无法传播数组以作为多个参数传递

I have this:

methods := [...]string{"POST", "PUT"}
router.HandleFunc(h.makeRegisterNewUser("/api/v1/register", v)).Methods("POST", "PUT")

that works except methods is unused. If I try this:

methods := [...]string{"POST", "PUT"}
router.HandleFunc(h.makeRegisterNewUser("/api/v1/register", v)).Methods(methods...)

I get this error:

cannot use methods (type [2]string) as type []string in argument to router.HandleFunc(h.makeRegisterNewUser("/api/v1/register", v)).Methods

I can't figure this one out

You don't need the ... in methods := [...]string{"POST", "PUT"}

 methods := []string{"POST", "PUT"}

Edit: Arrays are slightly different from slices. The [...] notation creates an array while a variadic function like Methods() accepts a slice. If you really need an array you can take a slice of it using [:]:

router.HandleFunc(h.makeRegisterNewUser("/api/v1/register", v)).Methods(methods[:]...)

The confusion arises from little bit different naming in Go and other languages. The data structure that resembles an array with different length and is called as "array", "vector", "list" in miscellaneous languages in Go is called "slice". And "array" in Go is another thing - a structure of fixed length.
