Saving OAuth2 pointer in sessions

[rhaidiz]

Describe the problem you're having
I'm trying to save a pointer into a session, specifically a OAuth2 configuration, but I'm having some issue.

Versions
go version go1.18.1 darwin/amd64

Code!
The following piece of code should reproduce the issue.
When I go to /puthandler I can see that myConf is stored in the session, but when I go to /gethandler it is nil.
I feel like I'm missing something very basic here but for the love of me I cannot figure it out.

package main

import (
	"encoding/gob"
	"fmt"
	"log"
	"net/http"

	"github.com/gorilla/sessions"
	"golang.org/x/oauth2"
)

var store = sessions.NewCookieStore([]byte("key"))

type Project struct {
	ID   string
	conf *oauth2.Config
}

func PutHandler(w http.ResponseWriter, r *http.Request) {
	sess, err := store.Get(r, "test_sess")
	if err != nil {
		http.Error(w, err.Error(), 500)
		return
	}

	myConf := &oauth2.Config{
		ClientID:     "YOUR_CLIENT_ID",
		ClientSecret: "YOUR_CLIENT_SECRET",
		Scopes:       []string{"SCOPE1", "SCOPE2"},
		Endpoint: oauth2.Endpoint{
			AuthURL:  "https://provider.com/o/oauth2/auth",
			TokenURL: "https://provider.com/o/oauth2/token",
		},
	}
	project := Project{ID: "8138ahd913", conf: myConf}
	sess.Values["proj"] = project
	err = sess.Save(r, w)
	if err != nil {
		http.Error(w, err.Error(), 500)
		return
	}

	fmt.Fprintf(w, "%#v", sess.Values)
}

func GetHandler(w http.ResponseWriter, r *http.Request) {
	sess, err := store.Get(r, "test_sess")
	if err != nil {
		http.Error(w, err.Error(), 500)
		return
	}

	fmt.Fprintf(w, "%#v", sess.Values)
}

func main() {
	gob.Register(Project{})

	http.HandleFunc("/puthandler", PutHandler)
	http.HandleFunc("/gethandler", GetHandler)

	log.Fatal(http.ListenAndServe(":8000", nil))
}

I'm an idiot.
Variable conf in struct Project is not exported and therefore cannot be serialized.
Forget I asked 😄
