如何通过登录时使用bcrypt哈希的密码检查登录密码？
我正在尝试创建一个注册/登录页面。我正在使用Nodejs，pug，猫鼬，bcrypt。哈希后，我将密码从注册或注册页面存储到数据库中。我无法使用
const user= new login.findone({email: req.body.email})
if(user){
bcryptpare(myPlaintextPassword, hash, function(err, result) {
// result == true
});
}
因为这给了我错误的结果。我也相信findOne（{email：req.body.email}）无法正常工作，或者那里也存在一些错误。
这里是处理这些验证的索引页

您能详细说明您在此处输入的哈希值吗？如果到这里一切都正确了，那么下面的代码将为您正常工作。
const user= new login.findone({email: req.body.email})
if(user){
console.log(user.password) // Check to see if password from database is returned as expected or not
bcryptpare(myPlaintextPassword, user.passsword, function(err, result) {
// Your codes
});
}
