Why is my Laravel 5.7 session not working?
提问by HartleySan
I'm trying to get sessions to work in Laravel 5.7, but I can't seem to get it working; I'm not sure why. I've looked at the official docs, looked at a bunch of SO posts, done Googling for the issue on other sites, and I still can't figure it out.
我试图让会话在 Laravel 5.7 中工作，但我似乎无法让它工作；我不知道为什么。我查看了官方文档，查看了一堆 SO 帖子，在其他网站上搜索了该问题，但我仍然无法弄清楚。
Basically, I've got a route like the following in web.php:
基本上，我有一条如下所示的路线web.php：
Route::get('/some_path', 'SomeController@index');
Then, in the indexmethod of SomeController, I have the following:
然后，在 的index方法中SomeController，我有以下内容：
session(['test', 'Some Value']);
session(['test2', 'Some Other Value']);
session(['test3', 'Some Third Value']);
$value = session('test', 'Backup Value');
echo $value;
With that, I'm always getting Backup Valueechoed to the screen.
有了这个，我总是Backup Value在屏幕上回响。
If I go into /storage/framework/sessions, I see a session file that has the following content (which I have anonymized):
如果我进入/storage/framework/sessions，我会看到一个会话文件，其中包含以下内容（我已将其匿名化）：
a:5:{s:6:"_token";s:40:"token-here";s:9:"_previous";a:1:{s:3:"url";s:26:"http://example.com/some_path";}s:6:"_flash";a:2:{s:3:"old";a:0:{}s:3:"new";a:0:{}}i:0;s:5:"test3";i:1;s:16:"Some Third Value";}
Basically, it looks like the session is kind of working, but it only seems to store test3. If I comment out the test3line in the controller, then it only stores test2. And even if I only have the testline in the controller, it still doesn't retrieve the value.
基本上，看起来会话有点工作，但它似乎只存储test3. 如果我注释掉test3控制器中的行，那么它只存储test2. 即使我test在控制器中只有一行，它仍然没有检索到值。
I also tried switching the session to a DB session with the proper session migrate file a la https://laravel.com/docs/5.7/session, but it's still not working.
我还尝试使用正确的会话迁移文件将会话切换到数据库会话，例如https://laravel.com/docs/5.7/session，但它仍然无法正常工作。
Basically, I have no clue what's up. I can say that I'm not using the native Laravel auth, so I'm not sure if that matters, but I feel like it shouldn't. Also, I tried restarting my localhost, but that didn't make a difference and running both of the following commands, neither of which seem to change anything:
基本上，我不知道发生了什么。我可以说我没有使用本地 Laravel 身份验证，所以我不确定这是否重要，但我觉得不应该。此外，我尝试重新启动我的本地主机，但这并没有产生任何区别并运行以下两个命令，这两个命令似乎都没有改变任何东西：
php artisan config:clear
php artisan route:clear
Lastly, I tried adding use Sessionat the top of the controller, but that doesn't seem to matter either.
最后，我尝试use Session在控制器顶部添加，但这似乎也无关紧要。
Basically, I don't know what to do. What could possibly be causing this? Thank you.
基本上，我不知道该怎么办。什么可能导致这种情况？谢谢你。

What's happening here is that when you add this:
这里发生的事情是，当您添加此内容时：
session(['test', 'x'])
It adds testat the 0thindex of the session and xat 1st. Now when you again do a
它在会话的第 0 个索引处添加test，在1st处添加x。现在当你再次做一个
session(['test1', 'xx'])它覆盖了 0th0和1st具有新值的会话的第一个索引。因此，当您打印会话数据时，您将获得最后一个值。您可以通过执行 a
dd(session()->all())dd(session()->all())并在屏幕上看到相同的内容来检查这一点。如果您想建立键值关系并将数据存储在这样的地方，请使用如下语法：session(['test' => 'x']);
session(['test1' => 'xx']);

Laravel 5.7 - store value in session with File system:
Laravel 5.7 - 在与文件系统的会话中存储值：
Set the value in session:
在会话中设置值：
session()->put('email', '[email protected]');
Get the value from session:
从会话中获取值：
$email = session()->get('email');
Delete the session of email:
删除电子邮件会话：
session()->forget('email');
It works like charm :)
它的作用就像魅力:)

In this case, all you need to do is add a "web" middleware chain function to your route rule. e.g
在这种情况下，您需要做的就是在路由规则中添加一个“web”中间件链函数。例如
Route::get('/some_path', 'SomeController@index')->middleware('web');
Then clear cache:
然后清除缓存：
php artisan config:clear
php artisan route:clear
