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"
)
funcmain() {
goji.Use(httpauth.SimpleBasicAuth(func(userstring, passwordstring) bool {
returnuser=="dave"&&password=="secret"
}))
goji.Use(SomeOtherMiddleware)
// myHandler requires HTTP Basic Authgoji.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.

funcmain() {
authOpts:= httpauth.AuthOptions{
Realm: "DevCo",
AuthFunc: func(userstring, passwordstring) bool {
returnuser==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"
)
funcmain() {
r:=mux.NewRouter()
r.HandleFunc("/", myHandler)
http.Handle("/", httpauth.SimpleBasicAuth(func(userstring, passwordstring) bool {
returnuser==correctUser&&password==correctPassword
})(r))
http.ListenAndServe(":7000", nil)
}
funcmyHandler(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"
)
funcmain() {
http.Handle("/", httpauth.SimpleBasicAuth(func(userstring, passwordstring) bool {
returnuser==correctUser&&password==correctPassword
})(http.HandlerFunc(hello)))
http.ListenAndServe(":7000", nil)
}
