how set middleware gorillas/csrf in framework gin from Go

learning gin, framework for go, i need insert a csrf token, searchin i find the gorillas utils for make csrf and other thing, but my problem is the next. this

csrfMiddleware := csrf.Protect([]byte("32-byte-long-auth-key")) 

make this type

func Protect(authKey []byte, opts ...Option) func(http.Handler) http.Handler 

and try use this middleware function whith gin, especifically:

g := gin.Default() g.Use(csrfMiddleware) ///set a middleware 

how can use middlware csrf Protect with gin??, in the doc claims to be compatible. i confussed.

with this code yes working, but I don't know if it's correct, in the doc says if middleware works correctly, csrf.Token should generate a token, else, generate nothing

type helloWorldHandler struct{} func (h helloWorldHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) { fmt.Println("entro") } func main() { r := gin.Default() csrfMiddleware := csrf.Protect([]byte("32-byte-long-auth-key")) var d helloWorldHandler r.Use(gin.WrapH(csrfMiddleware(d))) r.GET("/test/session/:id", func(c *gin.Context) { a := csrf.Token(c.Request) fmt.Println(a) c.Header("X-CSRF-Token", csrf.Token(c.Request)) }) // Listen and serve on 0.0.0.0:8080
