错误：找不到/api/v1/users/signup，但Postman显示了路线数据

我在 /signup 和 /login 路线中遇到奇怪的错误

Vscode 不断向我显示“错误：在服务器上找不到 /api/v1/users/signup :(！”

另一方面，Postman 的状态为“成功”，一切运行正常且符合预期。

/login 也会发生同样的事情

以下是相关代码：

app.js：

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

usersRoute.js：

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

注册和登录的标题：

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

我收到错误的代码片段在这里： 注意：我添加了 console.log 来确定错误发生的位置，我发现它是在从 Postman 发出 POST 请求后发生的，在我的控制台中打印的第一件事是

console.log("INSIDE CATCHASYNC 2");

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- checking email and pawword :
  if (!email || !password)
    return next(new AppError(400, "Please provide your email and password to login !"));

  // 2- checking if the user is exists and the entered data match with db data or not :
  const user = await User.findOne({ email }) // we're using findOne not ById because in the situation we're not selecting a user by its id but with user's email .
    .select("+password"); 

  // 3- okay? send the token to the user:
  if (!user || !(await userparePassword(password, user.password)))
    return next(new AppError(401, "Incorrect email or password !"));
  
    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();
});

这是控制台的屏幕截图：

在这段代码中

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

  // 1- checking email and pawword :
  if (!email || !password)
    return next(new AppError(400, "Please provide your email and password to login !"));

  // 2- checking if the user is exists and the entered data match with db data or not :
  const user = await User.findOne({ email }) // we're using findOne not ById because in the situation we're not selecting a user by its id but with user's email .
    .select("+password"); 

  // 3- okay? send the token to the user:
  if (!user || !(await userparePassword(password, user.password)))
    return next(new AppError(401, "Incorrect email or password !"));
  
    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();
});

您不应该在最后

next()

response.status(200).json({
    status: "success",
    token
  });

所以你不希望有下一个中间件，无论如何，即使你想执行另一个中间件，你也应该将

request

response

next(request,response,next)
