如何重写Laravel中的方法

Question

订阅控制器

class SubscriptionController extends Controller
{
    public function create(Request $request, Plan $plan)
    {
        $plan = Plan::findOrFail($request->get('plan'));
        $stripeToken = $request->stripeToken;
        $user = $request->user();
        $stripeplan = $request->stripe_plan;
        $subs = Subscriptions::findOrFail($request->get('plan'));

        $planid = $request->plan;
        $user->newSubscription($user->name, $planid)->create($stripeToken);
        return redirect()->route('home')->with('success', 'Your plan subscribed successfully');
    }
}

收银员的SubscriptionBuilder

public function create($token = null, array $options = [])
{
    $customer = $this->getStripeCustomer($token, $options);

    $subscription = $customer->subscriptions->create($this->buildPayload());

    if (in_array($subscription->status, ['incomplete', 'incomplete_expired'])) {
        $subscription->cancel();

        throw SubscriptionCreationFailed::incomplete($subscription);
    }

    if ($this->skipTrial) {
        $trialEndsAt = null;
    } else {
        $trialEndsAt = $this->trialExpires;
    }

    return $this->owner->subscriptions()->create([
        'name' => $this->name,
        'stripe_id' => $subscription->id,
        'stripe_plan' => $this->plan,
        'quantity' => $this->quantity,
        'trial_ends_at' => $trialEndsAt,
        'ends_at' => null,
    ]);
}

现在我想覆盖创建控制器功能。我想使用控制器删除数量，试用期结束。请帮助我
