golang google oauth2 - not able to get user info (library : https://github.com/golang/oauth2)

i am using the following library for google oauth2 https://github.com/golang/oauth2

I am using the code given in the examples (url : http://play.golang.org/p/qXyuaVEhyS ,https://godoc.org/golang.org/x/oauth2/google )

I am able to get the auth code and token , but not able to make a get request to get user info

MyCode :

conf := &oauth2.Config{
		ClientID:     "my client id",
		ClientSecret: "secred id",
		RedirectURL:  "http://localhost:3000/googlelogin",
		Scopes: []string{
			"https://www.googleapis.com/auth/userinfo.profile",
		},
		Endpoint: google.Endpoint,
	}

m.Get("/googleloginrequest", func(r render.Render, request *http.Request) {

	url := conf.AuthCodeURL("state")
	fmt.Printf("Visit the URL for the auth dialog: %v", url)

	r.Redirect(url)

})

m.Get("/googlelogin", func(r render.Render, request *http.Request) {

		authcode := request.FormValue("code")

		tok, err := conf.Exchange(oauth2.NoContext, authcode)
		if err != nil {
			log.Fatal(err)
		}
		
		client := conf.Client(oauth2.NoContext, tok)

		resp, err :=client.Get("https://www.googleapis.com/userinfo/v2/me")
		
		r.JSON(200, map[string]interface{}{"status":resp})
	})

the response i get here is very big and does not have any user info

response :

Please help, or suggest me other working library/code ,which works in the above scenario

this Library works for me "golang.org/x/oauth2/google"

Initiatialization

googleconf = &oauth2.Config{
		ClientID:     "your-client-id",
		ClientSecret: "youe-secred",
		RedirectURL:  "http://localhost:300/googlelogin",
		Scopes: []string{
			"https://www.googleapis.com/auth/userinfo.profile",
			"https://www.googleapis.com/auth/userinfo.email",
		},
		Endpoint: google.Endpoint,
	}

Redirect User on Request :

url := googleconf.AuthCodeURL("state")
response.Redirect(url)

Getting Data From Google :

    authcode := request.FormValue("code")

	tok, err := googleconf.Exchange(oauth2.NoContext, authcode)
	if err != nil {
		fmt.Println("err is", err)
	}

	fmt.Println("token is ", tok)
	response, err := http.Get("https://www.googleapis.com/oauth2/v2/userinfo?access_token=" + tok.AccessToken)

    defer response.Body.Close()
    contents, err := ioutil.ReadAll(response.Body)
