Can't we include vars in gorilla subrouter pathprefix?-CodePudding

I'm trying to add a subrouter to my router code :

router := mux.NewRouter()
baseRouter := router.PathPrefix("/api/v1").Subrouter()
managementRouter := baseRouter.PathPrefix("/managing/{id}").Subrouter()
managementRouter.Use(auth.ManagingMiddleware)
managementRouter.HandleFunc("/add-employees", management.AddEmployeesToOrganization).Methods("POST")

The goal is to force the client to give an id variable on each call to managementRouter functions. Although, when i send a request like this :

/api/v1/managing/627e6f7e05db3552970e1164/add-employees

... I get a 404. Am I missing something or is it just not possible ?

Ok so I found a solution in my dream last night haha

Basically the problem with the following prefix :

managementRouter := baseRouter.PathPrefix("/managing/{id}").Subrouter()

Is that the router has no way of knowing where the id field stops. So when we access an endpoint with for example this url : /api/v1/managing/627e6f7e05db3552970e1164/add-employees, the router believes that the {id} variable is literally 627e6f7e05db3552970e1164/add-employees and doesn't match any route after it.

So the solution I found is to tell the router what comes after the variable. For that, you just add a slash after the variable :

managementRouter := baseRouter.PathPrefix("/managing/{id}/").Subrouter()
