自定义hook之首页数据请求动作封装 hooks

本例子实现了自定义hook之首页数据请求动作封装 hooks，具体代码如下

export type OrganData = {
  dis: Array<{ disease: string; id: number }>;
  is_delete: number;
  name: string;
  organ_id: number;
  parent_id: number;
  sort: number;
};
export type SwiperData = {
  id: string;
  module1_id: string;
  module2_id: string;
  title: string;
  sort: string;
  has_app_header: string;
  url: string;
  content: string;
  litpic: string;
  posttime: string;
  status: string;
  weapp_url: string;
};
export interface ResponseType<T> {
  code: number;
  msg: string;
  data?: T;
  runtime?: number;
}
import { useEffect, useState } from 'react';
import { useToast } from 'taro-hooks';
import Apis from '../services';

export enum FetchType {
  Swiper, // 首页swiper 数据
  Nav, // 首页nav 数据
}

/**
 * 首页数据请求动作封装 hooks
 * @param type 请求类型
 * @returns
 */
const useFetchData = (type: FetchType) => {
  const [data, setData] = useState([]);
  const [showToast] = useToast();

  useEffect(() => {
    const fetchData = async () => {
      let res;
      if (type === FetchType.Swiper) {
        res = (await Apis.fetchSwiperData()) as ResponseType<SwiperData[]>;
      }
      if (type === FetchType.Nav) {
        res = (await Apis.fetchOrganData()) as ResponseType<OrganData[]>;
      }
      if (res?.code === 200) {
        setData(res?.data);
      } else {
        showToast({ title: res?.msg });
      }
    };
    fetchData();
  }, [showToast, type]);
  return [data];
};

export default useFetchData;
