auth0.NewValidator not enough args

[neophiliac]

Following the instructions in the README, I get

$ go run main.go

command-line-arguments

./main.go:50:34: not enough arguments in call to auth0.NewValidator
have (auth0.Configuration)
want (auth0.Configuration, auth0.RequestTokenExtractor)

Passing nil for the missing parameter seems to work.

Passing nil as parameter results in an error:

square/go-jose: compact JWS format must have three parts
Token is not valid: <nil>

auth0 provides some helpers for it

"github.com/auth0-community/go-auth0"
"gopkg.in/square/go-jose.v2/jwt"

type jwtHeaderExtractor struct {}

func (e *jwtHeaderExtractor) Extract(r *http.Request) (*jwt.JSONWebToken, error) {
	return auth0.FromHeader(r)
}

client := auth0.NewJWKClient(auth0.JWKClientOptions{URI: JWKS_URI}, &jwtHeaderExtractor{})

Getting the same 'Token is not valid: ' even with the suggested jwtHeaderExtractor. New to auth0 and unfamiliar with the NewJWKClient call as opposed to validator.ValidateRequest. If there's a straightforward fix for this can someone post a pull request?

Using the JWKClient should fix the problem:

auth0Domain := your_auth0_domain
jwkClient := auth0.NewJWKClient(auth0.JWKClientOptions{URI: fmt.Sprintf("%s.well-known/jwks.json", auth0Domain)}, nil)
validator := auth0.NewValidator(auth0.NewConfiguration(jwkClient, []string{}, auth0Domain, jose.RS256), nil)
jwt, err := validator.ValidateRequest(yourRequest)
