Ant Design Vue官方文档
安装Ant Design Vue
npm install ant-design-vue --save
npm install --save @ant-design/icons-vue#自动按需引入组件
npm install unplugin-vue-components -D
修改配置文件vite.config.js
import {fileURLToPath, URL} from 'node:url'import {defineConfig} from 'vite'
import vue from '@vitejs/plugin-vue'
import Components from 'unplugin-vue-components/vite';
import {AntDesignVueResolver} from 'unplugin-vue-components/resolvers';// https://vitejs.dev/config/
export default defineConfig({server: {port: 9000},plugins: [vue(),Components({resolvers: [AntDesignVueResolver({importStyle: false, // css in js}),],}),],resolve: {alias: {'@': fileURLToPath(new URL('./src', import.meta.url))}}
})
修改main.js
import './assets/main.css'import { createApp } from 'vue'
import { createPinia } from 'pinia'
import Antd from 'ant-design-vue';import App from './App.vue'
import router from './router'
import 'ant-design-vue/dist/reset.css';const app = createApp(App)app.use(createPinia())
app.use(router)
app.use(Antd)app.mount('#app')
添加一个测试页面
<script setup>
import {ZoomOutOutlined} from "@ant-design/icons-vue";
</script><template><div class="about"><h1>This is an about page</h1><a-button>测试</a-button><br><ZoomOutOutlined /></div>
</template><style>
</style>
Antd栅格把页面平均分成24份
<template><a-row><a-col :span="24">col</a-col></a-row><a-row><a-col :span="12">col-12</a-col><a-col :span="12">col-12</a-col></a-row><a-row><a-col :span="8">col-8</a-col><a-col :span="8">col-8</a-col><a-col :span="8">col-8</a-col></a-row><a-row><a-col :span="6">col-6</a-col><a-col :span="6">col-6</a-col><a-col :span="6">col-6</a-col><a-col :span="6">col-6</a-col></a-row>
</template>
使用Pinia管理用户状态
刷新页面，Pinia中的数据会丢失，使用Pinia插件做数据持久化
npm install --save zipson
npm install --save pinia-plugin-persistedstate
修改main.js
import './assets/main.css'import { createApp } from 'vue'
import { createPinia } from 'pinia'
import piniaPluginPersistedstate from 'pinia-plugin-persistedstate'
import Antd from 'ant-design-vue';import App from './App.vue'
import router from './router'
import 'ant-design-vue/dist/reset.css';const app = createApp(App)
const pinia = createPinia()
pinia.use(piniaPluginPersistedstate);//pinia数据持久化app.use(pinia)
app.use(router)
app.use(Antd)app.mount('#app')
使用Pinia保存用户状态，添加文件src/stores/user.js
import {reactive} from 'vue'
import {defineStore} from 'pinia'
import {stringify, parse} from 'zipson'const MEMBER = "MEMBER"
export const useUserStore = defineStore('user', () => {const userInfo = reactive({id: '',mobile: '',token: ''})function setUserInfo({id, mobile, token}) {userInfo.id = iduserInfo.mobile = mobileuserInfo.token = token}function clearUserInfo() {userInfo.id = ''userInfo.mobile = ''userInfo.token = ''}return {userInfo, setUserInfo, clearUserInfo}
}, {persist: {key: MEMBER,storage: sessionStorage,// paths: ['count'],serializer: {deserialize: parse,serialize: stringify},beforeRestore: (ctx) => {console.log(`about to restore '${ctx.store.$id}'`)},afterRestore: (ctx) => {console.log(`just restored '${ctx.store.$id}'`)},debug: true,}
})
ite多环境配置
https://vitejs.cn/vite3-cn/guide/env-and-mode.html#env-variables
官方配置文档
在根目录创建文件 .env.development
NODE_ENV=development
#自定义变量需要以VITE_开头
VITE_APP_BASE_URL=http://localhost:8000
生产环境 .env.production
NODE_ENV=production
VITE_APP_BASE_URL=http://train.intmall.com
使用环境变量
axios.defaults.baseURL = import.meta.env.VITE_APP_BASE_URL;
console.log(process.env.NODE_ENV)
console.log(import.meta.env.VITE_APP_BASE_URL)
封装网络请求工具类Axios
npm install axios --save
封装网络请求工具类 src/utils/request.js
import axios from 'axios'
import {notification} from 'ant-design-vue';
import {useUserStore} from '@/stores/user';
import router from '@/router'const {userInfo, clearUserInfo} = useUserStore()
export const serverUrl = import.meta.env.VITE_APP_BASE_URLconst service = axios.create({baseURL: serverUrl,timeout: 5000
})// Add a request interceptor 全局请求拦截
service.interceptors.request.use(function (config) {// Do something before request is sentconst token = userInfo.tokenif (token) {config.headers['token'] = token}// 此处还可以设置tokenreturn config},function (error) {// Do something with request errorreturn Promise.reject(error)}
)// Add a response interceptor 全局相应拦截
service.interceptors.response.use(function (response) {// Any status code that lie within the range of 2xx cause this function to trigger// Do something with response data// 如果是固定的数据返回模式，此处可以做继续完整的封装const resData = response.data || {}if (resData.success) {return resData}notification.error({description: resData.message});return Promise.reject(resData.message)},function (error) {// Any status codes that falls outside the range of 2xx cause this function to trigger// Do something with response error// 此处需要对返回的状态码或者异常信息作统一处理console.log('error', error)const response = error.response;const status = response.status;if (status === 401) {// 判断状态码是401 跳转到登录页console.log("未登录或登录超时，跳到登录页");clearUserInfo()notification.error({description: "未登录或登录超时"});router.push('/login')}return Promise.reject(error)}
)export const get = (url, params) => {return service.get(url, {params})
}export const post = (url, data) => service.post(url, data)export const put = (url, data) => service.put(url, data)export const del = (url, data) => service.delete(url)
遇到的问题：
useRouter失效，router无法跳转页面
https://blog.csdn.net/qq_57700056/article/details/133530562
后台接口调用示例: src/api/userApi.js
import { get, post, put, del } from "../utils/request";// 用户登录
export async function login(data) {return post('/member/member/login', data)
}export async function sendCode(data) {return post('/member/member/sendCode', data)
}export async function getUserCount() {return get('/member/member/count')
}export async function savePassenger(data) {return post('/member/passenger/save', data)
}export async function queryPassengerList(data) {return post('/member/passenger/queryList', data)
}export async function deletePassenger(id) {return del(`/member/passenger/delete/${id}`)
}// 导出 userApi 方法
export default {login,sendCode,getUserCount,savePassenger,deletePassenger,queryPassengerList
}前端页面路由配置
增加路由防卫，判断要跳转的页面是否需要登录
src/router/index.js
由于router挂载比pinia要早，守卫在在使用pinia时，pinia还没有挂载，把pinia写在守卫里面即可解决问题
import {createRouter, createWebHistory} from 'vue-router'
import {notification} from 'ant-design-vue';
import {useUserStore} from '@/stores/user';const router = createRouter({history: createWebHistory(import.meta.env.BASE_URL),routes: [{path: '/',name: 'main',component: () => import('../views/MainView.vue'),children: [{path: '/welcome',name: 'welcome',component: () => import('../views/main/WelcomeView.vue')}, {path: '/passenger',name: 'passenger',component: () => import('../views/main/PassengerView.vue')}]},{path: '/login',name: 'login',component: () => import('../views/LoginView.vue'),meta: {noToken: true}}, {path: '',redirect: '/welcome'}]
})// 路由登录拦截
router.beforeEach((to, from, next) => {// 要不要对meta.noToken属性做监控拦截if (to.matched.some(function (item) {console.log(item, "是否不需要登录校验：", item.meta.noToken || false);return !item.meta.noToken})) {const {userInfo} = useUserStore()console.log("页面登录校验开始：", userInfo);if (!userInfo.token) {console.log("用户未登录或登录超时！");notification.error({description: "未登录或登录超时"});next('/login');} else {next();}} else {next();}

前端跨域问题
前后端分离项目，前端在请求后台接口时会出现跨域问题
这个后端项目使用到了gateway，在配置文件中加入：
# 允许请求来源（老版本叫allowedOrigin）
spring.cloud.gateway.globalcors.cors-configurations.[/**].allowedOriginPatterns=*
# 允许携带的头信息
spring.cloud.gateway.globalcors.cors-configurations.[/**].allowedHeaders=*
# 允许的请求方式
spring.cloud.gateway.globalcors.cors-configurations.[/**].allowedMethods=*
# 是否允许携带cookie
spring.cloud.gateway.globalcors.cors-configurations.[/**].allowCredentials=true
# 跨域检测的有效期，会发起一个OPTION请求
spring.cloud.gateway.globalcors.cors-configurations.[/**].maxAge=3600后端分页查询方法
#CommonPageParam.java
@Data
public class CommonPageParam {@NotNull(message = "页码不能为空")private Integer page;@NotNull(message = "每页数量不能为空")@Max(value = 100, message = "分页条数不能超过100")private Integer limit;
}#PassengerQueryReq.java
@Data
public class PassengerQueryReq extends CommonPageParam {private Long memberId;
}#CommonPageResp.java
@Data
@NoArgsConstructor
public class CommonPageResp<T> {/** 默认每页的条数 */public static final int PAGE_SIZE_DEFAULT = 10;/*** 业务上的成功或失败*/private boolean success = true;/*** 返回信息*/private String message;/*** 返回泛型数据，自定义类型*/private List<T> data;/*** 总数*/private Long count;/*** 页码*/private Integer page;/*** 每页数量*/private Integer limit;public Integer getPage() {if (page == null || page < 1) {return 1;}return page;}public Integer getLimit() {if (limit == null) {return PAGE_SIZE_DEFAULT;}return limit;}public static <T> CommonPageResp<T> SUCCESS(String message, List<T> data, PageInfo pageInfo) {return new CommonPageResp<>(true, message, data, pageInfo.getTotal(), pageInfo.getPageNum(), pageInfo.getPageSize());}public CommonPageResp(boolean success, String message, List<T> data, Long count, Integer page, Integer limit) {this.success = success;this.message = message;this.data = data;this.count = count;this.page = page;this.limit = limit;}
