Laravel 5.2 Flash 会话不工作

Question

这是我的routes.php 文件：

Route::get('advertise', ['as' => 'advertise', 'uses' => 'AdvertiseController@index']);

这是App\Exceptions\Handler.php文件的相关部分：

public function render($request, Exception $e)
{
    switch ($e)
    {
        case ($e instanceof AdvertiserNotFoundException):
            return redirect()->route('advertise')->with('status', 'Advertiser not found.');
        default:
            return parent::render($request, $e);
    }
}

这是我（试图）显示消息的方式：

@if (session('status'))
    <div class="alert alert-success">
        {{ session('status') }}
    </div>
@endif

它正确捕获了AdvertiserNotFoundException 并重定向到路由advertise，但响应没有携带任何闪存数据。

我不包括 web 中间件，因为默认情况下所有路由都被它覆盖。

with() 函数用于将数据从控制器传递到视图。

您需要使用会话设置数据如下：

case ($e instanceof AdvertiserNotFoundException):
    session('status', 'Advertiser not found.');
    return redirect()->route('advertise');
