大猩猩Mux正则表达式

I'm using the Mux package from the Golang Gorilla Toolkit for my routes.

Consider the following routes:

m.HandleFunc("/admin/install", installHandler).Methods("GET")
m.HandleFunc("/admin/^((?!install).)*$", adminHandler).Methods("GET")
m.HandleFunc("/admin", adminHandler).Methods("GET")

The problem is with the regex of the middle route - it is not interpreted, so the route will not work!

m.HandleFunc("/admin/{^((?!install).)*$}", adminHandler).Methods("GET")

With the {} curly brackets doesn't work either. It is just ignored, and treated as /admin/

Neither does:

m.HandleFunc("/admin/{_dummy:^((?!install).)*$}", adminHandler).Methods("GET")

In short, what I'm trying to achieve here is to first match the /admin/install route, and that exact route I then want to exclude from the route below, using the regex, but it doesn't work.

Is there some way to use regex with the gorilla mux package?

    It is actually possible to do this:

    m.HandleFunc(`/{_dummy:admin\/([^install]*).*}`, adminHandler).Methods("GET")
    

    Edit:

    As my answer to VonC's comment above, here a sample go app: https://play.golang.org/p/nYWNADK7Sr

    Run it on your local pc. Try the following routes:

    http://localhost:8080/admin/ - (returns "adminHandler")
    http://localhost:8080/admin/something - (returns "adminHandler")
    http://localhost:8080/admin/install - (returns "installHandler")
    

    So yes VonC, it does solve the specific problem:

    "to first match the /admin/install route, and that exact route I then want to exclude from the route below"

    But it is correct that it doesn't mean "not followed by the word, install" - this is just an alternative approach which is possible within the bounds of the re2 syntax. To simply "ignore" or exclude the word install, if it happens to show up in the url.
