我更深入地研究发现会话未在SessionServiceProvider中注册.是否需要启用某些功能才能使其默认运行?由于我是Laravel的初学者，因此我不确定如何遵循上述建议.如何确保将我的路线添加到网络"组下?

I dug deeper and found that a session is not being registered in SessionServiceProvider. Is there something that needs to be enabled for this to work by default? Since I am a Laravel beginner, I am not sure how to follow the advice above. How do I make sure that my routes are added under the "web" group?

<form method="post" action="<?php echo url('/form'); ?>">
    <input type="hidden" name="_Token" value="{{ csrf_token() }}">
    <input type="text" name="Title" placeholder="Title"><br>
    <textarea rows="10" name="Content" placeholder="Content"></textarea><br>
    <input type="submit" value="Send">
</form>

推荐答案

请确保您的路线已应用 web 防盗软件.

Make sure your route has the web milddleware applied to it.

几乎所有您需要会话，csrf保护，加密的cookie，会话错误等的路由……您都需要应用网络"中间件组.

Pretty much any route where you will want sessions, csrf protection, encrypted cookies, session errors, etc ... you will need the 'web' middleware group applied.

像下面那样检查您的route.php文件中的路由组:

Check your routes.php file for the route group like so:

Route::group(['middleware' => 'web'], function () {
    //
});

更新:从5.2.27开始，RouteServiceProvider现在将您的所有路由放入已应用了web中间件的路由组的routes.php中.

Update: Since 5.2.27 The RouteServiceProvider now puts all your routes in routes.php in a route group that has the web middleware applied for you.
