在Laravel 5.3中创建自定义重定向逻辑； 无法登录用户

Question

I wanted to do custom redirect logic upon logging in to my site. So I wrote this code

public function login()
{
    $user = //what do I put here?
    $this->guard()->login($user);
    $id = Auth::id();
    //dd($id);
    $rfid = DB::table('users')->where('id', $id)->value('reference_id');
    if ($rfid == null){
        dd($id);
        return redirect()->action('RedirectController@client');
    }
    else {
        //dd($rfid);
        return redirect()->action('RedirectController@employee');
    }
}

However my problem is that all it does is redirect. Which makes sense. The code I have there only manages the redirect, there is nothing there to actually log anyone in. So I did some researching and found

 $this->guard()->login($user);

As a way to log the user in. However I don't know what to define the variable $user as. I know this should work because I use it in a different place on my site, but it the $user variable that I use there wouldn't work here. So under the scenario of simply login in the user, what do put there in order to authorize the user as in our database, and then log them in?

If you look at Laravel 5.3 AuthenticatesUsers traits , you will understand how login works behind the scene.

you need to change your login method to use attempt instead of login as follows to work it accordingly.

public function login(Request $request)
{
 $user = //what do I put here?
 $this->guard()->attempt($this->credentials($request), $request->has('remember'));
 $id = Auth::id();
 //dd($id);
 $rfid = DB::table('users')->where('id', $id)->value('reference_id');
 if ($rfid == null){
     dd($id);
     return redirect()->action('RedirectController@client');
 }
 else {
     //dd($rfid);
     return redirect()->action('RedirectController@employee');
 }}

I recommend you to use it as I mentioned. If you still want to get $user value you can try out

$user = $this->guard()->user();

Though I haven't used it like that.
