如何从Laravel中的其他控制器访问控制器

也许我做错了。但我正在Laravel做我的第一个MVC。这是我的设置。

该应用程序将从varoius源下载数据，并保存到数据库中进行输出。

我有两个控制器。一个将数据保存到数据库，另一个从instagram下载数据。在Instagram控制器中。我目前只是输出数据。我想用我的保存控制器来保存它。

Instagram控制器：

class InstagramController extends BaseController {
public function read($q)
{
    $client_id = 'ea7bee895ef34ed08eacad639f515897';
    $uri = 'https://api.instagram.com/v1/tags/'.$q.'/media/recent?client_id='.$client_id;
    $response = $this->sendRequest($uri);
    print_r(json_decode($response));
    //return json_decode($response);
}
public function sendRequest($uri){
    $curl = curl_init($uri);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
    $responses = curl_exec($curl);
    $responses = json_decode($responses);
    curl_close($curl);
    echo '<pre>';
    foreach ($responses->data as $data) {
        //0/{postid}/{url}/{author}/{content}
        $type = 0;
        $postid = $data->id;
        $url = $data->link;
        $author = $data->user->username;
        $content = $data->images->standard_resolution->url;

        echo $type.' '.$postid.' '.$url.' '.$author.' '.$content.'<br />';
    }
    //var_dump($responses->data);
    echo '</pre>';
    //return $response;
}
}

保存控制器：

class PostController extends BaseController {
public function save($type, $postid, $url, $author, $content)
{
    $post = new Post;
    $post->type = $type;
    $post->postid = $postid;
    $post->url = $url;
    $post->author = $author;
    $post->content = $content;
    try
    {
    $post->save();
    echo $post;
    }catch(Exception $e){
        throw new Exception( 'Already saved', 0, $e);
    }
   // 
}
}
