主页视图的代码：

@section('content')

<div class="container">

                            {{ session('status') }}

web.php 中我的路线的代码在这里：

<?php

use Illuminate\Support\Facades\Route;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {



    return view('welcome');
});

Auth::routes();

Route::get('/home', 'HomeController@index')->name('home');

route::get('/admin/user/roles',['middleware'=>['role','auth','web'],function(){

    return "Middleware role";
}]);


route::get('/home','AdminController@index');
//route::post('/home/{name}/email/password/confirmpassword','HomeController@create');
Route::post('home', 'HomeController@create')->name('home.create');

这是 HomeController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;


class HomeController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Contracts\Support\Renderable
     */
    public function index(Request $request)
    {



         return view('home');


    }


    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
        ]);
    }
}

请告诉我我在哪里犯错因为我尝试了很多东西但它从来没有奏效:(总是出错

这是我在运行它时遇到的错误：

Answer 1

尝试公共 function 提交表单数据并使用请求而不是数组

public function create(Request $request)
    {
        return User::create([
            'name' => $request->name,
            'email' => $request->email,
            'password' => Hash::make($request->password),
        ]);
    }

Answer 2

1. Laravel 自己处理通过 GET 或 POST 方法传递的参数。
   *。 您必须在 controller 中使用Illuminate/Http/Request ，就像index function 中使用的一样。
   如果您只是显示视图，则不需要在index中使用Request $request 。
   相反，您应该在create中使用它。
   并使用它：

 public function create(Request $request) { $data = $request->validate([ // validation rules ]); $user = User::create($data); //.. anything you want }

请注意，您仍然可以将每个参数与$request->nameOfParameter使用。它的名称是您通过 HTML 表单传递的名称。 希望有用。
