Vue项目中如何运用vuex的实战记录

// 获取用户信息
export const QUERY_USER_INFO = "QUERY_USER_INFO"

// 设置用户信息
export const SET_USER_INFO = 'SET_USER_INFO'

import { QUERY_USER_INFO } from '../action-types'
import { SET_USER_INFO, SET_CUR_MENU_ID } from '../mutation-types'
import api from '@/assets/js/api.js'

// 创建state
const state = {
    // 用户信息
    userInfo: {},
}

// 异步获取数据，commit给mutations，mutations改变state
const actions = {
    
    [QUERY_USER_INFO] ({ commit }, params) {
        return api.get({
                url: '/system/getUser',
            }, params.vm).then(data => {
                commit(SET_USER_INFO, data)
                return data
        })

    }

}

const getters = {
    // 当前用户信息
    userInfo: state => state.userInfo
}

// 同步获取
const mutations = {
    [SET_USER_INFO] (state, data) {
        state.userInfo = data
    }
}


export default {
    state,
    actions,
    getters,
    mutations
}

mport Vue from "vue"
import Vuex from "vuex"
import base from "./modules/base.js"

Vue.use(Vuex);

export default new Vuex.Store({
    modules: {
        base
    }
})

<span>{{$store.getters.userInfo.name}}</span>

import Vue from 'vue'
import store from './store'
import { QUERY_USER_INFO } from '@/store/action-types.js'

store.dispatch(QUERY_USER_INFO, {}).finally(() => {
    new Vue({
        router: router(store),
        store,
        render: h => h(App)
    }).$mount('#app')
})
