如何让 @WebMvcTest 与 OAuth 一起使用?

I tried to use @WithMockUser, @WithUserDetails and even define my own annotation with @WithSecurityContext and a custom UserSecurityContextFactory but always got anonymous user in the UserSecurityContext when security expression where evaluated, whatever I set the test context to in my factory...

我提出了我刚刚提出的解决方案，但由于我不确定模拟 TokenService 是最有效/最干净的方法，请随时提供更好的解决方案.

I propose the solution I came to just under, but as I'm not sure mocking the TokenService is the most efficient / clean way to go, please feel free to provide better.

以下解决方案特定于 spring-security-oauth2，现已弃用.
我写了 一个 lib 来实现与 Spring5 相同的目标，其中一些是对 spring-安全测试 5.2.他们选择仅集成 JWT 流 API，因此如果您需要测试服务(需要使用注释)或使用不透明令牌自省，您可能需要稍微浏览一下我的 repo...

The Solution below is specific to spring-security-oauth2 which is now deprecated.
I wrote a lib to achieve the same goal with Spring5, some of which is contributed to spring-security-test 5.2. They chose to integrate the JWT flow API only, so if you need to test a service (requires the use of an annotation) or use opaque tokens introspection, you might need to browse my repo a bit...

我现在发布我的spring-addons".Spring 5 的库到 maven-central，其中大大提高可用性.
源代码和自述文件仍在 github 上.

I now publish my "spring-addons" libs for Spring 5 to maven-central, which greatly improve usability.
Source and READMEs still on github.

[spring-security-oauth2 的解决方案]
我迭代的解决方案是结合一个虚拟的授权".请求中的标头带有拦截它的模拟令牌服务(如果您查看编辑堆栈，经过多次尝试).

[solution for spring-security-oauth2]
The solution I iterated to is combining a dummy "Authorization" header in requests with a mocked token service intercepting it (after quite a few tries if you look at edits stack).

我在 Github 上的 lib 你可以找到示例 OAuth2 控制器测试 那里.

I provide with complete helpers source in a lib on Github and you can find sample OAuth2 controller test there.

简而言之:没有授权标头->ResourceServerTokenServices 未触发 ->SecurityContext 在 OAuth 堆栈中将是匿名的(无论您尝试使用 @WithMockUser 或类似方法将其设置为什么).

To make it short: no Authorization header -> ResourceServerTokenServices is not triggered -> SecurityContext will be anonymous in OAuth stack (whatever you try to set it to with @WithMockUser or alike).

这里有两种情况:

• 您正在编写集成测试，提供有效令牌并让真正的令牌服务完成工作并提供包含在此令牌中的身份验证
• 您正在编写单元测试、我的案例和模拟令牌服务，以便它返回模拟身份验证

一种类似的方法，我在拉了几天头发并从头开始构建它后了解到，已经描述了这里.我只是在 @WebMvcTests 的模拟 Oauth2Authentication 配置和工具中走得更远.

A similar approach, I understood after pulling my hair for a few days and building this from ground up, has already been described here. I just went further in mocked Oauth2Authentication configuration and tooling for @WebMvcTests.

使用示例

由于这篇文章很长，公开了一个涉及相当多代码的解决方案，让我们从结果开始，以便您决定是否值得阅读；)

As this post is long, exposing a solution involving quite some code, lets get started with the result so that you can decide if it's worth reading ;)

@WebMvcTest(MyController.class) // Controller to unit-test
@Import(WebSecurityConfig.class) // your class extending WebSecurityConfigurerAdapter
public class MyControllerTest extends OAuth2ControllerTest {

    @Test
    public void testWithUnauthenticatedClient() throws Exception {
        api.post(payload, "/endpoint")
                .andExpect(...);
    }

    @Test
    @WithMockOAuth2Client
    public void testWithDefaultClient() throws Exception {
        api.get("/endpoint")
                .andExpect(...);
    }

    @Test
    @WithMockOAuth2User
    public void testWithDefaultClientOnBehalfDefaultUser() throws Exception {
            MockHttpServletRequestBuilder req = api.postRequestBuilder(null, "/uaa/refresh")
                .header("refresh_token", JWT_REFRESH_TOKEN);

        api.perform(req)
                .andExpect(status().isOk())
                .andExpect(...)
    }

    @Test
    @WithMockOAuth2User(
        client = @WithMockOAuth2Client(
                clientId = "custom-client",
                scope = {"custom-scope", "other-scope"},
                authorities = {"custom-authority", "ROLE_CUSTOM_CLIENT"}),
        user = @WithMockUser(
                username = "custom-username",
                authorities = {"custom-user-authority"}))
    public void testWithCustomClientOnBehalfCustomUser() throws Exception {
        api.get(MediaType.APPLICATION_ATOM_XML, "/endpoint")
                .andExpect(status().isOk())
                .andExpect(xpath(...));
    }
}

时髦，不是吗?

附:api 是 MockMvcHelper 的一个实例，它是我自己的 MockMvc 包装器，在本文末尾提供.

P.S. api is an instance of MockMvcHelper, a wrapper of my own for MockMvc, provided at the end of this post.

@WithMockOAuth2Client 模拟仅客户端身份验证(不涉及最终用户)

@WithMockOAuth2Client to simulate client only authentication (no end-user involved)

@Retention(RetentionPolicy.RUNTIME)
@WithSecurityContext(factory = WithMockOAuth2Client.WithMockOAuth2ClientSecurityContextFactory.class)
public @interface WithMockOAuth2Client {

    String clientId() default "web-client";

    String[] scope() default {"openid"};

    String[] authorities() default {};

    boolean approved() default true;

    class WithMockOAuth2ClientSecurityContextFactory implements WithSecurityContextFactory<WithMockOAuth2Client> {

        public static OAuth2Request getOAuth2Request(final WithMockOAuth2Client annotation) {
            final Set<? extends GrantedAuthority> authorities = Stream.of(annotation.authorities())
                    .map(auth -> new SimpleGrantedAuthority(auth))

@WithMockOAuth2User 代表最终用户模拟客户端身份验证

@WithMockOAuth2User to simulate client authenticating on behalf of an end-user

@Retention(RetentionPolicy.RUNTIME)

         * @return an Authentication with provided user details
         */
        public static UsernamePasswordAuthenticationToken getUserAuthentication(final WithMockUser user) {
            final String principal = user.username().isEmpty() ? user.value() : user.username();

            final Stream<String> grants = user.authorities().length == 0 ?
                    Stream.of(user.roles()).map(r -> "ROLE_" + r) :
                    Stream.of(user.authorities());

            final Set<? extends GrantedAuthority> userAuthorities = grants
                    .map(auth -> new SimpleGrantedAuthority(auth))
                    .collect(Collectors.toSet());

            return new UsernamePasswordAuthenticationToken(
                    new User(principal, user.password(), userAuthorities),
                    principal + ":" + user.password(),
                    userAuthorities);
        }

        @Override
        public SecurityContext createSecurityContext(final WithMockOAuth2User annotation) {
            final SecurityContext ctx = SecurityContextHolder.createEmptyContext();
            ctx.setAuthentication(new OAuth2Authentication(

OAuth2MockMvcHelper 帮助构建带有预期授权标头的测试请求

OAuth2MockMvcHelper helps build test requests with expected Authorization header

public class OAuth2MockMvcHelper extends MockMvcHelper {
    public static final String VALID_TEST_TOKEN_VALUE = "test.fake.jwt";

    public OAuth2MockMvcHelper(
            final MockMvc mockMvc,
            final ObjectFactory<HttpMessageConverters> messageConverters,
            final MediaType defaultMediaType) {
        super(mockMvc, messageConverters, defaultMediaType);
    }

    /**
     * Adds OAuth2 support: adds an Authorisation header to all request builders
     * if there is an OAuth2Authentication in test security context.
     * 
     * /! Make sure your token services recognize this dummy "VALID_TEST_TOKEN_VALUE" token as valid during your tests /!
     *
     * @param contentType should be not-null when issuing request with body (POST, PUT, PATCH), null otherwise
     * @param accept      should be not-null when issuing response with body (GET, POST, OPTION), null otherwise
     * @param method
     * @param urlTemplate
     * @param uriVars
     * @return a request builder with minimal info you can tweak further (add headers, cookies, etc.)
     */
    @Override
    public MockHttpServletRequestBuilder requestBuilder(
            Optional<MediaType> contentType,
            Optional<MediaType> accept,
            HttpMethod method,
            String urlTemplate,
            Object... uriVars) {
        final MockHttpServletRequestBuilder builder = super.requestBuilder(contentType, accept, method, urlTemplate, uriVars);
        if (SecurityContextHolder.getContext().getAuthentication() instanceof OAuth2Authentication) {
            builder.header("Authorization", "Bearer " + VALID_TEST_TOKEN_VALUE);
        }
        return builder;
    }
}

OAuth2ControllerTest 控制器单元测试的父级

OAuth2ControllerTest a parent for controllers unit-tests

@RunWith(SpringRunner.class)
@Import(OAuth2MockMvcConfig.class)
public class OAuth2ControllerTest {

    @MockBean
    private ResourceServerTokenServices tokenService;

    @Autowired
    protected OAuth2MockMvcHelper api;

    @Autowired
    protected SerializationHelper conv;

    @Before
    public void setUpTokenService() {
        when(tokenService.loadAuthentication(api.VALID_TEST_TOKEN_VALUE))
                .thenAnswer(invocation -> SecurityContextHolder.getContext().getAuthentication());
    }
}

@TestConfiguration
class OAuth2MockMvcConfig {

    @Bean
    public SerializationHelper serializationHelper(ObjectFactory<HttpMessageConverters> messageConverters) {
        return new SerializationHelper(messageConverters);
    }

    @Bean
    public OAuth2MockMvcHelper mockMvcHelper(
            MockMvc mockMvc,
            ObjectFactory<HttpMessageConverters> messageConverters,
            @Value("${controllers.default-media-type:application/json;charset=UTF-8}") MediaType defaultMediaType) {
        return new OAuth2MockMvcHelper(mockMvc, messageConverters, defaultMediaType);
    }

}

上面提到但与 OAuth2 测试没有直接关系的工具

/**
 * Wraps MockMvc to further ease interaction with tested API:
 * provides with:<ul>
 * <li>many request shortcuts for simple cases (see get, post, put, patch, delete methods)</li>
 * <li>perfom method along with request builder initialisation shortcuts (see getRequestBuilder, etc.) when more control is required (additional headers, ...)</li>
 * </ul>

    private final MediaType defaultMediaType;

        this.mockMvc = mockMvc;
        this.conv = new SerializationHelper(messageConverters);
        this.defaultMediaType = defaultMediaType;
