一、SPA项目登录注册布局
明确效果：登录注册界面效果：
1、在进行项目的布局时，首先要将需要的配置安装，依赖全部导入，在项目的cmd中将以下四行语句一行一行全部写入进去
npm install element-ui -S
npm install axios -S
npm install qs -S
npm install vue-axios -S
2、完成上述操作后，就可以使用elementUI来进行布局。将以下语句添加到src/main.js中
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
3、为了查看自己的配置是否配置成功，安装Element中组件进行检验，如果有效果就是安装配置成功。
Helloword.Vue：
<template>
<div class="hello">
<h1>{{ msg }}</h1>

</template>
<script>
export default {
name: 'HelloWorld',
data () {
return {
msg: 'Welcome to Your Vue.js App'
}
}
}
</script>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
h1, h2 {
font-weight: normal;
}
ul {
list-style-type: none;
padding: 0;
}
li {
display: inline-block;
margin: 0 10px;
}
a {
color: #42b983;
}
</style>
出现按钮效果就说明Element配置安装成功。
4、创建一个内部放组件的Vue，名叫Login.vue，到Element中找到表单的代码，写到Login.vue中，将组件提供出去。
Login.Vue:
<template>
<div id="app" class="login-wrap">
<h3 style="text-align: center;">用户登录</h3>
<el-form :model="ruleForm" status-icon ref="ruleForm" class="demo-ruleForm login-container">
<el-form-item label="账号" prop="uname">
<el-input type="text" v-model="ruleForm.uname" autocomplete="off"></el-input>
</el-form-item>
<el-form-item label="密码" prop="pwd">
<el-input type="password" 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 style="width: 100%;" type="primary" @click="submitForm('ruleForm')">提交</el-button>
</div>
</el-col>
</el-row>
<el-row>
<el-col :span="12">
<div class="grid-content bg-purple-dark">
<el-link type="success" @click="toReg">注册用户</el-link>
</div>
</el-col>
<el-col :span="12">
<div class="grid-content bg-purple-dark">
<el-link type="warning">忘记密码</el-link>
</div>
</el-col>
</el-row>
</el-form-item>
</el-form>
</div>
</template>
<script>
export default {
name: 'Login',
data() {
return {
ruleForm: {}
}
},
methods: {
toReg() {
this.$router.push({ //从一个界面跳转到另一个界面
path: '/Reg'
});
},
submitForm() {
let url = this.axios.urls.SYSTEM_USER_DOLOGIN;
this.axios.post(url, this.ruleForm).then((resp) => { //前后端交互的代码
console.log(resp);
if (resp.data.code == 1) {
this.$message({
message: resp.data.msg,
type: 'success'
});
} else {
this.$message({
message: resp.data.msg,
type: 'warning'
});
}
}).catch(function(error) {
console.log(error);
});
}
}
}
</script>

<el-form-item label="账号" prop="uname">
<el-input type="text" v-model="ruleForm.uname" autocomplete="off"></el-input>
</el-form-item>
<el-form-item label="密码" prop="pwd">
<el-input type="password" v-model="ruleForm.pwd" autocomplete="off"></el-input>
</el-form-item>
运行效果：
5、当我点击注册用户时，要跳转到用户注册界面。创建一个Reg.vue组件，将Login内容复制过去。要将组件名字改掉。
在Login.Vue中的注册用户写一个点击事件，到script中写一个跳转到Login界面的方法：
<script>
export default {
name: 'Login',
data() {
return {
ruleForm: {}
}
},
methods: {
toReg() {
this.$router.push({ //从一个界面跳转到另一个界面
path: '/Reg'
});
},
</script>this.$router.push({ //从一个界面跳转到另一个界面
path: '/Reg'
})
在reg.vue中跳转到Login.vue组件方法也是一样的。
二、SPA项目登录功能
前提：要到eclipse中导入maven项目，并且改变pom.xml中的mysql的版本，以及连接数据库db.properties文件中内容。
db.properties：
1、实现登录功能，就要实现前后端数据交互。
需求：当点击提交时，需要将数据从前端交互到后端，然后从后端访问数据库查看此用户的用户名和密码是否正确。
满足需求：在Login.Vue的提交的方法中，先实现前后端数据交互，在之后获取到访问到对应action的路径，之后判断，如果返回的数据是1，就表明用户登录成功，如果返回的数据是2，则登录失败。
Login.Vue：
submitForm() {
let url = this.axios.urls.SYSTEM_USER_DOLOGIN;
this.axios.post(url, this.ruleForm).then((resp) => { //前后端交互的代码
console.log(resp);
if (resp.data.code == 1) {
this.$message({
message: resp.data.msg,
type: 'success'
});
} else {
this.$message({
message: resp.data.msg,
type: 'warning'
});
}
}).catch(function(error) {
console.log(error);
});
其中url的写法：这就要从action.js和http.js中去查看
let url = this.axios.urls.SYSTEM_USER_DOLOGIN;
http.js
action.js:
2、eclipse中的登录action：
package com.zking.vue.web;
import java.util.HashMap;
import java.util.Map;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.opensymphony.xwork2.ModelDriven;
import com.zking.base.web.BaseAction;
import com.zking.vue.biz.UserBiz;
import com.zking.vue.entity.User;
import com.zking.vue.util.JsonData;
import com.zking.vue.util.JwtUtils;
import com.zking.vue.util.PageBean;
import com.zking.vue.util.ResponseUtil;
import com.zking.vue.util.StringUtils;
public class UserAction extends BaseAction implements ModelDriven<User>{
private UserBiz userBiz;
private User user = new User();
public UserBiz getUserBiz() {
return userBiz;
}
public void setUserBiz(UserBiz userBiz) {
this.userBiz = userBiz;
}
public String login() {
ObjectMapper om = new ObjectMapper();
JsonData jsonData = null;
try {
if(StringUtils.isBlank(user.getUname()) || StringUtils.isBlank(user.getPwd())) {
jsonData = new JsonData(0, "用户或者密码为空", user);
}else {
User u = this.userBiz.login(user);
// Map<String, Object> claims = new HashMap<String, Object>();
// claims.put("uname",user.getUname());
// claims.put("pwd", user.getPwd());
// String jwt = JwtUtils.createJwt(claims, JwtUtils.JWT_WEB_TTL);
// response.setHeader(JwtUtils.JWT_HEADER_KEY, jwt);
jsonData = new JsonData(1, "登录成功", u);
}
} catch (Exception e) {
e.printStackTrace();
jsonData = new JsonData(0, "用户或者密码错误", user);
}finally {
try {
ResponseUtil.write(response, om.writeValueAsString(jsonData));
} catch (Exception e) {
e.printStackTrace();
}
}
return null;
}
public String getAsyncData() {
ObjectMapper om = new ObjectMapper();
try {
Thread.sleep(6000);
ResponseUtil.write(response, om.writeValueAsString("http://www.javaxl.com"));
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
@Override
public User getModel() {
return user;
}
}

三、This的指针变量污染
1、为什么会出现This的指针变量污染？
当在html中使用了一个this时，this值就不会改变，即使是之后又用到了this，因为在axios中没有this这一作用域。
2、情景再现：
代码：
<script>
submitForm() {
let url = this.axios.urls.SYSTEM_USER_DOLOGIN;
this.axios.post(url, this.ruleForm).then(function(resp) { //前后端交互的代码
console.log(resp);
if (resp.data.code == 1) {
this.$message({
message: resp.data.msg,
type: 'success'
});
} else {
this.$message({
message: resp.data.msg,
type: 'warning'
});
}
}).catch(function(error) {
console.log(error);
});
</script>效果：
3、解决办法：
1、在外面定义一个变量，将this指针放入进入
2、使用箭头函数
1、在外面定义一个变量，将this指针放入进入
<script>
submitForm() {
let url = this.axios.urls.SYSTEM_USER_DOLOGIN;
let obj=this;
this.axios.post(url, this.ruleForm).then((resp) => { //前后端交互的代码
console.log(resp);
if (resp.data.code == 1) {
obj.$message({
message: resp.data.msg,
type: 'success'
});
} else {
this.$message({
message: resp.data.msg,
type: 'warning'
});
}
}).catch(function(error) {
console.log(error);
});
</script>2、使用箭头函数
四、Ajax跨域问题
1、出现ajax跨域问题有四种情况：
2、解决办法：
在eclipse中有一个cors.filter文件：这里面可以放任何域名，已经增删改查四个方法
五、Axious的get/post的区别
1、讲解Axious的get/post的区别也说是讲解http.js的作用：
一般的传数据到eclipse中有两种形式，第一种是数组的形式，另一种是字符串的形式。但是在eclipse中接受的值是字符串。
无论在src/main.js中用一下哪种依赖，都可以用
import axios from '@/api/http' //#vue项目对axios的全局配置
// import axios from 'axios' //#vue项目对axios的全局配置在Login.vue中用那种传值方式都可以
// let url = this.axios.urls.SYSTEM_USER_DOLOGIN;
let url = 'http://localhost:8080/T216_SSH/vue/userAction_login.action';
字符串：
对象：
但是接收对象时，eclipse中拿的值是空值，所以就会登录失败，
2、解决办法：
2.1在http.js中早就写好了，将对象转换成字符串的代码：
http.js:
//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;
};2.2在Login.vue中使用qs的stringify()方法就可以将对象转换成字符串：
以上两种解决方法都可以！
