而言，此方法始终返回不安全的 URL（HTTP 而不是 HTTPS）。 我已经按照这篇文章中的描述编辑了我的设置： https://security.stackexchange.com/questions/8964/trying-to-make-a-django-based-site-use-https-only-not-sure-if-its-secure 但生成的 URL 仍然是 HTTP。 这是我的 Nginx 配置：

server {
        listen 80;
        listen [::]:80;

        server_name backend.domaine.na.me www.backend.domaine.na.me server_ip:8800;

        return 301 https://$server_name$request_uri;
}

server {
        # SSL configuration

        listen 443 ssl http2;
        listen [::]:443 ssl http2;
        include snippets/ssl-backend.domaine.na.me.conf;
        include snippets/ssl-params.conf;

        location / {
                proxy_pass http://server_ip:8800/;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto https;
                proxy_set_header Host $http_host;
                proxy_redirect off;
        }
}


server {
        listen 8800;
        server_name server_ip;
        location = /favicon.ico { access_log off; log_not_found off; }

        location /static/ {
                root /projects/my_django_app;
        }

        location /media/ {
                root /projects/my_django_app;
        }

        location / {
                include proxy_params;
                proxy_pass http://unix:/projects/my_django_app.sock;
        }

        location ~ /.well-known {
                allow all;
        }
}

还有我的 Django 配置：

在

wsgi.py

：

os.environ['HTTPS'] = "on"
os.environ['wsgi.url_scheme'] = "https"

在

settings.py

（注意：我已经尝试了前两行）：

#SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
SECURE_PROXY_SSL_HEADER = ('HTTP_X_SCHEME', 'https')
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True

我真的需要解决这个问题，因为我的 DRF API 返回一些图像 URL，该 URL 必须是 HTTPS，否则该网站不能被视为 100% 安全。

我的配置有什么问题吗？我是否缺少一些选项？

不需要间接；您可以合并 SSL 块和 :8800 块中的设置，得到如下所示的内容：

server {
        listen 80;
        listen [::]:80;

        server_name backend.domaine.na.me www.backend.domaine.na.me;

        return 301 https://$server_name$request_uri;
}

server {
        # SSL configuration

        listen 443 ssl http2;
        listen [::]:443 ssl http2;
        include snippets/ssl-backend.domaine.na.me.conf;
        include snippets/ssl-params.conf;

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

        location /static/ {
                root /projects/my_django_app;
        }

        location /media/ {
                root /projects/my_django_app;
        }

        location ~ /.well-known {
                allow all;
        }

        location / {
                proxy_pass http://unix:/projects/my_django_app.sock;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto https;
                proxy_set_header Host $http_host;
                proxy_redirect off;
        }
}

然后，设置

SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')

，它应该可以工作。

我找不到任何有关

include proxy_params

的信息，我怀疑您在第一个代理块中设置的标头根本没有转发到 Django 应用程序。
