Vue + Element UI + JSEncrypt实现简单登录页面

安装依赖

npm install jsencrypt --save

局部引入

import JSEncrypt from 'jsencrypt/bin/jsencrypt';

登录页面index.vue

<template><div class="loginbody"><div class="logindata"><div class="logintext"><h2>Welcome</h2></div><div class="formdata"><el-form ref="form" :model="form" :rules="rules"><el-form-item prop="username"><el-input v-model="form.username" clearable placeholder="请输入账号"></el-input></el-form-item><el-form-item prop="password"><el-input v-model="form.password" clearable placeholder="请输入密码" show-password></el-input></el-form-item></el-form></div><div class="tool"><el-checkbox v-model="checked" @change="remember">记住密码</el-checkbox></div><div class="butt"><el-button type="primary" @click.native.prevent="login('form')">登录</el-button></div></div></div></div>
</template><script>import JSEncrypt from 'jsencrypt/bin/jsencrypt';export default {data() {return {form: {username: "",password: "",},pbkey: "",checked: true,rules: {username: [{required: true,message: "请输入用户名",trigger: "blur"}],password: [{required: true,message: "请输入密码",trigger: "blur"}],},};},mounted() {// 是否记住密码if (localStorage.getItem("emisLoginInfo")) {this.form = JSON.parse(localStorage.getItem("emisLoginInfo"))this.checked = true;}},methods: {// 点击登录按钮login(form) {this.$refs[form].validate((valid) => {if (valid) {// 表单校验通过this.$api.getPublicKey(({data}) => {this.pbkey = data;this.doLogin();})} else {return false;}});},// 登录获取tokendoLogin() {let loginData = {userName: this.form.userName,passWord: this.encrypt(this.form.password)}this.$api.login(loginData, ({data}) => {localStorage.setItem("emisToken", data);this.$router.push({path: '/home'});})},// 加密encrypt(pwd) {const encrypt = new JSEncrypt();encrypt.setPublicKey(this.pbkey); //设置公钥return encrypt.encrypt(pwd);},// 解密 decrypt(pwd) {const encrypt = new JSEncrypt();encrypt.setPrivateKey(privateKey); //设置私钥return encrypt.decrypt(pwd);},// 记住密码remember(data) {this.checked = data;if (this.checked) {localStorage.setItem("emisLoginInfo", JSON.stringify(this.form))} else {localStorage.removeItem("emisLoginInfo")}},},};
</script><style scoped lang="scss">@import "index.scss";
</style>
