Compojure-specific destructuring and query strings

Question

I'm trying to access the parameter foo, using compojure, in a request like this:

/api/xyz?foo=bar 

The compojure destructuring syntax looks good, so I would like to use it. However the following just serves me the "Page not found":

(defroutes app-routes    
  (GET "/api/xyz/:foo" [foo] (str "foo: " foo))
  (route/not-found "Page not found"))

Which is kind of weird, since the verbose destructuring below works and gives me "foo: bar":

(defroutes app-routes    
  (GET "/api/xyz" {{foo :foo} :params} (str "foo: " foo))
  (route/not-found "Page not found"))

What am I missing?

Answer 1

If foo is always passed as a URL parameter, you want your code to be like this:

(defroutes app-routes    
  (GET "/api/xyz" [foo] (str "foo: " foo))
  (route/not-found "Page not found"))
