- 写登录与注册的提交方法
- 结果
完成登录与注册的布局
前提是已安装node.js环境，npm,创建好spa项目
可以参考我的博文：https://blog.csdn.net/water_java/article/details/101353734
配置使用element-ui框架
打开package.josn文件，观察上线的依赖：
这是引入element-ui框架之前：
cmd命令窗口：
cd t237_spa1 #进入新建项目的根目录
npm install element-ui -S #安装element-ui模块
打开package.josn文件，观察上线的依赖：
这是引入element-ui框架之后：
改变main.js
在项目中src目录下找到main.js，并在指定位置添加三行代码（main.js是入口文件，所以在这里引入就行，页面就不用引入了）
1, import ElementUI from 'element-ui'2, import 'element-ui/lib/theme-chalk/index.css'
避免后期打包样式不同，要放在import App from './App';之前3 , Vue.use(ElementUI)
创建login.vue引入样式，调整格式
<template><div class="login-wrap"><el-form :model="ruleForm" label-width="100px" class="demo-ruleForm login-container"><h3 style="text-align:center ;">用户登录</h3><el-form-item label="用户名" prop="uname"><el-input type="uname" v-model="ruleForm.uname" autocomplete="off"></el-input></el-form-item><el-form-item label="密码" prop="pwd"><el-input type="pwd" v-model="ruleForm.pwd" autocomplete="off"></el-input></el-form-item><el-form-item><el-row><el-col :span="24"><div class="grid-content bg-purple-dark"><el-button type="primary" style="width: 100%;">提交</el-button></div></el-col></el-row><el-row><el-col :span="12"><div class="grid-content bg-purple"><el-link type="success">用户注册</el-link></div></el-col><el-col :span="12"><div class="grid-content bg-purple-light"><el-link type="success">忘记密码</el-link></div></el-col></el-row></el-form-item></el-form></div>
</template><script>export default {data() {return {ruleForm: {uname: 'zs',pwd: '123'}};}}

})测试结果
注册界面也差不多
设置登录与注册来回切换
使得登录与注册页面来回切换需在对应的文字连接设置事件
<el-link type="success" @click="doReg">用户注册</el-link>
<el-link type="success" @click="doLog">用户登录</el-link>
添加方法：
<script>export default {data() {return {ruleForm: {uname: 'zs',pwd: '123'}};},methods:{doSum(){//提交按钮},doReg(){this.$router.push({path:'/Reg'//注册//返回登录页面也是如此，就不展示代码了})}}}
</script>
后台交互
axios
安装axios:npm install axios -S
axios是vue2提倡使用的轻量版的ajax。它是基于promise的HTTP库。它会从浏览器中创建XMLHttpRequests，与Vue配合使用非常好。
GET提交axios.get('/user', {//注意数据是保存到json对象的params属性params: {ID: 12345}}).then(function (response) {console.log(response);}).catch(function (error) {console.log(error);});POST提交axios.post('/user', {//注意数据是直接保存到json对象firstName: 'Fred',lastName: 'Flintstone'}).then(function (response) {console.log(response);}).catch(function (error) {console.log(error);});注1：axios跨域问题会一直报错：“http://127.0.0.1:8848' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header”因为使用了前后端分离开发，跨域访问了，解决方案：需要配置tomcat允许跨域访问，tomcat跨域配置方法很多，但最简单的方式是自己写一个过滤器CorsFilter实现，添加一个响应头Access-Control-Allow-Origin即可httpResponse.addHeader("Access-Control-Allow-Origin", "*");//*表示任何域名httpResponse.addHeader("Access-Control-Allow-Origin", "http://localhost:80"); Access-Control-Allow-Origin:* #则允许所有域名的脚本访问该资源。Access-Control-Allow-Origin:https://www.fujieace.com #允许特定的域名访问 注2：axios.get提交没有问题，axios.post提交后台接收不到数据因为POST提交的参数的格式是Request Payload，这样后台取不到数据的(详情见资料“05 Vue中axios踩坑之路-POST传参 - RainSun - CSDN博客.mht”)，解决方案：使用qs.js库，将{a:'b',c:'d'}转换成'a=b&c=d'注3：为简化axios使用，还可以使用axios全局配置及拦截器，详情见资料“api/http.js”axios.defaults.baseURL = 'https://api.example.com';//axios.defaults.headers.common['Authorization'] = AUTH_TOKEN;//自定义请求头，添加认证令牌axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';注4：为方便开发，建议对请求地址进行封装，详情见资料“api/action.js”注5：^_^~~~~为进一步简化开发，将action.js的URL地址封装到axios.urls属性上
qs
安装qs:npm install qs -S
qs.js它是一个url参数转化的js库。用法就两个：
var obj = qs.parse(‘a=b&c=d’); //将URL解析成对象的形式：{a:‘b’,c:‘d’}
var str = qs.stringify(obj); //将对象 序列化成URL的形式，以&进行拼接：a=b&c=d’
vue-axios
安装vue-axios:npm install vue-axios -S
vue-axios是在axios基础上扩展的插件，在Vue.prototype原型上扩展了$http等属性，可以更加方便的使用axios
实现登录注册功能
别忘了启动eclipse的Tomcat
引入帮助文档
在sap项目的src目录下，引入api文件夹
api文件夹包括以下两个帮助js文档
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/T216_SSH', //服务器'SYSTEM_USER_DOLOGIN': '/vue/userAction_login.action', //用户登陆'SYSTEM_USER_DOREG': '/vue/userAction_reg.action', //用户注册'SYSTEM_MENU_TREE': '/vue/treeNodeAction.action', //左侧树形菜单加载'SYSTEM_ARTICLE_LIST': '/vue/articleAction_list.action', //文章列表'SYSTEM_ARTICLE_ADD': '/vue/articleAction_add.action', //文章新增'SYSTEM_ARTICLE_EDIT': '/vue/articleAction_edit.action', //文章修改'SYSTEM_ARTICLE_DEL': '/vue/articleAction_del.action', //文章删除'SYSTEM_USER_GETASYNCDATA': '/vue/userAction_getAsyncData.action', //vuex中的异步加载数据'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) {// var jwt = window.vm.$store.getters.getJwt;// config.headers['jwt'] = jwt;return config;
}, function(error) {return Promise.reject(error);
});// 响应拦截器
axios.interceptors.response.use(function(response) {// debugger;// var jwt = response.headers['jwt'];// if(jwt){// window.vm.$store.commit('setJwt',{jwt:jwt});// }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;修改main.js文件
当你安装完axios，qs，vue-axios后
修改main.js文件
#import axios from 'axios'#import qs from 'qs'import axios from '@/api/http' #vue项目对axios的全局配置 import VueAxios from 'vue-axios' Vue.use(VueAxios,axios)
写登录与注册的提交方法
//登录
methods:{doSum(){let url=this.axios.urls.SYSTEM_USER_DOLOGIN;//对应的key,找到对应的action//console.log(url);this.axios.post(url,this.ruleForm).then(function(response){console.log(response);}).catch(function(error){console.log(error);});},doReg(){this.$router.push({path:'/Reg'})}}
//注册结果
注册：
登录：
这篇关于Spa完成用户登录与注册的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
