从根本上讲,在将proxy_pass存储在变量中之后,我很难找到一种方法来删除nginx中的响应头(如果proxy_pass)。proxy_hide_header不允许我存储值。
换一种说法:
我试图访问自定义响应标头,将其保存到变量中,并摆脱它,以便它不会传播到客户端。然后在访问日志中使用该变量。不幸的是,以下内容似乎无效:
http {
log_format main '$remote_addr $http_host $destination_addr [$time_local]
"$request" $status';
access_log /opt/logs/access.log main;
server {
listen 142.133.151.129:8090 default;
##This is my internal variable for the response header field
set $destination_addr "-";
location / {
proxy_pass http://my_upstream_server;
#store the response header field
set $destination_addr $sent_http_x_destination;
#now get rid of this response header field
set $sent_http_x_destination "";
}
}
}

我正在获得$ sent_http_x_destination的空值。
这是curl请求和响应:
# curl -Ov http://142.133.151.129:8090/ao3/vod/soccer/worldcup2014/final1

有谁知道在将“ X-目标”存储并用于访问日志后如何删除它?我正在获取带有空值的“ $ destination_addr”。
谢谢
可以proxy_hide_header
用来删除从代理返回给 NGINX 的头文件,参见ngx_http_proxy_module 文档
$upstream_http_x_destination
可用于日志记录,参见ngx_http_upstream_module 文档
重写您的配置将如下所示:
http {
log_format main '$remote_addr $http_host $upstream_http_x_destination '
'[$time_local] "$request" $status';
access_log /opt/logs/access.log main;
server {
listen 142.133.151.129:8090 default;
location / {
proxy_hide_header x_destination;
proxy_pass http://my_upstream_server;
}
}
}
