php - 为什么 session 在 Laravel 5.x 刷新时消失？

Question

我有一个创建 session 的简单文件，如下所示:

<?php namespace App\Repositories\Managers;

use Illuminate\Support\Facades\Session;
use Carbon\Carbon;

class SessionTest {

    public function __construct()
    {
    }

    public function sessionTest()
    {
        Session::put('test', 111);
        dd(Session::all());
    }
}

它让我的 session 如预期的那样正确。

array:4 [▼
  "_token" => "pYbrTbhnsLx6BfUNZusedQSYiBGxL3t9W7IyRVAh"
  "_previous" => array:1 [▶]
  "flash" => array:2 [▼
    "old" => []
    "new" => []
  ]
  "test" => 111
]

现在由于某种原因，当我打开另一个页面并显示 Session::all() 时，它会返回以下内容:

array:3 [▼
  "_token" => "pYbrTbhnsLx6BfUNZusedQSYiBGxL3t9W7IyRVAh"
  "_previous" => array:1 [▶]
  "flash" => array:2 [▼
    "old" => []
    "new" => []
  ]
]

基本上，一旦我打开一个新页面，它就会删除所有 session 存储。

我的 session.php 文件如下所示:

<?php

当我检查它时，似乎 session 文件没有被写入。它只存储默认值。

这里的主要问题是什么？以前从未遇到过同样的情况。

Answer 1

在 dd() 之前尝试这个命令:

Session::save()

Session::save() 将在渲染到 View 时自动调用。在您的情况下，您在调用此函数之前退出。所以你的 session 没有保存
