用构造函数

[strcmp]

request()

请求对象为模型字段，use 模型类

[yeeling]

```
if (! function_exists('request')) {
/**
* Get an instance of the current request or an input item from the request.
*
* @param string $key
* @param mixed $default
* @return \Illuminate\Http\Request|string|array
*/
function request($key = null, $default = null)
{
if (is_null($key)) {
return app('request');
}

return app('request')->input($key, $default);
}
}
```
