Question

我们正在尝试在我们的项目中执行贝宝付款。我们使用了沙盒环境，并使用了paypal-rest-sdk并成功完成了付款。但是，我们尝试实施webhook，以便在连续付款后获得webhook响应/通知。我们实现了如下所示的webhooks，在成功端点被点击但响应为空之后，我们确实获得了webhooks的响应！

我们尝试了很多谷歌搜索和阅读文档，但都无济于事。如果那里的某个人以前使用paypal-rest-sdk做到了这一点，请帮助我们。

//webhooks.js

const paypal = require("paypal-rest-sdk");

let webhook_json = {
  url: "https://ac193954.ngrok.io/ewebhook",
  event_types: [
    {
      name: "PAYMENT.AUTHORIZATION.CREATED"
    },
    {
      name: "BILLING.SUBSCRIPTION.CREATED"
    },
    {
      name: "PAYMENT.CAPTURE.COMPLETED"
    }
  ]
};

let sync = async () => {
  return new Promise((resolve, reject) => {
    paypal.notification.webhook.create(webhook_json, function(error, webhook) {
      if (error) {
        reject(error);
      } else {
        resolve();
      }
    });
  });
};

module.exports = { paypalWebhook: sync };




//server.js

const { paypalWebhook } = require("./webhooks");

app.get("/success", (req, res) => {
    let paymentToken = req.query.token;
    paypal.billingAgreement.execute(paymentToken, {}, function(
      error,
      billingAgreement
    ) {
      if (error) {
        throw error;
      } else {
        console.log("Billing agreement", JSON.stringify(billingAgreement));
        let date = billingAgreement.start_date;
        let amountString =
          billingAgreement.plan.payment_definitions[1].amount.value;
        let trial =
          billingAgreement.plan.payment_definitions[0].frequency_interval;
        let frequencyInterval =
          billingAgreement.plan.payment_definitions[1].frequency_interval;
        let frequency = billingAgreement.plan.payment_definitions[1].frequency;
        let totalFrequency = frequencyInterval + " " + frequency;
        let period = [trial, totalFrequency];
        let amount = parseInt(amountString);
        try {
          Payment.create({
            id: uuidv1(),
            date: date,
            amount: amount,
            period: period
          });
        } catch (err) {
          throw new Error(err);
        }
        res.render("index");
      }
    });
  });

  app.get("/cancel", (req, res) =>
    res.send("Transaction cancelled please go back to the home page.")
  );

  try {
    let resultWebhook = await paypalWebhook();
    if (typeof resultWebhook == "Error") {
      return;
    }
    console.log("result", resultWebhook);
  } catch (err) {
    console.log("Webhook error", err);
  }

    //This route is being triggered about 5 seconds after the /success 
    route is triggered, but there are no any responses. 

  app.post("/ewebhook", (req, res) => {
    console.log("Webhook req res", req, res);
  });

这是执行/ success路由后对/ ewebhook的请求： https://gist.github.com/BikalNepal/4d2fd47063538d772c4432fa6d19c26d

以下是响应： https://gist.github.com/BikalNepal/4f09eb79e3204be624bef239f945d971

Paypal Webhooks没有发送任何响应
