node.js - Mongoose 所需的验证器失败值未定义

Question

我尝试将数据保存在 Mongoose 模式中，但所需的验证器失败，错误消息显示该值未定义，但之前的日志表明它有一个值。

我尝试使用新的 mongoose.Schema 而不是新的 Schema，但这也不起作用。

当我删除所需的标签时，它会保存，但它是空的: { 预订编号: { _id: 5d4b47d7685936130080eb70, __v: 0 } }

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const BookingNumberSchema = new Schema({
    number: {
        type: Number,
        required: true,
    },
    description: {
        type: String,
        required: true,
    },
});

const BookingNumber = mongoose.model('BookingNumber', BookingNumberSchema);

module.exports = BookingNumber;



function createBookingNumber(req, res){ 

    console.log(req.body);
    BookingNumber.create(req.body)
        .then(bookingNumber =>{
            let reply = {
                "bookingNumber": bookingNumber
            }
            res.status(200);
            console.log(reply);
            res.send(reply);
        })
        .catch(err =>{
            res.status(400);
            console.log(err);
            res.send(err);
        });
}

在我的 app.js 中，我使用 bodyParser.json 和过滤器来进行 nosql 攻击:

app.use(bodyParser.json());

app.use(filter());

postman 数据:

{
    "bookingNumber": { 
        "number": 1,
        "description": "example bookingnumber"
    }
} 

回复:

{
    "errors": {
        "description": {
            "message": "Path `description` is required.",
            "name": "ValidatorError",
            "properties": {
                "message": "Path `description` is required.",
                "type": "required",
                "path": "description"
            },
            "kind": "required",
            "path": "description"
        },
        "number": {
            "message": "Path `number` is required.",
            "name": "ValidatorError",
            "properties": {
                "message": "Path `number` is required.",
                "type": "required",
                "path": "number"
            },
            "kind": "required",
            "path": "number"
        }
    },
    "_message": "BookingNumber validation failed",
    "message": "BookingNumber validation failed: description: Path `description` is required., number: Path `number` is required.",
    "name": "ValidationError"
}

控制台日志:

{ bookingNumber: { number: 1, description: 'example bookingnumber' } }
{ ValidationError: BookingNumber validation failed: description: Path `description` is required., number: Path `number` is required.
        message: 'Path `description` is required.',
        name: 'ValidatorError',
        properties: [Object],
        kind: 'required',
        path: 'description',
        value: undefined,
        reason: undefined,
        [Symbol(mongoose:validatorError)]: true },
     number:

我看起来输入值没有传递给 Mongoose ，但我找不到原因。

在你发送数据的 postman 中:

{
   "bookingNumber": { 
       "number": 1,
       "description": "example bookingnumber"
   }
} 

并且您的架构 BookingNumber 没有像您使用嵌套对象发送“bookingNumber”那样的键， Mongoose 验证器检查没有“编号”和“描述”，这就是您的请求失败的原因。 只需发送如下:

{ 
   "number": 1,
   "description": "example bookingnumber"
}
