前言

上一篇博客分享了SPA项目的构建，接下来，在SPA项目上接着完成登录注册的实现。

一. 登录，注册静态页面

1.1 ElementUI简介

Element-Ul是饿了么前端团队推出的一款基于Vue.js 2.0 的桌面端UI框架。

Element-Ul是一个ui库，它不依赖于vue。但是却是当前和vue配合做项目开发的一个比较好的ui框架。

ElementUI的优势包括：

1. 简单易用：ElementUI提供了一致的API和文档，使开发者能够快速上手并使用组件。它的设计风格简洁明了，易于理解和操作。

2. 高度可定制：ElementUI的组件具有丰富的配置选项，可以根据项目需求进行灵活的定制。开发者可以自定义样式、主题和功能，以满足不同的设计要求。

3. 响应式布局：ElementUI的组件支持响应式布局，可以适应不同的屏幕尺寸和设备类型。这使得应用程序在不同的平台上都能提供良好的用户体验。

4. 多语言支持：ElementUI提供了多语言支持，可以轻松地切换和本地化不同的语言。这对于开发多语言环境下的应用程序非常有用。

5. 活跃的社区支持：ElementUI拥有庞大的开发者社区，提供了丰富的资源和支持。开发者可以通过社区获取帮助、分享经验和参与贡献，使得开发过程更加顺利和高效。

1.2 基于SPA项目完成登录

1.2.1在SPA项目中添加elementui依赖

在创建的SPA项目根路径下cmd回车输入以下命令

npm install element-ui -S

成功后会在package.json中看到elementui依赖

​

1.2.2 在main.js中添加elementui模块

在项目中src目录下找到main.js ,并在指定位置添加三行代码：

import Vue from 'vue'// 新添加1import ElementUI from 'element-ui' // 新添加2，避免后期打包样式不同，要放在import App from './App';之前import 'element-ui/lib/theme-chalk/index.css' import App from './App'import router from './router'// 新添加3Vue.use(ElementUI) Vue.config.productionTip = false

重要的事情说三遍：在指定位置!!!在指定位置!!!在指定位置!!!~~~添加三行代码

1.2.3在src目录下创建views目录，用于存放vue组件

创建用户登录组件login.vue

在vue组件中，在style标签上添加scoped属性，以表示它的样式作用于当下的模块，很好的实现了样式私有化的目的。

1.2.4 配置路由

在router/index.js 中修改vue项目默认显示路由

import Vue from 'vue'import Router from 'vue-router'import HelloWorld from '@/components/HelloWorld'import Login from '@/views/Login'import Register from '@/views/Register'Vue.use(Router)export default new Router({routes: [{path: '/',name: 'Login',component: Login},{path: '/Register',name: 'Register',component: Register}]})

1.2.5 修改项目端口并启动

在 config/index.js 目录下修改vue项目运行端口

二. 数据交互

构建一个Java后台SSM项目，模拟提供一个用户登录的action地址，Vue通过请求指定的用户登录接口。

2.1.安装axios

axios是vue2提倡使用的轻量版的ajax。它是基于promise的HTTP库。它会从浏览器中创建XMLHttpRequests，与Vue配合使用非常好。

题外话：vue.js有著名的全家桶系列：vue-router，vuex， vue-resource，再加上构建工具vue-cli，就是一个完整的vue项目的核心构成。 其中vue-resource是Vue.js的一款插件，它可以通过XMLHttpRequest或JSONP发起请求并处理响应，但在vue更新到2.0之后，作者就宣告不再对vue-resource更新，而是推荐的axios

安装axios命令：

npm i axios -S

3.2.axios之get

使用axios的get请求方式，必须将请求参数保存到json对象的params属性中。

用户登录：

import axios from 'axios'import qs from 'qs'export default {name: 'Login',data() {return {username: '',password: ''}},methods: {gotoRegister() {this.$router.push('/Register');},doSubmit() {let url = this.axios.urls.SYSTEM_USER_DOLOGIN;let params = {username: this.username,password: this.password};// get请求axios.get(url, {params: params}).then(r => {console.log(r);if (r.data.success) {this.$message({message: r.data.msg,type: 'success'});}else{this.$message.error(r.data.msg);}}).catch(e => {})}}}

3.3.axios之post

使用axios的post请求方式，直接将请求参数保存到json对象中即可。

用户注册：

export default {name: 'Register',data () {return {id:'',realname:'',username:'',password:''}},methods:{gotoLogin(){this.$router.push('/');},doSubmit() {let url = this.axios.urls.SYSTEM_USER_DOREG;let params = {id : this.id,realname: this.realname,username: this.username,password: this.password};// post请求this.axios.post(url, params).then(r => {console.log(r);if (r.data.success) {this.$message({message: r.data.msg,type: 'success'});}else{this.$message.error(r.data.msg);}}).catch(e => {})}}}

axios.post提交后台接收不到数据的，因为POST提交的参数的格式是Request Payload

解决方案：使用qs.js库，将{a:’b’,c:’d’}转换成’a=b&c=d’

下载qs库 npm install qs -S

在Login.vue组件中导入qs import qs from ‘qs’

通过qs的stringify方法进行格式转换 let str=qs.stringify(params);

3.4.vue-axios

Axios是一个基于Promise 用于浏览器和 nodejs 的 HTTP 客户端，本质上也是对原生XHR的封装，只不过它是Promise的实现版本，符合最新的ES规范。

vue-axios是在axios基础上扩展的插件，在Vue.prototype原型上扩展了$http等属性，可以更加方便的使用axios。

通过vue-axios实现对axios的轻量封装：

第一步：下载安装vue-axios

npm i vue-axios -S

第二步：导入api模块，添加axios的全局配置

将api模块导入到SPA项目的src目录下，其中api模块包含了action.js（针对后台请求接口的封装定义）和http.js（针对axios的全局配置）两个文件。

• action.js

/** * 对后台请求的地址的封装，URL格式如下： * 模块名_实体名_操作 */export default {'SERVER': 'http://localhost:8080', //服务器'SYSTEM_USER_DOLOGIN': '/user/userLogin', //登陆'SYSTEM_USER_DOREG': '/user/userRegister', //注册'getFullPath': k => { //获得请求的完整地址，用于mockjs测试时使用return this.SERVER + this[k];}}

• http.js

/** * vue项目对axios的全局配置 */import axios from 'axios'import qs from 'qs'//引入action模块，并添加至axios的类属性urls上import action from '@/api/action'axios.urls = action// axios默认配置axios.defaults.timeout = 10000; // 超时时间// axios.defaults.baseURL = 'http://localhost:8080/j2ee15'; // 默认地址axios.defaults.baseURL = action.SERVER;//整理数据// 只适用于 POST,PUT,PATCH，transformRequest` 允许在向服务器发送前，修改请求数据axios.defaults.transformRequest = function(data) {data = qs.stringify(data);return data;};// 请求拦截器axios.interceptors.request.use(function(config) {return config;}, function(error) {return Promise.reject(error);});// 响应拦截器axios.interceptors.response.use(function(response) {return response;}, function(error) {return Promise.reject(error);});// // 路由请求拦截// // http request 拦截器// axios.interceptors.request.use(// config => {// //config.data = JSON.stringify(config.data);// //config.headers['Content-Type'] = 'application/json;charset=UTF-8';// //config.headers['Token'] = 'abcxyz';// //判断是否存在ticket，如果存在的话，则每个http header都加上ticket// // if (cookie.get("token")) {// // //用户每次操作，都将cookie设置成2小时// // cookie.set("token", cookie.get("token"), 1 / 12)// // cookie.set("name", cookie.get("name"), 1 / 12)// // config.headers.token = cookie.get("token");// // config.headers.name = cookie.get("name");// // }// return config;// },// error => {// return Promise.reject(error.response);// });// // 路由响应拦截// // http response 拦截器// axios.interceptors.response.use(// response => {// if (response.data.resultCode == "404") {// console.log("response.data.resultCode是404")// // 返回 错误代码-1 清除ticket信息并跳转到登录页面// //cookie.del("ticket")// //window.location.href='http://login.com'// return// } else {// return response;// }// },// error => {// return Promise.reject(error.response) // 返回接口返回的错误信息// });export default axios;

第三步：修改main.js配置vue-axios

在main.js文件中引入api模块和vue-axios模块

import axios from '@/api/http'import VueAxios from 'vue-axios'Vue.use(VueAxios,axios)

3.5 登录注册后端代码

service层

List<Map> queryUserPager(UserVo userVo, PageBean pageBean);int insertSelective(UserVo userVo);

@Overridepublic List<Map> queryUserPager(UserVo userVo, PageBean pageBean) {return userMapper.queryUserPager(userVo);}@Overridepublic int insertSelective(UserVo userVo) {return userMapper.insertSelective(userVo);}

controller层

@RequestMapping("/userLogin")@ResponseBodypublic JsonResponseBody json=new HashMap();//json.put("username", userVo.getUsername());//生成JWT，并设置到response响应头中//String jwt=JwtUtils.createJwt(json, JwtUtils.JWT_WEB_TTL);//response.setHeader(JwtUtils.JWT_HEADER_KEY, jwt);return new JsonResponseBody("用户登陆成功！",true,0,null);}else{return new JsonResponseBody("用户名或密码错误！",false,0,null);}}@RequestMapping("/userRegister")@ResponseBodypublic JsonResponseBody userRegistered(UserVo userVo, HttpServletRequest request){int insertSelective = userService.insertSelective(userVo);if(insertSelective>0){return new JsonResponseBody("用户注册成功！",true,0,null);}else{return new JsonResponseBody("注册失败，请稍后！",false,0,null);}}

3.6 效果展示

三. 跨域问题

3.1 什么是跨域

在浏览器同源策略限制下，向不同源（不同协议、不同域名或者不同端口）发送XHR请求，浏览器认为该请求不受信任，禁止请求，具体表现为请求后不正常响应。

3.2 怎么解决跨域问题

针对于本篇SPA项目，在后台代码添加一个跨域过滤器

corsFiltercom.zking.ssm.util.CorsFilter2corsFilter/*
