ts 递归的将一个对象上的所有方法改成返回promise

type Promiseify<T> = T extends Promise<infer P> ? T : Promise<T>;
type apisPromise<P> = {
  readonly [K in keyof P]: P[K] extends (...args: any) => any
    ? (...arg: Parameters<P[K]>) => Promiseify<ReturnType<P[K]>>
    : P[K] extends Object
    ? apisPromise<P[K]>
    : P[K];
};
