当从中间件返回控制器操作时，在null上对成员函数setCookie()进行Laravel调用

Question

你好优秀的开发人员，

这不是直接复制：Call to a member function setCookie() on null，因为我正在从中间件调用Controller操作，然后在控制器操作中返回视图，

这是我从web.php出发的路线

Route::get('/end', [EndPageController::class, 'index'])
->name('survey.end')
->middleware('App\Http\Middleware\LegacyEndCheck');

中间件LegacyEndCheck.php处理功能

public function handle($request, Closure $next)
{
    $sjid = $request->input('sjid', false);

    if( empty($sjid) || strlen($sjid) !== 36 ){
        return app()->make(EndLegacyController::class)->index($request); //I have to call EndLegacyController@index here as I can't change URL using redirect route
    }

    return $next($request);
}

控制器EndLegacyController index动作

public function index(Request $request)
{
    $sjid = $request->input('sjid',false);
    $status = $request->input('status',false);
    if( empty($sjid) || empty($status) ){
        $this->status = 5;
        return view('survey.legacy.end')
            ->with('status', $this->status);
    }
    dd('allright');
}

​

到目前为止，由于无法在中间件中直接返回视图，因此我不知道如何解决这个问题，由于更多的业务逻辑，它必须通过我的控制器返回。

请帮助我理解和解决这个问题。

Answer 1

Laravel生命周期通过所有中间件发送您的请求，您所做的实际上是用一个新的视图替换当前的响应。只有响应或请求应该在此流程中。这是一种反模式，最好是重定向。这将使laravels的生命周期试图在视图上运行其中间件，并尝试在其上设置cookie。

如果您返回一个带有响应的视图，它现在可以向它添加一个cookie。但是，您以一种恶意的方式拦截请求响应生命周期。

return Response::view('survey.legacy.end', [ 'status' => $status, 'respstatus' =>  $respstatus, 'rowSurvey' => $rowSurvey ]);
