如何解决如何使用 React Elements 在 Formik 向导中提交 Stripe Payment?
我正在使用 Formik 和 Material-UI 中的步进器在 React 中创建一个多步骤表单。那部分正在工作(终于!),我大致了解如何工作。第 1 步是账单地址,第 2 步是选择订阅计划,第 3 步是使用 Stripe 及其 CardElements 付款。这就是我偏离轨道的地方。
我在应用程序中加载了 Stripe,因此它被包装并可供我的表单使用。都好。我可以在单独测试时成功调用 Stripe 方法。
我的 Formik 外层在这里:
<Formik
{...props}
validationSchema={currentChild.props.validationSchema}
onSubmit={async (values,helpers) => {
if (isLastStep()) {
await props.onSubmit(values,helpers);
setCompleted(true);
} else {
setStep((s) => s + 1);
helpers.setTouched({});
if (step === 1) {
await props.getCustomerId(values.billingEmail);
}
}
}}
>
{... map over the steps,then the Back/Next/Submit buttons}
</Formik>
在 formStepper 创建时,我调用 useStripe()
和 useElements()
并创建一个 CardElement
,它被传递到第 3 步:
const stripe = useStripe();
const elements = useElements();
let stripeCard = CardElement;
<FormikStepper
initialValues={{ ...billingValues }}
onSubmit={(values,helpers) => {
createCustomer(values); //successfully sends formValues to be processed
}}
// I tried adding this here,but it isn't accessible inside the steps
// ETA: I put stripeProps inside the FormikStepper,which passes its properties down to the FormikStep inside. For non-Formik users,this works for the onBlur,onFocus,etc. as well as passing the initialValues. Basically,I was hoping the card element Could hitch a ride
stripeProps={{ card: stripeCard }}
getCustomerId={async (billingEmail) => {
await fetchCustomerId(billingEmail);
}}
>
<FormikStep
label="Billing Info"
validationSchema={object({ ...validationSchemaUsingYup })}
>
<Grid container item spacing={1}>
<CompanyProfile />
</Grid>
</FormikStep>
<FormikStep label="Choose Subscription">
<Grid container item spacing={1}>
<ChooseSubscription />
</Grid>
</FormikStep>
<FormikStep label="Review & Pay">
<Grid container item spacing={1}>
<StripePayment card={stripeCard} />
</Grid>
</FormikStep>
</FormikStepper>
在第 3 步中,我可以按预期呈现和使用 CardElement:
<props.card
options={{
style: {...styling}
}}
/>
我的困惑在于如何访问此元素以将数据提交给 Stripe??如何访问我传递到第 3 步的道具并使用它来处理付款?
我尝试将 Stripe 函数放在步骤 3 的函数中,但它们从未被调用,因为 onSubmit 函数位于步骤的父级上。我不能在不破坏使用条纹元素的安全方面的情况下将卡号放入 Formik initialValues。我能得到的最接近的就是这个错误:
Warning: An unhandled error was caught from submitForm() IntegrationError: A valid Element name must be provided. Valid Elements are:
card,cardNumber,cardExpiry,cardCvc,postalCode,paymentRequestButton,iban,idealBank,p24Bank,auBankAccount,fpxBank; you passed: object.
响应评论的更新:
stripeProps 尝试将信息打包到 FormikStepper
中,从而将 props 传递给子级 FormikStep
。
onSubmit
调用 createPaymentMethod
,如下所示:
async function createPaymentMethod(
values,stripeData = stripeCard,customer = customerId
) {
if (customer === undefined) {
customer = fetchCustomerId(values.billingEmail);
}
return stripe
.createPaymentMethod({
type: "card",card: elements.getElement(stripeData),//no errors with CardElement,but not sure that's the SAME element from the form
})
.then((result) => {
if (result.error) {
console.log(result.error);
} else {
createSubscription({
customer: customer,paymentMethodId: result.paymentMethod.id,items: [
{
price: values.TCPlan,quantity: values.TCPlanQuantity,},],});
}
})
.catch((err) => console.log(err));
}
// Step 2 of the Stripe process;
// Called if createPaymentMethod is error-free
function createSubscription({ customer,paymentMethodId,items }) {
console.log(customer,items);
let created = fetch(
"https://xxxxxx.amazonaws.com/xxx/xxxx",// My API Gateway endpoint
{
method: "post",headers: {
"Content-type": "application/json",body: JSON.stringify({
customerId: customer,paymentMethodId: paymentMethodId,priceId: items,}),}
);
created
.then((response) => {
console.log(response.json());
})
// varIoUs error-handling offered by Stripe...
}
