Question

尝试在我的laravel项目中使用pusher实现评论系统。一切似乎都井井有条，但是每个将输入数据发送到数据库的后期请求都会返回错误500。在firefox上使用F12监视发送到/ tip / select的内容，似乎它可以很好地传递注释文本，因此可能是控制器的问题。

路线 Route::get('/tip/select','TipController@select'); Route::post('/tip/select', 'TipController@addComment');

评论模型

namespace App;

use Illuminate\Database\Eloquent\Model;
use Zttp\Zttp;
use App\model\User;
use App\Tip;

class Comment extends Model
{
protected $guarded = [];

protected $table='comments';
//protected $fillable=['tip_id','user_id','body'];
public static function moderate($comment)
       {
           $response = Zttp::withoutVerifying()->post("https://commentator.now.sh", [
               'comment' => $comment,
               'limit' => -3,
           ])->json();
           if ($response['commentate']) {
               abort(400, "Comment not allowed");
           }
       }
public function tip(){
 return $this->belongsTo('App\Tip');
}
public function user(){
 return $this->belongsTo('App\model\User');
}
}
