如果 url 参数然后返回视图，否则转到 Laravel 路由中的控制器

Question

我有一个SearchController，它设置了一个会话变量并将用户发送到staff.resultList视图。 有一个链接可以将视图从列表切换到网格视图。 我正在尝试添加一个条件语句来促进该切换。在我的路由文件中，我有：

Route::get('home/memberhome/search', function(){
    if(isset($_GET['resultView']) && Session::has('lastSearch')){
        if($_GET['resultView'] == 'grid'){
            return view('staff.resultsGrid');
        } else {
            return view('staff.resultList');
        }
    } else {
        'SearchController@getAvailablity';
    }
});

显然这不起作用，但我不确定正确的语法来让它运行控制器，如果条件不是这个意思，如果满足条件，只显示视图。

我可以完成这项工作还是应该使用不同的方法？

路由文件

<?php
/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.

// use IlluminateHttpRequest;
// use Mail;
Route::get('/', function () {
    return redirect('home/memberhome');
});

        } else {
            return view('staff.resultList');
        }
    } else {

Answer 1

您可以将用户重定向到另一个控制器的操作，如下所示：

return redirect()->action('SearchController@getAvailablity');

所以它会是这样的：

Route::get('home/memberhome/search', function(){
    if(isset($_GET['resultView']) && Session::has('lastSearch')){
        if($_GET['resultView'] == 'grid'){
            return view('staff.resultsGrid');
        } else {
            return view('staff.resultList');
        }
    } else {
        return redirect()->action('SearchController@getAvailablity');
    }
});

更新

如果控制器的方法未在任何路由中注册，则可以像这样访问它：

return app(AppHttpControllersSearchController::class)->getAvailablity();

所以它会是这样的：

Route::get('home/memberhome/search', function(){
    if(isset($_GET['resultView']) && Session::has('lastSearch')){
        if($_GET['resultView'] == 'grid'){
            return view('staff.resultsGrid');
        } else {
            return view('staff.resultList');
        }
    } else {
        return app(AppHttpControllersSearchController::class)->getAvailablity();
    }
});
