密码错误时请求被卡住（Async/Await）

Question

So,i am quite new to async await.But i thought i should implement it in one of project to see how it really works and understands totally.But i am stuck & not able to understand what really is happening.

So in my PERN app, i am trying to log a user, so the request comes from the front end, with username and password, and then i use the findOne(sequelize), method to find if the user exist or not, and also doing the same for the password, but comparing it using bcrypt compare function.

But when the user enters a wrong email or password the whole response is stuck somehow,as i am getting a response of 500, though i have handled the error for these kind of events.

I am saying it is stuck because i added a console at the bottom of that findOne and compare function, they are not logging, but as soon as the email or password is correct the response is received.

 const { email, password } = req.body;

  console.log({ email, password });

  const user = await User.findOne({ where: { email } });

  const passwordMatch = await bcyptjs.compare(password, user.password);
  console.log('Cant Reach here when the fields are incorrect', password);
  console.log('Cant Reach here when the fields are incorrect', user.password);


  if (!user &&  !passwordMatch) {
    return next({
      message: 'Username or Password is incorrect.',
      statusCode: 400,
    });
  }

Answer 1

I think you have a typo (bcypt vc bcrypt):) And I think the method rejects when the fields do not match. So you should wrap the compare in a try/catch block. Or you could use the sync version

bcrypt.compareSync(password, user.password);

which will return true or false

Answer 2

your code is missing a try catch block to handle errors !

    const { email, password } = req.body;
    
      console.log({ email, password });

     try{

      const user = await User.findOne({ where: { email } });
    
      const passwordMatch = await bcyptjs.compare(password, user.password);
      console.log('Cant Reach here when the fields are incorrect', password);
      console.log('Cant Reach here when the fields are incorrect', user.password);
    
    }catch(e){
    console.log(e.message)
    console.log(e.statusCode)
}
