spring - 模拟 Keycloak token 以测试 Spring Controller

Question

我想为我的 spring Controller 编写单元测试。我正在使用 keycloak 的 openid 流程来保护我的端点。

在我的测试中，我使用了 @WithMockUser用于模拟经过身份验证的用户的注释。我的问题是我正在从主体的 token 中读取 userId。我的单元测试现在失败了，因为 userId我从 token 中读取为空；

        if (principal instanceof KeycloakAuthenticationToken) {
            KeycloakAuthenticationToken authenticationToken = (KeycloakAuthenticationToken) principal;
            SimpleKeycloakAccount account = (SimpleKeycloakAccount) authenticationToken.getDetails();
            RefreshableKeycloakSecurityContext keycloakSecurityContext = account.getKeycloakSecurityContext();
            AccessToken token = keycloakSecurityContext.getToken();
            Map<String, Object> otherClaims = token.getOtherClaims();
            userId = otherClaims.get("userId").toString();
        }

有什么可以轻松模拟 KeycloakAuthenticationToken ?

Answer 1

@WithmockUser 使用 UsernamePasswordAuthenticationToken 配置安全上下文。这对于大多数用例来说都很好，但是当您的应用程序依赖另一个身份验证实现时(就像您的代码一样)，您必须构建或模拟正确类型的实例并将其放入测试安全上下文中:SecurityContextHolder.getContext().setAuthentication(authentication);当然，你很快就会想要自动化这个，构建你自己的注释或 RequestPostProcessor... 或者 ...
拿一个“现成的”，就像这个 lib of mine ，它可以从 maven-central 获得:

<dependency>
    <groupId>com.c4-soft.springaddons</groupId>
    <artifactId>spring-security-oauth2-test-webmvc-addons</artifactId>
    <version>2.3.4</version>
    <scope>test</scope>
</dependency>

您可以将它与 @WithMockKeycloackAuth 注释一起使用:

@RunWith(SpringRunner.class)
@WebMvcTest(GreetingController.class)
@ContextConfiguration(classes = GreetingApp.class)
@ComponentScan(basePackageClasses = { KeycloakSecurityComponents.class, KeycloakSpringBootConfigResolver.class })
public class GreetingControllerTests extends ServletUnitTestingSupport {
    @MockBean
    MessageService messageService;

    @Test
    @WithMockKeycloackAuth("TESTER")
    public void whenUserIsNotGrantedWithAuthorizedPersonelThenSecretRouteIsNotAccessible() throws Exception {
        mockMvc().get("/secured-route").andExpect(status().isForbidden());
    }

    @Test
    @WithMockKeycloackAuth("AUTHORIZED_PERSONNEL")
    public void whenUserIsGrantedWithAuthorizedPersonelThenSecretRouteIsAccessible() throws Exception {
        mockMvc().get("/secured-route").andExpect(content().string(is("secret route")));
    }

    @Test
    @WithMockKeycloakAuth(
            authorities = { "USER", "AUTHORIZED_PERSONNEL" },
            id = @IdTokenClaims(sub = "42"),
            oidc = @OidcStandardClaims(
                    email = "ch4mp@c4-soft.com",
                    emailVerified = true,
                    nickName = "Tonton-Pirate",
                    preferredUsername = "ch4mpy"),
            privateClaims = @ClaimSet(stringClaims = @StringClaim(name = "foo", value = "bar")))
    public void whenAuthenticatedWithKeycloakAuthenticationTokenThenCanGreet() throws Exception {
        mockMvc().get("/greet")
                .andExpect(status().isOk())
                .andExpect(content().string(startsWith("Hello ch4mpy! You are granted with ")))
                .andExpect(content().string(containsString("AUTHORIZED_PERSONNEL")))
                .andExpect(content().string(containsString("USER")));
    }

或者 MockMvc fluent API(RequestPostProcessor):

@RunWith(SpringRunner.class)
@WebMvcTest(GreetingController.class)
@ContextConfiguration(classes = GreetingApp.class)
@ComponentScan(basePackageClasses = { KeycloakSecurityComponents.class, KeycloakSpringBootConfigResolver.class })
public class GreetingControllerTest extends ServletKeycloakAuthUnitTestingSupport {
    @MockBean
    MessageService messageService;

    @Test
    public void whenUserIsNotGrantedWithAuthorizedPersonelThenSecretMethodIsNotAccessible() throws Exception {
        mockMvc().with(authentication().roles("TESTER")).get("/secured-method").andExpect(status().isForbidden());
    }

    @Test
    public void whenUserIsGrantedWithAuthorizedPersonelThenSecretMethodIsAccessible() throws Exception {
        mockMvc().with(authentication().roles("AUTHORIZED_PERSONNEL")).get("/secured-method")
                .andExpect(content().string(is("secret method")));
    }

}
