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-buttonloading/></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-buttonloading/></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-buttonloading/></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 .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);

}.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-itemfield="name"tooltip="Please enter username"label="账号"class="element":rules= "rules"><a-inputv-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-inputv-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-itemfield="name"tooltip="Please enter username"label="账号"class="element":rules="rules"><a-inputv-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-inputv-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?

];
const renderIcon = () => h(IconExclamationCircleFill);
const login = async()=>{let result = await userLoginService(loginData.value);renderIcon(result.msg?result.msg:'登录成功');

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。
