登录页面:
注册页面:
(1)引入element-plus组件库
引入组件库的方式有好多种,在这里我就在main.js全局引入了.
npm i element-plus -S
main.js中代码:
import { createApp } from "vue"; //element-plus import ElementPlus from "element-plus"; import "element-plus/dist/index.css"; import App from "./App.vue"; import router from "./router"; import axios from "axios"; import store from "./store"; //创建实例 const app = createApp(App); //全局应用配置 app.config.globalProperties.$axios = axios; app.use(ElementPlus).use(store).use(router).mount("#app");
引入之后自己可以用几个按钮测试一下是否引入成功.
(2)登录及注册页面
html部分
views/account/Login.vue
- {{ item.label }}
获取验证码 {{ current_menu === "login" ? "登录" : "注册" }}
js部分
css部分(使用了scss)
(3)封装一些公共方法及样式
新建styles文件夹,然后新建几个样式文件:
normalize.scss

elementui.scss(当时测试时用的)
.el-button-block{ display: block; width: 100%; }
新建main.scss(引入上方两个样式文件)
@import "./normalize.scss"; @import './elementui.scss'
vue.config.js配置一下样式文件
css: { // 是否使用css分离插件 ExtractTextPlugin extract: true, // 开启 CSS source maps? sourceMap: false, // css预设器配置项 loaderOptions: { scss: { additionalData: `@import "./src/styles/main.scss";`, }, }, // requireModuleExtension: true, },
登录中封装的校验方法
新建utils文件夹,
a.validate.js
// 校验邮箱 export function validate_email(value) { let regEmail = /^([a-zA-Z]|[0-9])(\w|\-)+@[a-zA-Z0-9]+\.([a-zA-Z]{2,4})$/; return regEmail.test(value); } // 校验密码 export function validate_password(value) { let regPassword = /^(?!\D+$)(?![^a-zA-Z]+$)\S{6,20}$/; return regPassword.test(value); } // 校验验证码 export function validate_code(value) { let regCode = /^[a-z0-9]{6}$/; return regCode.test(value); }
封装请求方法
npm i axios -S
记得先在main.js中引入axios
import axios from "axios";
utils中新建request.js
import axios from "axios"; //引入element-plus import { ElMessage } from "element-plus"; console.log("11", process.env.VUE_APP_API); //undefined?? //创建实例 const service = axios.create({ baseURL: "/devApi", //请求地址 timeout: 5000, //超时 }); //添加请求拦截器 service.interceptors.request.use( function (config) { //在发送请求之前做些什么 return config; }, function (error) { console.log(error.request); const errorData = JSON.parse(error.request.response); if (errorData.message) { //判断是否具有message属性 ElMessage({ message: errorData.message, type: "error", }); } //对请求错误做些什么 return Promise.reject(errorData); } ); //添加响 应拦截器 service.interceptors.response.use( function (response) { //对响应数据做些什么 console.log("响应数据", response); const data = response.data; if (data.resCode === 0) { return Promise.resolve(data); } else { ElMessage({ message: data.message, type: "error", }); return Promise.reject(data); } }, function (error) { //对响应错误做些什么 const errorData = JSON.parse(error.request.response); if (errorData.message) { //判断是否具有message属性 ElMessage({ message: errorData.message, type: "error", }); } return Promise.reject(errorData); } ); //暴露service export default service;
(4)配置环境变量
和项目根路径同级,新建几个文件:
.env.development
VUE_APP_API = '/devApi'
可以自定义,但是必须是VUE_APP_XXX的格式
.env.production
VUE_APP_API = '/production'
.env.test
VUE_APP_API = '/test'
配置完后记得在axios文件中打印一下,看下能输出自己配置的环境变量吗.
(5)配置代理(跨域)
基本大同小异,代理地址改成自己的就可以了.
devServer: { open: false, //编译完成是否自动打开网页 host: "0.0.0.0", //指定使用地址,默认是localhost,0.0.0.0代表可以被外界访问 port: 8080, proxy: { "/devApi": { target: "http://v3.web-jshtml.cn/api", //(必选)API服务器的地址 changeOrigin: true, //(必选) 是否允许跨域 ws: false, //(可选) 是否启用websockets secure: false, //(可选) 是否启用https接口 pathRewrite: { "^/devApi": "", //匹配开头为/devApi的字符串,并替换成空字符串 }, }, }, },
