Spring Security 提供了与 Okta 集成的支持,可以使用预定义的类从 Okta 获取访问令牌。
要从 Okta 获取访问令牌,需要进行以下步骤:
@Bean
public OAuth2AuthorizedClientManager authorizedClientManager(
ClientRegistrationRepository clientRegistrationRepository,
OAuth2AuthorizedClientRepository authorizedClientRepository) {
OAuth2AuthorizedClientProvider authorizedClientProvider =
OAuth2AuthorizedClientProviderBuilder.builder()
.clientCredentials()
.build();
DefaultOAuth2AuthorizedClientManager authorizedClientManager =
new DefaultOAuth2AuthorizedClientManager(
clientRegistrationRepository, authorizedClientRepository);
authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);
return authorizedClientManager;
}
@Configuration
public class OktaOAuth2ClientConfig {
private final OAuth2AuthorizedClientManager authorizedClientManager;
public OktaOAuth2ClientConfig(OAuth2AuthorizedClientManager authorizedClientManager) {
this.authorizedClientManager = authorizedClientManager;
}
@Bean
public ClientRegistrationRepository clientRegistrationRepository() {
return new InMemoryClientRegistrationRepository(oktaClientRegistration());
}
@Bean
public OAuth2AuthorizedClientRepository authorizedClientRepository() {
return new HttpSessionOAuth2AuthorizedClientRepository();
}
@Bean
public OAuth2AuthorizedClientService authorizedClientService() {
return new InMemoryOAuth2AuthorizedClientService(
clientRegistrationRepository());
}
@Bean
public OAuth2AuthorizedClientProvider authorizedClientProvider() {
return OAuth2AuthorizedClientProviderBuilder.builder()
.clientCredentials()
.build();
}
@Bean
public WebClient webClient(OAuth2AuthorizedClientRepository authorizedClientRepository) {
ServletOAuth2AuthorizedClientExchangeFilterFunction oauth2 =
new ServletOAuth2AuthorizedClientExchangeFilterFunction(
authorizedClientManager);
oauth2.setDefaultClientRegistrationId("okta");
return WebClient.builder()
.apply(oauth2.oauth2Configuration())
.build();
}
private ClientRegistration oktaClientRegistration() {
return ClientRegistration.withRegistrationId("okta")
.clientId("your-client-id")
.clientSecret("your-client-secret")
.authorizationGrantType(AuthorizationGrantType.CLIENT_CREDENTIALS)
.tokenUri("https://your-okta-domain.com/oauth2/default/v1/token")
.scope("your-scope")
.build();
}
}
注意:请将上述代码中的 "your-client-id"、"your-client-secret"、"your-okta-domain.com" 和 "your-scope" 替换为实际的 Okta 应用程序属性。
OAuth2RestTemplate
从 Okta 获取访问令牌。@Autowired
private OAuth2RestTemplate restTemplate;
public String getAccessTokenFromOkta() {
OAuth2AccessTokenResponse accessTokenResponse =
restTemplate.getAccessToken();
// 获取访问令牌
OAuth2AccessToken accessToken = accessTokenResponse.getAccessToken();
return accessToken.getTokenValue();
}
以上代码中的 OAuth2RestTemplate
是通过自动装配注入的。在使用此代码时,请确保已配置 OAuth2RestTemplate
Bean。
这样,您就可以使用 Spring 预定义的类从 Okta 获取访问令牌了。
