Java 使用MockMvc获取httpServletRequest属性

我有一个非常简单的控制器，定义如下：

@RequestMapping(value = "/api/test", method = RequestMethod.GET, produces = "application/json")
public @ResponseBody Object getObject(HttpServletRequest req, HttpServletResponse res) {
    Object userId = req.getAttribute("userId");
    if (userId == null){
        res.setStatus(HttpStatus.BAD_REQUEST.value());
    }
    [....]
}

我试图以多种不同的方式使用MockMvc调用，但是，我无法提供属性“userId”

例如，在这种情况下，它不起作用：

MockHttpSession mockHttpSession = new MockHttpSession(); 
mockHttpSession.setAttribute("userId", "TESTUSER");             
mockMvc.perform(get("/api/test").session(mockHttpSession)).andExpect(status().is(200)).andReturn(); 

我也尝试过，但没有成功：

MvcResult result = mockMvc.perform(get("/api/test").with(new RequestPostProcessor() {
     public MockHttpServletRequest postProcessRequest(MockHttpServletRequest request) {
           request.setParameter("userId", "testUserId");
           request.setRemoteUser("TESTUSER");
           return request;
     }
})).andExpect(status().is(200)).andReturn(); 

在这种情况下，我可以设置RemoteUser，但不能在HttpServletRequest上设置属性映射

有什么线索吗？

您可以通过调用

requestAttr

^^

mockMvc.perform(get("/api/test").requestAttr("userId", "testUserId")...

//试验方法

@Mock
private HttpServletRequest httpServletRequest
@Mock
private MerchantCredentialsChangeService mockCredentionChangeService;

@Test
public void testValidateEmailToken() throws Exception {
    final String token = "akfkldakkadjfiafkakflkd";
    final String expectedUsername = "9841414141";

    Mockito.when(mockCredentionChangeService.getUserByToken(Matchers.eq(token), Matchers.any(HttpServletRequest.class)))
            .thenReturn(expectedUsername);

    mockMvc.perform(get(Routes.VALIDATE_EMAIL_TOKEN + "/validate")
            .param("token", token))
            .andExpect(status().isOk())
            .andExpect(MockMvcResultMatchers.content().string(expectedUsername));
}

你可以用

mvc.perform(post("/api/v1/...")
    .with(request -> {
      request.addHeader(HEADER_USERNAME_KEY, approver);
      request.setAttribute("attrName", "attrValue");
      return request;
    })
    .contentType(MediaType.APPLICATION_JSON)...

参数！=这救了我一天。从早上开始我就在浪费时间。非常感谢。

mvc.perform(post("/api/v1/...")
    .with(request -> {
      request.addHeader(HEADER_USERNAME_KEY, approver);
      request.setAttribute("attrName", "attrValue");
      return request;
    })
    .contentType(MediaType.APPLICATION_JSON)...
