简单的联系表单没有显示验证错误或发送消息

我在Laravel 5中有一个简单的联系人表单。如果我用空字段提交，页面会重新加载，但不会显示验证的错误消息。如果我填写表单并提交，就会得到以下错误:

FileViewFinder.php第140行InvalidArgumentException: View [email .php][消息]未找到。

那是因为我没有这样的观点，我不知道该放什么进去，Laravel的文档对这个主题也不清楚:

传递给send方法的第一个参数是应该用作电子邮件正文的视图的名称。

不知道那是什么意思

Route::get('contact','HomeController@contactus');
Route::post('contact_request', 'HomeController@contactRequest');

HomeController

public function contactus()

        if (Auth::check()) {
            $count = Cart::count();
        } else {
            $count = 0;
        }
        $contact = Contact::all();
        return view('contact')->with('contact', $contact)->with('count', $count);
    }
public function contactRequest() {
        if (Auth::check()) {
            $count = Cart::count();
        } else {
            $count = 0;
        }
        $contact = Contact::all();
        //Get all the data and store it inside Store Variable
        $data = Input::all();
