具体问题就是`$admin_id = $auth->isLogin() ? $auth->id : 0;` 这样代码得到的$admin_id为null，而不是0.   因为执行到$auth->isLogin()后的得到的结果为`true`,那么这个时候系统已经清除了相关session信息，所以$auth->id返回null值。

得到null值后，在进行写日志到adminlog表的时候，由于admin_id字段不允许为null就会报错。类似如下错误
```
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'admin_id' cannot be null
```
