spring - 使用mockmvc和junit添加csrf token

Question

我有一个包含两个元的 View (我正在使用 thymeleaf):

    <meta name="_csrf" th:content="${_csrf.token}" />
    <meta name="_csrf_header" th:content="${_csrf.headerName}" />

在我的测试 Controller 中我这样做:

HttpSessionCsrfTokenRepository httpSessionCsrfTokenRepository = new HttpSessionCsrfTokenRepository();
CsrfToken csrfToken2 = httpSessionCsrfTokenRepository.generateToken(new MockHttpServletRequest());

CustomUser user = new CustomUser();
user.setName("foo");
user.setSurname("fooo");
List<GrantedAuthority> grantedAuthorities = new ArrayList<GrantedAuthority>();
grantedAuthorities.add(new SimpleGrantedAuthority("role"));

UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken("foo", "fooo", grantedAuthorities);
token.setDetails(user);     

MockHttpSession session = new MockHttpSession();
session.setAttribute(HttpSessionSecurityContextRepository.SPRING_SECURITY_CONTEXT_KEY, new MockSecurityContext(token));
session.setAttribute("_csrf", csrfToken2);


this.mockMvc.perform(post("/foo/update")
            .param("param", "asdfasd")
            ....
            .session(session)
            )
        .andExpect(view().name(("foo/detail"))).andExpect(model().hasErrors())  

当我运行测试时，出现此错误(未找到 token 或为空):

我找到了一个临时解决方案，但它不是一个好的解决方案..:

<th:block th:if="${_csrf}">
   <meta name="_csrf" th:content="${_csrf.token}" />
   <meta name="_csrf_header" th:content="${_csrf.headerName}" />
</th:block> 

Answer 1

要访问您需要的 session 属性

th:text="${session._csrf.headerName}">
th:text="${session._csrf.token}">

参见spring thymeleaf

如果您在测试中使用 MockMvc，您可以使用

设置 csrf token

mvc
.perform(post("/").with(csrf()))

参见web security
