### 优雅退出

```shell
kill -SIGINT $(cat .pid)
```


## 学习路线

### casbin


### jwt

``` shell
# 保存 http 的header 信息
curl -D header.txt http://localhost:8080/public/login -d 'username=admin&password=password'

```

### 优雅退出

- 进程启动，启动一个协程监听端口并提供服务。
- 创建一个退出信号的channel， 这个channel 的长度不能是0，防止未处理而丢弃。监听退出信号，通常监听的信号有 os.Interrupt 和 syscall.SIGTERM。
- 监听到信号以后，stop service，做优雅退出操作。

### 图片验证码

图片验证码的库 captcha 说明，改库提供了图片验证码的生成和验证功能。
1. 生成验证码：需要定义生成的图片验证码的 宽、高、字符范围，噪音、验证码长度等，这样就可以按照指定的规格生成验证码；生成验证码可以返回验证码的ID和图片内容信息；
2. 验证验证码：需要提供验证码的值，验证码的ID；这样就可以在验证码的存储引擎里做比对；默认的存储引擎是基于内存的，仅支持单机场景；如果要分布式场景，则需要提供redis实例；
测试脚本
``` shell
curl http://localhost:8080/public/vcode --output vcode.png -c cookie
curl -X POST -b cookie http://localhost:8080/public/vcode -d 'code=3590'
```
