nginx matching similar, but wrong location

  • 772

I have a few exposed JSON scripts / programs for quick information gathering from a server. I use nginx to expose those as just raw urls. So given the following locations:

location ~ ^/api/status/? {
    rewrite ^(.*)$ /path/to/some/handler/wan.handler;
}

location ~ ^/api/status-lan/? {
    rewrite ^(.*)$ /path/to/some/handler/lan.handler;
}

Why does nginx match my status-lan call to the status location? So I can view my output from /api/status/ just fine, but if I view /api/status-lan/ I get the status location instead.

    Why does nginx match my status-lan call to the status location?

    Because the location is a regular expression, and this regular expression:

    location ~ ^/api/status/? {

    means "starts with /api/status, followed by an optional trailing slash", what comes after the match doesn't matter.

    The config should probably be:

    location ~ ^/api/status/?$ {
    rewrite ^ /path/to/some/handler/wan.handler;
}

location ~ ^/api/status-lan/?$ {
    rewrite ^ /path/to/some/handler/lan.handler;
}

    I.e. match the whole url, not just the start of it. If in doubt, turn on the rewrite log as it'll make it obvious what is happening, and why.
