如何在uni-app中使用vuex

import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
const store = new Vuex.Store({
  state: {
    hasLogin: false,
    userInfo: {}
  },
  mutations: {
    login(state, provider) {
      state.hasLogin = true;
      state.userInfo = provider;
      uni.setStorage({ //缓存用户登陆状态
        key: 'userInfo',
        data: provider
      })
    },
    logout(state) {
      state.hasLogin = false;
      state.userInfo = {};
      uni.removeStorage({
        key: 'userInfo'
      })
    }
  },
  actions: {
  }
})
export default store

import Vue from 'vue'
import App from './App'
import store from './store'
Vue.config.productionTip = false
Vue.prototype.$store = store
App.mpType = 'app'
const app = new Vue({
  store,
  ...App
})
app.$mount()

import {mapState,mapMutations} from 'vuex';

<view>{{position}}</view>//使用vuex中的值
export default {
    data() {
      return {
        address: "",
      }
    },
    computed: mapState(['position', 'userData'])
  }

methods: {
      ...mapMutations(['getPosition', 'getUserData'])
    },
//使用的话直接调用this.getPosition就可以了
