Usage
You can use predefined Providers to load an identity from for example Discord:
require "code0/identities"
begin
identity = Code0::Identities::Provider::Discord.new(
{
redirect_uri: "http://localhost:8080/redirect",
client_id: "id",
client_secret: "xxxx"
}).load_identity({ code: "a_valid_code" })
rescue Code0::Error => e
puts "Error occurred while loading the identity", e
exit!
end
# Then you can use the details from the user
puts identity.provider # = :discord
puts identity.username
puts identity.identifier
# ...Or you can use a provider with multiple configured providers:
require "code0/identities"
identity_provider = Code0::Identities::IdentityProvider.new
identity_provider.add_provider(:gitlab, my_gitlab_configuration)
identity_provider.add_named_provider(:my_custom_gitlab_provider, :gitlab, my_custom_gitlab_provider_configuration)
# Now you can either use the custom "my_custom_gitlab_provider" provider
# or the "gitlab" provider
identity_provider.load_identity(:gitlab, params)
# or
identity_provider.load_identity(:my_custom_gitlab_provider, params)We also support passing in a function as a configuration instead of a hash
def get_identity
provider = Code0::Identities::Provider::Discord.new(-> { fetch_configuration })
provider.load_identity(params)
end
def fetch_configuration
# Do some database action, to dynamicly load the configuration
{
redirect_uri: "http://localhost:8080/redirect",
client_id: "some dynamic value",
client_secret: "xxxx"
}
end
