Question

我目前正在使用TypeScript和MongoDB使用Express开发RESTful API。我选择的ORM是猫鼬。使用以下POST请求测试我的应用程序时：

curl -i -X POST -H "Content-Type: application/json" -d '{ "first_name":"hansi"}' localhost:3000

我收到以下错误消息，指出属性“ first_name”是必需的：

        message: 'Enter a first name',
        name: 'ValidatorError',
        properties: [Object],
        kind: 'required',
        path: 'first_name',
        value: undefined,
        reason: undefined,
        [Symbol(mongoose:validatorError)]: true } },
  _message: 'Person validation failed',
  name: 'ValidationError' }

但是，当我注释掉'“ required：”输入一个字符串“”时，不会引发服务器错误。但是我在架构中使用的first_name和所有其他字符串属性仍然没有添加到集合中。

集合中只有Mongo生成的“ ids”和birth_date（current_timestamp）的默认值。

我的架构（personSchema.ts）：

//imports

const Schema = mongoose.Schema;

export const PersonSchema = new Schema({
    first_name: {
        type: String
        //required: "Enter a first name"
    },
    ...
    birth_date: {
        type: Date,
        default: Date.now
    } 
}, { collection: 'person' });

路由器（personRouter.ts）：

//imports

export class PersonRoute {
    public personController: PersonController = new PersonController();

    public routes(app): void {
      ...
      //getrequests
      ...

      app.route("/").post((req: Request, res: Response) => {

        const PersonModel = mongoose.model('Person', PersonSchema);

        PersonModel.create(req.body, function (err, post) {
          if (err) console.log(err);
          res.json(post);
        });
      });
    }
}

我的测试请求是否可能有问题？

编辑：我在Postman中测试了发帖请求，仍然得到了相同的结果：

猫鼬会忽略发布请求中的字符串属性
