View Source AshAuthentication.Strategy.Google (ash_authentication v3.12.0)
Strategy for authenticating using Google
This strategy builds on-top of AshAuthentication.Strategy.OAuth2
and
assent
.
In order to use Google you need to provide the following minimum configuration:
client_id
redirect_uri
client_secret
site
See the Google OAuth 2.0 Overview for Google setup details.
DSL Documentation
Provides a pre-configured authentication strategy for Google.
This strategy is built using the :oauth2
strategy, and thus provides all the same
configuration options should you need them.
See the Google OAuth 2.0 Overview for Google setup details.
Strategy defaults:
The following defaults are applied:
:base_url
is set to"https://www.googleapis.com"
.:authorize_url
is set to"https://accounts.google.com/o/oauth2/v2/auth"
.:token_url
is set to"/oauth2/v4/token"
.:user_url
is set to"/oauth2/v3/userinfo"
.:authorization_params
is set to[scope: "https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile"]
.:auth_method
is set to:client_secret_post
.
Schema:
:name
(atom/0
) - Required. Uniquely identifies the strategy.:client_id
- Required. The OAuth2 client ID.
Takes either a module which implements theAshAuthentication.Secret
behaviour, a 2 arity anonymous function or a string.
See the module documentation forAshAuthentication.Secret
for more information.Example:
client_id fn _, resource -> :my_app |> Application.get_env(resource, []) |> Keyword.fetch(:oauth_client_id) end
:base_url
- The base URL of the OAuth2 server - including the leading protocol (iehttps://
).
Takes either a module which implements theAshAuthentication.Secret
behaviour, a 2 arity anonymous function or a string.
See the module documentation forAshAuthentication.Secret
for more information.Example:
base_url fn _, resource -> :my_app |> Application.get_env(resource, []) |> Keyword.fetch(:oauth_site) end
:site
- Deprecated: Usebase_url
instead.:auth_method
- The authentication strategy used, optional. If not set, no authentication will be used during the access token request. The value may be one of the following::client_secret_basic
:client_secret_post
:client_secret_jwt
:private_key_jwt
Valid values are nil, :client_secret_basic, :client_secret_post, :client_secret_jwt, :private_key_jwt The default value is:client_secret_post
.
:client_secret
- The OAuth2 client secret.
Required if :auth_method is:client_secret_basic
,:client_secret_post
or:client_secret_jwt
.
Takes either a module which implements theAshAuthentication.Secret
behaviour, a 2 arity anonymous function or a string.
See the module documentation forAshAuthentication.Secret
for more information.Example:
site fn _, resource -> :my_app |> Application.get_env(resource, []) |> Keyword.fetch(:oauth_site) end
:authorize_url
- Required. The API url to the OAuth2 authorize endpoint.
Relative to the value ofsite
.
Takes either a module which implements theAshAuthentication.Secret
behaviour, a 2 arity anonymous function or a string.
See the module documentation forAshAuthentication.Secret
for more information.Example:
authorize_url fn _, _ -> {:ok, "https://exampe.com/authorize"} end
:token_url
- Required. The API url to access the token endpoint.
Relative to the value ofsite
.
Takes either a module which implements theAshAuthentication.Secret
behaviour, a 2 arity anonymous function or a string.
See the module documentation forAshAuthentication.Secret
for more information.Example:
token_url fn _, _ -> {:ok, "https://example.com/oauth_token"} end
:user_url
- Required. The API url to access the user endpoint.
Relative to the value ofsite
.
Takes either a module which implements theAshAuthentication.Secret
behaviour, a 2 arity anonymous function or a string.
See the module documentation forAshAuthentication.Secret
for more information.Example:
user_url fn _, _ -> {:ok, "https://example.com/userinfo"} end
:private_key
- The private key to use if:auth_method
is:private_key_jwt
Takes either a module which implements theAshAuthentication.Secret
behaviour, a 2 arity anonymous function or a string.
See the module documentation forAshAuthentication.Secret
for more information.:redirect_uri
- Required. The callback URI base.
Not the whole URI back to the callback endpoint, but the URI to yourAuthPlug
. We can generate the rest.
Whilst not particularly secret, it seemed prudent to allow this to be configured dynamically so that you can use different URIs for different environments.
Takes either a module which implements theAshAuthentication.Secret
behaviour, a 2 arity anonymous function or a string.
See the module documentation forAshAuthentication.Secret
for more information.:authorization_params
(keyword/0
) - Any additional parameters to encode in the request phase.
eg:authorization_params scope: "openid profile email"
The default value is[]
.:registration_enabled?
(boolean/0
) - Is registration enabled for this provider?
If this option is enabled, then new users will be able to register for your site when authenticating and not already present.
If not, then only existing users will be able to authenticate. The default value istrue
.:register_action_name
(atom/0
) - The name of the action to use to register a user.
Only needed ifregistration_enabled?
istrue
.
Because we we don't know the response format of the server, you must implement your own registration action of the same name.
See the "Registration and Sign-in" section of the module documentation for more information.
The default is computed from the strategy name eg:register_with_#{name}
.:sign_in_action_name
(atom/0
) - The name of the action to use to sign in an existing user.
Only needed ifregistration_enabled?
isfalse
.
Because we don't know the response format of the server, you must implement your own sign-in action of the same name.
See the "Registration and Sign-in" section of the module documentation for more information.
The default is computed from the strategy name, eg:sign_in_with_#{name}
.:identity_resource
- The resource used to store user identities.
Given that a user can be signed into multiple different authentication providers at once we use theAshAuthentication.UserIdentity
resource to build a mapping between users, providers and that provider's uid.
See the Identities section of the module documentation for more information.
Set tofalse
to disable. The default value isfalse
.:identity_relationship_name
(atom/0
) - Name of the relationship to the provider identities resource The default value is:identities
.:identity_relationship_user_id_attribute
(atom/0
) - The name of the destination (user_id) attribute on your provider identity resource.
The only reason to change this would be if you changed theuser_id_attribute_name
option of the provider identity. The default value is:user_id
.:icon
(atom/0
) - The name of an icon to use in any potential UI.
This is a hint for UI generators to use, and not in any way canonical. The default value is:oauth2
.
