我正在使用 Laravel 作為支付網(wǎng)關(guān)。對于支付網(wǎng)關(guān)，我使用 Stripe。當(dāng)我運行這段代碼時，它會告訴我：沒有這樣的計劃：1 個錯誤控制器：public function create(Request $request, Plan $plan)    {        if($request->user()->subscribedToPlan($plan->stripe_plan, 'main')) {            return redirect()->route('home')->with('success', 'You have already subscribed the plan');        }        $plan = Plan::findOrFail($request->get('plan'));        $stripeToken = $request->stripeToken;        $user = $request->user();        $stripeplan = $request->stripe_plan;        $planid = $request->plan;        $user->newSubscription($stripeplan, $planid)->create($stripeToken, [ ]);        return redirect()->route('home')->with('success', 'Your plan subscribed successfully');    }
