How do I use custom stripe form and then integration with 3D Security options using ASP.NET MVC?
回答1:
Custom Form Design using Razor/ Html
<div class="campagin_start content" style="max-width:100%">
<div class="cell example example2" id="">
<form>
<div class="row">
<div class="field">
<div id="example2-card-number" class="input empty"></div>
<label for="example2-card-number" data-tid="elements_examples.form.card_number_label">Card number</label>
<div class="baseline"></div>
</div>
</div>
<div class="row">
<div class="field half-width">
<div id="example2-card-expiry" class="input empty"></div>
<label for="example2-card-expiry" data-tid="elements_examples.form.card_expiry_label">Expiration</label>
<div class="baseline"></div>
</div>
<div class="field half-width">
<div id="example2-card-cvc" class="input empty"></div>
<label for="example2-card-cvc" data-tid="elements_examples.form.card_cvc_label">CVC</label>
<div class="baseline"></div>
</div>
</div>
<button id="card-button">@WebResources.Donate $@Model.budget</button>
<a href="#" class="btn btn-border mt-10" style="display: none;margin-top: 10px;margin-left: 15px;" id="canceltran"> Cancel</a>
</form>
<p id="payment-result"><!-- we'll pass the response from the server here --></p>
</div>
</div>
Script
var stripe = Stripe('@ViewBag.StripePublishKey');
var elementStyles = {
base: {
color: '#32325D',
fontWeight: 500,
fontFamily: 'Source Code Pro, Consolas, Menlo, monospace',
fontSize: '16px',
fontSmoothing: 'antialiased',
'::placeholder': {
color: '#CFD7DF',
},
':-webkit-autofill': {
color: '#e39f48',
},
},
invalid: {
color: '#E25950',
'::placeholder': {
color: '#FFCCA5',
},
},
};
var elementClasses = {
focus: 'focused',
empty: 'empty',
invalid: 'invalid',
};
var elements = stripe.elements({
fonts: [
{
cssSrc: 'https://fonts.googleapis.com/css?family=Source+Code+Pro',
},
],
// Stripe's examples are localized to specific languages, but if
// you wish to have Elements automatically detect your user's locale,
// use `locale: 'auto'` instead.
locale: window.__exampleLocale
});
var Id = @Html.Raw(Json.Encode(Model.Id)); // Get Id From Model
var cardNumber = elements.create('cardNumber', {
showIcon: true,
style: elementStyles,
classes: elementClasses,
});
cardNumber.mount('#example2-card-number');
var cardExpiry = elements.create('cardExpiry', {
style: elementStyles,
classes: elementClasses,
});
cardExpiry.mount('#example2-card-expiry');
var cardCvc = elements.create('cardCvc', {
style: elementStyles,
classes: elementClasses,
});
cardCvc.mount('#example2-card-cvc');
var formClass = '.example2';
var example = document.querySelector(formClass);
var form = example.querySelector('form');
var resultContainer = document.getElementById('payment-result');
// Payment Button Handle
form.addEventListener('submit', function (event) {
$('#AjaxLoader').show();
event.preventDefault();
resultContainer.textContent = "";
stripe.createPaymentMethod({
type: 'card',
card: cardNumber,
}).then(handlePaymentMethodResult);
});
function handlePaymentMethodResult(result) {
if (result.error) {
$('#AjaxLoader').hide();
$("#canceltran").show();
// An error happened when collecting card details, show it in the payment form
resultContainer.textContent = result.error.message;
} else {
// Otherwise send paymentMethod.id to your server
fetch('/cart/pay', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ PaymentMethodId: result.paymentMethod.id, Id: Id})
}).then(function (result) {
return result.json();
}).then(handleServerResponse);
}
}
function handleServerResponse(responseJson) {
if (responseJson.error) {
// An error happened when charging the card, show it in the payment form
resultContainer.textContent = responseJson.error;
$('#AjaxLoader').hide();
$("#canceltran").show();
} else if (responseJson.requiresAction) {
// Use Stripe.js to handle required card action
stripe.handleCardAction(
responseJson.clientSecret
).then(function (result) {
if (result.error) {
$('#AjaxLoader').hide();
resultContainer.textContent = result.error.message;
$("#canceltran").show();
// Show `result.error.message` in payment form
} else {
// The card action has been handled
// The PaymentIntent can be confirmed again on the server
fetch('/cart/pay', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ PaymentIntentId: result.paymentIntent.id, Id:Id })
}).then(function (confirmResult) {
return confirmResult.json();
}).then(handleServerResponse);
$('#AjaxLoader').hide();
}
});
}
else {
// Show a success message or Required action
}
}
Controller -In Constructor, you have to use your Stripe Credentials
public class CartController : ControllerBase
{
public CartController()
{
StripeConfiguration.ApiKey = YOUR API KEY; // Replace your API KEY here
}
string stripePublishKey = YOUR PUBLISHER KEY; // Replace your PUBLISHER KEY here
private class StripeDataReq
{
public string PaymentMethodId { get; set; }
public string PaymentIntentId { get; set; }
public string Id { get; set; }
}
public async Task<ActionResult> Pay(StripeDataReq stripeDataReq)
{
// From Id you can get the value
var cart = await Cart.Table.LookupAsync(stripeDataReq.Id);
// We set amount (amout*100) because here amount consider in cent (100 cent charge $1) so
var amount = cart.Budget * 100;
var email = ""; // Set Email Id for payment Receiver
var service = new PaymentIntentService();
PaymentIntent paymentIntent = null;
try
{
if (stripeDataReq.PaymentMethodId != null)
{
// Create the PaymentIntent
var options = new PaymentIntentCreateOptions
{
Description = cart.Desc,
PaymentMethod = stripeDataReq.PaymentMethodId,
//Shipping is not nessasery for every region this is useful for an Indian Standard
//Shipping = new ChargeShippingOptions
//{
// Name = giver.Name,
// Address = new AddressOptions
// {
// Line1 = "510 Townsend St",
// PostalCode = "98140",
// City = "San Francisco",
// State = "CA",
// Country = "US",
// },
//},
ReceiptEmail = email,
Amount = amount,
Currency = "usd",
Confirm = true,
//ErrorOnRequiresAction = true,
ConfirmationMethod = "manual",
};
paymentIntent = service.Create(options);
}
if (stripeDataReq.PaymentIntentId != null)
{
var confirmOptions = new PaymentIntentConfirmOptions { };
paymentIntent = service.Confirm(
stripeDataReq.PaymentIntentId,
confirmOptions
);
}
}
// StripeException handle all types of failure error and then return the message into FE
catch (StripeException e)
{
return Json(new { error = e.StripeError.Message });
}
TempData["Id"] = stripeDataReq.Id;
return await generatePaymentResponse(paymentIntent);
}
//For 3D secure card
private async Task<ActionResult> generatePaymentResponse(PaymentIntent intent)
{
var CartId = TempData["Id"];
if (intent.Status.ToString().ToLower() == "succeeded")
{
// Handle post-payment fulfillment
return Json(new { success = true });
}
// requires_action means 3d secure card required more authentications for payment
else if (intent.Status == "requires_action")
{
// Tell the client to handle the action
return Json(new
{
requiresAction = true,
clientSecret = intent.ClientSecret
});
}
else
{
// Any other status would be unexpected, so error
return new HttpStatusCodeResult(HttpStatusCode.BadRequest, "Invalid PaymentIntent status");
}
}
}
