超详细的前后端实战项目(Spring系列加上vue3)前端篇(一)(一步步实现+源码)

Heath-ceTide竹心 2024-06-26 16:03:02 阅读 77

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>

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

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>

/* 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">

</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">

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。
