使用StripeClient时出现错误:未提供API密钥。

import stripe

stripe.api_key = 'your_stripe_api_key'

import com.stripe.Stripe;
import com.stripe.model.Charge;

public class Main {
    public static void main(String[] args) {
        Stripe.apiKey = "your_stripe_api_key";
    }
}

const stripe = require('stripe')('your_stripe_api_key');

using Stripe;

StripeConfiguration.ApiKey = "your_stripe_api_key";

require_once 'vendor/autoload.php';

\Stripe\Stripe::setApiKey('your_stripe_api.js');
