我正在使用Redux和Normalizr在TypeScript中构建React Native应用程序。所以我会有一个规范化的状态。
我有四个接口：Emotion、Need、PainData和PainReport：

export interface Emotion {
  name: string;
  chosen: boolean;
  rating: number;
}

export interface Need {
  name: string;
  rating: number;
}

export interface PainData {
  note: string;
  emotions: Emotion[];
  needs: Need[];
  date: Date;
}

export interface PainReport {
  [date: string]: PainData
}

现在我想创建一个接口，它不是一个数组，而是一个允许多个PainReport的对象，如下所示（伪代码）：

export interface PseudoPainReportsObject {
  [date: string]: PainData,
  [date: string]: PainData,
  [date: string]: PainData,
  // ... dynamically have as many as I'd like. Maybe 1, maybe 100
}

我想用它来规范化状态，就像你使用Normalizr时得到的那样。
如何实现这样的类型或接口？
