切换分页数据无变化

手动改这里是可以看到数据改变的
*fetch({ payload: { page = 1 } }, { call, put }) {
      const { data, headers } = yield call(usersService.fetch, { page });
      yield put({
        type: 'save',
        payload: {
          data,
          total: parseInt(headers['x-total-count'], 10),
          page: parseInt(page, 10),
        },
      });
    },
