Laravel 8 返回视图空白页或白屏

Question

我的 laravel 8 有问题.. 我为编辑配置文件创建了控制器，当我访问该页面时，它返回查看空白页面或白屏，没有错误..

这是我的控制器

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;

class ProfileController extends Controller
{
    public function edit(Request $request)
    {
        return view('profile.edit', [
            'user' => $request->user()
        ]);
    }
}

这是我的路线或 web.php（最后是编辑配置文件的路线）

Route::group(['prefix' => 'dashboard', 'middleware' => ['auth']], function () {
    Route::get('/', [App\Http\Controllers\DashboardController::class, 'index'])->name('dashboard.index');
    Route::get('/categories/select', [App\Http\Controllers\CategoryController::class, 'select'])->name('categories.select');
    Route::resource('/categories', App\Http\Controllers\CategoryController::class);
    Route::get('/tags/select', [App\Http\Controllers\TagController::class, 'select'])->name('tags.select');
    Route::resource('/tags', App\Http\Controllers\TagController::class);
    Route::resource('/posts', App\Http\Controllers\PostController::class);
    Route::resource('/banners', App\Http\Controllers\BannerController::class);
    Route::resource('/clients', App\Http\Controllers\ClientController::class);
    Route::resource('/gallerys', App\Http\Controllers\GalleryController::class);
    Route::resource('/products', App\Http\Controllers\ProductController::class);
    Route::resource('/services', App\Http\Controllers\ServiceController::class);
    Route::resource('/teams', App\Http\Controllers\TeamController::class);
    Route::resource('/testimonies', App\Http\Controllers\TestimonyController::class);
    Route::resource('/metas', App\Http\Controllers\MetaController::class);
    Route::resource('/keywords', App\Http\Controllers\KeywordController::class);
    Route::group(['prefix' => 'filemanager'], function () {
        Route::get('/index', [App\Http\Controllers\FileManagerController::class, 'index'])->name('filemanager.index');
        \UniSharp\LaravelFilemanager\Lfm::routes();
    });
    Route::group(['middleware' => 'auth'], function () {
        Route::get('/profile', [App\Http\Controllers\ProfileController::class, 'edit'])->name('profile.edit');
    });
});

这是我的观点

@extends('layouts.dashboard')

@section('title')
Edit Profile
@endsection

@section('breadcrumbs')
{{ Breadcrumbs::render('edit_profile') }}
@endsection

@section('content')

我仍然在本地服务器上工作，有人知道问题出在哪里吗？

我认为您的控制器代码存在问题。请尝试以下代码。我更改了用户获取语法。

    <?php

    namespace App\Http\Controllers;

    use App\Http\Controllers\Controller;
    use Illuminate\Http\Request;

    class ProfileController extends Controller
    {
        public function edit(Request $request)
        {
            return view('profile.edit', [
                'user' => \Auth::user()
            ]);
        }
    }
