1.store-》module-》config文件内容

2.store->index.ts文件内容

import Vue from 'vue'
import Vuex, { StoreOptions } from 'vuex'
import createPersistedState from 'vuex-persistedstate'

import config, { ConfigState } from './modules/config'
// import category, { CategoryState } from './modules/category'
// import prebill, { PrebillState } from './modules/prebill'
import platform from '@/utils/platform'

Vue.use(Vuex)

interface RootState {
  config: ConfigState
 // category: CategoryState
 // prebill: PrebillState
}


const store: StoreOptions<RootState> = {
  modules: {
    config,
    // category,
   // prebill
  },
  plugins: [
    createPersistedState({
      storage: platform.isWechat
        ? window.sessionStorage : window.localStorage
    })
  ]
}

export default new Vuex.Store<RootState>(store)

3.页面组件用到store数据时如下：

import { namespace } from 'vuex-class'
const Config = namespace('config')
export default class Index extends Vue {
  @Config.State('user') user
  @Config.Mutation('方法名')  方法名
  @Config.Actions('方法名')  方法名
}
