更新后，作曲家laravel给出ReflectionException错误我做什么

Question

我正在进行laravel项目。我是laravel的新手。我在adminlte上安装了laravel。Laravel使用我自己创建的控制器工作得很好，但当我打开auth/login或logout和public/home时，它会给我ReflectionException错误

Answer 1

发生这种情况是因为某些控制器试图使用web中间件组。https://laravel.com/docs/5.2/middleware#middleware-分组

您可以在HttpKernel.php中定义此组来解决问题：

protected $middlewareGroups = [
    'web' => [
        AppHttpMiddlewareEncryptCookies::class,
        IlluminateCookieMiddlewareAddQueuedCookiesToResponse::class,
        IlluminateSessionMiddlewareStartSession::class,
        IlluminateViewMiddlewareShareErrorsFromSession::class,
        AppHttpMiddlewareVerifyCsrfToken::class,
    ],
];

Answer 2

composer.json中的更改this：

"acacha/admin lte模板laravel"："1.*"

为此：

"acacha/admin lte模板laravel"："1.0.5"

然后运行：composer更新
