当我在处理数据后尝试使用Laravel Redirect类重定向用户时，当前出现白屏死机。如果我使用 native php函数 header (“location ...”)，则应用程序会正确响应并以愉快的方式发送用户，但是使用Laravel的Redirect类，网站将崩溃并显示白屏死机。我已经尝试了Redirect::action和Redirect::to函数，但是它们都导致相同的令人讨厌的死亡白屏。 laravel.log没有显示任何内容...
有人有什么想法吗？
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');
}
}
}

最佳答案
尝试添加
ini_set('display_errors', 1);
它至少应该告诉您实际错误是什么。
这仅用于开发模式，投入生产后将其删除
