<script>
import { useStore } from 'vuex'
export default {
  setup() {
    const store = useStore()
    const state = store.state
   	const methods = {
   	  // 处理commit
      handleMutation: () => {
        store.commit(...)
      },
      // 处理dispatch
      handleAction: () => {
        store.dispatch(...)
      }
