步骤流程

1.找到user.js

2.在user.js中找到以下几个地方

属性：state{}属性：mutations{}函数：GetInfo()

3.在user.js中添加代码 

4.在自己的页面中添加获取id的代码

步骤一

在该若依的版本中，从下列目录找到，ruoyi-ui->src->store->modules->user.js

 步骤二

属性state在页面中的位置

state: { token: getToken(), name: '', avatar: '', roles: [], permissions: [] },

还有mutations

mutations: { SET_TOKEN: (state, token) => { state.token = token }, SET_NAME: (state, name) => { state.name = name }, SET_AVATAR: (state, avatar) => { state.avatar = avatar }, SET_ROLES: (state, roles) => { state.roles = roles }, SET_PERMISSIONS: (state, permissions) => { state.permissions = permissions }}

最后是GetInfo方法

GetInfo({ commit, state }) { return new Promise((resolve, reject) => { getInfo().then(res => { const user = res.user const avatar = (user.avatar == "" || user.avatar == null) ? require("@/assets/images/profile.jpg") : process.env.VUE_APP_BASE_API + user.avatar; if (res.roles && res.roles.length > 0) { // 验证返回的roles是否是一个非空数组 commit('SET_ROLES', res.roles) commit('SET_PERMISSIONS', res.permissions) } else { commit('SET_ROLES', ['ROLE_DEFAULT']) } commit('SET_NAME', user.userName) commit('SET_AVATAR', avatar) resolve(res) }).catch(error => { reject(error) }) }) },

步骤三

到此处开始添加代码

user.js中，state

添加id属性

state: { token: getToken(), name: '', id:'',//添加的用户id avatar: '', roles: [], permissions: [] },

mutations中添加SET_ID

mutations: {//添加方法 SET_ID: (state, userId) => { state.id = userId }, SET_TOKEN: (state, token) => { state.token = token }, SET_NAME: (state, name) => { state.name = name }, SET_AVATAR: (state, avatar) => { state.avatar = avatar }, SET_ROLES: (state, roles) => { state.roles = roles }, SET_PERMISSIONS: (state, permissions) => { state.permissions = permissions }

最后在GetInfo中添加，设置缓存id的代码

commit('SET_ID', user.userId)

// 获取用户信息 GetInfo({ commit, state }) { return new Promise((resolve, reject) => { getInfo().then(res => { const user = res.user const avatar = (user.avatar == "" || user.avatar == null) ? require("@/assets/images/profile.jpg") : process.env.VUE_APP_BASE_API + user.avatar; if (res.roles && res.roles.length > 0) { // 验证返回的roles是否是一个非空数组 commit('SET_ROLES', res.roles) commit('SET_PERMISSIONS', res.permissions) } else { commit('SET_ROLES', ['ROLE_DEFAULT']) } commit('SET_ID', user.userId)//添加这行代码 commit('SET_NAME', user.userName) commit('SET_AVATAR', avatar) resolve(res) }).catch(error => { reject(error) }) }) },

步骤三

在自己的页面中使用缓存中的用户id

首先导入包import store from "@/store";写在<script>标签中

<script>import store from "@/store";export default { data(){ return{ userId:store.state.user.id//将缓存的用户id赋值给userId } }}。。。。。</script>
