Laravel - How to get the guard that authenticated the user?
提问by Ricardo Carvalho
I have a customized LoginController with two functions:
我有一个自定义的 LoginController 有两个功能：
loginCustomer that runs Auth::guard('customer')->attempt(...);
loginEmployee that runs Auth::guard('employee')->attempt(...);
loginCustomer 运行 Auth::guard('customer')->attempt(...);
loginEmployee 运行 Auth::guard('employee')->attempt(...);
I have customized two guards in config.auth that points to my two Models (Customer and Employee) and protect the routes of backoffice and frontend.
我在 config.auth 中自定义了两个守卫，指向我的两个模型（客户和员工）并保护后台和前端的路由。
Now in my customized LogoutController i want to run Auth::logout() but it doesn't work because i think it uses the default guard.
现在在我自定义的 LogoutController 中，我想运行 Auth::logout() 但它不起作用，因为我认为它使用默认保护。
It only works if i specify Auth::guard('customer')->logout()or Auth::guard('employee')->logout(), depending the guard that was used to login.
它仅在我指定Auth::guard('customer')->logout()或时才有效Auth::guard('employee')->logout()，具体取决于用于登录的守卫。
Is there any way to get the guard used to authenticate the user so i can use only Auth::guard($guard)->logout?
有什么方法可以让警卫用来验证用户的身份，以便我只能使用Auth::guard($guard)->logout？

You can use shouldUsemethod:
您可以使用shouldUse方法：
After the call of this method you can logout user via guard you was previously set by shouldUsemethod.
调用此方法后，您可以通过之前通过shouldUse方法设置的守卫注销用户。
In your case:
在你的情况下：
if( Auth::guard('customer')->attempt(...) ){
Auth::shouldUse('customer');
}
if( Auth::guard('employee')->attempt(...) ){
Auth::shouldUse('employee');
}
After this you can use Auth::logout and previously choosen guard (via shouldUse) will be used:
在此之后，您可以使用 Auth::logout 并且shouldUse将使用先前选择的守卫（via ）：
// just use Auth::logout without Auth::guard(GUARDNAME)->logout()
Auth::logout();

This might not be the perfect solution, but it works. Basically, just go through all the guards and check if the user is authenticated by that guard. If he is - log him out. Be aware that this will log him out of all the guards he is logged in to.
这可能不是完美的解决方案，但它有效。基本上，只需通过所有警卫并检查用户是否已通过该警卫的身份验证。如果他是 - 将他注销。请注意，这会将他从他登录的所有守卫中注销。
This code would go to your logout controller:
此代码将转到您的注销控制器：
$guards = array_keys(config('auth.guards'));
foreach ($guards as $guard) {
if(Auth::guard($guard)->check()) Auth::guard($guard)->logout();
}
