Laravel 5.8 Cashier 7订阅：在null

如何解决Laravel 5.8 Cashier 7订阅：在null

我无法订阅工作。我总是有同样的错误。我使用Laravel 5.8和Cashier7。我详细说明了代码和问题。

这是错误

Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_ERROR)
Call to a member function create() on null

这是POST数据

POST Data
_token  "5z6mnrUi64GcIy0EZzHVlDgw7EDBH1DqltVS0bJS"
restaurant_id   "11"
stripeToken "tok_1HjJgFDpQQHNsFmdAKgw2ST2"
stripeTokenType "card"
stripeEmail "[e-mail]"

错误似乎出在第204行上的文件“ \ vendor \ laravel \ cashier \ src \ SubscriptionBuilder.php”中：“ $ subscription = $ customer-> subscriptions-> create（$ this-> buildPayload（））; “

文件.env

STRIPE_KEY=Here I keep my keys

STRIPE_SECRET=Here I keep my keys

文件config / services.php

我使用了一个名为Restaurant的不同模型，而不是使用默认的User模型。默认情况下，我也尝试过用户模型，问题是相同的。

'stripe' => [
    'model' => App\Models\Restaurant::class,'key' => env('STRIPE_KEY'),'secret' => env('STRIPE_SECRET')
],

文件App \ Models \ Restaurant.php

我实现并使用Billable类。

    class Restaurant extends Model implements HasMedia
    {
        use Billable;
        use HasMediaTrait {
            getFirstMediaUrl as protected getFirstMediaUrlTrait;
        }

    public $table = 'restaurants';
...

文件数据库\迁移\ add_stripe_to_restaurants_table.php

public function up()
{
    Schema::table('restaurants',function (Blueprint $table) {
        $table->string('stripe_id')->nullable();
        $table->string('card_brand')->nullable();
        $table->string('card_last_four')->nullable();
        $table->timestamp('trial_ends_at')->nullable();
    });
}

文件数据库\迁移\ create_subscriptions_table.php

public function up()
{
    Schema::create('subscriptions',function (Blueprint $table) {
        $table->increments('id');
        $table->integer('restaurant_id');
        $table->string('name');
        $table->string('stripe_id');
        $table->string('stripe_plan');
        $table->integer('quantity');
        $table->timestamp('trial_ends_at')->nullable();
        $table->timestamp('ends_at')->nullable();
        $table->timestamps();
    });
}

文件路由\ web.php

Route::post('process-subscription','SubscriptionController@process_subscription');

文件资源\视图\餐厅\ edit.blade.php

<form id="silverPlan" action="{{ url('process-subscription') }}" method="POST">
    {{ csrf_field() }}
    <script

文件app \ controllers \ SubscriptionController.php

“付款”方法效果很好，我可以对个人付款进行罚款。但是问题出在“过程_订阅”方法上。

    <?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Stripe\Stripe;
use Stripe\Customer;
use Stripe\Charge;
use App\Models\Restaurant;

class SubscriptionController extends Controller
{
    public function payment(Request $request)
    {
        try {
            Stripe::setApiKey(config('services.stripe.secret'));
            $customer = Customer::create(array(
                'email' => $request->stripeEmail,'source' => $request->stripeToken
            ));
            $charge = Charge::create(array(
                'customer' => $customer->id,'amount' => 1990,'currency' => 'eur'
            ));
        return 'Cargo exitoso!';
        } catch (\Exception $ex) {
            return $ex->getMessage();
        }
    }

    public function process_subscription(Request $request)
    {
        try {
            Stripe::setApiKey(config('services.stripe.secret'));
            $user = Restaurant::find(11);
            $user->newSubscription('main','price_1Hj9QLDpQQHNsFmdASQGIYPB')->create($request->stripeToken);
            return 'Suscripción exitosa! Acabas de suscribirte al Plan Plata';
        } catch (\Exception $ex) {
            return $ex->getMessage();
        }
    }
}
