Uniapp中vueX实现登录状态功能

uniapp使用Vuex实现登录状态的判断，退出登录，使用action，commit实现登录功能

Vue.use(Vuex)

export default new Vuex.Store({
  state: {
    token: '',
    userid:'',
    username: '',
    realname: '',
    welcome: '',
    avatar: ''
  },
  mutations: {
    SET_TOKEN: (state, token) => {
      state.token = token
    },
    SET_NAME: (state, { username, realname, welcome }) => {
      state.username = username
      state.realname = realname
      state.welcome = welcome
    },
    SET_AVATAR: (state, avatar) => {
      state.avatar = avatar
    }
  },
  actions: {
    // 登录
    mLogin({ commit }, userInfo) {
      return new Promise((resolve, reject) => {
       api.login(userInfo).then(response => {
          if(response.data.code ==200){ 
            const result = response.data.result
            const userInfo = result.userInfo
			uni.setStorageSync(ACCESS_TOKEN,result.token);
			uni.setStorageSync(USER_INFO,userInfo);
            commit('SET_TOKEN', result.token)
            commit('SET_AVATAR', userInfo.avatar)
            commit('SET_NAME', { username: userInfo.username,realname: userInfo.realname})
            resolve(response)
          }else{
            resolve(response)
          }
        }).catch(error => {
			console.log("catch===>response",response)
          reject(error)
        })
      })
    },
    //手机号登录
    PhoneLogin({ commit }, userInfo) {
      return new Promise((resolve, reject) => {
        api.phoneNoLogin(userInfo).then(response => {
          if(response.data.code ==200){
            const result = response.data.result
            const userInfo = result.userInfo
			uni.setStorageSync(ACCESS_TOKEN,result.token);
			uni.setStorageSync(USER_INFO,userInfo);
            commit('SET_TOKEN', result.token)
            commit('SET_NAME', { username: userInfo.username,realname: userInfo.realname})
            commit('SET_AVATAR', userInfo.avatar)
            resolve(response)
          }else{
            reject(response)
          }
        }).catch(error => {
          reject(error)
        })
      })
    },
    // 登出
    Logout({ commit, state }) {
      return new Promise((resolve) => {
        let logoutToken = state.token;
        commit('SET_TOKEN', '')
        uni.removeStorageSync(ACCESS_TOKEN)
        api.logout(logoutToken).then(() => {
          resolve()
        }).catch(() => {
          resolve()
        })
      })
    },

  },
