OAuth2 Authorization Endpoint
OAuth2AuthorizationEndpointConfigurer
provides the ability to customize the OAuth2 Authorization endpoint.
It defines extension points that let you customize the pre-processing, main processing, and post-processing logic for OAuth2 authorization requests.
OAuth2AuthorizationEndpointConfigurer
provides the following configuration options:
@Bean
public SecurityFilterChain authorizationServerSecurityFilterChain(HttpSecurity http) throws Exception {
OAuth2AuthorizationServerConfigurer authorizationServerConfigurer =
new OAuth2AuthorizationServerConfigurer();
http.apply(authorizationServerConfigurer);
authorizationServerConfigurer
.authorizationEndpoint(authorizationEndpoint ->
authorizationEndpoint
.authorizationRequestConverter(authorizationRequestConverter) (1)
.authorizationRequestConverters(authorizationRequestConvertersConsumer) (2)
.authenticationProvider(authenticationProvider) (3)
.authenticationProviders(authenticationProvidersConsumer) (4)
.authorizationResponseHandler(authorizationResponseHandler) (5)
.errorResponseHandler(errorResponseHandler) (6)
.consentPage("/oauth2/v1/authorize") (7)
);
return http.build();
}
1 | authorizationRequestConverter() : Adds an AuthenticationConverter (pre-processor) used when attempting to extract an OAuth2 authorization request (or consent) from HttpServletRequest to an instance of OAuth2AuthorizationCodeRequestAuthenticationToken or OAuth2AuthorizationConsentAuthenticationToken . |
2 | authorizationRequestConverters() : Sets the Consumer providing access to the List of default and (optionally) added AuthenticationConverter 's allowing the ability to add, remove, or customize a specific AuthenticationConverter . |
3 | authenticationProvider() : Adds an AuthenticationProvider (main processor) used for authenticating the OAuth2AuthorizationCodeRequestAuthenticationToken or OAuth2AuthorizationConsentAuthenticationToken . |
4 | authenticationProviders() : Sets the Consumer providing access to the List of default and (optionally) added AuthenticationProvider 's allowing the ability to add, remove, or customize a specific AuthenticationProvider . |
5 | authorizationResponseHandler() : The AuthenticationSuccessHandler (post-processor) used for handling an “authenticated” OAuth2AuthorizationCodeRequestAuthenticationToken and returning the OAuth2AuthorizationResponse. |
6 | errorResponseHandler() : The AuthenticationFailureHandler (post-processor) used for handling an OAuth2AuthorizationCodeRequestAuthenticationException and returning the OAuth2Error response. |
7 | consentPage() : The URI of the custom consent page to redirect resource owners to if consent is required during the authorization request flow. |
OAuth2AuthorizationEndpointConfigurer
configures the OAuth2AuthorizationEndpointFilter
and registers it with the OAuth2 authorization server SecurityFilterChain
@Bean
.
OAuth2AuthorizationEndpointFilter
is the Filter
that processes OAuth2 authorization requests (and consents).
OAuth2AuthorizationEndpointFilter
is configured with the following defaults:
-
AuthenticationConverter
— ADelegatingAuthenticationConverter
composed ofOAuth2AuthorizationCodeRequestAuthenticationConverter
andOAuth2AuthorizationConsentAuthenticationConverter
. -
AuthenticationManager
— AnAuthenticationManager
composed ofOAuth2AuthorizationCodeRequestAuthenticationProvider
andOAuth2AuthorizationConsentAuthenticationProvider
. -
AuthenticationSuccessHandler
— An internal implementation that handles an “authenticated”OAuth2AuthorizationCodeRequestAuthenticationToken
and returns theOAuth2AuthorizationResponse
. -
AuthenticationFailureHandler
— An internal implementation that uses theOAuth2Error
associated with theOAuth2AuthorizationCodeRequestAuthenticationException
and returns theOAuth2Error
response.
Customizing Authorization Request Validation
OAuth2AuthorizationCodeRequestAuthenticationValidator
is the default validator used for validating specific OAuth2 authorization request parameters used in the Authorization Code Grant.
The default implementation validates the redirect_uri
and scope
parameters.
If validation fails, an OAuth2AuthorizationCodeRequestAuthenticationException
is thrown.
OAuth2AuthorizationCodeRequestAuthenticationProvider
provides the ability to override the default authorization request validation by supplying a custom authentication validator of type Consumer<OAuth2AuthorizationCodeRequestAuthenticationContext>
to setAuthenticationValidator()
.
OAuth2AuthorizationCodeRequestAuthenticationContext holds the OAuth2AuthorizationCodeRequestAuthenticationToken , which contains the OAuth2 authorization request parameters.
|
If validation fails, the authentication validator MUST throw OAuth2AuthorizationCodeRequestAuthenticationException .
|
A common use case during the development life cycle phase is to allow for localhost
in the redirect_uri
parameter.
The following example shows how to configure OAuth2AuthorizationCodeRequestAuthenticationProvider
with a custom authentication validator that allows for localhost
in the redirect_uri
parameter:
@Bean
public SecurityFilterChain authorizationServerSecurityFilterChain(HttpSecurity http) throws Exception {
OAuth2AuthorizationServerConfigurer authorizationServerConfigurer =
new OAuth2AuthorizationServerConfigurer();
http.apply(authorizationServerConfigurer);
authorizationServerConfigurer
.authorizationEndpoint(authorizationEndpoint ->
authorizationEndpoint
.authenticationProviders(configureAuthenticationValidator())
);
return http.build();
}
private Consumer<List<AuthenticationProvider>> configureAuthenticationValidator() {
return (authenticationProviders) ->
authenticationProviders.forEach((authenticationProvider) -> {
if (authenticationProvider instanceof OAuth2AuthorizationCodeRequestAuthenticationProvider) {
Consumer<OAuth2AuthorizationCodeRequestAuthenticationContext> authenticationValidator =
// Override default redirect_uri validator
new CustomRedirectUriValidator()
// Reuse default scope validator
.andThen(OAuth2AuthorizationCodeRequestAuthenticationValidator.DEFAULT_SCOPE_VALIDATOR);
((OAuth2AuthorizationCodeRequestAuthenticationProvider) authenticationProvider)
.setAuthenticationValidator(authenticationValidator);
}
});
}
static class CustomRedirectUriValidator implements Consumer<OAuth2AuthorizationCodeRequestAuthenticationContext> {
@Override
public void accept(OAuth2AuthorizationCodeRequestAuthenticationContext authenticationContext) {
OAuth2AuthorizationCodeRequestAuthenticationToken authorizationCodeRequestAuthentication =
authenticationContext.getAuthentication();
RegisteredClient registeredClient = authenticationContext.getRegisteredClient();
String requestedRedirectUri = authorizationCodeRequestAuthentication.getRedirectUri();
// Use exact string matching when comparing client redirect URIs against pre-registered URIs
if (!registeredClient.getRedirectUris().contains(requestedRedirectUri)) {
OAuth2Error error = new OAuth2Error(OAuth2ErrorCodes.INVALID_REQUEST);
throw new OAuth2AuthorizationCodeRequestAuthenticationException(error, null);
}
}
}
