Auth0 in Go Martini - go

Question

I'm trying to use Auth0 with Martini in Go. I'm using their examples but I can't seem to get it working no matter what I try.
Here is my code:
package main
import (
"flag"
"github.com/go-martini/martini"
"github.com/martini-contrib/render"
"github.com/auth0/go-jwt-middleware"
"encoding/base64"
"github.com/dgrijalva/jwt-go"
"net/http"
)
func main() {
m := martini.Classic()
port := flag.String("port", "8000", "HTTP Port")
flag.Parse()
jwtMiddleware := jwtmiddleware.New(jwtmiddleware.Options{
ValidationKeyGetter: func(token *jwt.Token) (interface{}, error) {
decoded, err := base64.URLEncoding.DecodeString("<token>")
if err != nil {
return nil, err
}
return decoded, nil
},
})
m.Use(render.Renderer(render.Options{
IndentJSON: true, // Output human readable JSON
}))
m.Get("/", jwtMiddleware.Handler, func(res http.ResponseWriter, req *http.Request) { // res and req are injected by Martini
res.WriteHeader(200) // HTTP 200
})
// Get the PORT from the environment.
m.RunOnAddr(":" + *port)
}
When I run that, I get a panic that says Value not found for type http.Handler
If I change the jwtMiddleware.Handler to jwtMiddleware.HandlerWithNext, I get a panic for Value not found for type http.HandlerFunc.
Does anyone have any ideas what I'm doing wrong?

Answer 1

To use the jwt-middleware with Martini, you just have to use the CheckJWT method instead of the Handler method.
Check this example: https://github.com/auth0/go-jwt-middleware/blob/master/examples/martini-example/main.go#L27
Let me know if this helps.
Cheers!
