php - 使用重定向类时 Laravel 白屏

Question

当我在处理数据后尝试使用 Laravel Redirect 类重定向我的用户时，我目前遇到白屏死机。如果我使用 native php-function header("location ...")，应用程序会正确响应并以愉快的方式发送给用户，但是使用 Laravel 的 Redirect 类，站点会崩溃并显示白屏。我已经尝试了 Redirect::action 和 Redirect::to 函数，但它们都导致了同样令人恼火的死机白屏。 laravel.log 没有显示任何内容......

有没有人有什么想法？

这是数据处理程序 Controller 类的代码:

<?php
class ManagerLayoutDataController extends BaseController 
{
public function route($action, $moduleID) {
    if(method_exists('ManagerLayoutDataController',$action)) {
        $this->$action($moduleID);
    }
    // Invalid action (method not found)
    else {
        die('Action routing error');
        //return Redirect::to('/');
    }
}

public function updateHeaderBg($moduleID) {
    $image = Input::file('img');
    $user = Auth::user();
    $siteID = $user->getSiteID();

    $layoutDataMessage = null;

    // Validate file upload (NOT FILE CHARACTERISTICS)
    if(Input::hasFile('img') && $image->isValid() && isset($siteID) && $siteID !== "") {
        $res = ManagerFileUpload::uploadImage($siteID, $image);
        if($res->success) {
            $fileName = $res->fileName;
            $dbViewModule = ViewModuleRepository::getModule($moduleID);
            if($dbViewModule->type === DBViewModule::MODULE_TYPE_HEADER) {
                $headerModule = new HeaderModule($dbViewModule);
                $headerModule->updateBgImage($fileName);
                $layoutDataMessage = new LayoutDataMessage(LayoutDataMessage::STATUS_SUCCESS,"");
            }
        }
        else {
            $layoutDataMessage = new LayoutDataMessage(LayoutDataMessage::STATUS_FAIL,$res->message);
        }

    }
    else {
        $layoutDataMessage = new LayoutDataMessage(LayoutDataMessage::STATUS_FAIL, "Bilden kunde inte laddas upp.");
    }

    if($layoutDataMessage != null) {
        return Redirect::action('ManagerLayoutController@main')->with('message',$layoutDataMessage);
        //return Redirect::to('manager/layout/');
        //header('location: */manager/layout');
    }
    else {
        return Redirect::action('ManagerLayoutController@main')->with('message',LayoutDataMessage(LayoutDataMessage::STATUS_FAIL, "Bilden kunde inte laddas upp."));
        //return Redirect::to('manager/layout/');
        //header('location: */manager/layout');
    }
}
}

Answer 1

尝试添加

ini_set('display_errors', 1);

它至少应该告诉您实际错误是什么。这仅适用于开发模式，当你进入生产模式时将其删除
