我刚刚开始学习laravel。我正在使用 laravel 5.2.29 运行代码时出现错误：

Whoops, looks like something went wrong. BadMethodCallException in Controller.php line 107: Method [validate] does not exist.

哎呀，看起来出事了。Controller.php 第 107 行中的 BadMethodCallException：方法 [validate] 不存在。

Here is the error line displayed:

这是显示的错误行：

My route code:

我的路线代码：

<?php


Route::group(['middleware' => ['web']], function(){

Route::get('/', function () {
    return view('home');
})->name('home');

Route::group(['prefix'=>'do'], function(){


    Route::get('/{action}/{name?}', [
        'uses' => 'NiceActionController@getNiceAction', 
        'as' => 'niceaction'  //router name same as ->name('routername')
    ]);



    Route::post('/', [

        'uses' => 'NiceActionController@postNiceAction',
        'as'   => 'benice'

    ]);

});

});

My Controller code is given below:

我的控制器代码如下：

<?php

namespace App\Http\Controllers;


use Illuminate\Routing\Controller;
use \Illuminate\Http\Request;

class NiceActionController extends Controller
{
public function getNiceAction($action, $name=null)
{
    return view('actions.'.$action, ['name' => $name]);

}

public function postNiceAction(Request $request)
{

    $this->validate($request, [

           'action' => 'required',
           'name' =>'required'

       ]);

            return view('actions.nice',            ['action'=>$request['action'],'name'=>$this->transformName($request['name'])]);

}
private function transformName($name)
{
    $prefix='KING';
    return $prefix.strtoupper($name);
}
}

My base main controller "controller" has following code:

我的基本主控制器“控制器”具有以下代码：

<?php

namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesResources;


class Controller extends BaseController
{
use AuthorizesRequests, AuthorizesResources, DispatchesJobs, ValidatesRequests;

}

Am i missing anything????

我错过了什么吗？？？？

You need to extend the App\Http\Controllers\Controllerclass which uses the necessary ValidatesRequeststrait that implements the required validatemethod.

您需要扩展App\Http\Controllers\Controller使用ValidatesRequests实现所需validate方法的必要特征的类。

So in your NiceActionControllerclass just remove this line:

所以在你的NiceActionController课堂上只需删除这一行：

use Illuminate\Routing\Controller;

That way this line:

这样这一行：

class NiceActionController extends Controller

Will extend the proper Controllerclass from the same namespace (more precisely App\Http\Controllers\Controller), which includes the necessary traits and which already extends that Illuminate\Routing\Controllerclass (aliased as BaseController).

Controller将从相同的命名空间（更准确地说App\Http\Controllers\Controller）扩展正确的类，其中包括必要的特征并且已经扩展了Illuminate\Routing\Controller该类（别名为BaseController）。

To display errors, simply remove the line below and the closing )}

要显示错误，只需删除下面的行和结束 )}

Route::group(['middleware' => ['web']], function(){

As of 5.2, routes.php is by default already called in the context of a ['middleware'=>'web'] by RouteServiceProvider. // But in routes.php default generation of auth routes, the Route::group call is still happening by default - so if you delete that Route::group // declaration from routes.php the application then correctly shows errors.

从 5.2 开始，routeServiceProvider 默认已经在 ['middleware'=>'web'] 的上下文中调用了 routes.php。// 但是在routes.php 默认生成的auth 路由中，Route::group 调用仍然在默认情况下发生——所以如果你从routes.php 中删除Route::group // 声明，应用程序就会正确地显示错误。
