You post data can be retrieved using Input:
可以使用 Input 检索您发布的数据：
public function show()
{
$semester = Input::get('sem');
return json_encode($semester);
}
To debug it you can:
要调试它，您可以：
public function show()
{
Log::info(Input::all());
$semester = Input::get('sem');
return json_encode($semester);
}
And then execute at the console
然后在控制台执行
php artisan tail
