memstore

memstore copied to clipboard

Hey, I just run the example, but not work.

package main

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

	"github.com/quasoft/memstore"
)

func main() {
	// Create a memory store, providing authentication and
	// encryption key for securecookie
	store := memstore.NewMemStore(
		[]byte("authkey123"),
		[]byte("enckey12341234567890123456789012"),
	)

	http.HandleFunc("/hello", func(w http.ResponseWriter, r *http.Request) {
		// Get session by name.
		session, err := store.Get(r, "session1")
		if err != nil {
			log.Printf("Error retrieving session: %v", err)
		}

		// The name should be 'foobar' if home page was visited before that and 'Guest' otherwise.
		user, ok := session.Values["username"]
		if !ok {
			user = "Guest"
		}
		fmt.Fprintf(w, "Hello %s", user)
	})

	http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		// Get session by name.
		session, err := store.Get(r, "session1")
		if err != nil {
			log.Printf("Error retrieving session: %v", err)
		}

		// Add values to the session object
		session.Values["username"] = "foobar"
		session.Values["email"] = "[email protected]"

		// Save values
		err = session.Save(r, w)
		if err != nil {
			log.Fatalf("Error saving session: %v", err)
		}
	})

	log.Printf("listening on http://%s/", "127.0.0.1:8000")
	log.Fatal(http.ListenAndServe("127.0.0.1:8000", nil))
}

>Output

curl http://127.0.0.1:8000/
>>>
curl http://127.0.0.1:8000/hello
>>>
Hello Guest%

What happened?

Don't have a suitable environment to test right now, but can you also try with a browser instead of separate curl commands?

The library uses gorilla/sessions to keep track of the session, so my first guess it that fails to work for separate curl commands.

emm..It work indeed in the browser. I find the session info store in browser cookies. I want to use terminal command in my case, so I need a pure memory struct like map to act as the session store.

If you also want memory storage on the client side you can simulate it by saving the received cookies for the first curl command with something like: curl -c cookies.txt http://example.com

and then reading them from the file and feeding them to the second curl command: curl -b cookies.txt http://example.com/somepage

This is not tested at all, just giving a vague idea. Might not be suitable for your usecase at all.

ok, thank you, let me have a try.
