Express/Mongoose 抛出新错误未通过

Question

在使用邮递员测试我的 api 时，我在使用 mongoose 时遇到了 1 个问题。

1. userSchema 中的 throw new Error() 都不会返回 route.post catch 错误。
   
   

如何让throw new Error() 返回到router.post 脚​​本？

当电子邮件和密码与数据库中的内容匹配时，脚本可以正常工作。

如果我console.log(no email) 或no password 使用透视if() 语句，它们会触发，但throw new Error() 消息不会传递到router.post 上的catch 语句。如果我在 router.post 上 console.log(error) 我得到

错误：未找到电子邮件 在 Function.userSchema.statics.validatePassword (C:\Users\Samson\Documents\JS\nodeProjects\task-manager\src\models\users.js:60:15) 在 processTicksAndRejections (internal/process/task_queues.js:97:5) 在异步 C:\Users\Samson\Documents\JS\nodeProjects\task-manager\src\routers\user.js:66:22

但是传回邮递员的是{}

下面我将提供用户模型、模式和路由的代码和屏幕截图。post

Schema Object

    userSchema.statics.validatePassword = async function (email, password) {
    const user = this;
    const userObj = await user.findOne({
        "email": email
    });

    if (!userObj) {
        console.log("no email")
        throw new Error("No email found ");
    }

    const answer = await bcrypt.compare(password, userObj.password);

    if (!answer) {
        console.log("no password")
        throw new Error('Incorrect Password');
    }

    return answer;

}

猫鼬用户模型

    const userSchema = new mongoose.Schema({
    name: {
        type: String,
        required: true,
        trim: true,
        lowercase: true,
        validate(name) {
            if (name.length <= 0) {
                throw new Error("Please fill in a name");
            }
        }

    },
    age: {
        type: Number,
        required: true,
        validate(age) {
            if (age < 18) {
                throw new Error('Participates must be 18 years of age or older');
            }
        }
    },
    email: {
        type: String,
        required: true,
        lowercase: true,
        trim: true,
        unique: true,
        validate(address) {
            if (!validator.isEmail(address)) {
                throw new Error('Please enter a valid email address');
            }
        }
    },
    password: {
        type: String,
        required: true,
        trim: true,
        validate(secret) {
            if (secret.length <= 6 || secret.includes('password')) {
                throw new Error("Please select a password longer than 6 characters and that doesn't include the term password");
            }
        }
    }
});

router.post

    router.post('/users/login', async (req, res) => {

    try {
        const user = await User.validatePassword(req.body.email, req.body.password);
        res.status(200).send("user and password validated " + user);
    } catch (error) {
        console.log(error)
        res.status(400).send(error);
    }
});

Answer 1

userSchema.statics.validatePassword = async function (email, password) {
const user = this;
const userObj = await user.findOne({
    "email": email
});

if (!userObj) {
    return 0
}

const answer = await bcrypt.compare(password, userObj.password);

if (!answer) {
    return -1;
}

return answer;
}

router.post

router.post('/users/login', async (req, res) => {

try {
    const user = await User.validatePassword(req.body.email, req.body.password);
if(user == 0){
    return res.status(404).send('no email found')
}
if(user == -1){
    return res.status(404).send('Incorrect Password')
}
    res.status(200).send("user and password validated " + user);
} catch (error) {
    console.log(error)
    res.status(400).send(error);
}
});
