未处理的承诺拒绝警告。 Passport.js

Question

没有 catch 块的异步函数，或者拒绝未使用 .catch() 处理的承诺， 在此代码行中

async(req,email,password,done)=>{

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

    if (!user) {
        return done(null, false)
        //Err, no email found
    }

    if (!user.comparePassword(password)) {
        return done(null, false);
        // Err, pass wrong
    }

    return done(null, user);
    // Login succesfull xd
}

Answer 1

我猜你想做的是...

async function login (email,password) {

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

      if (!user || !user.comparePassword(password)) {
        throw new Error('no user or wrong pass');
      }

      return user;
      // Login succesfull xd

    } catch (error) {
       // errors including any error thrown by await User.findOne 
       return null;
    }
}
