nginx: redirect to named location inside if block

  • 772

I have a location in nginx where GET and POST requests should go to different named locations. But this code doesn't work:

if ( $request_method = GET ) {
try_files /NON-EXISTENT @named_location_get
}

if ( $request_method = POST ) {
try_files /NON-EXISTENT @named_location_post
}

Because try_files is not allowed inside if.

Is there any other way to redirect request to named location, that would work inside if?

nginx

    I don't know where this is documented, but I have seen configurations where a variable is used following the @ symbol, to make the named location conditional.

    Use this with a map block and you can eliminate the if blocks.

    I have tested this example:

    map $request_method $name {
    GET      named_location_get;
    POST     named_location_post;
    default  named_location_other;
}
server {
    ...
    location ... {
        try_files nonexistent @$name;
    }
    location @named_location_get {
        ...
    }
    ...
}
