使用外部身份验证源时如何在Spring Boot中模拟身份验证

Question

我有一个基于Spring Boot的应用程序，我们使用来自外部提供商的ISAM身份验证。我有一个rest / json端点/actuator/health，它根据用户是否通过身份验证返回不同的数据。

如何在单元测试期间模拟身份验证以确保配置正确？

在setup()中，我尝试手动设置令牌，并覆盖AuthorizationService以返回true。

@Before
public void setUp() throws Exception
{
   mockMvc = webAppContextSetup(wac).apply(springSecurity()).build();

   List roles = Arrays.asList(new SimpleGrantedAuthority("ROLE_USER"));

   UsernamePasswordAuthenticationToken auth =
           new UsernamePasswordAuthenticationToken("dave", "secret",
                                                   roles);

   if (!auth.isAuthenticated()) { fail("NOT AUTHENTICATED!"); }

   SecurityContextHolder.getContext().setAuthentication(auth);

   //fake logged in
   when(authorizationService.isCurrentUserAuthorized(anyString(),
                                                     anyString(),
                                                     ArgumentMatchers.any(ResourceType.class),
                                                     ArgumentMatchers.any(ActionType.class)))
     .thenReturn(true);
}

但是，当我跑步时

Authentication auth = SecurityContextHolder.getContext().getAuthentication();

if (!auth.isAuthenticated()) { fail("NOT AUTHENTICATED!"); }

UsernamePasswordAuthenticationToken authToken =
              (UsernamePasswordAuthenticationToken)auth;

mockMvc.perform(get("/health_secure")
                  .principal(auth)
                  .header("Authorization", "Bearer " + token))
       .andDo(print())
       .andExpect(status().isOk())
       .andExpect(forwardedUrl("/actuator/health"));

我得到：

"error":"invalid_token","error_description":"Cannot convert access token to JSON"

Answer 1

答案正确here。由于Spring Security不会创建请求范围的bean，因此请自己创建一个bean并将其注入到需要的地方。这使您有机会自己模拟它。

这样的事情？：

@Service
@RequiredArgsConstructor
public class UserService {

    public Principal getPrincipal() {
        return SecurityContextHolder.getContext().getAuthentication();
    }

    public Optional<String> getCurrentLogin() {
        Principal principal = getPrincipal();
        if (principal == null)
            return Optional.empty();
        return Optional.ofNullable(principal.getName());
    }

}

Answer 2

我的应用程序通过ISAM / OAuth2]进行身份验证

我希望只是覆盖AuthenticationManager或OAuth2AuthenticationManager

我找到了一个较低级别的解决方案。

NOTE：

我很想在AuthenticationManager级别查看解决方案。

我必须重写ResourceServerTokenServices bean来模拟我的假Auth数据。

我在setAuth()方法中添加了@Before方法。

   //"constants" for fake auth values
   private static final String user = "MyUser";
   private static final String token = "MyTokenString";

   //TokenServices to validate/convert ISAM Bearer Token
   @MockBean ResourceServerTokenServices tokenServices;

   private Authentication setAuth() throws Exception
   {
      UsernamePasswordAuthenticationToken auth =
              new UsernamePasswordAuthenticationToken(user, token,
                                                      Collections.emptyList());

      if (!auth.isAuthenticated()) { fail("NOT AUTHENTICATED!"); }

      SecurityContextHolder.getContext().setAuthentication(auth);

      DefaultOAuth2AccessToken mockTokenImpl = new DefaultOAuth2AccessToken(user);
      mockTokenImpl.setScope(Collections.singleton("authenticate:applications"));
      mockTokenImpl.setTokenType("Bearer");

      when(tokenServices.readAccessToken(anyString())).thenReturn(mockTokenImpl);

      OAuth2Authentication oa2Auth = mock(OAuth2Authentication.class);
      when(oa2Auth.getPrincipal()).thenReturn(user);
      when(oa2Auth.getCredentials()).thenReturn(token);
      when(oa2Auth.getUserAuthentication()).thenReturn(auth);
      when(oa2Auth.isAuthenticated()).thenReturn(true);

      OAuth2Request oa2Req = mock(OAuth2Request.class);
      when(oa2Auth.getOAuth2Request()).thenReturn(oa2Req);

      when(tokenServices.loadAuthentication(anyString())).thenReturn(oa2Auth);

      return auth;
   }
此方法将tokenServices配置为具有使用Springs authenticate()类通过OAuth2AuthenticationManager伪造它的所有必要信息。
