NodeJS：Bcrypt：错误：非法参数：未定义，字符串

Question

这是我用来对登录应用程序进行验证的控制器代码的一部分，因此所有内容都已正确插入数据库及其加密权限中，但是当我尝试提交用户数据时，它无法验证密码，说错误位于 bcrypt.compare，我输入了正确的错误，即使我输入错误，它也应该将我重定向到主页，而不是程序崩溃。

AuthController.js：

exports.PostLogin = (req, res, next) => {

    const password = req.body.password
    const email = req.body.email

    User.findOne({ where: {email : email}})
    .then((user) => {
        if (!user) {
           flash.req("errors","Ha ocurrido un error al momento de ingresar el Correo electronico")
    return res.redirect("/login")
    }

    bcrypt
    .compare(password, user.password)
    .then((result) =>{
        if (result){
            req.session.IsloggedIn=true
            req.session.user = user
            return req.session.save((err) =>
            {
                flash.req("errors","Contreseña invalida")

                console.log("Error al momento de compare",err)
                res.redirect("/")
            });
        }
        res.redirect("/login")

    });

正如 @epascarello 提到的，您将遍历用户集合并尝试根据您输入的电子邮件获取用户，该电子邮件应使用异步 - 等待调用进行包装。这样它就会等待用户被发现，然后将密码与

bcrypt

进行比较

exports.PostLogin = async (req, res, next) => {

    const password = req.body.password
    const email = req.body.email

    await User.findOne({ where: {email : email}})
    .then((user) => {
    bcrypt
    .compare(password, user.password)
    .then((result) =>{
        if (result){
            req.session.IsloggedIn=true
            req.session.user = user
            return req.session.save((err) =>
            {
                flash.req("errors","Contreseña invalida")

                console.log("Error al momento de compare",err)
                res.redirect("/")
            });
        }
        res.redirect("/login")

    });
