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静态页面的实现。

一. 登录，注册静态页面实现

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项目完成登录注册

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：

html 复制代码 
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' 

import App from './App'
import router from './router'

// 新添加3
Vue.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

html 复制代码 
<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>
				<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>

  },

      this.$router.push('/Register');

    }
  }
}
</script>

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

html 复制代码 
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

登录效果展示：

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。

html 复制代码 
<script>
  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 => {

        })



      }
    }
  }
</script>

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。

html 复制代码 
<script>
  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
        };


        // 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 => {

        })

      }
    }
  }
</script>

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
html 复制代码 
/**
 * 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': '/userAction.action', //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
html 复制代码 
/**
 * 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

html 复制代码 
import axios from '@/api/http'
import VueAxios from 'vue-axios'

Vue.use(VueAxios,axios)

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

java 复制代码 
  <!--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>
