next.js getServerSideProps 修改redux 组件没有更新

Question

page/index.js

export const getStaticProps = wrapper.getStaticProps(async ({ store }) => {
  store.dispatch(serverRenderClock(true))
  store.dispatch(addCount())
})

the reducer.js

import { countActionTypes } from './action'

const countInitialState = {
  count: 0,
}

export default function reducer(state = countInitialState, action) {
  switch (action.type) {
    case countActionTypes.ADD:
      return Object.assign({}, state, {
        count: state.count + 1,
      })
    default:
      return state
  }
}

按理说 store.dispatch(addCount())执行了这段代码发起了redux请求，那么count应该加了1，为什么页面显示还是0呢？
