如何在Java中使用Bitpay

import com.bitpay.sdk.BitPayException;
import com.bitpay.sdk.Client;
import com.bitpay.sdk.Env;
import com.bitpay.sdk.model.Invoice;
import com.bitpay.sdk.model.Item;
import com.bitpay.sdk.model.Currency;

public class BitpayExample {
    public static void main(String[] args) {
        // 设置API密钥和服务器环境
        String apiKey = "your_api_key";
        Env env = Env.TEST;

        // 创建Bitpay客户端对象
        Client bitpayClient = new Client(apiKey, env);

        try {
            // 创建一个新的发票
            Invoice invoice = new Invoice();
            invoice.setCurrency(Currency.USD);
            invoice.setPrice(10.0);
            invoice.setBuyerEmail("buyer@example.com");
            invoice.setNotificationURL("https://example.com/notification");

            Item item = new Item();
            item.setDescription("Product description");
            item.setPrice(10.0);
            item.setQuantity(1);
            invoice.setItem(item);

            // 发送发票请求并获取响应
            Invoice createdInvoice = bitpayClient.createInvoice(invoice);

            // 打印生成的发票ID和支付URL
            System.out.println("Invoice ID: " + createdInvoice.getId());
            System.out.println("Payment URL: " + createdInvoice.getUrl());
        } catch (BitPayException e) {
            e.printStackTrace();
        }
    }
}
