Nginx 和 Oauth2-proxy : After logging in with Google, 重定向回 Oauth 登录页面

Question

我正在尝试使用 Oauth2-proxy 作为通过 Google 身份验证访问我的网站的网关。出现 Oauth 登录页面，您可以单击“登录”，这会将您带到 Google 登录页面，但登录后会直接重定向回 Oauth 登录页面。我怀疑它与 cookies 有关，但我不知道我哪里出错了。
NGINX 配置:

server {
  listen 443;
  server_name my.website.com;

  ssl on;
  ssl_certificate /etc/ssl/my.website.com.pem;
  ssl_certificate_key /etc/ssl/my.website.com.key;

  location /oauth2/ {
    proxy_pass       http://127.0.0.1:4180;
    proxy_set_header Host                    $host;
    proxy_set_header X-Real-IP               $remote_addr;
    proxy_set_header X-Scheme                $scheme;
    proxy_set_header X-Auth-Request-Redirect $request_uri;
  }
  location = /oauth2/auth {
    proxy_pass       http://127.0.0.1:4180;
    proxy_set_header Host             $host;
    proxy_set_header X-Real-IP        $remote_addr;
    proxy_set_header X-Scheme         $scheme;
    proxy_set_header Content-Length   "";
    proxy_pass_request_body           off;
  }

  location / {
    auth_request /oauth2/auth;
    error_page 401 = /oauth2/sign_in;

    # pass information via X-User and X-Email headers to backend,
    # requires running with --set-xauthrequest flag
    auth_request_set $user   $upstream_http_x_auth_request_user;
    auth_request_set $email  $upstream_http_x_auth_request_email;
    proxy_set_header X-User  $user;
    proxy_set_header X-Email $email;

    # if you enabled --pass-access-token, this will pass the token to the backend
    auth_request_set $token  $upstream_http_x_auth_request_access_token;
    proxy_set_header X-Access-Token $token;

    # if you enabled --cookie-refresh, this is needed for it to work with auth_request
    auth_request_set $auth_cookie $upstream_http_set_cookie;
    add_header Set-Cookie $auth_cookie;

    # When using the --set-authorization-header flag, some provider's cookies can exceed the 4kb
    # limit and so the OAuth2 Proxy splits these into multiple parts.
    # Nginx normally only copies the first `Set-Cookie` header from the auth_request to the respon$
    # so if your cookies are larger than 4kb, you will need to extract additional cookies manually.
    auth_request_set $auth_cookie_name_upstream_1 $upstream_cookie_auth_cookie_name_1;

    # Extract the Cookie attributes from the first Set-Cookie header and append them
    # to the second part ($upstream_cookie_* variables only contain the raw cookie content)
    if ($auth_cookie ~* "(; .*)") {
        set $auth_cookie_name_0 $auth_cookie;
        set $auth_cookie_name_1 "auth_cookie_name_1=$auth_cookie_name_upstream_1$1";
    }

    # Send both Set-Cookie headers now if there was a second part
    if ($auth_cookie_name_upstream_1) {
        add_header Set-Cookie $auth_cookie_name_0;
        add_header Set-Cookie $auth_cookie_name_1;
    }
    
    proxy_set_header   X-Forwarded-For $remote_addr;
    proxy_set_header   Host $http_host;
    proxy_pass         "http://127.0.0.1:8888"; # This is where my web server is hosted
  }
}

Oauth2-代理配置:

cookie_secret="" # Filled in with a base64 string
provider="google"
email_domains="*"
client_secret="" # Filled in with Google auth client secret
client_id="" # Filled in with Google auth client ID
cookie_secure="false" # No idea what to set this as, tried both false and true, same result
redirect_url="https://my.website.com/oauth2/auth/"
upstreams="http://127.0.0.1:8888/" # My website server

Oauth2-proxy 启动命令:

~/oauth2-proxy-v6.1.1.linux-amd64/oauth2-proxy --config=/home/username/work/src/github.com/oauth2-proxy/oauth2-proxy/contrib/local-environment/oauth2-proxy.cfg

任何想法将不胜感激!

根据documentation
--redirect-url 是 OAuth 重定向 URL，应设置为支持的回调端点，例如“https://internalapp.yourcompany.com/oauth2/callback”。
/oauth2/callback endpoint - 在 OAuth 周期结束时使用的 URL。 oauth 应用程序将以此配置为回调 url。
实际生成的 url 有一个 state 参数，其中包括要返回的原始 URL。
据我了解，回调从状态中检索原始(受代理保护)url 并将浏览器重定向到它。
