<p>2.前端接收<code>http://localhost/prod-api/captchaImage</code> 请求，通过下面的配置重写url，然后再将请求发送给后端（通过<code>[&#39;^&#39; + process.env.VUE_APP_BASE_API]: &#39;&#39;</code>配置将<code>http://localhost/prod-api/captchaImage</code>重写为<code>http://localhost:8080/captchaImage</code>）</p>

<p><strong>实现思路</strong></p>
<p>1.后端生成一个计算表达式 ，例如 1+1&#x3D;?@2</p>
<p>2.然后将1+1&#x3D;?以流的方式传递给前端，前端展示为图片，同时后端也会传递一个UUID给前端，这个UUID为就是<code>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx</code>，2作为结果value值存入Redis中。存入Redis中的key的格式为<code>captcha_codes:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx</code> </p>
<p>3.用户在填写完表单之后会携带账号、密码、验证码的结果值，以及之前后端传递给前端的UUID值给后端，后端会先以<code>captcha_codes:+UUID</code>作为key在reidis中查找value值，再和前端输入的验证码结果值作比较，如果验证码相同再比较账号密码，账号密码在数据库中也可以匹配上就登录成功，反之返回给前端账号密码错误；如果验证码不相同，直接返回给前端，验证码错误。</p>
<p><strong>代码实现</strong></p>
<p>1.前端在页面初始化或者刷新验证码的时候会调用下面的方法获取验证码和UUID值</p>
