我可以使用此代码获得第一个结果

public function search(Request $request)
{
$record = St::where('pn', $request->input)->first();
$param = ['input' => $request->input, 'record' =>$record];
return view('contacts.find', $param);

}

但是，我这样改变了

$ record = St :: where('pn'，$ request-> input)-> get();

错误显示

方法照亮\\\\ Database \\\\ Eloquent \\\\ Collection :: getData不存在

有人可以告诉我为什么吗？

我的版本是5.6
