/signup与/login路由异常：VS Code报错但Postman请求成功

• 开发/api/v1/users/signup和/api/v1/users/login路由时，VS Code持续弹出提示：Error: Can't find /api/v1/users/signup on the server :( !，/login路由出现完全相同的提示
• 但使用Postman发送POST请求到这两个接口时，返回状态均为success，接口功能完全符合预期

相关代码片段 #

app.js #

app.use("/api/v1/users", userRouter);

usersRoute.js #

router.post("/signup", authController.signup);
router.post("/login", authController.login);

控制器方法头部定义 #

exports.signup = catchAsync(async (request, response, next) => {}
exports.login = catchAsync(async (request, response, next) => {}

错误排查用代码（含日志打印） #

const catchAsync = (asyncFunction) => {  
  console.log("INSIDE CATCHASYNC 1");
  
  return (request, response, next) => {
    console.log("INSIDE CATCHASYNC 2");
    asyncFunction(request, response, next).catch((error) => {
      console.log(error);
      console.log(error.stack);
      
      console.log("INSIDE CATCHASYNC 3");
      next(error);
    });
  };
};

exports.login = catchAsync(async (request, response, next) => {
  console.log("++++++1+++++++");
  
  const { email, password } = request.body;

  // 1- 检查邮箱和密码是否提供
  if (!email || !password)
    return next(new AppError(400, "请提供邮箱和密码以登录！"));

  // 2- 检查用户是否存在，验证密码是否匹配
  const user = await User.findOne({ email }) 
    .select("+password"); 

  // 3- 验证通过则生成并返回token
  if (!user || !(await user.comparePassword(password, user.password)))
    return next(new AppError(401, "邮箱或密码错误！"));
  
  console.log("++++++2+++++++");
  const token = signature(user._id);
  console.log("++++++12+++++++");
  response.status(200).json({
    status: "success",
    token
  });
  console.log("above next() in login");

  next();
});
