在我的数据库中成功注册数据后，护照身份验证在node.js中显示未经授权？

Question

我已经使用类的注册函数创建了一个带有 docSchema 注册的注册路由。 现在的问题是，在前端注册时，它不会抛出任何错误，而是将数据注册到我的数据库中，但不会重定向到登录路由。相反，它会抛出未经授权的 401 错误，并且我的登录路线在使用正确的详细信息登录后显示相同的错误。奇怪的是，确切的代码之前可以正常运行，没有任何问题。请帮我解决这个问题。

Answer 1

const userSchema = new mongoose.Schema({
    username: String,
    password: String,
    name: String,
    age: String,
    qualifications: String,
    exp: String
});

userSchema.plugin(passportLocalMongoose);

const User = mongoose.model("User", userSchema);
passport.use(User.createStrategy());

passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());
------------
app.post('/register', function (req, res) {
    const newUser = new User({
        username: req.body.username,
        name: req.body.name,
        age: req.body.age,
        qualifications: req.body.qualifications,
        exp: req.body.exp
    });

    User.register(newUser, req.body.password, function (err) {
        if (err) {
            console.log(err);
            res.redirect("/register");
        } else {
            passport.authenticate("local")(req, res, function () {
                res.redirect("/login");
            });
        }
    });
});
 combine both
