Of course the docs tell us how to store session data*, but they don't address the OP's question regarding storing session data at login. You have a couple options but I think the clearest way is to override the AuthenticatesUsers trait's authenticated method.
当然，文档告诉我们如何存储会话数据*，但它们没有解决 OP 关于在登录时存储会话数据的问题。您有几个选择，但我认为最明确的方法是覆盖 AuthenticatesUsers 特征的身份验证方法。
Add the override to your LoginController:
将覆盖添加到您的 LoginController：
/**
* The user has been authenticated.
*
* @param \Illuminate\Http\Request $request
* @param mixed $user
* @return mixed
*/
protected function authenticated(Request $request, $user)
{
$this->setUserSession($user);
}
Then you can set your session up as:
然后您可以将会话设置为：
protected function setUserSession($user)
{
session(
[
'last_invoiced_at' => $user->settings->last_invoiced_at,
'total_amount_due' => $user->settings->total_amount_due
]
);
}
If you want to be a bit more clever you can create a listener for the Login or Authenticated events and set up the session when one of those events* fires.
如果您想更聪明一点，您可以为 Login 或 Authenticated 事件创建一个侦听器，并在这些事件之一触发时设置会话。
Create a listener such as SetUpUserSession:
创建一个侦听器，例如 SetUpUserSession：
<?php
namespace app\Listeners;
use Illuminate\Auth\Events\Login;
class SetUserSession
{
/**
* @param Login $event
* @return void
*/
public function handle(Login $event)
{
session(
[
'last_invoiced_at' => $event->user->settings->last_invoiced_at,
'total_amount_due' => $event->user->settings->total_amount_due
]
);
}
}
*Links go to 5.4 but this hasn't changed from 5.3.
*链接转到 5.4，但这与 5.3 没有变化。

I've used the Auth class to manage user data, like this:
我使用 Auth 类来管理用户数据，如下所示：
public function index(){
$user_id = Auth::user()->id;
}
But you have to add 'use Auth;' before class declaration. Then you can add any data to session variable.
但是您必须添加“使用身份验证；” 在类声明之前。然后您可以将任何数据添加到会话变量。

You can store data in the session using two different methods either a Request instance or using the global helper/function provided.
您可以使用两种不同的方法将数据存储在会话中，即请求实例或使用提供的全局帮助程序/函数。
Request Instance
请求实例
public function methodA(Request $request) {
$request->session()->put('KEY', 'VALUE');
}
Global Helper
全球帮手
public function methodB() {
session(['key' => 'value']);
}
You can find more details on both methods in the documentation.
您可以在文档中找到有关这两种方法的更多详细信息。
