goji/httpauth

httpauth currently provides HTTP Basic Authentication middleware for for Go.

Note that httpauth is completely compatible with Goji, a minimal web framework for Go, but as it satisfies http.Handler it can be used beyond Goji itself.

Example

httpauth provides a SimpleBasicAuth function to get you up and running. Particularly ideal for development servers.

Note that HTTP Basic Authentication credentials are sent over the wire "in the clear" (read: plaintext!) and therefore should not be considered a robust way to secure a HTTP server. If you're after that, you'll need to use SSL/TLS ("HTTPS") at a minimum.

This version is forked by Gerhard Häring gh@ghaering.de to use a callback thet checks username/password instead of a single valid username/password combination.

Goji

package main

import(
    "net/http"

    "github.com/zenazn/goji/web"
    "github.com/zenazn/goji/web/middleware"
)

func main() {

    goji.Use(httpauth.SimpleBasicAuth(func(user string, password string) bool {
			return user == "dave" && password == "secret"
		}))
    goji.Use(SomeOtherMiddleware)
    // myHandler requires HTTP Basic Auth
    goji.Get("/thing", myHandler)

    goji.Serve()
}

If you're looking for a little more control over the process, you can instead pass a httpauth.AuthOptions struct to httpauth.BasicAuth instead. This allows you to:

• Configure the authentication realm
• Provide your own UnauthorizedHandler (anything that satisfies http.Handler) so you can return a better looking 401 page.

func main() {

    authOpts := httpauth.AuthOptions{
        Realm: "DevCo",
        AuthFunc: func(user string, password string) bool {
			return user == correctUser && password == correctPassword
		},
        UnauthorizedHandler: myUnauthorizedHandler,
    }

    goji.Use(BasicAuth(authOpts))
    goji.Use(SomeOtherMiddleware)
    goji.Get("/thing", myHandler)

    goji.Serve()
}

gorilla/mux

Since it's all http.Handler, httpauth works with gorilla/mux (and most other routers) as well:

package main

import (
	"net/http"

	"github.com/goji/httpauth"
	"github.com/gorilla/mux"
)

func main() {
	r := mux.NewRouter()

	r.HandleFunc("/", myHandler)
	http.Handle("/", httpauth.SimpleBasicAuth(func(user string, password string) bool {
			return user == correctUser && password == correctPassword
	})(r))

	http.ListenAndServe(":7000", nil)
}

func myHandler(w http.ResponseWriter, r *http.Request) {

	w.Write([]byte("hello"))
}

net/http

If you're using vanilla net/http:

package main

import(
	"net/http"

	"github.com/goji/httpauth"
)

func main() {
	http.Handle("/", httpauth.SimpleBasicAuth(func(user string, password string) bool {
			return user == correctUser && password == correctPassword
	})(http.HandlerFunc(hello)))
	http.ListenAndServe(":7000", nil)
}
