    <a href="#%e5%89%8d%e8%a8%80" class="header-mark"></a>前言</h1><p>之前的项目一直没有加 token 作为校验，这样的话势必会出现安全隐患。所以在项目维护的时候就添加了 JWT 和 Spring Security 作为安全防护。然而紧接着出现了一个问题，无法进行跨域请求。</p>
<h1 id="项目介绍" class="headerLink">
    <a href="#%e9%a1%b9%e7%9b%ae%e4%bb%8b%e7%bb%8d" class="header-mark"></a>项目介绍</h1><p>这个项目是我之前一直在做的一个在线自动评测系统，包括客观题和主观题。后端采用 Spring Boot ，前端之前使用 vue，结果写前端的同学找工作去了，而且前端的代码很多不规范的地方，所以借此机会就打算把前端重写一次。写之前比较了 vue react 和 angular。最后选择了 Angular， 毕竟 typescript 和 依赖注入 还有 Rxjs 这几个技术太骚了。😂</p>

    <a href="#%e9%81%87%e5%88%b0%e9%97%ae%e9%a2%98" class="header-mark"></a>遇到问题</h1><p>当重写前端的时候，采用 .http 文件测试也是可以发送和接收到请求的，然而通过 Angular 的时候发现，请求报错，出现了跨域的问题，这里说明一下，之前没有使用 Security 的时候也是处理的跨域的问题。这里贴一下代码。</p>

<p>我一直认为是前端没有处理好跨域的问题，查看了很多 Angular 的文档，并没有找到问题，于是乎我感觉到了，一定是后端的问题。紧接着想到了 Security 里面的一个参数 <code>cors</code> 当我想到了这个问题的时候立马打开了后端代码。果然 我的后端代码里，并没有写出来 这个跨域问题。</p>
