来自类或文件的Golang大猩猩多路复用路由

Question

I'm playing around with gorilla mux and would like to set all of the application routes in a file so they don't fill up the main file with a bunch of routes. Ideally I would like to have the optional ability to even pull the routes from a database too.

Is gorilla mux the right package to use for this or is there something else to look at? Is this something that can be done?

Answer 1

gorilla mux doesn't do this, and it's not common for routing libraries in Go, since it's statically typed and compiled language.

If you have a simple 1:1 mapping of handlers, you can do this fairly easily:

// register the handlers or handler_funcs by name in a map:
handlerMap := make(map[string]*http.Handler)
// OR
handlerFuncMap := make(map[string]func(http.ResponseWriter, *http.Request))

handlerMap["myHandler"] = myHandler

// now you can iterate over you config values and assign them to a router
for path, handler := range routes {
    myRouter.Handler(path, handlerMap[handler])
}
