Laravel Method [validate] does not exist.

今天写东西遇到这个错误

Whoops, looks like something went wrong.

 

保存下来

 

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Routing\Controller;
use Illuminate\Support\Facades\DB;
use App\Model\Group;
use Illuminate\Contracts\Http;



class GroupController extends Controller{

    public $timestamps = true;
    public function index(){
        $group=  Group::distinct()->get();
        $name = 'chaoguan';
        return view('Group/index',['name'=>$name,'group'=>$group]);
    }
    public function addGroup(Request $request){
$input_many=$request->except(['_token','create_time']);
$rules = [
];
$messages = [
];
$this->validate($request, $rules, $messages);
return redirect()->back();
    }
}

 

出现错误的代码如上

后来我又跟之前写的控制器进行了文本比较

 

错误在这儿

 

多了一个 

use Illuminate\Routing\Controller;

不用乱use啊

网上查了很多都没有找到答案，最后还是自己找到，遇到问题自己还是要先思考
