dva状态管理

由model来处理逻辑，route传递fun引用给component使用

 effects: {
    *pageChangeHandler({ payload: { page } }, { put, select }) {
    // dispatch({ type: 'storeresult/fetch', payload: { page } });
    // 需要走路由，直接走方法浏览器看不出地址变化
      const keyword = yield select(state => state.storeresult.keyword);
      yield put(routerRedux.push({
        pathname: '/gitsearch/store/result',
        query: { keyword, page },
      }));
    },

// 接受路由参数
function StoreResult({ dispatch, storeresult }) {
  // 检索
  const filterHandler = (title, filterkey) => filterkey === '' || title.indexOf(filterkey) >= 0;
  // 翻页
  // const pageChangeHandler = page => dispatch({
  //   type: 'storeresult/pageChangeHandler',
  //   payload: { page },
  // });
  const pageChangeHandler = (page) => {
    dispatch({
      type: 'storeresult/pageChangeHandler',
      payload: { page },
    });
  };
  return (
    <div className={styles.normal}>
      <StoreResultComponent
        filterHandler={filterHandler}
        pageChangeHandler={pageChangeHandler}
        repos={storeresult}
      />
    </div>
