页面刷新后 Laravel 会话丢失

Question

我对 Laravel 中的会话有一点问题。

我做了这样的认证功能：

public function postSignin(){
        $attempt = Auth::attempt(array('username' => Input::get('username'), 'password' => Input::get('password')));
        if ($attempt) {
            return Redirect::to('index')->with('message', 'Anda telah login!' . $attempt)
                                        ->with('usersess', Input::get('username'));
        } else if(!$attempt){
                return Redirect::to('auth')
                            ->with('message', 'Kombinasi email/password salah ' . $attempt)
                            ->withInput();
        }
    }

让我看看我已将 'usersess' var 发送到我在我的标题刀片中使用的会话中，如下所示：{{ Session::get('usersess') }} 并将其放在标题中。

但问题是当我刷新页面时，会话丢失了！是否有任何线索，如何在不丢失会话的情况下将其取回？

我已经了解了 php，使用 <?php session_start() ?> 是基本功能，但它在 laravel 中是如何工作的？

谢谢！

更新我的 session.php 配置

Answer 1

->with 仅为该页面加载将数据闪烁到会话中。如果您想在会话中保留项目，请使用Session::put('key', 'value')。所以对于你的例子：

if($attempt) {
    Session::put('usersess', Input::get('username'));
    return Redirect::to('index')->with('message', 'Anda telah login!' . $attempt);
}

编辑

您可以使用Session::get('key') 检索值或使用Session::pull('key') 返回值并忘记该值。您还可以使用Session::forget('key') 删除项目。 Session::flush() 清除会话中的所有内容。

Answer 2

我在使用时遇到了这个问题

use Illuminate\Support\Facades\Session;

你可以用它来代替它

use Symfony\Component\HttpFoundation\Session\Session;

还有：

//to set a session variable use
$session = new Session();
$session->set('variableName', $requestData['key']);

//to get that session variable
$session = new Session();
$session->get('variableName');

Answer 3

我想为此做出贡献，因为我遇到了同样的问题，但我的解决方案与投票的不同。

将项目放入我的会话后，它们似乎在下一页加载时消失了。

我这样做的方式是通过 AJAX 调用。每当我进行 AJAX 调用时，我总是在最后使用 exit，以防止任何不必要的页面处理。我发现这个exit 阻止了 Laravel 进一步进行并将数据写入永久会话。

星狐之声：祝你好运！

这显然不是你的问题，但对于发现这个问题并且接受的答案不能解决你的问题的其他人来说，这可能：

如果您将 laravel 会话存储在数据库中，则该会话值的大小是有限制的。 Laravel 会话迁移有一个名为“payload”的字段，它是一个文本类型。如果您超出该字段的限制，则整个会话将被终止。当我将 json 模型数据动态添加到我的会话时，这发生在我身上。

Schema::create('sessions', function (Blueprint $table) {
    $table->string('id')->unique();
    $table->text('payload');
    $table->integer('last_activity');
});

检查您是否没有删除 .js 中的 cookie。 这对我来说是个问题：

var now = new Date();
now.setTime(now.getTime()+(-1*24*60*60*1000));
var expires = "=;"+" path=/; expires="+now.toUTCString();
document.cookie = "lastpage"+expires;
