Express JS 和 CoinPayments：无法获取 IPN 通知请求的请求正文

Question

所以这是我的问题，我使用 Express JS，我正在使用 coinPayments 设置支付，npm coinpayments 一切正常，但是我无法通过 IPN 获得任何主体

router.post(
  `/notify`,
  (req, res, next) => {
    res.send('ok');
    console.log('------------------------------ipn--------------------------------------');
    console.log('body', req.body);
    console.log('------------------------------ipn--------------------------------------');
    if (
      !req.get(`HMAC`) ||
      !req.body.ipn_mode ||
      req.body.ipn_mode !== `hmac` ||
      MERCHANT_ID !== req.body.merchant
    ) {
      return next(new Error(`Invalid request`));
    }

    let isValid;
    let error;

    try {
      isValid = verify(req.get(`HMAC`), IPN_SECRET, req.body);
    } catch (e) {
      error = e;
    }

    if (error && error) {
      return next(error);
    }

    if (!isValid) {
      return next(new Error(`Hmac calculation does not match`));
    }

    return next();
  }

我总是得到一个空的req.body

 ------------------------------ipn--------------------------------------
 body {}
 ------------------------------ipn--------------------------------------
Invalid request at router.post.txn_id.txn_id

有谁知道为什么，我该如何解决？

来自coinpayment documentation

It is implemented by making a standard HTTP POST (application/x-www-form-urlencoded) call over a https:// or http:// URL to a script or CGI program on your server.

在您的 Express 服务器中，您可能需要添加中间件来解析 urlencoded 格式的请求：

app.use(express.urlencoded({ extended: true })) // for parsing application/x-www-form-urlencoded
