Laravel Sanctum 檢查用戶是否有令牌

Question

我正在嘗試登錄用戶，如果此用戶在 personal_access_tokens 表中有任何令牌，請刪除它們並創建一個新令牌。 我試過了，但這會給我一個錯誤，說Call to a member function currentAccessToken() on null

這是我在登錄方法中使用的代碼，

$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;

我嘗試了一個可行的解決方案，

        $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;

這正是我想做的事情。 但我猜應該有更好的方法。 如果有人可以提供幫助，真的很感激。

試試這個代碼登錄

$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;
