如何在打字稿中动态设置对象键

Question

如何创建一个函数，其中对象的键是从函数动态设置的

export const validateObjectId = (key: string = 'id'): ObjectSchema => {
  return Joi.object({
    key: Joi.string()
      .regex(/^(?=[a-f\d]{24}$)(\d+[a-f]|[a-f]+\d)/i)
      .required(),
  });
};

如何让key成为对象的key

Answer 1

也许您可以尝试以下方法：

export const validateObjectId = (key: string = 'id'): ObjectSchema => {
    let object: any = {};
    object[key] = Joi.string()
          .regex(/^(?=[a-f\d]{24}$)(\d+[a-f]|[a-f]+\d)/i)
          .required();
    return Joi.object(object);
}

干杯

Answer 2

我已经能够使用下面的代码片段找到出路

export const validateObjectId = (key: string = 'id'): ObjectSchema => {
  interface Obj {
    [key: string]: Object;
  }

  const object: Obj = {};

  object[key] = Joi.string()
    .regex(/^(?=[a-f\d]{24}$)(\d+[a-f]|[a-f]+\d)/i)
    .required();
  return Joi.object(object);
};
