    一、前置准备工作

    1.1 导入后端代码

    我们找一个后台有增删改查的简单项目，导入我们的编码器，Leaf这里用的是eclipse；

    然后我们还需要把两个js工具包组成的一个文件夹导入前端SPA项目中，用以与后台代码相关联，调用后台接口。

    这里把两个js文件放到这里，需要的朋友把它们放到同一文件夹【api】中，然后再导入前端项目中：

    action.js

    1. /**
    2.  * 对后台请求的地址的封装，URL格式如下：
    3.  * 模块名_实体名_操作
    4.  */
    5. export default {
    6. 	'SERVER': 'http://localhost:8080/T216_SSH/', //服务器
    7. 	'SYSTEM_USER_DOLOGIN': '/vue/userAction_login.action', //用户登陆
    8. 	'SYSTEM_USER_DOREG': '/vue/userAction_reg.action', //用户注册
    9. 	'SYSTEM_MENU_TREE': '/vue/treeNodeAction.action', //左侧树形菜单加载
    10. 	'SYSTEM_ARTICLE_LIST': '/vue/articleAction_list.action', //文章列表
    11. 	'SYSTEM_ARTICLE_ADD': '/vue/articleAction_add.action', //文章新增
    12. 	'SYSTEM_ARTICLE_EDIT': '/vue/articleAction_edit.action', //文章修改
    13. 	'SYSTEM_ARTICLE_DEL': '/vue/articleAction_del.action', //文章删除
    14. 	'SYSTEM_USER_GETASYNCDATA': '/vue/userAction_getAsyncData.action', //vuex中的异步加载数据
    15. 	'getFullPath': k => { //获得请求的完整地址，用于mockjs测试时使用
    16. 		return this.SERVER + this[k];
    17. 	}
    18. }

    http.js

    1. /**
    2.  * vue项目对axios的全局配置
    3.  */
    4. import axios from 'axios'
    5. import qs from 'qs'
    6.  
    7. //引入action模块，并添加至axios的类属性urls上
    8. import action from '@/api/action'
    9. axios.urls = action
    10.  
    11. // axios默认配置
    12. axios.defaults.timeout = 10000; // 超时时间
    13. // axios.defaults.baseURL = 'http://localhost:8080/j2ee15'; // 默认地址
    14. axios.defaults.baseURL = action.SERVER;
    15.  
    16. //整理数据
    17. // 只适用于 POST,PUT,PATCH，transformRequest` 允许在向服务器发送前，修改请求数据
    18. axios.defaults.transformRequest = function(data) {
    19. 	data = qs.stringify(data);
    20. 	return data;
    21. };
    22.  
    23.  
    24. // 请求拦截器
    25. axios.interceptors.request.use(function(config) {
    26. 	// var jwt = window.vm.$store.getters.getJwt;
    27. 	// config.headers['jwt'] = jwt;
    28. 	return config;
    29. }, function(error) {
    30. 	return Promise.reject(error);
    31. });
    32.  
    33. // 响应拦截器
    34. axios.interceptors.response.use(function(response) {
    35. 	// debugger;
    36. 	// var jwt = response.headers['jwt'];
    37. 	// if(jwt){
    38. 	// 	window.vm.$store.commit('setJwt',{jwt:jwt});
    39. 	// }
    40. 	return response;
    41. }, function(error) {
    42. 	return Promise.reject(error);
    43. });
    44.  
    45. // // 路由请求拦截
    46. // // http request 拦截器
    47. // axios.interceptors.request.use(
    48. // 	config => {
    49. // 		//config.data = JSON.stringify(config.data);  
    50. // 		//config.headers['Content-Type'] = 'application/json;charset=UTF-8';
    51. // 		//config.headers['Token'] = 'abcxyz';
    52. // 		//判断是否存在ticket，如果存在的话，则每个http header都加上ticket
    53. // 		// if (cookie.get("token")) {
    54. // 		// 	//用户每次操作，都将cookie设置成2小时
    55. // 		// 	cookie.set("token", cookie.get("token"), 1 / 12)
    56. // 		// 	cookie.set("name", cookie.get("name"), 1 / 12)
    57. // 		// 	config.headers.token = cookie.get("token");
    58. // 		// 	config.headers.name = cookie.get("name");
    59. // 		// }
    60. // 		return config;
    61. // 	},
    62. // 	error => {
    63. // 		return Promise.reject(error.response);
    64. // 	});
    65.  
    66. // // 路由响应拦截
    67. // // http response 拦截器
    68. // axios.interceptors.response.use(
    69. // 	response => {
    70. // 		if (response.data.resultCode == "404") {
    71. // 			console.log("response.data.resultCode是404")
    72. // 			// 返回 错误代码-1 清除ticket信息并跳转到登录页面
    73. // 			//      cookie.del("ticket")
    74. // 			//      window.location.href='http://login.com'
    75. // 			return
    76. // 		} else {
    77. // 			return response;
    78. // 		}
    79. // 	},
    80. // 	error => {
    81. // 		return Promise.reject(error.response) // 返回接口返回的错误信息
    82. // 	});
    83.  
    84.  
    85.  
    86. export default axios;

    然后我们这个时候一定要对我们找来的项目进行测试，确认与你本机数据库连接没有问题后再进行后面的开发。

    1.2 下载js依赖

    我们需要分别下载四个依赖：

    axios：前端新后台发送请求

    qs：解决发送post请求代码冗余的问题

    ElementUI：快速布局

    vue-axios：将axios依赖整合到vue中

    而下载这个的话就必须去到我们前端项目的根目录下运行下载指令，进行下载！

    下载指令：

    npm install element-ui -S

    npm install axios -S

    npm install qs -S  

    npm install vue-axios -S

    第一个指令

    第二个指令

    第三个指令

    第四个指令

    当我们成功下载好四个依赖后，就可以在前端项目的package.json文件的dependencies中看到多出来的四个依赖：

    到这一步后，就代表，我们的前置准备工作完成啦！

    二、登录页面的排版

    2.1 导入Element-UI的依赖

    我们需要用到ElementUI来完成登录页面的制作，所以就需要先引入它的依赖到main.js中；

    main.js

    1. // The Vue build version to load with the `import` command
    2. // (runtime-only or standalone) has been set in webpack.base.conf with an alias.
    3. import Vue from 'vue'
    4. import ElementUI from 'element-ui' // 新添加 1
    5. // 避免后期打包样式不同，所以放在import App from './App'; 之前
    6. import 'element-ui/lib/theme-chalk/index.css' // 新添加 2
    7. import App from './App'
    8. import router from './router'
    9.  
    10. Vue.use(ElementUI)   // 新添加 3
    11.  
    12. Vue.config.productionTip = false
    13.  
    14. /* eslint-disable no-new */
    15. new Vue({
    16.   el: '#app',
    17.   router,
    18.   components: { App },
    19.   template: ''
    20. })

    然后我们把上篇文章写的那些组件、触发事件、组件和路由的关系定义全部删除，让它们回到最初的模样，准备测试今天内容。

    测试ElementUI是否能正常使用：

    ① 我们去到ElementUI的官网，随便找一些组件按钮代码，粘贴到App.vue文件中；

    官网：Element - The world's most popular Vue UI framework

    ② 在项目根目录运行npm run dev

    欧克，我们测试ElementUI组件能用，没有问题。

    2.2 编写登录页面展示内容

    我们看看项目src目录下文件夹的一些参考定义：

    assets：静态资源

    components：放自定义组件

    router：路由对应关系

    views：展示内容

    而登录的业务代码就属于views里面；

    我们在views中建立一个vue文件：Login.vue

    并且在ElementUI官网中粘贴一份表单代码过来。

    参考代码：Login.vue

    1. <template>
    2.   <div class="login-wrap">
    3.     <el-form :model="ruleForm" status-icon label-width="100px" class="demo-ruleForm login-container">
    4.       <el-row>
    5.         <el-col :span="24">
    6.           <div style="text-align: center;" class="grid-content bg-purple-dark">
    7.             <h3>用户登录h3>
    8.           div>
    9.         el-col>
    10.       el-row>
    11.       <el-form-item label="用户名" prop="uname">
    12.         <el-input v-model.number="ruleForm.uname">el-input>
    13.       el-form-item>
    14.       <el-form-item label="密码" prop="pwd">
    15.         <el-input type="password" v-model="ruleForm.pwd" autocomplete="off">el-input>
    16.       el-form-item>
    17.       <el-form-item>
    18.         <el-row>
    19.           <el-col :span="24">
    20.             <div style="text-align: center;" class="grid-content bg-purple-dark">
    21.               <el-button style="width: 100%;" type="primary" @click="submitForm">提交el-button>
    22.             div>
    23.           el-col>
    24.         el-row>
    25.       el-form-item>
    26.       <el-form-item>
    27.         <el-row>
    28.           <el-col :span="12">
    29.             <div style="text-align: center;" class="grid-content bg-purple-dark">
    30.               <el-link type="success" @click="">用户注册el-link>
    31.             div>
    32.           el-col>
    33.           <el-col :span="12">
    34.             <div style="text-align: center;" class="grid-content bg-purple-dark">
    35.               <el-link type="warning" @click="">忘记密码el-link>
    36.             div>
    37.           el-col>
    38.         el-row>
    39.       el-form-item>
    40.     el-form>
    41.   div>
    42. template>
    43.  
    44. <script>
    45.   export default {
    46.     name: 'Login',
    47.     data() {
    48.       return {
    49.         ruleForm: {}
    50.       }
    51.     },
    52.     methods: {
    53.       submitForm() {
    54.  
    55.       },
    56.       resetForm() {
    57.  
    58.       }
    59.     }
    60.   }
    61. script>
    62.  
    63. <style>
    64.  
    65. style>

    接下来就一起改一下我们的样式，让这个登录页面好看一些嘿嘿嘿。

    ① 修改App.vue中的style；

    ② 修改Login.vue中的style；

    App.vue

    1. <style>
    2. html,
    3. body {
    4.     width: 100%;
    5.     height: 100%;
    6.     box-sizing: border-box;
    7.     padding: 0px;
    8.     margin: 0px;
    9. }
    10. #app {
    11.     font-family: "Avenir", Helvetica, Arial, sans-serif;
    12.     -webkit-font-smoothing: antialiased;
    13.     -moz-osx-font-smoothing: grayscale;
    14.     color: #2c3e50;
    15.     widows: 100%;
    16.     height: 100%;
    17. }
    18. style>

    Login.vue

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

    我们一起来看看运行效果图：

    三、Vue数据交互 - 实现登录

    3.1 添加点击事件

    我们给Login.vue中的用户注册添加一个点击事件，定义方法；

    点击事件：

    1. <div style="text-align: center;" class="grid-content bg-purple-dark">
    2.   <el-link type="success" @click="toReg">用户注册el-link>
    3. div>

    跳转注册的方法：

    1. toReg() {
    2.     this.$router.push({
    3.       path: '/Reg'
    4.     });
    5. }

    然后我们再复制一份登录页面，修改一下，改成注册页面，并且一样的写好跳转到登录页面的方法；

    Reg.vue

    1. <template>
    2.   <div class="login-wrap">
    3.     <el-form :model="ruleForm" status-icon label-width="100px" class="demo-ruleForm login-container">
    4.       <el-row>
    5.         <el-col :span="24">
    6.           <div style="text-align: center;" class="grid-content bg-purple-dark">

    9.         el-col>
    10.       el-row>
    11.       <el-form-item label="用户名" prop="uname">

    14.       <el-form-item label="密码" prop="pwd">
    15.         <el-input type="password" v-model="ruleForm.pwd" autocomplete="off">el-input>
    16.       el-form-item>
    17.       <el-form-item>
    18.         <el-row>

    3.2 导入axios的依赖

    axios相当于jQuery中的ajax

    作用：使用获取后台数据，做局部刷新

    1. import axios from '@/api/http'  #vue项目对axios的全局配置      
    2. import VueAxios from 'vue-axios'
    3.  
    4. Vue.use(VueAxios,axios);

    编写登录的提交方法：

    1. submitForm() {
    2.     //this.axios找到的是/api/http.js文件
    3.     //http又配置了axios.urls = action ---> this.axios.urls找到了action.js
    4.     //action.js是一个JSON对象，那么就可以取到请求的路径值
    5.     let url = this.axios.urls.SYSTEM_USER_DOLOGIN;
    6.     //alert(url);
    7.     //url就是请求后台的某一个接口
    8.     this.axios.post(url,this.ruleForm)
    9.         .then(function(resp){//成功回调函数
    10.           console.log(resp);
    11.         }).catch(function(){//失败回调函数
    12.         });
    13. },

    然后我们测试一下：

    不输入密码：

    输入错误信息：

     

    输入正确信息：

    最后我们总结一下：

    语法：

    1. this.axios.post(请求地址，参数)
    2.  
    3. .then(function(resp) {})
    4.  
    5. .catch(function(error) {})

    四、this指针污染

    4.1 箭头函数

    我们发现我们把ElementUI中的消息提示语句，写到axios.post提交的方法内是没有效果的，原因就是因为这个post提交方法的内部已经不是vue实例，而是http.js，这就是this的指针污染。

    而现在我们的解决方法就是利用jdk8的箭头函数语法。

    1. //这个this指的是vue实例
    2. //let obj = this;
    3. this.axios.post(url,this.ruleForm)
    4. .then(resp => {//成功回调函数 箭头函数 jdk8语法
    5.   //console.log(resp);
    6.   if(resp.data.code == 1){
    7.     this.$message({
    8.       message: '恭喜你，登录成功！！！',
    9.       type: 'success'
    10.     });
    11.   }
    12.   else if(resp.data.code == 0){
    13.     this.$message.error('密码或用户名输入有误，登录失败！！！');
    14.   }
    15. }).catch(function(){//失败回调函数
    16. });

    然后我们来测试一下；

    登录成功

    登录失败

    五、CORS跨域

    5.1 CORS跨域体现

    5.2 跨域产生的因素

    我们先来分析一下我们访问网址是由哪些元素组成的；

    例如：

    http://localhost:8080/Leaf_0909/ --->

    协议+ip+端口号+项目

    跨域产生原因：只要请求地址中的元素有任意一处发生改变，就会产生跨域的问题。

    5.3 解决跨域问题办法

    要解决跨域的问题，我们就可以在后台项目的web.xml中添加一个过滤器就ok了；

    过滤器代码：

    2. <filter>
    3. <filter-name>corsFilterfilter-name>
    4.     <filter-class>com.zking.vue.util.CorsFilterfilter-class>
    5. filter>
    6. <filter-mapping>
    7. <filter-name>corsFilterfilter-name>
    8.     <url-pattern>/*url-pattern>
    9. filter-mapping>

    六、原始axios的使用&get - post的区别

    6.1 原始axios请求的使用

    更换在main.js文件中导入的依赖，注释原本导入的vue项目对axios的全局配置；

    1. // import axios from '@/api/http'  //vue项目对axios的全局配置
    2. import axios from 'axios'

    改变导入依赖后，一定要重启项目：

    然后我们测试一下登录：

    这个时候我们只用了原始的axios提交，没有用到工具包，所以返回的是一个对象，不能验证。

    所以我们就需要用到工具包：

    我们在Login.vue中单独使用一下上篇文章下载的“qs”，在这个页面中导入qs依赖；

    import qs from 'qs'

    然后在登录的方法上使用：

    this.axios.post(url,qs.stringify(this.ruleForm))

    并且写死请求路径值：

    let url = "http://localhost:8080/T216_SSH/vue/treeNodeAction";

    然后我们再次测试：

    因此，我们可以发现前面我们用的工具包http.js、action.js的几个作用：

    1、将原生的json对象转成字符串，通过拦截器转换；

    2、将本项目中俄所有接口地址，进行统一管理；

    6.2 get - post的区别

    这个Leaf就直接放上代码，看代码参考咯；

    get请求

    1. let url = this.axios.urls.SYSTEM_USER_DOLOGIN;
    2. this.axios.post(url, this.ruleForm).then(function(response) {
    3. console.log(response);
    4. }).catch(function(error) {
    5. console.log(error);
    6. });

    post请求

    1. let url = this.axios.urls.SYSTEM_USER_DOLOGIN;
    2. this.axios.get(url, { //注意数据是保存到json对象的params属性
    3. params: this.ruleForm
    4. }).then(function(response) {
    5. console.log(response);
    6. }).catch(function(error) {
    7. console.log(error);
    8. });
