在 Nginx request_uri 中使用变量

Question

Good morning programmers, I'm trying to protect a file, and for that I just want to allow the request_uri that I define. Example:

if ($request_uri !~* "d=123") {
return 403;
}

In this case, that example works, but I would like to do something like this:

set $teste 123;
if ($request_uri !~* "d=$teste") {
return 403;
}

So I want to make it via variables, is that possible? Cause I already tested a bunch of examples and none of them worked.

PS: I'm using OpenResty (Nginx+Lua) so if there is a possible solution with lua I would accept it too.

Answer 1

Assuming d is your query argument and 123 is it's value, you could try something like this:

set $teste 123;
if ($request_uri ~* "[?&]d=([^&]*)") { set $d $1; }
if ($d != $teste) {
    return 403;
}
