Create optimal payment experiences for your customers by following these best practices for integrations.
Also, for user-presented mode In-store payment, we provide a reference implementation following these best practice. See com.alipay.ams.callbacks.UserPresentedCodePaymentCallback, com.alipay.ams.callbacks.PaymentInquiryCallback, com.alipay.ams.callbacks.PaymentCancelCallback and com.alipay.ams.job.JobExecutor for details.
//Enable the backend JobExecutor
{
JobExecutor.instance.setClient(AMS.with(cfg));
JobExecutor.instance.setJobSupport(jobSupport);
JobExecutor.instance.setPaymentInquiryCallback(paymentInquiryCallback);
JobExecutor.instance.startJobExecutor();
}
//Use UserPresentedCodePaymentCallback to handle all the underlying logic.
AMS.with(cfg)
.execute(request, new UserPresentedCodePaymentCallback(paymentInquiryCallback));We provide an API mocking tool(currently in BETA version) for you to easily test exceptional cases.
Below are some of the default out-of-box mocking rules that basically use the payment amount value to identify the desired mock response:
| API | when which input parameter | equals what | then you get a response of |
|---|---|---|---|
| ams/api/v1/payments/pay | payToAmount.value | 9901 | UNKNOWN_EXCEPTION |
| ams/api/v1/payments/pay | payToAmount.value | 9902 | network timeout |
| ams/api/v1/payments/inquiryPayment | payToAmount.value of the corresponding PAY request | 9903 | UNKNOWN_EXCEPTION |
| ams/api/v1/payments/inquiryPayment | payToAmount.value of the corresponding PAY request | 9904 | network timeout |
To use this mocking tool:
- Set gatewayUrl=https://isandbox.alipaydev.com
- Set alipayPublicKey to a fixed value that you can get from us through sandbox_service@alibaba-inc.com.
Pass all the acceptance test cases in the Alipay Developer Center to ensure a high quality integration. Especially, test exceptions by using test cases.
You can use whatever is your choice of HTTP client to initiate the requests by,
- Provide your own implementation of
com.alipay.ams.AMSClient, or - Using your own HTTP client that is totally irrelevant to
com.alipay.ams.AMSClient.
//To get the body content and http headers to be posted to AMS gateway
String body = request.buildBody().toString();
byte[] requestContent = body.getBytes("UTF-8");
RequestHeader requestHeader = request.buildRequestHeader();
//Now construct your specific HTTP request using requestContent as the body content and requestHeader as the HTTP headers.
//...
