SPA项目开发--登录及常见问题

  • SPA项目登录功能的实现
      • 安装开发模块
      • 引入main.js配置
      • 添加elementUI组件
  • 常见问题（解决方式）
    • axios跨域问题
      • axios概念
      • axios跨域问题
    • This指针变量污染

SPA项目登录功能的实现

安装开发模块

npm install element-ui -S
在这里插入图片描述
以下依次输入执行命令：
npm install axios -S
npm install qs -S
npm install vue-axios -S

引入main.js配置

在项目中 src 目录下找到 main.js ，并在指定位置添加三行代码（ main.js 是入口文件，所以在这里引入就行，页面就不用引入了）

import Vue from ‘vue’
import ElementUI from ‘element-ui’ // 新添加 1
import ‘element-ui/lib/theme-chalk/index.css’ // 新添加 2 ，避免后期打包样式不同，要放在import App from ‘./App’; 之前
import App from ‘./App’
import router from ‘./router’
Vue.use(ElementUI) // 新添加 3
Vue.config.productionTip = false

在这里插入图片描述

添加elementUI组件

在index.js里面配置组件

在这里插入图片描述

在Element官网里面找到组件找到按钮复制适合代码块

在这里插入图片描述
引入ElementUI代码之后的效果：

常见问题（解决方式）

axios跨域问题

axios概念

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

axios跨域问题

axios.get提交没有问题，axios.post提交后台接收不到数据

会一直报错：“http://127.0.0.1:8848’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header”
因为使用了前后端分离开发，跨域访问了，解决方案：需要配置tomcat允许跨域访问，
tomcat跨域配置方法很多，但最简单的方式是自己写一个过滤器CorsFilter实现，添加一个响应头
Access-Control-Allow-Origin即可
httpResponse.addHeader(“Access-Control-Allow-Origin”, “*”);//表示任何域名
httpResponse.addHeader(“Access-Control-Allow-Origin”, “http://localhost:80”);
Access-Control-Allow-Origin: #则允许所有域名的脚本访问该资源。
Access-Control-Allow-Origin:https://www.fujieace.com #允许特定的域名访问
在这里插入图片描述

解决方案

因为POST提交的参数的格式是Request Payload，这样后台取不到数据的(详情见资料“05 Vue中axios踩坑之路-POST传参 - RainSun - CSDN博客.mht”)，
解决方案：使用qs.js库，将{a:‘b’,c:‘d’}转换成’a=b&c=d’

需要配置tomcat允许跨域访问，
tomcat跨域配置方法很多，但最简单的方式是自己写一个过滤器CorsFilter实现，添加一个响应头
Access-Control-Allow-Origin即可
httpResponse.addHeader(“Access-Control-Allow-Origin”, “*”);//表示任何域名
httpResponse.addHeader(“Access-Control-Allow-Origin”, “http://localhost:80”);
Access-Control-Allow-Origin: #则允许所有域名的脚本访问该资源。
Access-Control-Allow-Origin:https://www.fujieace.com #允许特定的域名访问

配置tomcat允许跨域访问（通过CorsFilter工具类）

package com.tanle.vue.util;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.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;/*** 配置tomcat允许跨域访问* * @author Administrator**/
public class CorsFilter implements Filter {@Overridepublic void init(FilterConfig filterConfig) throws ServletException {}@Overridepublic void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)throws IOException, ServletException {HttpServletResponse resp = (HttpServletResponse) servletResponse;HttpServletRequest req = (HttpServletRequest) servletRequest;// 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resp.setHeader("Access-Control-Allow-Origin", "*");// *,任何域名resp.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, DELETE");// resp.setHeader("Access-Control-Allow-Headers", "Origin,X-Requested-With,// Content-Type, Accept");// 允许客户端，发一个新的请求头jwtresp.setHeader("Access-Control-Allow-Headers", "Origin,X-Requested-With, Content-Type, Accept, jwt");// 允许客户端，处理一个新的响应头jwtresp.setHeader("Access-Control-Expose-Headers", "jwt");// String sss = resp.getHeader("Access-Control-Expose-Headers");// System.out.println("sss=" + sss);// 允许请求头Token// httpResponse.setHeader("Access-Control-Allow-Headers","Origin,X-Requested-With,// Content-Type, Accept, Token");// System.out.println("Token=" + req.getHeader("Token"));if ("OPTIONS".equals(req.getMethod())) {// axios的ajax会发两次请求，第一次提交方式为：option，直接返回即可return;}filterChain.doFilter(servletRequest, servletResponse);}@Overridepublic void destroy() {}
}

This指针变量污染

this指针污染问题，当前this是指的是axios，
但是当前axios并没有$message这个属性
问题：this指针并不知道指向谁
解决方案：ES6的语法箭头函数
箭头函数看上去是匿名函数的一种简写，但实际上，箭头函数和匿名函数有个明显的区别：箭头函数内部的this是词法作用域，由上下文确定。
