Laravel Sanctum 检查用户是否有令牌

Question

I'm trying to log in the user and If this user has any token in the personal_access_tokens table remove them and create a new one. I tried it, but this throws me an error saying Call to a member function currentAccessToken() on null

Here is my code I used in my login method,

$request->validate([
    'email'    => 'required | email',
    'password' => 'required'
]);


$user = User::where('email', $request->email)->first();

if (!$user){
    return response(['payback' => 'Account not found']);
} else if(!Hash::check($request->password, $user->password)){
    return response(['payback' => 'Incorrect Credentials']);
}

if($request->user()->currentAccessToken()){
    $request->user()->currentAccessToken()->delete();
} else {
    return response(['payback' => 'Not Has Tokens']);
}

$token = $user->createToken('ribluma_access_token')->plainTextToken;

I tried a solution that works,

        $request->validate([
            'email'    => 'required | email',
            'password' => 'required'
        ]);


        $user = User::where('email', $request->email)->first();

        if (!$user) {
            return response(['payback' => 'Account not found']);
        } else if (!Hash::check($request->password, $user->password)) {
            return response(['payback' => 'Incorrect Credentials']);
        }

        if (count(DB::table('personal_access_tokens')->where('tokenable_id', $user->id)->get()) > 0) {
            DB::table('personal_access_tokens')->where('tokenable_id', $user->id)->delete();
        }

        $token = $user->createToken('ribluma_access_token')->plainTextToken;
        $response = [
            'user'  => $user,
            'token' => $token
        ];

        return $response;

This is the exact thing I want to do. But there should be a better way I guess. Really appreciate it if somebody could help thanks.

try this code for login

$request->validate([
    'email'    => 'required | email',
    'password' => 'required'
]);


$user = User::where('email', $request->email)->first();

if (!$user || !Hash::check($request->password, $user->password)) {
     return response(
        'message' => ['These credentials do not match our records.']
    ,404);
}

if(auth('sanctum')->check()){
    auth()->user()->tokens()->delete();
}

$token = $user->createToken('ribluma_access_token')->plainTextToken;
