node.js - bcrypt.compare JWT 与 nodeJS，Mongoose 总是抛出错误

Question

当我尝试在 NodeJS 中实现 JWT，Mongoose 作为我的身份验证机制时，我遇到了这个有点傻的问题。

假设我尝试使用此代码（NodeJS）实现登录功能

const post_login = async (req, res, next) => {
    const userData = req.body;

    try {
        const user = await User.login(userData);
        res.status(200).json({user: user._id});
    } catch (error) {
        res.status(400).json({});
    }
    // res.json(userData)
};

然后我在我的模型数据中附加这个函数

UserSchema.statics.login = async function(userData){
    const {email, password} = userData;
    const user = await this.findOne({email});
    
    if (user) {
        const auth = await bcrypt.compare(password, user.password)
        if (auth) {
            return user;
        }
        throw Error('Password do not match');
    } 
    throw Error('Email is not registered');
};

我在 mongoDB 中存储数据时成功实现了 bcrypt.hash。但是，当我尝试这些代码时，它总是抛出一个错误（状态 4000）。在我做了一些调试之后，问题是

1. 当我调试await bcrypt.compare(password, user.password)时，我发现它看起来像是在未散列的“密码”与存储的（散列的）密码“user.password”之间进行比较
2. 如果我跳过bcrypt.compare，它会返回相关的文档数据（即使提供的密码不匹配）
3. 显示错误消息

4. 我在 nodeV14 上运行

介意任何人知道如何解决它，提前谢谢
