Goth-Fiber: Multi-Provider Authentication for Go 
Is wrapper for goth library to use with fiber Framework, provides a simple, clean, and idiomatic way to write authentication packages for Go web applications.
Unlike other similar packages, Goth, lets you write OAuth, OAuth2, or any other
protocol providers, as long as they implement the Provider
and Session
interfaces.

Examples
See the examples folder for a working application that lets users authenticate through Twitter, Facebook, Google Plus etc.
To run the example either clone the source from GitHub
$ git clone git@github.com/Noooste/goth_fiber.git
$ go get github.com/Noooste/goth_fiber
$ cd goth_fiber/examples
$ go get -v
$ go build
$ ./examples
Now open up your browser and go to http://localhost:8088/login/google to see the example.
To actually use the different providers, please make sure you set environment variables. Example given in the examples/main.go file
Security Notes
By default, goth_fiber uses a Session
from the gofiber/session
package to store session data.
As configured, goth will generate cookies with the following session.Config
:
session.Config{
Expiration: 24 * time.Hour,
Storage: memory.New(),
KeyLookup: "cookie:_gothic_session",
CookieDomain: "",
CookiePath: "",
CookieSecure: false,
CookieHTTPOnly: true,
CookieSameSite: "Lax",
KeyGenerator: utils.UUIDv4,
}
To tailor these fields for your application, you can override the goth_fiber.SessionStore
variable at startup.
The following snippet shows one way to do this:
// optional config
config := session.Config{
Expiration: 30 * time.Minutes,
Storage: sqlite3.New(), // From github.com/gofiber/storage/sqlite3
KeyLookup: "header:session_id",
CookieDomain: "google.com",
CookiePath: "/users",
CookieSecure: os.Getenv("ENVIRONMENT") == "production",
CookieHTTPOnly: true, // Should always be enabled
CookieSameSite: "Lax",
KeyGenerator: utils.UUIDv4,
}
// create session handler
sessions := session.New(config)
goth_fiber.SessionStore = sessions

Constants ¶
const ProviderParamKey key = iota
ProviderParamKey can be used as a key in context when passing in a provider
Variables ¶
var ( SessionStore *session.Store ErrSessionNil = errors.New("goth/gothic: no SESSION_SECRET environment variable is set. The default cookie store is not available and any calls will fail. Ignore this warning if you are using a different store") )
Session can/should be set by applications using gothic. The default is a cookie store.
Functions ¶
func BeginAuthHandler ¶
func BeginAuthHandler(ctx fiber.Ctx) error
BeginAuthHandler is a convenience handler for starting the authentication process. It expects to be able to get the name of the provider from the query parameters as either "provider" or ":provider".
BeginAuthHandler will redirect the user to the appropriate authentication end-point for the requested provider.
See https://github.com/markbates/goth/examples/main.go to see this in action.
func CompleteUserAuth ¶
func CompleteUserAuth(ctx fiber.Ctx, options ...CompleteUserAuthOptions) (goth.User, error)
CompleteUserAuth does what it says on the tin. It completes the authentication process and fetches all of the basic information about the user from the provider.
It expects to be able to get the name of the provider from the query parameters as either "provider" or ":provider".
This method automatically ends the session. You can prevent this behavior by passing in options. Please note that any options provided in addition to the first will be ignored.
See https://github.com/markbates/goth/examples/main.go to see this in action.
func GetAuthURL ¶
GetAuthURL starts the authentication process with the requested provided. It will return a URL that should be used to send users to.
It expects to be able to get the name of the provider from the query parameters as either "provider" or ":provider".
I would recommend using the BeginAuthHandler instead of doing all of these steps yourself, but that's entirely up to you.
func GetContextWithProvider ¶
func GetContextWithProvider(ctx fiber.Ctx, provider string) fiber.Ctx
GetContextWithProvider returns a new request context containing the provider
func GetFromSession ¶
GetFromSession retrieves a previously-stored value from the session. If no value has previously been stored at the specified key, it will return an error.
func GetProviderName ¶
GetProviderName is a function used to get the name of a provider for a given request. By default, this provider is fetched from the URL query string. If you provide it in a different way, assign your own function to this variable that returns the provider name for your request.
func GetState ¶
func GetState(ctx fiber.Ctx) string
GetState gets the state returned by the provider during the callback. This is used to prevent CSRF attacks, see http://tools.ietf.org/html/rfc6749#section-10.12
func SetState ¶
func SetState(ctx fiber.Ctx) string
SetState sets the state string associated with the given request. If no state string is associated with the request, one will be generated. This state is sent to the provider and can be retrieved during the callback.
func StoreInSession ¶
StoreInSession stores a specified key/value pair in the session.
Types ¶
type CompleteUserAuthOptions ¶
type CompleteUserAuthOptions struct { // True if CompleteUserAuth should automatically end the user's session. // // Defaults to True. ShouldLogout bool }
CompleteUserAuthOptions Options that affect how CompleteUserAuth works.
