需求

ruoyi-app原生自带只有avatar、name、roles、permissions；在显示中，我们大多数需要nick_name、user_id；当然获取方式也可以通过name去调用接口查询，但我想偷个懒。

代码

代码已经调好的，复制即用；至于修改点，细心一点应该能自己发现

1、修改 store/modules/user.js 文件

import config from '@/config'
import storage from '@/utils/storage'
import constant from '@/utils/constant'
import { login, logout, getInfo } from '@/api/login'
import { getToken, setToken, removeToken } from '@/utils/auth'

const baseUrl = config.baseUrl

const user = {
  state: {
    token: getToken(),
    name: storage.get(constant.name),
    userId: storage.get(constant.userId),
    nickName: storage.get(constant.nickName),
    avatar: storage.get(constant.avatar),
    roles: storage.get(constant.roles),
    permissions: storage.get(constant.permissions)
  },

  mutations: {
    SET_TOKEN: (state, token) => {
      state.token = token
    },
    SET_NAME: (state, name) => {
      state.name = name
      storage.set(constant.name, name)
    },
	SET_USER_ID: (state, userId) => {
	  state.userId = userId
	  storage.set(constant.userId, userId)
	},
	SET_NICK_NAME: (state, nickName) => {
	  state.nickName = nickName
	  storage.set(constant.nickName, nickName)
	},
    SET_AVATAR: (state, avatar) => {
      state.avatar = avatar
      storage.set(constant.avatar, avatar)
    },
    SET_ROLES: (state, roles) => {
      state.roles = roles
      storage.set(constant.roles, roles)
    },
    SET_PERMISSIONS: (state, permissions) => {
      state.permissions = permissions
      storage.set(constant.permissions, permissions)
    }
  },

  actions: {
    // 登录
    Login({ commit }, userInfo) {
      const username = userInfo.username.trim()
      const password = userInfo.password
      const code = userInfo.code
      const uuid = userInfo.uuid
      return new Promise((resolve, reject) => {
        login(username, password, code, uuid).then(res => {
          setToken(res.token)
          commit('SET_TOKEN', res.token)
          resolve()
        }).catch(error => {
          reject(error)
        })
      })
    },

    // 获取用户信息
    GetInfo({ commit, state }) {
      return new Promise((resolve, reject) => {
        getInfo().then(res => {
          const user = res.user
          const avatar = (user == null || user.avatar == "" || user.avatar == null) ? require("@/static/images/profile.jpg") : baseUrl + user.avatar
          const username = (user == null || user.userName == "" || user.userName == null) ? "" : user.userName
          const userId = (user == null || user.userId == "" || user.userId == null) ? "" : user.userId
		  const nickName = (user == null || user.nickName == "" || user.nickName == null) ? "" : user.nickName
          if (res.roles && res.roles.length > 0) {
            commit('SET_ROLES', res.roles)
            commit('SET_PERMISSIONS', res.permissions)
          } else {
            commit('SET_ROLES', ['ROLE_DEFAULT'])
          }
          commit('SET_NAME', username)
          commit('SET_USER_ID', userId)
          commit('SET_NICK_NAME', nickName)
          commit('SET_AVATAR', avatar)
          resolve(res)
        }).catch(error => {
          reject(error)
        })
      })
    },

    // 退出系统
    LogOut({ commit, state }) {
      return new Promise((resolve, reject) => {
        logout(state.token).then(() => {
          commit('SET_TOKEN', '')
          commit('SET_ROLES', [])
          commit('SET_PERMISSIONS', [])
          removeToken()
          storage.clean()
          resolve()
        }).catch(error => {
          reject(error)
        })
      })
    }
  }
}

export default user

2、修改 store/getter.js 文件

const getters = {
  token: state => state.user.token,
  avatar: state => state.user.avatar,
  name: state => state.user.name,
  userId: state => state.user.userId,
  nickName: state => state.user.nickName,
  roles: state => state.user.roles,
  permissions: state => state.user.permissions
}
export default getters

3、修改 utils/storage.js 文件

import constant from './constant'

// 存储变量名
let storageKey = 'storage_data'

// 存储节点变量名
let storageNodeKeys = [constant.avatar, constant.name,constant.userId,constant.nickName, constant.roles, constant.permissions]

const storage = {
  set: function(key, value) {
    if (storageNodeKeys.indexOf(key) != -1) {
      let tmp = uni.getStorageSync(storageKey)
      tmp = tmp ? tmp : {}
      tmp[key] = value
      uni.setStorageSync(storageKey, tmp)
    }
  },
  get: function(key) {
    let storageData = uni.getStorageSync(storageKey) || {}
    return storageData[key] || ""
  },
  remove: function(key) {
    let storageData = uni.getStorageSync(storageKey) || {}
    delete storageData[key]
    uni.setStorageSync(storageKey, storageData)
  },
  clean: function() {
    uni.removeStorageSync(storageKey)
  }
}

export default storage

4、修改 utils/constant.js 文件

const constant = {
   avatar: 'vuex_avatar',
   name: 'vuex_name',
   userId: 'vuex_user_id',
   nickName: 'vuex_nick_name',
   roles: 'vuex_roles',
   permissions: 'vuex_permissions'
 }

 export default constant
