java - 为什么 Rest API 删除调用会收到 400 状态代码

Question

我正在尝试使用mockito模拟Rest API调用。我多次尝试执行以下测试用例，但都失败并显示以下状态代码:400

我已经检查了 URI，传递的 URI 也很好，但我想知道我缺少哪里。

@RequestMapping(value = "/todo/{id}", method = RequestMethod.DELETE)
public ResponseEntity<Response> removeToDoById(@PathVariable("id") long id, @RequestParam((value = "reason") String reason) ) throws ToDoException{
    logger.info("ToDo id to remove " + id);
    ToDo toDo = toDoService.getToDoById(id);
    if (toDo == null || toDo.getId() <= 0){
        throw new ToDoException("ToDo to delete doesn´t exist");
    }
    toDoService.removeToDo(toDo);
    return new ResponseEntity<Response>(new Response(HttpStatus.OK.value(), "ToDo has been deleted"), HttpStatus.OK);
}

下面是测试调用

@Test
public void verifyDeleteToDo() throws Exception {
    mockMvc.perform(MockMvcRequestBuilders.delete("/todo/4").accept(MediaType.APPLICATION_JSON))
    .andExpect(jsonPath("$.status").value(200))
    .andExpect(jsonPath("$.message").value("ToDo has been deleted"))
    .andDo(print());
}

您的方法需要额外的参数reason，但您没有在测试方法中向 mockMvc 请求时提供该参数。

@RequestMapping(value = "/todo/{id}", method = RequestMethod.DELETE)
public ResponseEntity<Response> removeToDoById(@PathVariable("id") long id, @RequestParam((value = "reason") String reason) ) throws ToDoException{

要么把它交给mockMvc

mockMvc.perform(delete("/todo/4")
                .param("reason", "bla-bla")
                // omitted

或将其标记为“不需要”

@RequestParam(required = false, value = "reason") String reason
