先看一下最终要实现的效果:
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 -Smain.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

.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 ExtractTextPluginextract: 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websocketssecure: 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},},},},登录基本上是完成了,还有优化的点,比如说登录放在vuex中,
继续改造一下,把登录放在vuex中实现:
先看一下vuex的执行逻辑图:
store新建modules文件夹,新建app.js:
import { Login } from "@/api/account";const state = {count: 100,
};
const getters = {};
const mutations = {};
const actions = {loginAction(context, requestData) {return new Promise((resolve, reject) => {Login(requestData).then((response) => {resolve(response);}).catch((error) => {reject(error);});});},
};export default {namespaced: true,state,getters,mutations,actions,
};
登录页面改造:
import { useStore } from "vuex"; // storeconst store = useStore();注释掉之前的代码:
/** 登录 */// const login = () => {// const requestData = {// username: data.form.username,// password: sha1(data.form.password),// code: data.form.code,// };// data.submit_button_loading = true;// Login(requestData)// .then((response) => {// console.log("login", response);// data.submit_button_loading = false;// proxy.$message({// message: response.message,// type: "success",// });// reset();// })// .catch((error) => {// console.log("登录失败", error);// data.submit_button_loading = false;// });// };const login = () => {const requestData = {username: data.form.username,password: sha1(data.form.password),code: data.form.code,};data.submit_button_loading = true;store.dispatch("app/loginAction", requestData).then((response) => {proxy.$message({message: response.message,type: "success",});reset();}).catch((error) => {console.log("失败", error);});};好了,等有继续优化的地方我再继续完善.
(4)路由守卫
先来看一下总体的思路图:
在router文件下新建permit.js:
import router from "./index";
//cookie
import { getToken } from "@/utils/cookies";//全局路由守卫
router.beforeEach((to, from) => {// console.log("from", from);//token不存在if (!getToken()) {console.log("to", to);if (to.name !== "Login") {return {name: "Login",};}}
});//全局后置守卫
router.afterEach((to, from) => {console.log(to);console.log(from);
});
引入到main.js中:
//路由守卫
import "./router/permit";utils文件中新建cookies.js文件
先安装js-cookie:
npm i js-cookie -Scookies.js:
import Cookies from "js-cookie";//变量
const tokenKey = "tokenAdmin";
const usernameKey = "username";//获取token
export function getToken() {return Cookies.get(tokenKey);
}//写入token
export function setToken(value) {return Cookies.set(tokenKey, value);
}//删除token
export function removeToken() {return Cookies.remove(tokenKey);
}//写入 username
export function setUsername(value) {return Cookies.set(usernameKey, value);
}//获取 username
export function getUsername() {return Cookies.get(usernameKey);
}//删除 username
export function removeUsername() {return Cookies.remove(usernameKey);
}
vuex中改造一下:
store/app.js
import { Login, Logout } from "@a/account";
import {setToken,setUsername,getToken,getUsername,removeToken,removeUsername,
} from "@u/cookies";const state = {token: "" || getToken(),username: "" || getUsername(),collapse: JSON.parse(sessionStorage.getItem("collapse")) || false,
};
const getters = {};
const mutations = {SET_COLLAPSE(state) {state.collapse = !state.collapse;sessionStorage.setItem("collapse", JSON.stringify(state.collapse));},//设置tokenSET_TOKEN(state, value) {state.token = value;value && setToken(value); //当value存在时写入token},//设置用户名SET_USERNAME(state, value) {state.username = value;value && setUsername(value); //当value存在时写入token},
};
const actions = {//登录loginAction(context, requestData) {return new Promise((resolve, reject) => {Login(requestData).then((response) => {let data = response.data;context.commit(" SET_TOKEN", data.token);context.commit(" SET_USERNAME", data.username);resolve(response);}).catch((error) => {reject(error);});});},//退出logoutAction({ commit }) {return new Promise((resolve, reject) => {Logout().then((response) => {removeToken();removeUsername();commit(" SET_TOKEN", "");commit(" SET_USERNAME", "");resolve(response);}).catch((error) => {reject(error);});});},
};export default {namespaced: true,state,getters,mutations,actions,
};
主页有退出的话可以这么来触发:
<span class="logout" @click="handleLogout"><svg-icon iconName="logout" className="icon-logout"></svg-icon></span> //退出const handleLogout = () => {proxy.$confirm("确定退出管理后台", "提示", {confirmButtonText: "确定",cancelButtonText: "取消",type: "warning",}).then(() => {store.dispatch("app/logoutAction").then((res) => {proxy.$message({type: "success",message: res.message,});replace({name: "Login",});});}).catch(() => {// catch error});};记得引入和返回,不能忘记:
import { useStore } from "vuex";
import { ref, getCurrentInstance } from "vue";
import { useRouter } from "vue-router"; //获取实例上下文const { proxy } = getCurrentInstance();//引入routerconst { replace } = useRouter();const store = useStore(); return {handleLogout,};再来改造一下之前封装的axios方法:
import axios from "axios";
//引入element-plus
import { ElMessage } from "element-plus";
// console.log("11", process.env.VUE_APP_API); //undefined??
//cookies
+import { getToken, getUsername, removeToken, removeUsername } from "./cookies";
//引入路由
+import router from "@/router";//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+ if (getToken()) {config.headers["Token"] = getToken(); //携带token Token可以和后端约定}+ if (getUsername()) {config.headers["Username"] = getUsername();//Username可以和后端约定}console.log("config", config);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",});}//token失效自动退出+ if (errorData.resCode === 1010) {router.replace({name: "Login",});removeToken();removeUsername();}return Promise.reject(errorData);}
);//暴露service
export default service;
再来优化一下目录别名这块:
vue.config.js
configureWebpack: (config) => {config.resolve = {// 配置解析别名extensions: [".js", ".json", ".vue"], // 自动添加文件名后缀alias: {"@": path.resolve(__dirname, "./src"),"@u": path.resolve(__dirname, "./src/utils"),"@a": path.resolve(__dirname, "./src/api"),"@c": path.resolve(__dirname, "./src/components"),},};},改完记得重启项目,所以之前的代码就这样写了:
import { Login, Logout } from "@a/account";
import {setToken,setUsername,getToken,getUsername,removeToken,removeUsername,
} from "@u/cookies";
