laravel route to a specific url - laravel-4

Question

I want to create a route in laravel 4 with this parameters
$options = [ 'gs_bucket_name' => 'images_upload'];
$upload_url = CloudStorageTools::createUploadUrl('/upload_handler.php', $options);
which means a route that point to this $upload_url. createUploadUrl do a post at upload_handler.php and stores data to gs bucket. My problem is that post isn't performed because upload_url should be specified at routes. How can I do this?
upload_handler.php
<?php
var_dump($_FILES);
?>
view
{{ Form::open(array('action' => 'upload_handler','files' => true)) }}
{{ Form::file('file') }}
<br>
{{ Form::submit('Add Photo', array('class' => 'btn btn-primary' )) }}
{{ Form::close() }}
route
Route::group(array('before' => 'auth'), function() {
Route::post('upload_handler', function($upload_url = null) {
$options = [ 'gs_bucket_name' => 'images_upload'];
$upload_url = CloudStorageTools::createUploadUrl('/upload_handler.php', $options);
return $upload_url;
});
});
but this just returns the url. How to do post?
In pure php the code is:
require_once 'google/appengine/api/cloud_storage/CloudStorageTools.php';
use google\appengine\api\cloud_storage\CloudStorageTools;
$options = [ 'gs_bucket_name' => 'images_upload'];
$upload_url = CloudStorageTools::createUploadUrl('/upload_handler.php', $options);
?>
<div class="body">
<form action="<?php echo $upload_url ?>" enctype="multipart/form-data" method="post">
<input type="file" name="uploaded_files" size="40">
<input type="submit" value="Send">
</form>
</div>

Your question is a little vague I'm afraid but I think what you're after is Redirect::to. This will allow you to redirect the post request to the URL generated by the method on the CloudStorageTools class.
return Redirect::to($upload_url);
