单值上下文(net / url)中的多值url.Parse()

I am trying to build a simple router in Go.

As I understand it url.Parse returns both an error and the parsed url, despite including both these in the assignment I am still getting the error in the title of this question

func (router *Router) Get(urlString string, callback func(Res, Req)) {
    parsedUrl, err := *url.Parse(urlString)

    router.Methods["GET"][parsedUrl] = callback
}

    Try removing the * in *url.Parse(urlString).

    func (router *Router) Get(urlString string, callback func(Res, Req)) {
        parsedUrl, err := url.Parse(urlString)
    
        router.Methods["GET"][parsedUrl] = callback
    }
    

    Playground

    Also, as the url.Parse() function returns an error, your Get() function should do something with it (preferably return it, but otherwise log it, panic etc.)
