Laravel - call_user_func_array() expects parameter 1 to be a valid callback
提问by Pablo
I'm getting this error:
我收到此错误：
call_user_func_array() expects parameter 1 to be a valid callback, class 'Symfony\Component\HttpFoundation\LaravelRequest' does not have a method 'url'
The code I'm using is:
我正在使用的代码是：
routes.php:
路线.php：
<?php
Route::post('', 'app@check');
Route::get('', 'app@check');
Route::post('game', 'app@game');
Route::get('game', 'app@game');
Route::get('terminos', 'app@terminos');
Route::post('save', 'scores@savescore');
Route::get('scores', 'scores@scorelist');
Route::get('scores2468', 'scores@showscores');
Event::listen('404', function()
{
//return Response::error('404');
echo "Error 404: \n";
echo Request::url();
});
Event::listen('500', function()
{
return Response::error('500');
});
Route::filter('before', function()
{
// Do stuff before every request to your application...
});
Route::filter('after', function($response)
{
// Do stuff after every request to your application...
});
Route::filter('csrf', function()
{
if (Request::forged()) return Response::error('500');
});
Route::filter('auth', function()
{
if (Auth::guest()) return Redirect::to('login');
});
scores.php:
分数.php：
class Scores_Controller extends Base_Controller {
public $restful = true;
public function get_showscores()
{
// Imprimo pantalla con tabla de resultados
$regs = array('regs' => Score::order_by('score','desc')->get());
//dd($regs);
return View::make('score.show', $regs);
}
public function post_savescore()
{
// Tomo FacebookSDK instance
$facebook = IoC::resolve('facebook-sdk');
$accessToken = $facebook->getAccessToken();
$user = $facebook->getUser();
$user_profile = $facebook->api('/me');
if ($user) {
// Logueado
$data = Input::all();
// Guardo un nuevo score
$score = Score::create(array(
'nombre' => $user_profile['name'],
'score' => $data['score'],
'fbid' => $user_profile['id']
));
return json_encode($score->attributes);
}else{
// No hay sesion
return false;
}
}
public function get_scorelist(){
$facebook = IoC::resolve('facebook-sdk');
$scores = Score::order_by('score','desc')->take(10)->get();
$response = array();
foreach($scores as $sc){
$ua = $facebook->api('http://www.facebook.com/'.$sc->attributes['fbid']);
$dat = array(
//'name' => $user->name,
'nombre' => $sc->attributes['nombre'],
'uid' => $sc->attributes['fbid'],
'score' => $sc->attributes['score']
);
array_push($response, $dat);
}
return json_encode($response);
}
}
This is part of a facebook app, as you might have noticed. The thing is that when I try to call 'save' route, I get the error posted before.
正如您可能已经注意到的那样，这是 facebook 应用程序的一部分。问题是，当我尝试调用“保存”路由时，我收到了之前发布的错误。

According to your stack trace, Laravel fires the 404 event. That means, your event handler for this throws the error.
Furthermore call_user_func' is complaining about a missing functionurl()` in your handler. so it seems to me that the call
根据您的堆栈跟踪，Laravel 会触发 404 事件。这意味着，您的事件处理程序会引发错误。此外call_user_func' is complaining about a missing functionurl()` 在您的处理程序中。所以在我看来，这个电话
echo Request::url();
is the root of all evil here. Remove it and check to see if you still get the error.
是这里万恶之源。删除它并检查是否仍然出现错误。

Use URI::current()or URI::full()instead of Request::url()
使用URI::current()或URI::full()代替Request::url()
