如何在 typescript 中動態設置 object 密鑰

Question

如何創建 function，其中 object 的密鑰是從 function 動態設置的

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(),
  });
};

如何使鑰匙成為 object 的鑰匙

Answer 1

也許您可以嘗試以下方法：

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

我已經能夠使用下面的代碼片段找到出路

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);
};
