NGINX 无法从响应中读取自定义标头

我想从我的 nginx 服务器获取来自外部 Apache 服务器的带有自定义标头的身份验证响应。问题是，我无法获取自定义标头的值。

location /app  {
                auth_request /auth;
                add_header custom $http_x-customheader; 
       }

 location = /auth {
                    proxy_pass http://ip.externalserver/auth.php;
                    proxy_pass_request_body off;
                    proxy_set_header Content-Length "";
                    proxy_set_header X-Original-URI $request_uri;
                    proxy_set_header X-Original-METHO $request_method;
                    proxy_pass_request_headers on;

}

直接向Apache服务器请求时：

$ curl -i "http://xxxx.xxx.xxxx.xxxx/auth.php"
HTTP/1.1 200 OK
Date: Mon, 30 Sep 2019 17:08:05 GMT
Server: Apache/2.4.7 (Ubuntu)
X-Powered-By: PHP/5.5.9-1ubuntu4.29
x_customheader: 2
x-headername: headervalue
Vary: Accept-Encoding
Access-Control-Allow-Origin: *
Content-Length: 193
Content-Type: text/html

但是通过nginx：

HTTP/1.1 200 OK
Server: nginx
Date: Mon, 30 Sep 2019 16:47:28 GMT
Content-Type: application/vnd.apple.mpegurl
Content-Length: 559

ETag: "5d92319e-22f"

Cache-Control: max-age=8640000
custom: -customheader
Access-Control-Allow-Headers: *
Access-Control-Allow-Methods: GET, HEAD, OPTIONS
Access-Control-Allow-Origin: *
Accept-Ranges: bytes

我尝试过这个但没有成功：

add_header custom $http_x-customheader; 
add_header custom $http_x_customheader; 
add_header custom $upstream_http_x_customheader; 
add_header custom $upstream_http_x-customheader;

答案1

知道了：

auth_request_set $myheader $upstream_http_x_costumheader;
add_header costum $myheader;
