最近想着一步步搭建一个前后端项目,将每一步详细的做出来。(如果有不足或者建议,也希望大佬们指出哦)

前端初始化

1.根据vue脚手架创建vue项目

这里可以用很多方法创建vue项目,大家看着创建吧,只要能创建出来就可以了(用的vue3)

这里我加了router和vuex,emm,就不用ts了(感觉还是js用的更好一点)

OK,项目创建完毕,即可开始写前端代码了。

2.安装依赖:

        1.挑一个自己喜欢的组件库引用一手,这里我选用arco design(也没必要只用Element-ui,可以试试其他的)

npm install --save-dev @arco-design/web-vue

OKOK,开始下载

安装好了之后,我们还要安装一些必要的依赖,比如axios,sass这些,emmmm,目前就安装这几个吧。

npm install axios

npm install sass -D

然后根据组件库官网的操作进行引入

import { createApp } from 'vue' import ArcoVue from '@arco-design/web-vue'; import App from './App.vue'; import '@arco-design/web-vue/dist/arco.css';  const app = createApp(App); app.use(ArcoVue); app.mount('#app');

改造一下main.js中的代码

import { createApp } from 'vue' import App from './App.vue' import router from './router' import store from './store' import ArcoVue from '@arco-design/web-vue'; import '@arco-design/web-vue/dist/arco.css';   createApp(App).use(store).use(ArcoVue).use(router).mount('#app') 

注意注意引入组件库之后,可以找个组件看看能不能使用该组件库,以防万一;

呐,这里我们就去官网看看

很好,就是你了,表单布局,我们点击其下方代码,将其放入App.vue试试能不能用

好嘞,随机找一串串代码放到App.vue中试试(不要试着从图片中照抄我的哈,自己去官网找一个试试Arco Design Vue)咱,主打一个快速。

嚯,出现了!那么组件库是能用哒!

好,第二步也就完成了。

这里我建议每做几步就开启调试一下。

3.调整目录,初始化项目:

        1.清空components(把HelloWorld.vue删了)

        2.新建目录api,utils,views

        3.把App.vue中用不到的代码都给删了,留一个  <router-view />就好了,然后,把router的index.js的代码全给注释了(emmm,直接删了感觉太麻烦,注释了后面写起来好做参照)

目前的目录结构就是这样了;

(App.vue就变成这样啦)

4.定义请求工具:

大家不要一开始写前端就直奔优美的”可跳转“页面,这边先整体规定一个向后端发请求的工具request.js

        在utils目录下创建request.js文件:

import axios from 'axios';//导入axios //定义前缀 const URL = 'http://localhost:8080'; const instance = axios.create({URL})   //来一个响应拦截器 instance.interceptors.response.use(     result=>{         if(result.data.code == 0){             return result.data;         }         //如果不为0则表示失败         alert(result.data.message||'出现错误')         return Promise.reject(err);//异步的状态转化成失败的状态     },     err=>{         alert('服务异常');         return Promise.reject(err);//异步的状态转化成失败的状态     } ) export default instance;

解释一下这段代码:引入发请求的axios,然后定义一个开发时期的请求必有前缀(这里直接写http://localhost:8080其实是有问题的,对于后面出现的跨域问题....emmmm,其实前端后端都有方式解决,看情况吧,后面再讲),做一个相应拦截器,对结果进行判断,然后导出

(这里需要提示一下统一相应有哪些(不然可能会不太好理解))

后端那一块统一相应数据:code:0表示成功,1表示失败;msg: 提示信息;data:数据

前端代码编写开始!!

OK啊各位,初始化完成我们便要开始编写代码了。

首先,我们先明确一波步骤:

        确定布局  --> 填充各部分代码 -->  后端插入

(如果涉及与后端的交互,遵循以下步骤

        1.搭建页面(html,css)-> 2.绑定数据与事件 -> 3.调用后端接口)

好嘞,熟悉了吗各位,不熟练也没事,我们先找一个练练手。

先从组件库这里找到布局:

这布局,看似普通,实则帅的雅痞,就它了。引入代码

回到目录component下,创建一个新的文件GlobalPage.vue

(众所周知的小技巧:<vue>可快速构建vue文件)

<template>    <a-layout style="height: 400px;">       <a-layout-header>Header</a-layout-header>       <a-layout>         <a-layout-sider theme="dark">Sider</a-layout-sider>         <a-layout-content>Content</a-layout-content>       </a-layout>       <a-layout-footer>Footer</a-layout-footer>     </a-layout> </template>  <script> export default {  } </script>  <style scoped> .layout-demo :deep(.arco-layout-header), .layout-demo :deep(.arco-layout-footer), .layout-demo :deep(.arco-layout-sider-children), .layout-demo :deep(.arco-layout-content) {   display: flex;   flex-direction: column;   justify-content: center;   color: var(--color-white);   font-size: 16px;   font-stretch: condensed;   text-align: center; }   .layout-demo :deep(.arco-layout-header), .layout-demo :deep(.arco-layout-footer) {   height: 64px;   background-color: var(--color-primary-light-4); }  .layout-demo :deep(.arco-layout-sider) {   width: 206px;   background-color: var(--color-primary-light-3); }  .layout-demo :deep(.arco-layout-content) {   background-color: rgb(var(--arcoblue-6)); } </style>

然后我们改一下index.js文件(将GlobalPage引入)(要是看着那些注解感觉不美观的话就直接删了)

import { createRouter, createWebHashHistory } from 'vue-router' import MainPage from '../components/GlobalPage.vue'  const routes = [   // {   //   path: '/',   //   name: 'home',   //   component: HomeView   // },   // {   //   path: '/about',   //   name: 'about',   //   // route level code-splitting   //   // this generates a separate chunk (about.[hash].js) for this route   //   // which is lazy-loaded when the route is visited.   //   component: () => import(/* webpackChunkName: "about" */ '../views/AboutView.vue')   // }   {     path: '/',     name: 'mainPage',     component: MainPage   } ]  const router = createRouter({   history: createWebHashHistory(),   routes })  export default router 

运行一手看看(记得每次有一些大改就要看看情况,改多再看就会很麻烦,bug也不好排查)

运行出来就是这么个界面

搭建Header和Footer代码

先把头部和尾部的代码解决了。

先来尾部吧,我觉得这个比较简单(哈)

一般来说,网站的底部都是一些网站运营的介绍什么的(大多都是哈,也不一定全是)

这里我就以大家都爱的4399为例(大多都是哈,也不一定全是,哈哈哈)

emmm,这里我们可以把Footer这一块封装为一个组件,因为虽然定义的GlobalPage属于是全局的页面,但万一之后会跳转到其他的页面呢,这里我觉得封装成组件更好一些(看起来也更轻巧一些)

在views目录下创建GlobalFooter.vue

<template>   <div id="header">由Heath ceTide 创作的网站 XXX 有限公司</div> </template>  <script> export default {}; </script>  <style> #header {   font-family: "Satisfy", cursive;   font-size: 16px;   color: rgb(102, 149, 164);   margin-right: 20px; } </style>

差不多了,将其替换掉GlobalPage的header

<template>    <a-layout style="height: 400px;">       <a-layout-header>Header</a-layout-header>       <a-layout>         <a-layout-sider theme="dark">Sider</a-layout-sider>         <a-layout-content>Content</a-layout-content>       </a-layout>       <a-layout-footer>         <global-footer></global-footer>       </a-layout-footer>     </a-layout> </template> <script> import GlobalFooter from '../views/GlobalFooter.vue' export default {   components: { GlobalFooter },  } </script>

展示出了样式就行了,(之后可以美化以下),好,然后我们开始整Header,

这一块导航栏,我觉得吧,还是用组件比较合适(倒不是不会整,毕竟也麻烦,不用自己手敲的绝不自己手敲代码)

就选这个深色模式导航啦,新建GlobalHeader.vue文件把代码用CV大法放进去

<template>   <div class="menu-demo">     <a-menu mode="horizontal" theme="dark" :default-selected-keys="['1']">       <a-menu-item key="0" :style="{ padding: 0, marginRight: '38px' }" disabled>         <div           :style="{             width: '80px',             height: '30px',             background: 'var(--color-fill-3)',             cursor: 'text',           }"         />       </a-menu-item>       <a-menu-item key="1">Home</a-menu-item>       <a-menu-item key="2">Solution</a-menu-item>       <a-menu-item key="3">Cloud Service</a-menu-item>       <a-menu-item key="4">Cooperation</a-menu-item>     </a-menu>   </div> </template> <style scoped> .menu-demo {   box-sizing: border-box;   width: 100%;   background-color: var(--color-neutral-2); } </style> 
<template>   <a-layout style="height: 400px">     <a-layout-header><global-header></global-header></a-layout-header>     <a-layout>       <a-layout-sider theme="dark">Sider</a-layout-sider>       <a-layout-content>Content</a-layout-content>     </a-layout>     <a-layout-footer>       <global-footer class="footer"></global-footer>     </a-layout-footer>   </a-layout> </template>  <script> import GlobalFooter from "../views/GlobalFooter.vue"; import GlobalHeader from "../views/GlobalHeader.vue"; export default {   components: { GlobalFooter, GlobalHeader }, }; </script>  <style scoped> .layout-demo :deep(.arco-layout-header), .layout-demo :deep(.arco-layout-footer), .layout-demo :deep(.arco-layout-sider-children), .layout-demo :deep(.arco-layout-content) {   display: flex;   flex-direction: column;   justify-content: center;   color: var(--color-white);   font-size: 16px;   font-stretch: condensed;   text-align: center; }  .layout-demo :deep(.arco-layout-header), .layout-demo :deep(.arco-layout-footer) {   height: 64px;   background-color: var(--color-primary-light-4); }  .layout-demo :deep(.arco-layout-sider) {   width: 206px;   background-color: var(--color-primary-light-3); }  .layout-demo :deep(.arco-layout-content) {   background-color: rgb(var(--arcoblue-6)); }  .footer {   background-color: aliceblue;   padding: 16px;   position: sticky;   bottom: 0;   left: 0;   right: 0;   text-align: center;   letter-spacing: 3px; } </style>

其实这个空的区域可以加一个logo或者其他什么的

呐,就像这样

OK,目前的页面就是这个样子了;

搭建搜索页面

好的,下面整一个全局的搜索框页面吧

创建一个SearchPage.vue 文件

从组件库中找到一个合适的搜索框

<!--SearchPage.vue代码--> <template>   <a-space direction="vertical" size="large">     <a-input-search       :style="{ width: '320px' }"       placeholder="Please enter something"       button-text="Search"       search-button     />   </a-space> </template>  <script> export default {}; </script>  <style> </style>

将新组件放到GlobalPage中(暂时的,之后还是要处理路由的)

<template>   <a-layout style="height: 400px">     <a-layout-header><global-header></global-header></a-layout-header>     <a-layout>       <a-layout-sider theme="dark">Sider</a-layout-sider>       <a-layout-content><search-page></search-page></a-layout-content>     </a-layout>     <a-layout-footer>       <global-footer class="footer"></global-footer>     </a-layout-footer>   </a-layout> </template>  <script> import GlobalFooter from "../views/GlobalFooter.vue"; import GlobalHeader from "../views/GlobalHeader.vue"; import SearchPage from '../views/SearchPage.vue'; export default {   components: { GlobalFooter, GlobalHeader, SearchPage }, }; </script>

现在搜索框就出来了,(这里最右边加了一点点小细节(不重要)之后会把代码发出来)

这里其实可以加一个搜索框等待效果

<template>   <div id="search">     <a-space direction="vertical" size="large">       <a-input-search         :style="{ width: '320px' }"         placeholder="Please enter something"         button-text="Search"         search-button       />     </a-space>     <a-space direction="vertical" size="large">       <a-input-search         :style="{ width: '320px' }"         placeholder="Please enter something"         button-text="Search"         search-button         loading       />     </a-space>   </div> </template>  <script> export default {}; </script>  <style> </style>

这里其实是复制了两个搜索框代码,不过另外一个加上了loading属性,这样就能表现出等待中的效果

呐呐呐,就是这样,然后我们再用v-if定义一下它的显示和隐藏就可以了

ok,演示一下:

先设置script 为setup,然后引入ref

<script setup> import {ref} from 'vue';

 还记得之前说的三部曲吗: 1.搭建页面(html,css)-> 2.绑定数据与实践 -> 3.调用后端接口)

那我们以及写好了搜索框了,也该进行数据绑定了(这里暂时不进行后端接口调用,(毕竟还没开发))

对于一个组件的显示和隐藏我们直接写

<script setup> import {ref} from 'vue'; const isSearch = ref(false)  

然后呢,两个搜索框绑定该属性(一个是isSearch,一个是!isSearch),这样就能保持一个显示,一个隐藏了。那么,如何实现转换呢,平时在搜索的时候,当我们点击了搜索按钮的时候就会出现转换效果,如果网比较好的话,估计也就直接跳转了,(如果网不好的话,搜索框转圈转了一会儿就会恢复原样)

那么,我们定义一个函数,在正常情况下点击搜索的时候触发,转换为搜索中的样式,然后过几秒就恢复原状。

那么开始定义吧;

<script setup> import {ref} from 'vue'; const isSearch = ref(false)   const onSearch = () => {   isSearch.value = true;   setTimeout(() => {     isSearch.value = false;   }, 5000); }; </script>

这里定义了一个函数,点击之后,isSearch改变,等到五秒之后,值恢复。来试试吧

<template>   <div id="search">     <a-space direction="vertical" size="large" v-if="!isSearch">       <a-input-search         :style="{ width: '320px' }"         placeholder="Please enter something"         button-text="Search"         search-button         @click=onSearch       />     </a-space>     <a-space direction="vertical" size="large" v-if="isSearch">       <a-input-search         :style="{ width: '320px' }"         placeholder="Please enter something"         button-text="Search"         search-button         loading       />     </a-space>   </div> </template>  <script setup> import {ref} from 'vue'; const isSearch = ref(false)   const onSearch = () => {   isSearch.value = true;   setTimeout(() => {     isSearch.value = false;   }, 5000); }; </script>

成功了,那再来完善一下

有搜索框,当然要有显示搜索内容的区域,

再去组件库看看有没有什么合适的

就用这个吧,

<template>   <div id="searchPage">          <div class="search">       <a-space direction="vertical" size="large" v-if="!isSearch">         <a-input-search           :style="{ width: '620px' }"           placeholder="Please enter something"           button-text="Search"           search-button           @click="onSearch"         />       </a-space>       <a-space direction="vertical" size="large" v-if="isSearch">         <a-input-search           :style="{ width: '620px' }"           placeholder="Please enter something"           button-text="Search"           search-button           loading         />       </a-space>     </div>     <a-space direction="vertical" size="large">       <a-radio-group v-model="type" type="button">         <a-radio value="line">Line</a-radio>         <a-radio value="card">Card</a-radio>         <a-radio value="card-gutter">Card Gutter</a-radio>         <a-radio value="text">Text</a-radio>         <a-radio value="rounded">Rounded</a-radio>         <a-radio value="capsule">Capsule</a-radio>       </a-radio-group>       <a-radio-group v-model="size" type="button">         <a-radio value="mini">Mini</a-radio>         <a-radio value="small">Small</a-radio>         <a-radio value="medium">Medium</a-radio>         <a-radio value="large">Large</a-radio>       </a-radio-group>       <a-tabs :type="type" :size="size">         <a-tab-pane key="1" title="Tab 1"> Content of Tab Panel 1 </a-tab-pane>         <a-tab-pane key="2" title="Tab 2"> Content of Tab Panel 2 </a-tab-pane>         <a-tab-pane key="3" title="Tab 3"> Content of Tab Panel 3 </a-tab-pane>       </a-tabs>     </a-space>   </div> </template>  <script setup> import { ref } from "vue"; const isSearch = ref(false);  const onSearch = () => {   isSearch.value = true;   setTimeout(() => {     isSearch.value = false;   }, 5000); }; </script>  <style scoped> .search{     margin: 30px auto;  } </style>

添加代码并做一些优化

目前就是这个样子了。

emmm,感觉不太对,好像有点快了,要不还是做一个登录注册页面吧。。。

搭建登录注册页面

创建LoginPage.vue

这一块我觉得还挺容易的,先给个示例代码吧

<template>   <div class="container">     <div class="login-box">       <!-- Login Form -->       <form action="">         <h2>Login</h2>         <div class="input-box">           <span class="icon"><i class="fa-solid fa-envelope"></i></span>           <input type="email" required placeholder="Email" />         </div>         <div class="input-box">           <span class="icon"><i class="fa-solid fa-lock"></i></span>           <input type="password" placeholder="Password" required />         </div>         <div class="remember-forget">           <label><input type="checkbox" />Remember Me</label>           <a href="#">Forgot Password?</a>         </div>         <button type="submit">Login</button>         <div class="register-link">           <a href="#">Don't have an account? Create Now!</a>         </div>       </form>     </div>   </div> </template>  <script> export default {  } </script>  <style scoped> * {   margin: 0;   padding: 0;   box-sizing: border-box;   font-family: "Poppins", sans-serif; } .container {   width: 100%;   height: 100vh;   background: url("../assets/background.jpg") no-repeat;   background-size: cover;   background-position: center;   display: flex;   justify-content: center;   align-items: center; }  .container .login-box {   position: relative;   width: 390px;   height: 420px;   background-color: transparent;   border: 2px solid rgba(255, 255, 255, 0.5);   border-radius: 20px;   display: flex;   justify-content: center;   align-items: center;   backdrop-filter: blur(15px); }  .login-box h2 {   font-size: 28px;   color: #fff;   text-align: center; }  .login-box .input-box {   position: relative;   width: 310px;   margin: 30px 0;   border-bottom: 2px solid #fff; }  .input-box input {   width: 100%;   height: 50px;   background: transparent;   border: none;   outline: none;   font-size: 16px;   color: #fff;   padding: 0 35px 0 5px; }  .input-box input::placeholder {   color: #f9f9f9; }  .input-box .icon {   position: absolute;   right: 8px;   color: #fff;   font-size: 18px;   line-height: 50px; }  .login-box .remember-forget {   margin: -15px 0 15px;   font-size: 15px;   color: #fff;   display: flex;   justify-content: space-between; }  .remember-forget label input {   margin-right: 3px; }  .login-box button {   width: 100%;   height: 40px;   background: #fff;   border: none;   outline: none;   border-radius: 40px;   cursor: pointer;   font-size: 16px;   color: #000;   transition: all 0.5s; }  .login-box button:hover {   background: #1f73c9;   color: #fff; }  .login-box .register-link {   font-size: 15px;   color: #fff;   text-align: center;   margin: 20px 0 10px; }  .remember-forget a, .register-link a {   color: #fff;   text-decoration: none; }  .remember-forget a:hover, .register-link a:hover {   text-decoration: underline; }  /* Responsive Design */ @media (max-width: 460px) {   .container .login-box {     width: 350px;   }    .login-box .input-box {     width: 290px;   } }  @media (max-width: 360px) {   .container .login-box {     width: 100%;     height: 100vh;     border: none;   } } </style>

这一块代码是之前找到的一个登录页代码,我觉着就还挺好

不过吧,我决定还是不用这个代码,去组件库上找找吧(主要还是要加深一下组件库的使用)

好了就用这个

小改一下吧;

emmm,这代码可谓一坨(发出来也需要些勇气啊。。)

大家如果有自己的写的规范代码就用自己的(hhh)

那么,我们开始前面的三部曲:搭建页面以及完成,可以开始绑定数据与事件了。

<script setup> import {ref} from 'vue'; const loginData = ref({     username: '',     password: '',     isRead: false, })

先引入ref,然后创建loginData,然后v-model绑定数据

<template>   <div class="container">     <div class="login-box">       <a-form         :model="loginData"         :style="{ width: '600px' }"         @submit="handleSubmit"         class="input-box"       >         <h2 style="margin-bottom: 60px">Login</h2>         <a-form-item           field="name"           tooltip="Please enter username"           label="账号"           class="element"           :rules= "rules"         >           <a-input             v-model="loginData.username"             placeholder="please enter your username..."             style="margin-right: 40px"           />         </a-form-item>         <a-form-item field="post" label="密码" class="element" :rules= "rules">           <a-input             v-model="loginData.password"             placeholder="please enter your password..."             style="margin-right: 40px"           />         </a-form-item>         <a-form-item field="isRead">           <a-checkbox v-model="loginData.isRead">             I have read the manual           </a-checkbox>         </a-form-item>         <a-form-item>           <a-button html-type="submit" class="input-box">Submit</a-button>         </a-form-item>         <div class="register-link">           <a href="#">Don't have an account? Create Now!</a>         </div>       </a-form>     </div>   </div> </template> <script setup> import {ref} from 'vue'; const loginData = ref({     username: '',     password: '',     isRead: false, }) const rules = [{       validator: (value, cb) => {         return new Promise(resolve => {           window.setTimeout(() => {             if (value !== ' ') {               cb('content not empty')             }             resolve()           }, 1000)         })       }     }];  </script>  <style scoped> * {   margin: 0;   padding: 0;   box-sizing: border-box;   font-family: "Poppins", sans-serif;   display: flex;   justify-content: center; } .container {   width: 100%;   height: 100vh;   background: url("../assets/background.jpg") no-repeat;   background-size: cover;   background-position: center;   display: flex;   justify-content: center;   align-items: center; }  .container .login-box {   position: relative;   width: 500px;   height: 580px;   background-color: transparent;   border: 2px solid rgba(255, 255, 255, 0.5);   border-radius: 20px;   display: flex;   justify-content: center;   align-items: center;   backdrop-filter: blur(15px); }  .login-box h2 {   font-size: 28px;   color: #fff;   text-align: center; }  .login-box .input-box {   position: relative;   width: 310px;   margin: 30px 0; }  .input-box input {   width: 80%;   height: 60px;   background: transparent;   border: none;   outline: none;   font-size: 16px;   color: #fff;   padding: 0 2px 0 5px; }  .input-box input::placeholder {   color: #f9f9f9; }  .input-box .icon {   position: absolute;   right: 8px;   color: #fff;   font-size: 16px;   line-height: 25px; }  .login-box .remember-forget {   margin: -15px 0 15px;   font-size: 15px;   color: #fff;   display: flex;   justify-content: space-between; }  .remember-forget label input {   margin-right: 30px; }  .login-box button {   width: 100%;   height: 40px;   background: #fff;   border: none;   outline: none;   border-radius: 40px;   cursor: pointer;   font-size: 16px;   color: #000;   transition: all 0.5s; }  .login-box button:hover {   background: #1f73c9;   color: #fff; }  .login-box .register-link {   font-size: 15px;   color: #fff;   text-align: center;   margin: 5px 0 5px; }  .remember-forget a, .register-link a {   color: #fff;   text-decoration: none; }  .remember-forget a:hover, .register-link a:hover {   text-decoration: underline; }  /* Responsive Design */ @media (max-width: 460px) {   .container .login-box {     width: 350px;   }    .login-box .input-box {     width: 290px;   } }  @media (max-width: 360px) {   .container .login-box {     width: 100%;     height: 100vh;     border: none;   } } .element {   margin: 20px 0; } </style>

这里可以添加一个校验规则,

在组件库这里找一下表单的校验规则

<script setup> import {ref} from 'vue'; const loginData = ref({     username: '',     password: '',     isRead: false, }) const rules = [{       validator: (value, cb) => {         return new Promise(resolve => {           window.setTimeout(() => {             if (value === ' ') {               cb('content not empty')             }             resolve()           }, 1000)         })       }     }];  </script>

随便定义了一个,大家可以自己定义看看,(emmm,这里我感觉element-ui的校验规则更好一丢丢)。

好了,既然定义好了登录界面,就可以试试向后端发起请求了。

这里开始在api文件夹下面创建一个文件user.js然后编写一个登录接口函数

import request from '../utils/request'  //创建一个调用登录接口函数 export const userLoginService = (loginData) =>{     //用urlSearchParams完成传递     const params = new URLSearchParams()     for(let key in loginData){         params.append(key,loginData[key]);     }     return request.post('/user/login',params); }

定义之后就去登录页调用

        <a-form-item>           <a-button html-type="submit" class="input-box" @click="login"             >Submit</a-button           >         </a-form-item>

在submit提交这里加上@click="login"

然后定义方法:(获取信息,如果msg提示信息不为0,则显示消息,为0就表示登陆成功)

const login = async()=>{     let result = await userLoginService(loginData.value);     alert(result.msg?result.msg:'登录成功'); }

不过,这里用浏览器默认的alert感觉不太美观啊,毕竟都用组件库了,

消息类型:就决定是你了!

引入一手修改代码,

<script setup> import { h } from 'vue'; import { IconExclamationCircleFill } from '@arco-design/web-vue/es/icon'; import { ref } from "vue"; import {userLoginService} from '../api/user' const loginData = ref({   username: "",   password: "",   isRead: false, });   const rules = [   {     validator: (value, cb) => {       return new Promise((resolve) => {         window.setTimeout(() => {           if (value !== " ") {             cb("content not empty");           }           resolve();         }, 1000);       });     },   }, ]; const renderIcon = () => h(IconExclamationCircleFill); const login = async()=>{     let result = await userLoginService(loginData.value);     renderIcon(result.msg?result.msg:'登录成功'); }  </script>

好,感觉这样也就差不多了,下面展示一下登录页代码

<template>   <div class="container">     <div class="login-box">       <a-form         :model="loginData"         :style="{ width: '600px' }"         @submit="handleSubmit"         class="input-box"       >         <h2 style="margin-bottom: 60px">Login</h2>         <a-form-item           field="name"           tooltip="Please enter username"           label="账号"           class="element"           :rules="rules"         >           <a-input             v-model="loginData.username"             placeholder="please enter your username..."             style="margin-right: 40px"           />         </a-form-item>         <a-form-item field="post" label="密码" class="element" :rules="rules">           <a-input             v-model="loginData.password"             placeholder="please enter your password..."             style="margin-right: 40px"           />         </a-form-item>         <a-form-item field="isRead">           <a-checkbox v-model="loginData.isRead">             I have read the manual           </a-checkbox>         </a-form-item>         <a-form-item>           <a-button html-type="submit" class="input-box" @click="login"             >Submit</a-button           >         </a-form-item>         <div class="register-link">           <a href="#">Don't have an account?

好了,今天的前端就忙碌到这里吧(下一篇文章再见)。

总结一下:1.完成了前端初始化4步,2.完成了全局页面的布局,3.完成了搜索页的代码,和登录页的代码。
