Vue 3+Vite+Eectron从入门到实战系列之(五)一后台管理登录页

前面已经讲了不少基础知识，这篇开始，我们进行实操，做个后台管理系统，打包成多端的,可安装的桌面app!!其中，登录，退出的提示信息用系统的提示，不使用elementplus的弹窗提示！！

实现效果

核心代码实现

pinia的配置

js 复制代码

import { createPinia } from "pinia";
const pinia = createPinia();

export default pinia;

登录退出功能的store

js 复制代码

import { defineStore } from 'pinia'
const userStore = defineStore('user', {
  state: () => ({
    userInfo: {
      name: 'admin',
      avatar: '',
      roles: ['admin'],
      introduction: 'I am a super administrator'
    },
    token: window.localStorage.getItem('token')
  }),
  getters: {
    username() {
      return this.userInfo.name
    }
  },
  actions: {
    setToken(token) {
      this.token = token
    },
    setUserInfo(userInfo) {
      this.userInfo = userInfo
    },
    sysLogin(data) {
      return new Promise((resolve, reject) => {
        if (data.username === 'admin' && data.password === '123456') {
          window.electronAPI.loginSuccess(data)
          // 登录成功后，将token存入本地
          this.setToken(data.username)
          window.localStorage.setItem('token', data.username)
          resolve(true)
        } else {
          window.electronAPI.loginError()
        }
      })
    },
    sysLogout() {
      return new Promise((resolve, reject) => {
        window.electronAPI.logout()
        this.setToken('')
        window.localStorage.removeItem('token')
        resolve(true)
      })
    }
  }
})
export default userStore

菜单收起展开的store

js 复制代码

import { defineStore } from "pinia";
const useSysStore = defineStore("sys", {
  state: () => ({
    collapse: false,
  }),
  getters: {
    isCollapse() {
      return this.collapse;
    },
  },
  actions: {
    toggleCollapse() {
      console.log(this.collapse);
      this.collapse = !this.collapse;
    },
  },
});
export default useSysStore;

打包

bash 复制代码

npm run ele:build

打包文件里面安装到本地即可以使用

注意事项

win11的弹窗是正常显示

如果电脑系统是win10,很可能弹不出右下角的系统弹窗，是系统处于安全角度的考虑，但是mac和win11是没有问题的，这里贴出解决方案。
