You can try with Session::pull('key');
你可以试试 Session::pull('key');
And if you want to delete all sessions variable you can use Session::flush();
如果你想删除所有会话变量，你可以使用 Session::flush();

Session::forget()does not return true/false. You can just remove your ifstatement.
Session::forget()不返回真/假。您可以删除您的if声明。
As a side note, if you're only using the userkey in Sessionfor storing the currently logged in user, you can just use Auth::user()instead.
附带说明一下，如果您仅使用user密钥Session来存储当前登录的用户，则可以Auth::user()改为使用。

You can use the Requestparameter, containing the current session. This way you can delete any session value by the key:
您可以使用Request包含当前会话的参数。这样您就可以通过键删除任何会话值：
use Illuminate\Http\Request;
Route::get('/logout', function(Request $request) {
//Uncomment to see the logs record
//\Log::info("Session before: ".print_r($request->session()->all(), true));
if ($request->session()->has('key')) {
$request->session()->forget('key');
}
//Uncomment to see the logs record
//\Log::info("Session after: ".print_r($request->session()->all(), true));
return redirect('/');
});
Or you can delete all values in the session:
或者您可以删除会话中的所有值：
use Illuminate\Http\Request;
Route::get('/logout', function(Request $request) {
//Uncomment to see the logs record
//\Log::info("Session before: ".print_r($request->session()->all(), true));
$request->session()->flush();
//Uncomment to see the logs record
//\Log::info("Session after: ".print_r($request->session()->all(), true));
return redirect('/');
});

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class StudentRecord extends Controller
{
public function logout(Request $req)
{
if($req-session()->has('key'){
$req->session()->forget('key');
return redirect('/');
}
//Or simple
public function logout(Request $req)
{
//if($req-session()->has('key')
$req->session()->flush();
}
}
//Then Do this in your route file
Route:get("/logout",StudentRecord@logout);
<a href=" {{ url(logout)}}">logout</a>
