我尝试在条带端连接并创建帐户，但出现错误：
未提供API密钥。在构造StripeClient示例时设置API密钥，或者使用$opts参数中的api_key密钥在每个请求的基础上提供它。
我的控制器

应用服务提供者

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Schema;
use Carbon;
use Stripe\StripeCLient;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {
        $this->app->singleton(StripeClient::class, function(){
            return new StripeClient(config('stripe.secret'));
           });
    }

    /**
     * Bootstrap any application services.
     */
    public function boot(): void
    {
       $this->app->singleton(StripeClient::class, function(){
        return new StripeClient(config('stripe.secret'));
       });
    }
}

如何修复此错误？我想我必须注入修改一些关于StripeClient没有？
