Middleware about goji HOT 5 CLOSED

I wasn't planning on writing either of those myself, but it should be relatively easy to adopt existing libraries and middleware for Goji—the interfaces are essentially the same as net/http and would only need minor shims if any. Let me know if you run into any difficulties.

I'd also be happy to sponsor a goji-contrib (a la martini-contrib) if that would be useful, but unfortunately I lack the time to single-handedly fill it.

@zakkwylde I'd suggest just using http://www.gorillatoolkit.org/pkg/sessions "as is", or writing some middleware that makes the session available in web.C.Env and calls session.Save after the handler returns. The benefit to using it "as is'" is that you don't have the request overhead of the session where it's not needed, although you can mitigate that by only applying the middleware to a subrouter.

You could also implement your own handler that embeds a session.

Why the session.Save(r, w) not happened after the h.ServeHTTP(w, r) in the middleware? T.T

package main

import (
    "fmt"
    "github.com/gorilla/sessions"
    "github.com/zenazn/goji"
    "github.com/zenazn/goji/web"
    "net/http"
)

func main() {
    var store = sessions.NewCookieStore([]byte("secret123"))
    goji.Use(func(c *web.C, h http.Handler) http.Handler {
        handler := func(w http.ResponseWriter, r *http.Request) {
            if c.Env == nil {
                c.Env = make(map[string]interface{})
            }
            session, _ := store.Get(r, "goji-session")
            c.Env["session"] = session
            h.ServeHTTP(w, r)
            //why this not save?  T.T
            session.Save(r, w)
        }
        return http.HandlerFunc(handler)
    })
    goji.Get("/", func(c web.C, w http.ResponseWriter, r *http.Request) {
        if session, ok := c.Env["session"].(*sessions.Session); ok {
            if count, ok := session.Values["count"]; !ok {
                session.Values["count"] = 1
            } else {
                session.Values["count"] = count.(int) + 1
            }
            //Now I have to Save it in everytime
            //session.Save(r, w)
            fmt.Fprintf(w, "count %v", session.Values["count"])
        }
    })
    goji.Serve()
}

Because likely h.ServeHTTP(w, r) has already written content to the response and you can't set cookie header after this happens.

I have done a workaround for this, you can have a look at my project here:

https://github.com/elcct/defaultproject

I am using custom handler that returns string instead of writing it directly to the response, that way I can save session after running a handler and then send that string.

I'm going to close this issue out since it hasn't seen traffic in a few months.

I've started a "Goji-contrib" organization at https://github.com/goji. There are already a couple community-contributed middlewares, and I'd be delighted to make repositories for those of you looking to write your own—just shoot me an email. There's also a community-maintained list at https://github.com/zenazn/goji/wiki/Third-Party-Libraries that you might find interesting.
