一、spa项目完成登录注册布局
1、安装开发模块
在项目的根目录下cmd执行以下命令
npm install element-ui -S
npm install axios -S
npm install qs -S
npm install vue-axios -S
2、引入main.js配置
import Vue from 'vue'
import ElementUI from 'element-ui' // 新添加 1
import 'element-ui/lib/theme-chalk/index.css' // 新添加 2 ，避免后期打包样式不同，要放在import App from './App'; 之前
import App from './App'
import router from './router'
Vue.use(ElementUI) // 新添加 3
Vue.config.productionTip = false
3、登录注册页跳转
Login.vue

}
</style>router / index.js
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Login from '@/views/Login'
import Reg from '@/views/Reg'Vue.use(Router)export default new Router({routes: [{path: '/',name: 'Login',component: Login},{path: '/Login',name: 'Login',component: Login},{path: '/Reg',name: 'Reg',component: Reg}]
})
跳转效果：
二、vue数据交互实现登录功能
引入main.js配置
import axios from '@/api/http' #vue项目对axios的全局配置
import VueAxios from 'vue-axios'
Vue.use(VueAxios,axios)
Login.vue
<script>export default {name: 'Login',data() {return {ruleForm: {}}},methods: {submitForm(){//this.axios 找到的是/api/http.js文件//axios.urls = action 找到的是action.js//action.js是一个json对象 name就可以取到请求的值let url = this.axios.urls.SYSTEM_USER_DOLOGIN;// alert(url);this.axios.post(url,this.ruleForm).then(res =>{//代表成功 箭头函数 jdk8的语法console.log(res.data.result);if(res.data.code == 1){this.$message({message:res.data.msg,type:'success'});} else if(res.data.code == 0){this.$message.error(res.data.msg);}}).catch(function(){//代表失败});},Reg(){this.$router.push({path:'/Reg'})}}}
</script>
效果：
三、ajax 跨域问题
跨域产生的因素：协议、ip、端口、项目有任意一步发生改变，都会产生跨域
1.引入main.js配置
import axios from 'axios'2.跨域显现问题
3.解决方案
后端工具类里添加 CorsFilter.java
package com.javaxl.util;import java.io.IOException;import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletResponse;/*** 配置tomcat允许跨域访问* * @author Administrator**/
public class CorsFilter implements Filter {@Overridepublic void init(FilterConfig filterConfig) throws ServletException {}@Overridepublic void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)throws IOException, ServletException {HttpServletResponse httpResponse = (HttpServletResponse) servletResponse;// Access-Control-Allow-Origin就是我们需要设置的域名// Access-Control-Allow-Headers跨域允许包含的头。// Access-Control-Allow-Methods是允许的请求方式httpResponse.addHeader("Access-Control-Allow-Origin", "*");// *,任何域名httpResponse.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");httpResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, DELETE");filterChain.doFilter(servletRequest, servletResponse);}@Overridepublic void destroy() {}
}四、axios 的 get/post 的区别（ qs ）
axios、qs的作用
api/http.js
1.将原生大的json对象转换为字符串，通过拦截器转换
2.将本项目中的所有的接口地址，进行统一管理get/post的区别
this.form
