In this example, an event handler is established for the
merchantvalidation
event. It uses the
fetch()
to send a request to its own server with an argument of the payment method's validation URL, obtained from the event's
validationURL
property. The merchant server should access the validation URL in accordance with the payment method documention. Typically, a client should not access the validation URL.
request.addEventListener("merchantvalidation", event => {
event.complete(async () => {
const merchantServerUrl = window.location.origin +
'/validate?url=' + encodeURIComponent(event.validationURL);
// get validation data, and complete validation;
return await fetch(merchantServerUrl).then(response => response.text());
}, false);
};
const response = await request.show();
How merchant server handles the validation depends on the server implementation and payment method documentation. The content delivered by the validation server is forwarded to the merchant server and is then returned from the
fetch()
call's fulfillment handler to the
complete()
method on the event. This response lets the payment handler know if the merchant is validated.
还可以使用
onmerchantvalidation
event handler property to set up the handler for this event:
request.onmerchantvalidation = event => {
event.complete(async () => {
const merchantServerUrl = window.location.origin +
'/validate?url=' + encodeURIComponent(event.validationURL);
// get validation data, and complete validation;
return await fetch(merchantServerUrl).then(response => response.text());
});
};
const response = await request.show();
