nginx log full proxy_pass to log

Question

Given the following location with proxy_pass, I want to log the fully qualified uri.

location ~* ^/?(foo/?.*$) {
    proxy_pass https://www.someserver.com/some-thing-else/$1;
    break;
}

So for example I'd like

https://www.originalserver.com/foo?page=5

to redirect to

https://www.someserver.com/some-thing-else/foo?page=5

which I believed to be working; I think something else later down the chain is dropping the query_string.

So I want to output to the log file exactly what it was passed to. I tried $uri, $proxy_host, and $upstream_addr but I couldn't find anything that would return the fully qualified uri

https://www.someserver.com/some-thing-else/foo?page=5

Instead I get:

proxy_host:  www.someserver.com 
upstream_addr:   123.45.67.890:443  
uri_path:    /foo   
uri_query:   page=5 

I'm really new to rewrite rules, and coming from microsoft, so I've been reading the comprehensive docs for nginx and the searching the web, but I can't find an answer for this. Any help would be greatly appreciated. Thanks.

要记录完整的请求 uri，您可以更改块log_format的内部http。将其更改为：

log_format  main  '$remote_addr - $remote_user [$time_local] "$host$request_uri" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

示例输出：
