具有nodeJs的条带网关

问题描述

我使用Stripe付款网关在项目中添加了付款选项，在用户模式模型中，我添加了isPaid（默认为布尔值var和false），成功付款后，我想将isPaid = true ，以下是我的index.js和checkout.js，但尝试实现req.user.isPaid = true;我或者无法访问此变量，或者在付款前该变量变为true。期待一些帮助

// // GET checkout
    
router.get('/checkout',middleware.isLoggedIn,(req,res) => {
    if (req.user.isPaid) {
        req.flash('success','Your account is already paid');
        return res.redirect('/students');
    }
    // payWithCard(stripe,card,data.clientSecret);
    res.render('checkout',{ amount: 100 });
});

const calculateOrderAmount = items => {
  
  return 100;
};
router.post("/create-payment-intent",async (req,res) => {
  const { items } = req.body;
  // Create a PaymentIntent with the order amount and currency
  try{
    const paymentIntent = await stripe.paymentIntents.create({
    amount: calculateOrderAmount(items),currency: "inr"
  });

  res.send({
    clientSecret: paymentIntent.client_secret
  });
    }
    catch(e){

    }
});

这是我的checkout.js

// checkout.js

    var stripe = Stripe(process.env.SecretKey);
    
    // The items the customer wants to buy
    var purchase = {
        items: [{ id: "Teacher Registration Fee" }],currency: "inr"
        };
    
    // disable the button until we have Stripe set up on the page
    document.querySelector("button").disabled = true;
    fetch("/create-payment-intent",{
      method: "POST",headers: {
        "Content-Type": "application/json"
      },body: JSON.stringify(purchase)
    })
      .then(function(result) {
        return result.json();
      })
      .then(function(data) {
        var elements = stripe.elements();
        var style = {
          base: {
            color: "#32325d",fontFamily: 'Arial,sans-serif',fontSmoothing: "antialiased",fontSize: "16px","::placeholder": {
              color: "#32325d"
            }
          },invalid: {
            fontFamily: 'Arial,color: "#fa755a",iconColor: "#fa755a"
          }
        };
        var card = elements.create("card",{ style: style });
        // Stripe injects an iframe into the DOM
        card.mount("#card-element");
        card.on("change",function (event) {
          // disable the Pay button if there are no card details in the Element
          document.querySelector("button").disabled = event.empty;
          document.querySelector("#card-error").textContent = event.error ? event.error.message : "";
        });
        var form = document.getElementById("payment-form");
        form.addEventListener("submit",function(event) {
          event.preventDefault();
          // Complete payment when the submit button is clicked
          payWithCard(stripe,data.clientSecret);
        });
      });
    // Calls stripe.confirmCardPayment
    // If the card requires authentication Stripe shows a pop-up modal to
    // prompt the user to enter authentication details without leaving your page.
    var payWithCard = function(stripe,clientSecret) {
      loading(true);
      stripe
        .confirmCardPayment(clientSecret,{
          payment_method: {
            card: card
          }
        })
        .then(function(result) {
          if (result.error) {
            // Show error to your customer
            showError(result.error.message);
          } else {
            // The payment succeeded!
            orderComplete(result.paymentIntent.id);
          }
        });
    };
    /* ------- UI helpers ------- */
    // Shows a success message when the payment is complete
    var orderComplete = function(paymentIntentId) {
      loading(false);
      document
        .querySelector(".result-message a")
        .setAttribute(
          "href","https://dashboard.stripe.com/test/payments/" + paymentIntentId
        );
      document.querySelector(".result-message").classList.remove("hidden");
      document.querySelector("button").disabled = true;
    };
    // Show the customer the error from Stripe if their card fails to charge
    var showError = function(errorMsgText) {
      loading(false);
      var errorMsg = document.querySelector("#card-error");
      errorMsg.textContent = errorMsgText;
      setTimeout(function() {
        errorMsg.textContent = "";
      },4000);
    };
    // Show a spinner on payment submission
    var loading = function(isLoading) {
      if (isLoading) {
        // disable the button and show a spinner
        document.querySelector("button").disabled = true;
        document.querySelector("#spinner").classList.remove("hidden");
        document.querySelector("#button-text").classList.add("hidden");
      } else {
        document.querySelector("button").disabled = false;
        document.querySelector("#spinner").classList.add("hidden");
        document.querySelector("#button-text").classList.remove("hidden");
