Simplifying the oauth2 auth flow for desktop / cli apps that have no server side.

---

While oauth works fine for apps the have a server side, I personally find it a pain to use when developing simple desktop or cli applications.
That's why needed something to turn a complete oauth flow into a one-liner (well, that's clearly exaggerated, but it's barely more).

So here's how it works !

Installation

Run go get -u github.com/nmrshll/oauth2-noserver

Try out the included example with make example

Usage

1. Create an oauth app on the website/service you want to authenticate into

You must set the redirection URL to http://127.0.0.1:14565/oauth/callback for this library to function properly.

Once done you should get credentials (client id and client secret) to use in your code.

2. From your Go program, authenticate your user like this :

func main() {
	conf := &oauth2.Config{
		ClientID:     "________________",            // also known as client key sometimes
		ClientSecret: "___________________________", // also known as secret key
		Scopes:       []string{"account"},
		Endpoint: oauth2.Endpoint{
			AuthURL:  "https://bitbucket.org/site/oauth2/authorize",
			TokenURL: "https://bitbucket.org/site/oauth2/access_token",
		},
	}

	client, err := oauth2ns.AuthenticateUser(conf)
	if err != nil {
		log.Fatal(err)
	}

	// use client.Get / client.Post for further requests, the token will automatically be there
	_, _ = client.Get("/auth-protected-path")
}

The AuthURL and TokenURL can be found in the service's oauth documentation.
