vue搭建项目、创建登录页面和后台交互之引入axios

1. 搭建项目

1.1 使用vue-cli创建项目

1.2 通过npm安装element-ui

1.3 导入组件

2.4 在Login组件中将提交按键调整为100%宽度

2.5 运行效果

3. 后台交互

3.1 引入axios

3.2 axios/qs/vue-axios安装与使用

1. 搭建项目

工程方式搭建项目，请将测试需要用的后台web服务程序事先准备好。

具体搭建项目可以查看我上一篇文章

1.1 使用vue-cli创建项目

在命令行，到自己的vue工程存放的目录，运行一下命令，前提是vue-cli先安装好。

vue init webpack vuepro

1.2 通过npm安装element-ui

npm install element-ui -S

如果安装成功就会有此配置

1.3 导入组件

打开 src目录下的main.js，该文件是项目的入口文件，所以在这里导入，其他组件均可使用，不用再导入。


import Vue from 'vue'
 
//新添
import ElementUI from 'element-ui' 
 
//新增
import 'element-ui/lib/theme-chalk/index.css'
 
//新增
Vue.use(ElementUI) 
。。。

此‘element-ui’就是图中的这个名称

2 创建登录页面

2.1 创建登录组件

1）新建views目录，在目录上右击，选择新建vue（简单模块）创建Login


<template>
</template>
 
<script>
</script>
 
<style>
</style>

2）在element-ui组件，在form组件中找到与登录页面类似的组件，拷贝代码到刚新建的Login组件中，修改为自己需要的登录页面，页面包含：账户，密码，提交按钮


<template>
    <div>
        <el-form >
            <el-form-item label="账户" >
              <el-input type="password" v-model="userName" autocomplete="off"></el-input>
            </el-form-item>
            <el-form-item label="密码" >
              <el-input type="password" v-model="passWord" autocomplete="off"></el-input>
            </el-form-item>
            <el-form-item>
              <el-button type="primary" @click="submitForm('ruleForm')">提交</el-button>
            </el-form-item>
         </el-form>
    </div>
</template>
 
<script>
  export default {
    name: 'Login',
    data: function() {
      return {
         userName: null,
         passWord: null,
      }
    },
    methods: {
      submitForm: function() {
          console.log("fdfdd");
      }
    }
  }
</script>
 
<style>
</style>

2.2 引入css（css.txt）

按照css.txt中的说明进行引入，用于控制样式，加入样式

base64编码：
基于64个可打印字符来表示二进制数据，用于传输8Bit字节代码，可用于在HTTP环境下传递较长的标识信息。采用Base64编码具有不可读性，需要解码后才能阅读。

2.3 配置路由

router/index.js


import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
 
//首先导入组件
import Login from '@/views/Login'
 
Vue.use(Router)
 
export default new Router({
  routes: [
    {
      //配置路由，根路径访问Login组件
      path: '/',
      name: 'Login',
      component: Login
    }
  ]
})

2.4 在Login组件中将提交按键调整为100%宽度

<el-button type="primary" @click="submitForm('ruleForm')" style="width:100%">提交</el-button>

2.5 运行效果

在项目目录，运行一下命令，启动服务：

npm run dev

界面效果：

3. 后台交互

3.1 引入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。
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

安装成功后可以在此配置中查看

3.2 axios/qs/vue-axios安装与使用

注：
qs.js它是一个url参数转化的js库。用法就两个：


var obj = qs.parse('a=b&c=d');  //将URL解析成对象的形式：{a:'b',c:'d'}
var str = qs.stringify(obj);    //将对象 序列化成URL的形式，以&进行拼接：a=b&c=d'

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

3.2.1 安装axios

npm install axios -S

2）在Login组件中导入axios


  import axios from 'axios'
  export default {
  ......

3.2.2 发送get请求：

在提交按钮的监听函数中加入发送get请求的代码：


//请求url，需要保证服务可用
let url = 'http://localhost:8080/webserver/userMsg/userAction!login.action';
//注意数据是保存到json对象的params属性
axios.get(url, {
  params: {
    userNo: this.userNo,
    userPwd: this.userPwd
  }
}).then(function(response) {
  console.log(response);
}).catch(function(error) {
  console.log(error);
});

请注意下面图上的错误信息，请求发生了跨域错误问题：

跨域请求问题：
因为我们采用的是前后端分离的方式进行开发，前端和后端分别泡在不同的服务器上，基于安全性考虑，浏览器有同源策略，所以出现了跨域问题。
同源策略[same origin policy]是浏览器的一个安全功能，不同源的客户端脚本在没有明确授权的情况下，不能读写对方资源。同源策略是浏览器安全的基石。

4）跨域问题的处理
在filter中处理跨域问题，关键代码：


// 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", "Origin, X-Requested-With, Content-Type, Accept");
httpResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, DELETE");
filterChain.doFilter(servletRequest, servletResponse);

在课件资料中提供了CorsFilter，配置到web.xml中，对所以请求进行拦截处理，可解决跨域问题。注意：请配置在struts中央控制器之前

3.2.3 发送post请求：


//注意数据是直接保存到json对象
axios.post(url, {
    userNo: 'admin',
    userPwd: '123'
}).then(function(response) {
    console.log(response);
}).catch(function(error) {
    console.log(error);
});

输入的测试账号和密码均正确，使用get发送请求获取的响应为“密码正确”，但post方式发送的请求获取的响应为“密码不正确”！

预检请求代码

原因：上图所示，因为使用app/json的方式用post，那么会提交两次

第一次是有值

第二次是空值

原因分析：通过观察控制台可以发现，post发送请求时，请求参数是以json格式通过request payload进行传送的，的struts的并没有处理这种方式传递的参数（起码是我们使用的struts版本），所以传递到服务器的参数并没有得到有效的解析。

3.2.4解决方法一

加个@RequestBody

3.2.5运行结果

但是还是提交了两次，第一次还是预检请求，第二次i才是真正的提交

3.2.6解决方法二

导入qs

写一个params和paramStr

只有提交一次了，但是不是json的格式提交了，现在是表单的方式提交了（也就是qs库改的）

也就是这里，使用qs将json转换成了表单的方式提交了

问题处理：
第一种方式：在服务端编码实现request payload参数解析。在BaseAction中加入一个方法，该方法从request payload中获取json数据，并转化为指定的类。


public Object getRequestBody(Class clazz) {   
 
        BufferedReader br;
        HttpServletRequest request = ServletActionContext.getRequest();
 
        try {
            br = request.getReader();
            String str, aStr = "";
            while((str = br.readLine()) != null){
                aStr += str;
            }
 
            System.out.println(aStr);
            Object obj = JSONObject.parseObject(aStr, clazz);
 
            return obj;
        } catch (IOException e) {
           throw new RuntimeException("获取请求参数异常: " + e);
        }
    }

获取参数时调用该方法获取

User user = (User)this.getRequestBody(User.class);

第二种方式：使用qs.js库，将{a:'b',c:'d'}转换成'a=b&c=d'。
1）安装qs和vue-axios


npm install qs -S
 
npm install vue-axios -S

再此配置可查看

安装成功后会在package.json中“dependencies”中会看到安装的新库。
在提交请求时使用qs对json对象进行转换


//注意数据是直接保存到json对象
let params = {
  userNo: 'admin',
  userPwd: '123'
};
 
//参数格式转换
let paramStr = qs.stringify(params);
console.log(paramStr);
 
//提交时使用转换之后的参数
axios.post(url, paramStr).then(function(response) {
  console.log(response);
}).catch(function(error) {
  console.log(error);
});

观察控制台中的输出，已经将json格式转化为&连接的格式。查看返回结果是否是预期值。

3.2.4 简化axios使用

为简化axios使用，还可以使用axios全局配置及拦截器

1）安装vue-axios

npm install vue-axios -S

在这可查看

2）将随课件提供的api目录考到src根路径下

现在可以将在Login组件中的导入axios和qs语句删除， action.js和http.js的配置详见代码中的注释。

3）将action中的配置修改为自己的后台服务配置


export default {
	'SERVER': 'http://localhost:8080/webserver', //服务器
	'SYSTEM_USER_DOLOGIN': '/userMsg/userAction!login.action', //登陆
	'SYSTEM_USER_DOREG': '/userAction.action', //注册
  //获取完整的请求地址
	'getFullPath': k => { //获得请求的完整地址，用于mockjs测试时使用
		return this.SERVER + this[k];
	}
}

4）配置main.js


import Vue from 'vue'
 
//vue项目对axios的全局配置（增加配置）
import axios from '@/api/http'
import VueAxios from 'vue-axios'
Vue.use(VueAxios,axios)
......

5）在提交时不需要手动处理转换，全局配置进行转换。


//修改url的获取方式，url已经配置在了action.js中，这里只要指定action路径
//服务地址和服务上下文已经在http.js中设置了axios.defaults.baseURL，
//axios会根据配置自动获取。
let url = this.axios.urls.SYSTEM_USER_DOLOGIN;
this.axios.post(url, params).then(resp => {
  console.log(resp);
}).catch(resp => {});

6）发生post请求，测试

作业：
1、全局方式配置要配出来，后续需要使用axios的拦截器处理token。
2、搭建基于ssh2的后台框架，后面的课程会用到。
