【Vue.js】使用Element搭建登入注册界面axios中GET请求与POST请求跨域问题

一,ElementUI是什么?

              Element UI 是一个基于 Vue.js 的桌面端组件库,它提供了一套丰富的 UI 组件,用于构建用户界面。Element UI 的目标是提供简洁、易用、美观的组件,同时保持灵活性和可定制性

二,ElementUI的特点与功能(大致五点)

Element UI 的特点和功能包括:

丰富的组件:

           Element UI 提供了大量的常用组件,包括按钮、表单、表格、对话框、菜单等等。这些组件经过精心设计,具有统一的风格和交互体验,在构建用户界面时非常方便。

响应式布局:

        Element UI 的组件可以自动适应不同屏幕尺寸,支持响应式布局,使得应用程序在不同设备上都有良好的显示效果。

简洁易用:

     Element UI 的组件设计简洁,提供了丰富的配置选项,开发者可以通过参数的方式灵活地定制组件的外观和行为。
 

 主题定制:

     Element UI 提供了一套默认的主题样式,但也支持自定义主题。你可以根据项目的需求定制自己的主题样式,以使应用程序更符合项目的整体风格

国际化支持:

   Element UI 内置了多语言支持,可以方便地实现多语言应用程序

二,Element搭建登入注册前期准备

①搭建SPA项目   

没有搭建SPA项目---》》点击进入SPA项目搭建流程

②导入Element依赖

使用命令npm install element-ui -S,添加Element-UI模块

注意:要在你的SPA项目工作区间下使用cmd终端命令下载(如下)

下载完毕之后在你的SPA项目下的package.json文件中会看见下载所需要的Element依赖

三,Element实现登入注册界面 

第一步:在src目录下创建views目录(该目录用于存放vue组件)

第二步:在main.js中引入element-ui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

注意:要在import App from './App'这行代码前面添加下面三行代码

import Vue from 'vue'// 新添加1
import 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' 

Vue.jsx挂载Element代码(也是在main.js文件下添加即可):


Vue.use(ElementUI)   
Vue.config.productionTip = false

第三步:①创建用户登录组件Login.vue

<template><div class="login-wrap"><el-form class="login-container"><h1 class="title">用户登录</h1><el-form-item label=""><el-input type="text" v-model="username" placeholder="登录账号" autocomplete="off"></el-input></el-form-item><el-form-item label=""><el-input type="password" v-model="password" placeholder="登录密码" autocomplete="off"></el-input></el-form-item><el-form-item><el-button type="primary" style="width:100%;" @click="doSubmit()">提交</el-button></el-form-item><el-row style="text-align: center;margin-top:-10px"><el-link type="primary">忘记密码</el-link><el-link type="primary" @click="gotoRegister()">用户注册</el-link></el-row></el-form></div>
</template>

为了样式更加好看导入App.vue中的样式

App.vue样式:

<style> 
html,
body {width: 100%;height: 100%;box-sizing: border-box;padding: 0px;margin: 0px;
}
#app {font-family: "Avenir", Helvetica, Arial, sans-serif;-webkit-font-smoothing: antialiased;-moz-osx-font-smoothing: grayscale;color: #2c3e50;widows: 100%;height: 100%;
}
</style>

login.vue与Register.vue样式:

<style scoped>.login-wrap {box-sizing: border-box;width: 100%;height: 100%;padding-top: 10%;background-image: url(data:image/svg+xml;base64,<?xml version="1.0" encoding="UTF-8" standalone="no"?>

效果图:

index.js中设置绑定路由数据关系

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}]
})

效果:

四,数据交互

使用SSM项目构建Java后台,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。

4.1 了解axios与安装

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

安装语法:

npm i axios -S

默认为post请求

如果数据交互需要get请求要下载有关get请求的的依赖

get语法:

npm i qs -S

注意:要在你的SPA项目工作区间,启动cmd窗口,执行该行代码(如下)

4.2 axios之Post请求

1 在前端导入刚下载好的axios依赖

import axios from 'axios'

前端编写:

<script>
import axios from 'axios'
export default {name: 'Login',data () {return {username:'',password:''}} ,methods:{gotoRegister(){this.$router.push('/Register'); },doSubmit(){let url= 'localhost:8080/ssm/user/userLogin';let params = {username:this.username,password:this.password}axios.get(url,{params:params}).then(r=>{console.log(r);if(r.data.success){this.$message({message:r.data.msg,type:'success'});}else{this.$message.error(r.data.msg); }}).catch(e=>{})}}
}
</script>

在我们的后端项目中,有一个视图解析器来处理我们前端发过来的请求进行处理

userController:

package com.zking.ssm.controller;import com.zking.ssm.service.IUserService;
import com.zking.ssm.util.JsonResponseBody;
import com.zking.ssm.util.PageBean;
import com.zking.ssm.vo.UserVo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

在前端项目工作区间下,文件路径输入cmd,打开cmd窗口。

输入命令开启项目 : 

npm run dev

并且在后端启动maven项目,可以进行访问才可

// 		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;

需要在mian,js中配置:

main.js:

五,注册功能实现 

①自行创建一个注册页面

②定义接口、接口实现类

接口类:

int insertSelective(User record);

实现接口类:

    @Overridepublic int insertSelective(User record) {return userMapper.insertSelective(record);}

③ Controller层编写:

 @RequestMapping("/userRegister")@ResponseBodypublic JsonResponseBody<?> userRegister(UserVo userVo, HttpServletResponse response) {//状态新注册默认为0userVo.setStatus("0");//因为ID为String类型需要手动设置,当然可以根据自己的需要改为Int类型userVo.setId("9");int i = userService.insertSelective(userVo);if (i > 0) {return new JsonResponseBody<>("用户注册完成!快去登入吧!", true, 0, null);} else {return new JsonResponseBody<>("用户注册失败!重新输入。", false, 0, null);}}

五,跨域问题 

5.1 概念

      跨域问题(Cross-Origin Resource Sharing,CORS)指的是在浏览器端,由于安全策略限制,不同源(域/协议/端口)之间的网页(或者Ajax请求)无法直接进行交互或访问对方的资源。同源策略是浏览器的一种安全机制,用于保护用户信息和防止恶意攻击。

  同源策略要求网页只能与相同源的资源进行交互,源(Origin)由协议、域名和端口号组成。当源不一致时,浏览器会阻止跨域的请求。例如,一个网页在域A中运行,试图通过JavaScript向域B发送AJAX请求,此时就会触发跨域问题

5.2 解决跨域问题

web.xml:

  <!--CrosFilter跨域过滤器--><filter><filter-name>corsFilter</filter-name><filter-class>com.zking.ssm.util.CorsFilter2</filter-class></filter><filter-mapping><filter-name>corsFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>

跨域工具类:

CorsFilter2  过滤器

这段代码的作用是配置Tomcat服务器允许来自任何域名的跨域访问,并允许客户端发送包含指定请求头的请求,以及指定允许的请求方法

package com.zking.ssm.controller;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 CorsFilter2 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.setHeader("Access-Control-Allow-Origin", "*");// *,任何域名httpResponse.setHeader("Access-Control-Allow-Headers", "responseType,Origin, X-Requested-With, Content-Type, Accept");httpResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, DELETE");//允许客户端处理一个新的响应头jwt//httpResponse.setHeader("Access-Control-Expose-Headers", "jwt,Content-Disposition");filterChain.doFilter(servletRequest, servletResponse);}@Overridepublic void destroy() {}
}
