MERN项目集成Razorpay支付网关时UPI选项缺失问题求助

我在MERN栈项目中集成Razorpay支付网关时遇到问题：支付界面仅显示银行卡、网银、钱包、先买后付选项，UPI选项完全不显示。以下是项目相关代码，希望有人能帮忙排查解决。

• 截图1：支付界面仅展示银行卡、网银、钱包、先买后付四种支付方式
• 截图2：支付方式展开详情，无任何UPI相关选项

server.js 后端代码 #

router.post("/checkout", async (req, res) => {
  try {
    const { totalPrice } = req.body;
    const { totalprice } = totalPrice;
    const amount = totalprice; // 转换为最小货币单位（如派萨）
    console.log('Request Body:', req.body);
    console.log('Total Amount:', totalprice);
    console.log('Amount in paisa:', amount); // 打印转换后的金额

      // 创建支付订单
      const options = {
          amount, // 订单金额（最小货币单位）
          currency: "INR",
          receipt: "receipt#1",
          payment_capture: 1,
      };
      const order = await instance.orders.create(options);
      console.log(order);
      res.status(200).json({ success: true, order });
  } catch (error) {
      console.error('Error during checkout:', error);
      res.status(500).json({ success: false, error: 'Error during checkout' });
  }
});

// 支付验证接口
router.post("/paymentverification", async (req, res) => {
  try {
      const { razorpay_order_id, razorpay_payment_id, razorpay_signature } = req.body;
      const body = razorpay_order_id + "|" + razorpay_payment_id;
      const expectedSignature = crypto.createHash('sha256', process.env.RAZORPAY_API_SECRET)
          .update(body.toString())
          .digest('hex');
      const isAuthentic = expectedSignature === razorpay_signature;
      if (isAuthentic) {
          await razorpayment.create({ razorpay_order_id, razorpay_payment_id, razorpay_signature });
          res.redirect(`http://localhost:3000/success?reference=${razorpay_payment_id}`);
      } else {
          res.status(400).json({ success: false, message: 'Invalid signature' });
      }
  } catch (error) {
      console.error('Error during payment verification:', error);
      res.status(500).json({ success: false, error: 'Error during payment verification' });
  }
});

router.get("/api/getkey", (req, res) => {
  return res.status(200).json({ key: process.env.RAZORPAY_API_KEY });
});

checkout.js（React前端）代码 #

const checkouthandler = async (totalPrice) => {
    try {
      console.log('Total Price:', totalPrice); // 打印订单总价

        // 获取Razorpay密钥
        const { data: { key } } = await axios.get("http://localhost:5000/api/getkey");

        // 创建支付订单
        const { data: { order } } = await axios.post("http://localhost:5000/checkout", { totalPrice });

        // 配置支付选项
        const options = {
            key,
            totalprice: order.totalprice,
            currency: "INR",
            payment_method: 'upi',
            name: "Sinmplyjs",
            description: "Razorpay tutorials",
            image: "",
            order_id: order.id,
            
            callback_url: 'http://localhost:5000/paymentverification',
            prefill: {
                name: "raj gupta",
                email: "raj@gmail.com",
                contact: "1234567890"
            },
            notes: {
                "address": "razorpay official"
            },
            theme: {
                "color": "#3399cc"
            }
        };

        // 初始化Razorpay并打开支付弹窗
        const razorpay = new window.Razorpay(options);
        razorpay.open();
    } catch (error) {
        console.error('Error during checkout:', error);
        // 错误处理
    }
}
