在我看来，我不太了解 REMOTE_USER 变量。我有三个基于不同主机的实例：nginx、django_auth_server、django_app_server。我正在尝试实现“单点登录”：用户通过 nginx 登录到 django_auth_server，被重定向到 django_app_server 并继续冲浪而无需身份验证。在我重定向到根文件夹后（从“/login”到“/”），REMOTE_USER 变量为空。但它确实存在于请求标头中：

Content-Type: text/html; charset=utf-8
Location: /
REMOTE_USER: alfabeta
X-Frame-Options: SAMEORIGIN
Vary: Cookie
Content-Length: 0
Set-Cookie:  csrftoken=...
Set-Cookie:  sessionid=...

授权视图中的代码（djangoauth 实例）：

        if user is not None:
            login(request, user)
            r = redirect('/')
            r['REMOTE_USER'] = username
            return r

我不确定以这种方式设置变量是否正确。

nginx 配置的一部分

server {
  listen 8080 default_server; 
  server_name localhost;
  charset     utf8;
  autoindex   off;

  underscores_in_headers on;
  proxy_pass_request_headers on;
  ...

  location / {
    include /etc/nginx/uwsgi_params;
    uwsgi_pass uwsgiapp;
    uwsgi_read_timeout 300;

    uwsgi_param Host $host;
    uwsgi_param X-Real-IP $remote_addr;
    uwsgi_param X-Forwarded-For $proxy_add_x_forwarded_for;
    uwsgi_param X-Forwarded-Proto $http_x_forwarded_proto;

  }

  location =/login/ {
    include /etc/nginx/uwsgi_params;
    uwsgi_pass uwsgiauth;
    uwsgi_read_timeout 300;

    uwsgi_param Host $host;
    uwsgi_param X-Real-IP $remote_addr;
    uwsgi_param X-Forwarded-For $proxy_add_x_forwarded_for;
    uwsgi_param X-Forwarded-Proto $http_x_forwarded_proto;

    uwsgi_param REMOTE_USER $remote_user;
  }

如何将变量传递给应用服务器？
