 ## Swagger文档访问地址
 http://localhost:3000
 
+## 在swagger中添加token验证
+① 先请求验证码接口，拿到验证码（info字段就是验证码）
+② 然后请求登录接口，你可以在网页的Network中拿到登录成功后返回的token，复制
+③ 最后回到swagger，点击右上角的绿色边框Authorize，你会看到一个Value的输入框，将复制的token前面加上Bearer 粘贴上去，点确定即可（Authorize）
+（注意Bearer后面有一个空格哦）
+
 ## 注意点
 请先全局安装typescript、ts-node，如安装请忽略
 ```
