Question

我整天都收到此错误，似乎无法正确解决。我的目标基本上是更新admin_users表中的用户，以更改其角色。

这是错误。

Symfony \组件\ HttpKernel \ Exception \ MethodNotAllowedHttpException没有消息Laravel 5.7

Web.php

Route::get('/dashboard', 'DashboardController@dashboard');
Route::post('/admin_users', 'AdminUController@admin_users')->name('admin_users.update');
Route::get('/admin_users', 'AdminUController@admin_users')->name('admin_users');

这是Controller AdminUController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Post;
use Mail;
use Session;
use Gate;
use App\Admin_users;

class AdminUController extends Controller
{

    public function admin_users(){

        if(!Gate::allows('isUser')){
            if(!Gate::allows('isAdmin')){
                abort(404,"Sorry, There is nothing to see here!");
            }
       }

        // data from users table to be passed to the view
        $admin_users = Admin_users::all();

         $title = 'Earn, Invest, Save, and Learn with the Invo App';
         return view('admin_users', ['admin_users' => $admin_users])->with('title',$title);
     }

     public function update(Request $request, Admin_users $admin_users){
        $admin_users->email = $request->email;
        $admin_users->user_type = $request->user_type;
        $admin_users->save();
        session()->flash('User account has been updated!');
        return redirect()->back();
     }
}

这是模型Admin_users.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Admin_users extends Model
{
    protected $guarded=[];
    //public function admin_users(){

   // }
}

这是刀片服务器模板admin_users.blade.php

Answer 1

我无法发表评论，不是因为您需要允许put方法通过路线吗？：）

Route::put($uri, $callback);

来自此处的文档：

https://laravel.com/docs/5.7/routing

所以我相信答案是：

Route::put('/admin_users', 'AdminUController@admin_users')->name('admin_users.update');

Put并不是我大量使用的一种方法，所以我纯粹是根据我在Laravel上的经验来谈论，而不是与put一起使用，如果我不赞成的话，他们会道歉错误的路径：）

Answer 2

出现此错误的主要原因是，您将表单设置为使用PATCH方法提交，并且设置了查找PUT方法的路线。

您还可以将路线设置为：

Route::match(['put', 'patch'], '/admin_users/update/{id}','AdminController@update');

或者，您可以使用php artisan make:controller AdminUController --resource

Laravel资源路由通过单行代码将典型的“ CRUD”路由分配给控制器。例如，您可能希望创建一个控制器来处理admin_users的所有HTTP请求

那么您的资源路线将类似于：

Route::resource('admin_users', 'AdminController');
