?1、创建项目
使用vue-ts模板创建项目
npm create vite my-vue-app --template vue-ts
?项目目录截图
2、安装和配置vue-router
2.1、安装vue-router
npm install vue-router@4 -S2.2、配置vue-router
2.2.1、在src创建router文件夹并且在router文件夹下创建index.ts文件
import { createRouter, createWebHistory, RouteRecordRaw } from "vue-router";
const routes: Array<RouteRecordRaw> = [
{
path: "/",
name: "home",
/** 在src/views 文件下创建home文件 */
component: () => import("../views/home/index.vue"),
},
{
path: "/about",
name: "about",
/** 在src/views 文件下创建about文件 */
component: () => import("../views/about/index.vue"),
},
];
const router = createRouter({
history: createWebHistory(),
routes,
});
export default router;2.2.2、在main.ts文件中添加router引用
import { createApp } from 'vue'
/** --- 新增代码块 start --- */
import router from './router';
/** --- 新增代码块 end --- */
import './style.css'
import App from './App.vue'
/** --- 修改代码块 end --- */
const app = createApp(App);
app.use(router);
app.mount('#app')
/** --- 修改代码块 start --- */2.2.3、修改App.vue，删除之前代码，改成如下代码块
<template>
<div>
<router-view></router-view>
</div>
</template>
<style lang="less" scoped>
</style>
3、安装和配置vuex
3.1、安装vuex
npm install vuex -S3.2、配置vuex
3.2.1、在src下创建store文件夹并在store文件夹下创建index.ts文件、getters.ts文件、modules文件夹
// index.ts 文件配置
import { createStore } from "vuex";
import type { App } from "vue";
import getters from "./getters";
// 获取modules文件夹中所有ts文件
const modulesFiles = import.meta.globEager('./modules/*.ts');
const modules: any = {};
interface Module {
default: object
}
/**
* 不需要import app from ./modules/app
* 它将自动从模块文件中要求所有的vuex模块
*/
Object.keys(modulesFiles).forEach(fileName => {
const name = fileName.replace(/^\.\/modules\/(.*)\.\w+$/, "$1");
modules[name] = (modulesFiles[fileName] as Module).default;
})
// 手动声明 state 类型
export interface State { }
const store = createStore<State>({
// 使用模块
modules,
getters,
});
export default store;// getters.ts 文件
const getters = {}
export default getters;3.2.2、在modules文件夹下创建users.ts(你可以创建自己需要的文件)
export interface State { }
const state = () => ({});
const mutations = {};
const actions = {}
export default {
namespaced: false,
state,
mutations,
actions,
}3.2.3、在main.ts文件中添加store引用
import { createApp } from 'vue'
/** --- 新增代码 start --- */
import store from './store'
/** --- 新增代码 end --- */
import router from './router'
import './style.css'
import App from './App.vue'
const app = createApp(App)
/** --- 新增代码 start --- */
app.use(store)
/** --- 新增代码 end --- */
app.use(router)
app.mount('#app')4、安装和配置axios
4.1、安装axios
npm install axios -S4.2、配置axios
4.2.1、配置封装axios，这边把封装的axios放在了src/utils/request 目录下，分别创下一下文件
- ? errorCode.ts，状态码对应提示
export default {
'401': '认证失败，无法访问系统资源',
'403': '当前操作没有权限',
'404': '访问资源不存在',
'default': '系统未知错误，请反馈给管理员'
}- axios.ts??axios封装
import axios from 'axios'
import { Modal, message, notification } from 'ant-design-vue'
import errorCode from '@/utils/request/errorCode'
// import { getToken } from '@/utils/auth' // 后续登录的token
// 是否显示重新登录
export const isRelogin = { show: false }
// axios.defaults.headers['Content-Type'] = 'application/json;charset=utf-8'
// 创建axios实例
const service = axios.create({
// axios中请求配置有baseURL选项，表示请求URL公共部分
baseURL: import.meta.env.VITE_BASE_URL,
// 超时
timeout: 10000
})
// request拦截器
service.interceptors.request.use(config => {
// 是否需要设置 token
// const isToken = (config.headers || {}).isToken === false
// if (getToken() && !isToken && config && config?.headers) {
// config.headers['Authorization'] = 'Bearer ' + getToken() // 让每个请求携带自定
// 义token 请根据实际情况自行修改
//}
return config
}, error => {
console.log(error)
Promise.reject(error)
})
// 响应拦截器
service.interceptors.response.use(res => {
// 未设置状态码则默认成功状态
const code = res.data.code
// 获取错误信息
const msg: string = errorCode[code as keyof typeof errorCode] || res.data.msg || errorCode['default']
// 二进制数据则直接返回
if (res.request.responseType === 'blob' || res.request.responseType === 'arraybuffer') {
return res.data
}
if (code === 401) {
if (!isRelogin.show) {
isRelogin.show = true
Modal.warning({
title: '系统提示',
content: '登录状态已过期，请重新登录',
onOk() {
isRelogin.show = false
location.href = '/login'
},
onCancel() {
isRelogin.show = false
location.href = '/login'
}
})
}
return Promise.reject('无效的会话，或者会话已过期，请重新登录。')
} else if (code === 500) {
message.error(msg)
return Promise.reject(new Error(msg))
} else if (code !== 200) {
notification.error({
message: msg
})
return Promise.reject('error')
} else {
return res.data
}
},
error => {
let msg = error.message
if (msg == 'Network Error') {
msg = '后端接口连接异常'
} else if (msg.includes('timeout')) {
msg = '系统接口请求超时'
} else if (msg.includes('Request failed with status code')) {
msg = '系统接口' + msg.substr(msg.length - 3) + '异常'
}
console.log(msg);
message.error(msg)
return Promise.reject(msg)
}
)
export default service
- index.ts? 封装对外请求暴露接口

4.3、创建api接口
4.3.1、创建api目录，（建议：分模块使用接口，这边案例使用的是login.ts）
import request from '@/utils/request'
import { LoginParams } from '@/constants/params/login' // 在公共目录下创建api参数对应的数据类型
// 登录方法
export function login(params: LoginParams) {
return request.post('/login', params, { isToken: false })
}constants/params 目录下的 login.ts
export interface LoginParams {
username: string,
password: string,
rememberMe: boolean,
code: string,
uuid: string
}
