Laravel 有时显示 404 未找到页面

Question

我正在Laravel 8上工作，有时当我刷新页面或通过显示的链接直接打开它时会遇到问题

未找到页面 404 错误，我在互联网上尝试了很多解决方案，但没有解决方案适合我。

另一个注意事项：当我使用ajax发送请求时，它也会向我显示，这是向我显示的最多时间。

我的web.php：

<?php

use App\Http\Middleware\AdminAuth;
use Illuminate\Support\Facades\App;
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!

*/

$adminPathName = env('ADMIN_PATH');

Route::get($adminPathName . '/test/{locale}', function ($locale) {
    session('lang', 'en');

    app()->setLocale($locale);
    echo App::getLocale();
});

Route::get('/', function () {
    return view('frontend.home');
});

$adminPathName = env('ADMIN_PATH');
$userPath = env('USER_PATH');

Route::get($adminPathName . '/login', 'Admin\LoginController@login');
Route::post($adminPathName . '/signin', 'Admin\LoginController@signin');
Route::group(['middleware' => ['AdminAuth']], function () {
    $adminPathName = env('ADMIN_PATH');
    Route::get($adminPathName . '/dashboard', 'Admin\AdminController@home');
    Route::get($adminPathName . '/languages/manage-languages', 'Admin\LanguageController@index');
    Route::post($adminPathName . '/languages/add-language', 'Admin\LanguageController@addLanguage');
    Route::post($adminPathName . '/languages/add-translate', 'Admin\LanguageController@addTranslate');
    Route::post($adminPathName . '/languages/update-translate', 'Admin\LanguageController@updateTranslate');
    Route::post($adminPathName . '/languages/remove-translate', 'Admin\LanguageController@removeTranslate');
    Route::post($adminPathName . '/languages/remove-language', 'Admin\LanguageController@removeLanguage');
    Route::post($adminPathName . '/languages/sync-language', 'Admin\LanguageController@syncLanguage');

});


// todo this route should be added below .
Route::get('/login/facebook/callback', 'User\LoginController@facebookCallback');

Route::group(['prefix' => '/{locale}', 'middleware' => \App\Http\Middleware\SetLocale::class, 'as' => 'locale'], function () {

    $userPath = env('USER_PATH');

    Route::get('/', function () {
        return view('frontend.home');
    });
    Route::get($userPath . '/login', 'User\LoginController@login');
    Route::post($userPath . '/signin', 'User\LoginController@signin');
    Route::get($userPath . '/create-account', 'User\UserController@createAccount');
    Route::post($userPath . '/complete-register', 'User\UserController@completeRegister');

    /* Facebook Login & Register  */

    Route::get($userPath . '/social/facebook/redirect', 'User\LoginController@facebookRedirect');
    /* ./ Facebook Login & Register  */

    /* Google Login & Register  */
    Route::get($userPath . '/social/google/redirect', 'User\LoginController@googleRedirect');
    Route::get($userPath . '/social/google/callback', 'User\LoginController@googleCallback');
    /* ./ Google Login & Register  */

    Route::get('/change-language/{lang}', 'User\WebSiteController@changeLanguage');

    Route::group(['middleware' => ['UserAuth']], function () {
        $userPath = env('USER_PATH');
        Route::get($userPath . '/dashboard', 'User\UserController@dashboard');
        Route::get($userPath . '/update-profile', 'User\UserController@userProfile');
        Route::get($userPath . '/website/create-website', 'User\WebSiteController@newWebsite');
        Route::post($userPath . '/card/upload-gallery', 'User\UserController@uploadGallery');
        Route::get($userPath . '/cards/new-card/{card_lang}', 'User\CardController@newCard');
        Route::get($userPath . '/cards/new-card/{card_lang}/{card_key}', 'User\CardController@newCard');
        Route::post($userPath . '/cards/get-card-gallery', 'User\CardController@getGalleryByCardId');
        Route::post($userPath . '/cards/update-card', 'User\CardController@updateCard');
        Route::post($userPath . '/cards/update-card-logo', 'User\CardController@updateCardLogo');

        Route::get($userPath . '/logout', function () {
            auth('UserAuth')->logout();
            return redirect(ulocale_path('/login'));
        });
    });


});


Route::group(['domain' => '{account}.localhost'], function () {
    Route::get('/{id}/card', 'User\CardController@shoBusinessCardById');
});

和.htaccess文件

RewriteEngine On
<IfModule mod_rewrite.c>
 #Session timeout

<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

   Options +FollowSymlinks
   RewriteEngine On

   # Redirect Trailing Slashes...
   RewriteRule ^(.*)/$ /$1 [L,R=301]

RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ ^$1 [N]

RewriteCond %{REQUEST_URI} (\.\w+$) [NC]
RewriteRule ^(.*)$ public/$1

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php


</IfModule>

大多数情况下，错误显示在以下路线中：

 Route::post($userPath . '/cards/get-card-gallery', 'User\CardController@getGalleryByCardId');

控制器端getGalleryByCardId：

public function getGalleryByCardId(Request $request)
{
    $imgs = DB::table('card_docs')
        ->where('user_id', usession('user_id'))
        ->where('card_key', $request->card_key)->get();

    return $imgs;
}

Answer 1

根据您的描述，我认为env()您的路由文件中的调用可能是问题所在。

.env当 Laravel由于加载时间延迟或任何其他问题而无法从文件中读取环境值时，它不会给出与环境变量不可用相关的任何错误，但会继续处理。

由于您的路线文件用于从不可用的值env()中获取值，.env因此您的路线的 url 会发生变化，因此您可能会收到 404 错误。

如果加载环境变量时出现问题，但执行将继续，则将导致 $userPath 和 $adminPath 的值均为null $userPath = env('USER_PATH')。$adminPath = env('ADMIN_PATH')

因此，无论在 url 中使用这些变量的地方，这些 url 都会以 null 作为值进行更改

当您收到 404 时，您可以检查错误日志：如果它们有任何数据库或加密相关错误的条目 - 很可能是由于 DotEnv 无法按时.env读取

@Donkarnash 实际上我不是 Laravel 的专业人士，如何将其放入配置文件中？你能为我解释一下吗？

您可以以任何您喜欢的名称创建一个新文件，config/custom.php而不是custom.php

return [
    'userPath' => env('USER_PATH'),
    
    'adminPath' => env('ADMIN_PATH'),
];

然后您可以在路由文件中进行更改以将这些值与config()帮助程序一起使用

Route::get(config('custom.adminPath') . '/login', 'Admin\LoginController@login');
Route::post(config('custom.adminPath') . '/signin', 'Admin\LoginController@signin');
Route::prefix(config('custom.adminPath'))
    ->middleware(['AdminAuth'])
    ->group(function () {
        Route::get('/dashboard', 'Admin\AdminController@home');
        Route::get('/languages/manage-languages', 'Admin\LanguageController@index');
        Route::post('/languages/add-language', 'Admin\LanguageController@addLanguage');
        Route::post('/languages/add-translate', 'Admin\LanguageController@addTranslate');
        Route::post('/languages/update-translate', 'Admin\LanguageController@updateTranslate');
        Route::post('/languages/remove-translate', 'Admin\LanguageController@removeTranslate');
        Route::post('/languages/remove-language', 'Admin\LanguageController@removeLanguage');
        Route::post('/languages/sync-language', 'Admin\LanguageController@syncLanguage');
        Route::get('/languages/translate/{langId}', 'Admin\LanguageController@translateById');
    });

// todo this route should be added below .
Route::get('/login/facebook/callback', 'User\LoginController@facebookCallback');

Route::prefix('/{locale}/' . config('custom.userPAth'))
    ->middleware([\App\Http\Middleware\SetLocale::class])
    ->as('locale')
    ->group(function () {
        Route::get('/', function () {
            return view('frontend.home');
        });
        Route::get('/login', 'User\LoginController@login');
        Route::post('/signin', 'User\LoginController@signin');
        Route::get('/create-account', 'User\UserController@createAccount');
        Route::post('/complete-register', 'User\UserController@completeRegister');
        /* Facebook Login & Register  */

        Route::get('/social/facebook/redirect', 'User\LoginController@facebookRedirect');
        /* ./ Facebook Login & Register  */

        /* Google Login & Register  */
        Route::get('/social/google/redirect', 'User\LoginController@googleRedirect');
        Route::get('/social/google/callback', 'User\LoginController@googleCallback');

        Route::get('/change-language/{lang}', 'User\WebSiteController@changeLanguage');
        Route::group(['middleware' => ['UserAuth']], function () {
            Route::get('/dashboard', 'User\UserController@dashboard');
            Route::get('/update-profile', 'User\UserController@userProfile');
            Route::get('/website/create-website', 'User\WebSiteController@newWebsite');
            Route::post('/card/upload-gallery', 'User\UserController@uploadGallery');
            Route::get('/cards/new-card/{card_lang}', 'User\CardController@newCard');
            Route::get('/cards/new-card/{card_lang}/{card_key}', 'User\CardController@newCard');
            Route::post('/cards/get-card-gallery', 'User\CardController@getGalleryByCardId');
            Route::post('/cards/update-card', 'User\CardController@updateCard');
            Route::post('/cards/update-card-logo', 'User\CardController@updateCardLogo');

            Route::get('/logout', function () {
                auth('UserAuth')->logout();

                return redirect(ulocale_path('/login'));
            });
        });
    });

Route::group(['domain' => '{account}.localhost'], function () {
    Route::get('/{id}/card', 'User\CardController@shoBusinessCardById');
});

通过使用配置中的值而不是 env，您可以通过配置缓存获得好处。

在生产中，您还可以通过缓存路由来缓解与路由 url 相关的问题 - 但为此，您需要将基于闭包的路由转换为基于控制器的路由。
