我正在尝试将教皇与我的春季Web服务集成。我正在引用高级服务器集成并使用此SDK创建付款样本。
这是我的客户端代码
<script src="https://www.paypalobjects.com/api/checkout.js">
</script>
<h1>Paypal Integration - Advanced Server Side Integration</h1>
<div id="paypal-button-container"></div>
<script>
// Render the PayPal button
paypal.Button.render({
// Set your environment
env: 'sandbox', // sandbox | production
// Wait for the PayPal button to be clicked
payment: function() {
// Make a call to the merchant server to set up the payment
return paypal.request.post('http://localhost:8080/api/createpayment').then(function(res) {
console.log(res);
return res.payToken;
});
},
// Wait for the payment to be authorized by the customer
onAuthorize: function(data, actions) {
// Make a call to the merchant server to execute the payment
return paypal.request.post('http://localhost:8080/api/createpayment', {
payToken: data.paymentID,
payerId: data.payerID
}).then(function(res) {
console.log(res);
document.querySelector('#paypal-button-container').innerText = 'Payment Complete!';
});
}
}, '#paypal-button-container');
</script>
这是我的Web服务
@RequestMapping(value = "/createpayment", method = RequestMethod.POST)
public @ResponseBody
Payment createPayment(HttpServletRequest request, HttpServletResponse response) {
Map<String, String> map = new HashMap<String, String>();
Payment createdPayment = null;
try {
final String clientID = "<clientId>";
final String clientSecret = "clientSecret";
// ### Api Context
// Pass in a `ApiContext` object to authenticate
// the call and to send a unique request id
// (that ensures idempotency). The SDK generates
// a request id if you do not pass one explicitly.
APIContext apiContext = new APIContext(clientID, clientSecret, "sandbox");
if (request.getParameter("PayerID") != null) {
logger.info("Payment Execution");
Payment payment = new Payment();
if (request.getParameter("guid") != null) {

// Total must be equal to sum of shipping, tax and subtotal.
amount.setTotal("0.1");

// ###Transaction
// A transaction defines the contract of a

// ###Payer
// A resource representing a Payer that funds a payment
// Payment Method
// as 'paypal'
Payer payer = new Payer();

// A Payment Resource; create one using
// the above types and intent as 'sale'

+ request.getServerName() + ":" + request.getServerPort()
+ request.getContextPath() + "/paymentwithpaypal?guid=" + guid);
payment.setRedirectUrls(redirectUrls);
// Create a payment by posting to the APIService
// using a valid AccessToken
// The return object contains the status;
try {
createdPayment = payment.create(apiContext);
logger.info("Created payment with id = "
+ createdPayment.getId() + " and status = "
+ createdPayment.getState());
// ###Payment Approval Url
Iterator<Links> links = createdPayment.getLinks().iterator();
while (links.hasNext()) {
Links link = links.next();
if (link.getRel().equalsIgnoreCase("approval_url")) {
request.setAttribute("redirectURL", link.getHref());
}
}
//ResultPrinter.addResult(req, resp, "Payment with PayPal", Payment.getLastRequest(), Payment.getLastResponse(), null);
map.put(guid, createdPayment.getId());
} catch (PayPalRESTException e) {
e.printStackTrace();
//ResultPrinter.addResult(req, resp, "Payment with PayPal", Payment.getLastRequest(), null, e.getMessage());
}
}
} catch (Exception e) {
logger.error("Create Payment Exception ");
e.printStackTrace();
}
return createdPayment;
}
当我单击贝宝结帐按钮时。客户代码试图访问我的创建付款API http://localhost/api/createpayment。我得到的回应是403禁止。我试图使用Post Man Client访问此API，这很好。我无法弄清楚我身边出了什么问题。
问题可能来自您的弹簧正在运行的 port 。
另外，如果该请求是从另一个域完成的，请确保您有@Crossorigin注释。
@CrossOrigin
@RequestMapping(value = "/createpayment", method = RequestMethod.POST)
public @ResponseBody
Payment createPayment(HttpServletRequest request, HttpServletResponse response) {
.....
