= Authorization Grant Support
|

|
||
[[oauth2Client-auth-code-grant]]
|
||
== Authorization Code
|
||
|
||
[NOTE]
|
||
Please refer to the OAuth 2.0 Authorization Framework for further details on the https://tools.ietf.org/html/rfc6749#section-1.3.1[Authorization Code] grant.
|
||
|
||
|
||
=== Obtaining Authorization
|
||
|
||
[NOTE]
|
||
Please refer to the https://tools.ietf.org/html/rfc6749#section-4.1.1[Authorization Request/Response] protocol flow for the Authorization Code grant.
|
||
|
||
|
||
=== Initiating the Authorization Request
|
||
|
||
The `OAuth2AuthorizationRequestRedirectWebFilter` uses a `ServerOAuth2AuthorizationRequestResolver` to resolve an `OAuth2AuthorizationRequest` and initiate the Authorization Code grant flow by redirecting the end-user's user-agent to the Authorization Server's Authorization Endpoint.
|
||
|
||
The primary role of the `ServerOAuth2AuthorizationRequestResolver` is to resolve an `OAuth2AuthorizationRequest` from the provided web request.
|
||
The default implementation `DefaultServerOAuth2AuthorizationRequestResolver` matches on the (default) path `+/oauth2/authorization/{registrationId}+` extracting the `registrationId` and using it to build the `OAuth2AuthorizationRequest` for the associated `ClientRegistration`.
|
||
|
||
Given the following Spring Boot 2.x properties for an OAuth 2.0 Client registration:
|
||
|
||
[source,yaml,attrs="-attributes"]
|
||
----
|
||
spring:
|
||
security:
|
||
oauth2:
|
||
client:
|
||
registration:
|
||
okta:
|
||
client-id: okta-client-id
|
||
client-secret: okta-client-secret
|
||
authorization-grant-type: authorization_code
|
||
redirect-uri: "{baseUrl}/authorized/okta"
|
||
scope: read, write
|
||
provider:
|
||
okta:
|
||
authorization-uri: https://dev-1234.oktapreview.com/oauth2/v1/authorize
|
||
token-uri: https://dev-1234.oktapreview.com/oauth2/v1/token
|
||
----
|
||
|
||
A request with the base path `/oauth2/authorization/okta` will initiate the Authorization Request redirect by the `OAuth2AuthorizationRequestRedirectWebFilter` and ultimately start the Authorization Code grant flow.
|
||
|
||
[NOTE]
|
||
The `AuthorizationCodeReactiveOAuth2AuthorizedClientProvider` is an implementation of `ReactiveOAuth2AuthorizedClientProvider` for the Authorization Code grant,
|
||
which also initiates the Authorization Request redirect by the `OAuth2AuthorizationRequestRedirectWebFilter`.
|
||
|
||
If the OAuth 2.0 Client is a https://tools.ietf.org/html/rfc6749#section-2.1[Public Client], then configure the OAuth 2.0 Client registration as follows:
|
||
|
||
[source,yaml,attrs="-attributes"]
|
||
----
|
||
spring:
|
||
security:
|
||
oauth2:
|
||
client:
|
||
registration:
|
||
okta:
|
||
client-id: okta-client-id
|
||
client-authentication-method: none
|
||
authorization-grant-type: authorization_code
|
||
redirect-uri: "{baseUrl}/authorized/okta"
|
||
...
|
||
----
|
||
|
||
Public Clients are supported using https://tools.ietf.org/html/rfc7636[Proof Key for Code Exchange] (PKCE).
|
||
If the client is running in an untrusted environment (eg. native application or web browser-based application) and therefore incapable of maintaining the confidentiality of it's credentials, PKCE will automatically be used when the following conditions are true:
|
||
|
||
. `client-secret` is omitted (or empty)
|
||
. `client-authentication-method` is set to "none" (`ClientAuthenticationMethod.NONE`)
|
||
|
||
[TIP]
|
||
If the OAuth 2.0 Provider supports PKCE for https://tools.ietf.org/html/rfc6749#section-2.1[Confidential Clients], you may (optionally) configure it using `DefaultServerOAuth2AuthorizationRequestResolver.setAuthorizationRequestCustomizer(OAuth2AuthorizationRequestCustomizers.withPkce())`.
|
||
|
||
[[oauth2Client-auth-code-redirect-uri]]
|
||
The `DefaultServerOAuth2AuthorizationRequestResolver` also supports `URI` template variables for the `redirect-uri` using `UriComponentsBuilder`.
|
||
|
||
The following configuration uses all the supported `URI` template variables:
|
||
|
||
[source,yaml,attrs="-attributes"]
|
||
----
|
||
spring:
|
||
security:
|
||
oauth2:
|
||
client:
|
||
registration:
|
||
okta:
|
||
...
|
||
redirect-uri: "{baseScheme}://{baseHost}{basePort}{basePath}/authorized/{registrationId}"
|
||
...
|
||
----
|
||
|
||
[NOTE]
|
||
`+{baseUrl}+` resolves to `+{baseScheme}://{baseHost}{basePort}{basePath}+`
|
||
|
||
Configuring the `redirect-uri` with `URI` template variables is especially useful when the OAuth 2.0 Client is running behind a xref:features/exploits/http.adoc#http-proxy-server[Proxy Server].
|
||
This ensures that the `X-Forwarded-*` headers are used when expanding the `redirect-uri`.
|
||
|
||
=== Customizing the Authorization Request
|
||
|
||
One of the primary use cases a `ServerOAuth2AuthorizationRequestResolver` can realize is the ability to customize the Authorization Request with additional parameters above the standard parameters defined in the OAuth 2.0 Authorization Framework.
|
||
|
||
For example, OpenID Connect defines additional OAuth 2.0 request parameters for the https://openid.net/specs/openid-connect-core-1_0.html#AuthRequest[Authorization Code Flow] extending from the standard parameters defined in the https://tools.ietf.org/html/rfc6749#section-4.1.1[OAuth 2.0 Authorization Framework].
|
||
One of those extended parameters is the `prompt` parameter.
|
||
|
||
[NOTE]
|
||
OPTIONAL. Space delimited, case sensitive list of ASCII string values that specifies whether the Authorization Server prompts the End-User for reauthentication and consent. The defined values are: none, login, consent, select_account
|
||
|
||
The following example shows how to configure the `DefaultServerOAuth2AuthorizationRequestResolver` with a `Consumer<OAuth2AuthorizationRequest.Builder>` that customizes the Authorization Request for `oauth2Login()`, by including the request parameter `prompt=consent`.

.additionalParameters { params -> params["prompt"] = "consent" }
|
||
}
|
||
}
|
||
}
|
||
----
|
||
======
|
||
|
||
For the simple use case, where the additional request parameter is always the same for a specific provider, it may be added directly in the `authorization-uri` property.
|
||
|
||
For example, if the value for the request parameter `prompt` is always `consent` for the provider `okta`, than simply configure as follows:
|
||
|
||
[source,yaml]
|
||
----
|
||
spring:
|
||
security:
|
||
oauth2:

client:
|
||
provider:
|
||
okta:
|
||
authorization-uri: https://dev-1234.oktapreview.com/oauth2/v1/authorize?prompt=consent
|
||
----
|
||
|
||
The preceding example shows the common use case of adding a custom parameter on top of the standard parameters.
|
||
Alternatively, if your requirements are more advanced, you can take full control in building the Authorization Request URI by simply overriding the `OAuth2AuthorizationRequest.authorizationRequestUri` property.
|
||
|
||
[TIP]
|
||
`OAuth2AuthorizationRequest.Builder.build()` constructs the `OAuth2AuthorizationRequest.authorizationRequestUri`, which represents the Authorization Request URI including all query parameters using the `application/x-www-form-urlencoded` format.
|
||
|
||
The following example shows a variation of `authorizationRequestCustomizer()` from the preceding example, and instead overrides the `OAuth2AuthorizationRequest.authorizationRequestUri` property.

=== Storing the Authorization Request
|
||
|
||
The `ServerAuthorizationRequestRepository` is responsible for the persistence of the `OAuth2AuthorizationRequest` from the time the Authorization Request is initiated to the time the Authorization Response is received (the callback).
|
||
|
||
[TIP]
|
||
The `OAuth2AuthorizationRequest` is used to correlate and validate the Authorization Response.
|
||
|
||
The default implementation of `ServerAuthorizationRequestRepository` is `WebSessionOAuth2ServerAuthorizationRequestRepository`, which stores the `OAuth2AuthorizationRequest` in the `WebSession`.
|
||
|
||
If you have a custom implementation of `ServerAuthorizationRequestRepository`, you may configure it as shown in the following example:

||
|
||

=== Requesting an Access Token
|
||
|
||
[NOTE]
|
||
Please refer to the https://tools.ietf.org/html/rfc6749#section-4.1.3[Access Token Request/Response] protocol flow for the Authorization Code grant.
|
||
|
||
The default implementation of `ReactiveOAuth2AccessTokenResponseClient` for the Authorization Code grant is `WebClientReactiveAuthorizationCodeTokenResponseClient`, which uses a `WebClient` for exchanging an authorization code for an access token at the Authorization Server’s Token Endpoint.
|
||
|
||
The `WebClientReactiveAuthorizationCodeTokenResponseClient` is quite flexible as it allows you to customize the pre-processing of the Token Request and/or post-handling of the Token Response.
|
||
|
||
|
||
=== Customizing the Access Token Request
|
||
|
||
If you need to customize the pre-processing of the Token Request, you can provide `WebClientReactiveAuthorizationCodeTokenResponseClient.setParametersConverter()` with a custom `Converter<OAuth2AuthorizationCodeGrantRequest, MultiValueMap<String, String>>`.
|
||
The default implementation builds a `MultiValueMap<String, String>` containing only the `grant_type` parameter of a standard https://tools.ietf.org/html/rfc6749#section-4.1.3[OAuth 2.0 Access Token Request] which is used to construct the request. Other parameters required by the Authorization Code grant are added directly to the body of the request by the `WebClientReactiveAuthorizationCodeTokenResponseClient`.
|
||
However, providing a custom `Converter`, would allow you to extend the standard Token Request and add custom parameter(s).
|
||
|
||
[TIP]
|
||
If you prefer to only add additional parameters, you can instead provide `WebClientReactiveAuthorizationCodeTokenResponseClient.addParametersConverter()` with a custom `Converter<OAuth2AuthorizationCodeGrantRequest, MultiValueMap<String, String>>` which constructs an aggregate `Converter`.
|
||
|
||
IMPORTANT: The custom `Converter` must return valid parameters of an OAuth 2.0 Access Token Request that is understood by the intended OAuth 2.0 Provider.
|
||
|
||
|
||
=== Customizing the Access Token Response
|
||
|
||
On the other end, if you need to customize the post-handling of the Token Response, you will need to provide `WebClientReactiveAuthorizationCodeTokenResponseClient.setBodyExtractor()` with a custom configured `BodyExtractor<Mono<OAuth2AccessTokenResponse>, ReactiveHttpInputMessage>` that is used for converting the OAuth 2.0 Access Token Response to an `OAuth2AccessTokenResponse`.
|
||
The default implementation provided by `OAuth2BodyExtractors.oauth2AccessTokenResponse()` parses the response and handles errors accordingly.
|
||
|
||
=== Customizing the `WebClient`
|
||
|
||
Alternatively, if your requirements are more advanced, you can take full control of the request/response by simply providing `WebClientReactiveAuthorizationCodeTokenResponseClient.setWebClient()` with a custom configured `WebClient`.
|
||
|
||
Whether you customize `WebClientReactiveAuthorizationCodeTokenResponseClient` or provide your own implementation of `ReactiveOAuth2AccessTokenResponseClient`, you’ll need to configure it as shown in the following example:

=== Refreshing an Access Token
|
||
|

[NOTE]
|
||
Please refer to the https://tools.ietf.org/html/rfc6749#section-6[Access Token Request/Response] protocol flow for the Refresh Token grant.
|
||
|
||
The default implementation of `ReactiveOAuth2AccessTokenResponseClient` for the Refresh Token grant is `WebClientReactiveRefreshTokenTokenResponseClient`, which uses a `WebClient` when refreshing an access token at the Authorization Server’s Token Endpoint.
|
||
|
||
The `WebClientReactiveRefreshTokenTokenResponseClient` is quite flexible as it allows you to customize the pre-processing of the Token Request and/or post-handling of the Token Response.

However, providing a custom `Converter`, would allow you to extend the standard Token Request and add custom parameter(s).
|
||
|

If you prefer to only add additional parameters, you can instead provide `WebClientReactiveRefreshTokenTokenResponseClient.addParametersConverter()` with a custom `Converter<OAuth2RefreshTokenGrantRequest, MultiValueMap<String, String>>` which constructs an aggregate `Converter`.
|

IMPORTANT: The custom `Converter` must return valid parameters of an OAuth 2.0 Access Token Request that is understood by the intended OAuth 2.0 Provider.
|
||

On the other end, if you need to customize the post-handling of the Token Response, you will need to provide `WebClientReactiveRefreshTokenTokenResponseClient.setBodyExtractor()` with a custom configured `BodyExtractor<Mono<OAuth2AccessTokenResponse>, ReactiveHttpInputMessage>` that is used for converting the OAuth 2.0 Access Token Response to an `OAuth2AccessTokenResponse`.

||
The default implementation provided by `OAuth2BodyExtractors.oauth2AccessTokenResponse()` parses the response and handles errors accordingly.

=== Customizing the `WebClient`
|

||
Alternatively, if your requirements are more advanced, you can take full control of the request/response by simply providing `WebClientReactiveRefreshTokenTokenResponseClient.setWebClient()` with a custom configured `WebClient`.
|
||
|

Whether you customize `WebClientReactiveRefreshTokenTokenResponseClient` or provide your own implementation of `ReactiveOAuth2AccessTokenResponseClient`, you’ll need to configure it as shown in the following example:

The default implementation of `ReactiveOAuth2AccessTokenResponseClient` for the Client Credentials grant is `WebClientReactiveClientCredentialsTokenResponseClient`, which uses a `WebClient` when requesting an access token at the Authorization Server’s Token Endpoint.
|
||
|
||
The `WebClientReactiveClientCredentialsTokenResponseClient` is quite flexible as it allows you to customize the pre-processing of the Token Request and/or post-handling of the Token Response.
|
||
|
||
|
||
=== Customizing the Access Token Request
|
||
|
||
If you need to customize the pre-processing of the Token Request, you can provide `WebClientReactiveClientCredentialsTokenResponseClient.setParametersConverter()` with a custom `Converter<OAuth2ClientCredentialsGrantRequest, MultiValueMap<String, String>>`.
|
||
The default implementation builds a `MultiValueMap<String, String>` containing only the `grant_type` parameter of a standard https://tools.ietf.org/html/rfc6749#section-4.4.2[OAuth 2.0 Access Token Request] which is used to construct the request. Other parameters required by the Client Credentials grant are added directly to the body of the request by the `WebClientReactiveClientCredentialsTokenResponseClient`.
|
||
However, providing a custom `Converter`, would allow you to extend the standard Token Request and add custom parameter(s).
|
||
|
||
[TIP]
|
||
If you prefer to only add additional parameters, you can instead provide `WebClientReactiveClientCredentialsTokenResponseClient.addParametersConverter()` with a custom `Converter<OAuth2ClientCredentialsGrantRequest, MultiValueMap<String, String>>` which constructs an aggregate `Converter`.
|
||
|
||
IMPORTANT: The custom `Converter` must return valid parameters of an OAuth 2.0 Access Token Request that is understood by the intended OAuth 2.0 Provider.
|
||
|
||
|
||
=== Customizing the Access Token Response
|
||
|
||
On the other end, if you need to customize the post-handling of the Token Response, you will need to provide `WebClientReactiveClientCredentialsTokenResponseClient.setBodyExtractor()` with a custom configured `BodyExtractor<Mono<OAuth2AccessTokenResponse>, ReactiveHttpInputMessage>` that is used for converting the OAuth 2.0 Access Token Response to an `OAuth2AccessTokenResponse`.
|
||
The default implementation provided by `OAuth2BodyExtractors.oauth2AccessTokenResponse()` parses the response and handles errors accordingly.
|
||
|
||
=== Customizing the `WebClient`
|
||
|
||
Alternatively, if your requirements are more advanced, you can take full control of the request/response by simply providing `WebClientReactiveClientCredentialsTokenResponseClient.setWebClient()` with a custom configured `WebClient`.
|
||
|
||
Whether you customize `WebClientReactiveClientCredentialsTokenResponseClient` or provide your own implementation of `ReactiveOAuth2AccessTokenResponseClient`, you'll need to configure it as shown in the following example:

[NOTE]
|
||
`JwtBearerReactiveOAuth2AuthorizedClientProvider` resolves the `Jwt` assertion via `OAuth2AuthorizationContext.getPrincipal().getPrincipal()` by default, hence the use of `JwtAuthenticationToken` in the preceding example.
|
||
|
||
[TIP]
|
||
If you need to resolve the `Jwt` assertion from a different source, you can provide `JwtBearerReactiveOAuth2AuthorizedClientProvider.setJwtAssertionResolver()` with a custom `Function<OAuth2AuthorizationContext, Mono<Jwt>>`.
