来源：互联网 发布：万能电视遥控器软件 编辑：程序博客网 时间：2024/06/05 06:46

上一篇中已将完成了基础结构的搭建，这一篇将开始正式开发。页面直接使用了一位小伙伴的源码，可以在https://github.com/taylorchen709/vue-admin下载

修改入口main.js

在入口函数中添加对element-ui,vue-router,vuex,vue-source等组件的引用

  1. import Vue from 'vue'
  2. import App from './App'
  3. import ElementUI from 'element-ui'
  4. import 'element-ui/lib/theme-default/index.css'
  5. import VueRouter from 'vue-router'
  6. import store from './vuex/store'
  7. import Vuex from 'vuex'
  8. import VueSource from 'vue-resource'
  9. import routes from './routes'
  10. import 'font-awesome/css/font-awesome.min.css'
  13. Vue.use(ElementUI)
  14. Vue.use(VueRouter)
  15. Vue.use(Vuex)
  16. Vue.use(VueSource)
  18. //创建路由实例
  19. const router = new VueRouter({
  20.     routes
  21. })
  22. router.beforeEach((to, from, next) => {
  24.     //这里进行了简单的登录验证
  25.     //访问login时直接清除user
  26.     if (to.path == '/login') {
  27.         sessionStorage.removeItem('user');
  28.     }
  30.     let user = JSON.parse(sessionStorage.getItem('user'));
  31.     if (!user && to.path != '/login') {
  32.         next({ path: '/login' })
  33.     } else {
  34.         next()
  35.     }
  36. })
  39. new Vue({
  40.     router,
  41.     store,
  42.     render: h => h(App)
  43. }).$mount('#app')

修改App.vue

  1. <template>
  2.     <div id="app">
  3.         <transition name="fade"
  4.                     mode="out-in">
  5.             <router-view></router-view>
  6.         </transition>
  7.     </div>
  8. </template>
  9. <script>
  10.     export default {
  11.         name: 'app',
  12.         components: {
  13.         }
  14.     }
  15. </script>

增加viewes文件夹，并增加模块视图

login.vue

  1. <template>
  2.     <el-form :model="ruleForm2" :rules="rules2" ref="ruleForm2" label-position="left" label-width="0px" class="demo-ruleForm login-container">
  3.         <h3 class="title">系统登录</h3>
  4.         <el-form-item prop="account">
  5.             <el-input type="text" v-model="ruleForm2.account" auto-complete="off" placeholder="账号"></el-input>
  6.         </el-form-item>
  7.         <el-form-item prop="checkPass">
  8.             <el-input type="password" v-model="ruleForm2.checkPass" auto-complete="off" placeholder="密码"></el-input>
  9.         </el-form-item>
  10.         <el-checkbox v-model="checked" checked class="remember">记住密码</el-checkbox>
  11.         <el-form-item style="width:100%;">
  12.             <el-button type="primary" style="width:100%;" @click.native.prevent="handleSubmit2" :loading="logining">登录</el-button>
  13.         </el-form-item>
  14.     </el-form>
  15. </template>
  17. <script>
  18.     export default {
  19.         data() {
  20.             return {
  21.                 logining: false,
  22.                 ruleForm2: {
  23.                     account: 'admin',
  24.                     checkPass: '123456'
  25.                 },
  26.                 rules2: {
  27.                     account: [
  28.                         { required: true, message: '请输入账号', trigger: 'blur' },
  29.                         //{ validator: validaePass }
  30.                     ],
  31.                     checkPass: [
  32.                         { required: true, message: '请输入密码', trigger: 'blur' },
  33.                         //{ validator: validaePass2 }
  34.                     ]
  35.                 },
  36.                 checked: true
  37.             };
  38.         },
  39.         methods: {
  40.             handleReset2() {
  41.                 this.$refs.ruleForm2.resetFields();
  42.             },
  43.             handleSubmit2(ev) {
  44.                 var _this = this;
  45.                 this.$refs.ruleForm2.validate((valid) => {

此时编译运行可以看到下面的页面，由于还没有开发子页面，所以只显示主页和菜单： 

添加模拟的后端API

这里模拟用户管理的功能。为.net开发，具体的开发流程不在赘述。 
UserInfo.cs

  1. public class UserInfo
  2. {
  3.     public string uuid { get; set; }
  4.     public string login_name { get; set; }
  5.     public string real_name { get; set; }
  6.     public string email { get; set; }
  7.     public string birthday { get; set; }
  8.     public int age { get; set; }
  9. }

UserInfoRepository.cs

  1. public class UserInfoRepository
  2. {
  3.     static List<UserInfo> db_users = new List<UserInfo>() {
  5.     };
  7.     public static IList<UserInfo> LoadAll() {
  8.         return db_users;
  9.     }
  10.     public static string Insert(UserInfo u)
  11.     {
  12.         u.uuid = Guid.NewGuid().ToString();
  13.         db_users.Add(u);
  14.         return u.uuid;
  15.     }
  16.     public static string Update(UserInfo u)
  17.     {
  18.         db_users.Remove(db_users.Where(m => m.uuid.Equals(u.uuid)).FirstOrDefault());
  19.         db_users.Add(u);
  20.         return u.uuid;
  21.     }
  22.     public static UserInfo Get(string uuid) {
  23.         return db_users.Where(m=>m.uuid.Equals(uuid)).FirstOrDefault();
  24.     }
  25.     public static void Delete(string uuid)
  26.     {
  27.         var u = db_users.Where(m => m.uuid.Equals(uuid)).FirstOrDefault();
  28.         db_users.Remove(u);
  29.     }
  31. }

UserController.cs

  1. [Route("api/[controller]")]
  2. public class UsersController : Controller
  3. {
  4.     [HttpGet]
  5.     public string Get()
  6.     {
  7.         return JsonConvert.SerializeObject(UserInfoRepository.LoadAll());
  8.     }
  10.     [HttpGet("{uuid}")]
  11.     public string Get(string uuid)
  12.     {
  13.         return JsonConvert.SerializeObject(UserInfoRepository.Get(uuid));
  14.     }
  16.     [HttpGet("p/")]
  17.     public string Get(string name, int page = 1, int pagesize = 20)
  18.     {
  19.         long count = 0;
  20.         var list = UserInfoRepository.LoadAll();
  21.         count = list.Count;
  22.         var obj = new
  23.         {
  24.             total = count,
  25.             list = list.Where(m => m.real_name.Equals(name)).Skip((page - 1) * pagesize).Take(pagesize)
  26.         };
  27.         return JsonConvert.SerializeObject(obj);
  28.     }
  30.     [HttpPost]
  31.     public void Post([FromBody]UserInfo user)
  32.     {
  33.         UserInfoRepository.Insert(user);
  34.     }
  36.     [HttpPut]
  37.     public void Put([FromBody]UserInfo user)
  38.     {
  39.         UserInfoRepository.Update(user);
  40.     }
  42.     [HttpDelete("{uuid}")]
  43.     public void Delete(string uuid)
  44.     {
  45.         UserInfoRepository.Delete(uuid);
  46.     }
  47. }

添加列表页面

  116.                 }
  117.         },
  118.         mounted() {

添加路由，在系统管理的children下添加users

  1. {
  2.     path: '/',
  3.     component: Home,
  4.     name: '系统管理',
  5.     iconCls: 'el-icon-setting',//图标样式class
  6.     children: [
  7.         {path: '/users', component: Users, name: '用户管理' }
  8.     ]
  9. }

同样的方式增加用户添加和编辑页面，完成用户管理小模块。

总结

我们完成了在.net core下基于vue开发单页应用，这种方法实际上是利用webpack的打包功能，编译时将应用打包好，.net应用的cshtml页面再引用已打包的js文件。方案缺陷之一为：每次修改页面都需要重新build，不能同使用Node开发时实时预览页面，在实际的项目中可能并不会使用这种方式，仅供折腾。下面附上源码地址：
