Ueberauth.Strategy.Github (Üeberauth GitHub v0.8.3) View Source
Provides an Ueberauth strategy for authenticating with GitHub.
Setup
Create an application in Github for you to use.
Register a new application at: your github developer page
and get the client_id
and client_secret
.
Include the provider in your configuration for Ueberauth;
config :ueberauth, Ueberauth,
providers: [
github: { Ueberauth.Strategy.Github, [] }
]
Then include the configuration for GitHub:
config :ueberauth, Ueberauth.Strategy.Github.OAuth,
client_id: System.get_env("GITHUB_CLIENT_ID"),
client_secret: System.get_env("GITHUB_CLIENT_SECRET")
If you haven't already, create a pipeline and setup routes for your callback handler
pipeline :auth do
Ueberauth.plug "/auth"
end
scope "/auth" do
pipe_through [:browser, :auth]
get "/:provider/callback", AuthController, :callback
end
Create an endpoint for the callback where you will handle the
Ueberauth.Auth
struct:
defmodule MyApp.AuthController do
use MyApp.Web, :controller
def callback_phase(%{ assigns: %{ ueberauth_failure: fails } } = conn, _params) do
# do things with the failure
end
def callback_phase(%{ assigns: %{ ueberauth_auth: auth } } = conn, params) do
# do things with the auth
end
end
You can edit the behaviour of the Strategy by including some options when you register your provider.
To set the uid_field
:
config :ueberauth, Ueberauth,
providers: [
github: { Ueberauth.Strategy.Github, [uid_field: :email] }
]
Default is :id
.
To set the default 'scopes' (permissions):
config :ueberauth, Ueberauth,
providers: [
github: { Ueberauth.Strategy.Github, [default_scope: "user,public_repo"] }
]
Default is empty ("") which "Grants read-only access to public information (includes public user profile info, public repository info, and gists)"
