Bcrypt 的比较在 Node.Js 中不起作用

Question

I was following the tutorial from Dev.to. But I stucked on this: bcrypt's compare not working The code:

const isMatch = await bcrypt.compare(password, user.password);
  if (!isMatch){
    return res.status(400).json({
      msg: "incorrect password"
    });
  }
  

Answer 1

Is the string coming from user.password a hash?

bcrypt compares your raw string with a hash. Here's a simple working example that you can run in a node file.

const bcrypt = require('bcrypt');

const bcryptTest = async () => {
  try {
    const password = 'mypassword';
    const userPass = await bcrypt.hash('mypassword', 5);
    const isMatch = await bcrypt.compare(password, userPass);
    console.log(isMatch) // returns true
  } catch (e) {
    console.log(e)
  }
}

bcryptTest();
