Laravel Lumen Call to undefined function App\Http\Controllers\back()
提问by wobsoriano
Hello so I am working on my own authentication system using Laravel's lumen and getting the error Call to undefined function App\Http\Controllers\back()whenever I try to login with wrong credentials. This what my function looks like in my controller:
您好，我正在使用 Laravel 的 lumen 开发我自己的身份验证系统，并且Call to undefined function App\Http\Controllers\back()每当我尝试使用错误的凭据登录时都会收到错误消息。这是我的函数在我的控制器中的样子：
public function loglink(Request $request) {
$input = $request->all();
$user = array(
'username' => $input['username'],
'password' => $input['password']
);
if (Auth::attempt($user)) {
$user = Auth::user();
return view('auth.welcome', compact('user'));
} else {
return back()->withInput();
}
}
Is there something I need to include/call in my controller?
我需要在控制器中包含/调用某些内容吗？

You can use back()shortland in Laravel only for now. For Lumen you need to add redirect():
您back()现在只能在 Laravel 中使用shortland。对于流明，您需要添加redirect()：
return redirect()->back()->withInput();
