[英]How to integrate paypal rest api in spring JPA application. ERROR CODE 400
根據這里提供的java SDK,我創建了一個新項目並嘗試集成代碼以進行paypal api調用。 但是當我運行應用程序時,它給出了我的錯誤: -
Error code : 401 with response : Server returned HTTP response code: 401 for URL: https://api.sandbox.paypal.com/v1/payments/payment
這是我的控制器類
package com.main.controller;
public class PaymentController{
@RequestMapping(method = RequestMethod.POST, produces = "application/JSON")
public Payment getString(){
InputStream is = PaymentController.class
.getResourceAsStream("/sdk_config.properties");
try {
PayPalResource.initConfig(is);
System.out.println("initiialization done");
} catch (PayPalRESTException e) {
System.out.println("Paypal Rest Exception : " + e.getMessage());
}
Map<String, String > map = new HashMap<String, String>();
map.put("mode", "sandbox");
String clientID = "AYDNebhrsuqiUKPU_ab-tCvGGVkzaxw2y4bIJFIl4rMuCW..........................";
String clientSecret="ENgjkFRgy1yGhal0aobwdF8kLNglkDaDeDItLN-lgQJZV4W1FpNQ27g3FC...............";
try {
accessToken = new OAuthTokenCredential(clientID, clientSecret,map).getAccessToken();
} catch (PayPalRESTException e) {
// TODO Auto-generated catch block
System.out.println("Cannot make the OAuthentication :" + e.getMessage());
}
Payment payment = createPayment();
return payment;
}
public Payment createPayment(){
Address billingAddress = new Address();
billingAddress.setCity("Johnstown");
billingAddress.setCountryCode("US");
billingAddress.setLine1("52 N Main ST");
billingAddress.setPostalCode("43210");
billingAddress.setState("OH");
CreditCard creditCard = new CreditCard();
creditCard.setBillingAddress(billingAddress);
creditCard.setCvv2(111);
creditCard.setExpireMonth(11);
creditCard.setExpireYear(2018);
creditCard.setFirstName("Joe");
creditCard.setLastName("Shopper");
creditCard.setNumber("5500005555555559");
creditCard.setType("mastercard");
Details details = new Details();
details.setShipping("1");
details.setSubtotal("5");
details.setTax("1");
Amount amount = new Amount();
amount.setCurrency("USD");
amount.setTotal("7");
amount.setDetails(details);
Transaction transaction = new Transaction();
transaction.setAmount(amount);
transaction
.setDescription("This is the payment transaction description.");
List<Transaction> transactions = new ArrayList<Transaction>();
transactions.add(transaction);
FundingInstrument fundingInstrument = new FundingInstrument();
fundingInstrument.setCreditCard(creditCard);
List<FundingInstrument> fundingInstrumentList = new ArrayList<FundingInstrument>();
fundingInstrumentList.add(fundingInstrument);
Payer payer = new Payer();
payer.setFundingInstruments(fundingInstrumentList);
payer.setPaymentMethod("credit_card");
Payment payment = new Payment();
payment.setIntent("sale");
payment.setPayer(payer);
payment.setTransactions(transactions);
Payment createdPayment = null;
try {
String accessToken = GenerateAccessToken.getAccessToken();
String realAccessToken = "A101.kPIsO7eGXhg420XIjnZmPboCS27CeDF6TZjVfGR31f6ja1IotK3e6U-E_k9MwOO5.....";
/*
* String requestId = Long.toString(System.nanoTime(); APIContext
* apiContext = new APIContext(accessToken, requestId ));
*/
createdPayment = payment.create(apiContext);
System.out.println("Created payment with id = " + createdPayment.getId()
+ " and status = " + createdPayment.getState());
} catch (PayPalRESTException e) {
System.out.println("Cannot make the payment from here: " + e.getMessage());
}
return createdPayment;
}
}
更新: - 我添加了client_id
和secret
身份驗證憑據,現在我得到的是400
錯誤,即Validation Error
401未經授權。 因此,首先您必須授權並創建授權令牌。 以下是如何創建第一個呼叫的示例。
使用應用程序的OAuth密鑰進行/ token調用以獲取基本身份驗證值(密鑰是client_id和secret的值)。 在請求正文中,將grant_type設置為client_credentials。 運行該命令時,PayPal會生成並返回一個新的訪問令牌。
將您的令牌添加到您要創建的付款中。
請查看此示例中的以下行: https : //github.com/paypal/PayPal-Java-SDK/blob/master/rest-api-sample/src/main/java/com/paypal/api/sample/FuturePaymentSample。 Java的#L62
所以使用Sandbox之類的東西:
Map<String, String> configurationMap = new HashMap<String, String>();
configurationMap.put("mode", "sandbox");
APIContext apiContext = new APIContext();
apiContext.setConfigurationMap(configurationMap);
tokeninfo = Tokeninfo.createFromAuthorizationCodeForFpp(apiContext, params);
tokeninfo.setAccessToken(tokeninfo.getTokenType() + " " + tokeninfo.getAccessToken());
之后,您應該能夠調用tokeninfo.getAccessToken()來創建付款。
