У меня есть конечная точка, где я хотел бы отправлять пользователям денежное вознаграждение за действия с использованием PayPal.Предоставляется пользовательская модель,
@Entity
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(name = "name")
@NotNull
@NotEmpty
private String name;
@Column(name = "countryName")
@NotNull
@NotEmpty
private String countryName;
@Column(name = "currencyName")
@NotNull
@NotEmpty
private String currencyName;
/*
* total steps is for the keepign the history of the user movement
* */
@Column(name = "totalSteps")
@Min(value = 0L, message = BIGGER_OR_EQUAL_TO_ZERO)
private int totalSteps;
/*
* current steps is for providing the user reward. We will need to set
* it to zero after processing the user paymentUsingPaypal
* */
@Column(name = "currentSteps")
@Min(value = 0L, message = BIGGER_OR_EQUAL_TO_ZERO)
private int currentSteps;
@OneToMany(mappedBy = "user", cascade = CascadeType.ALL, orphanRemoval = true)
private List<Reward> rewards = new ArrayList<>();
public User() {
}
public User(@NotNull @NotEmpty String name, @NotNull @NotEmpty String countryName) {
this.name = name;
this.countryName = countryName;
}
public User(@NotNull @NotEmpty String name, @NotNull @NotEmpty String countryName, @Min(value = 0L, message = "The value must be positive") int totalSteps) {
this.name = name;
this.countryName = countryName;
this.totalSteps = totalSteps;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCountryName() {
return countryName;
}
public String getCurrencyName() {
return currencyName;
}
public void setCurrencyName(String currencyName) {
this.currencyName = currencyName;
}
public void setCountryName(String countryName) {
this.countryName = countryName;
}
public int getTotalSteps() {
return totalSteps;
}
public void setTotalSteps(int totalSteps) {
this.totalSteps = totalSteps;
}
public int getCurrentSteps() {
return currentSteps;
}
public void setCurrentSteps(int currentSteps) {
this.currentSteps = currentSteps;
}
public List<Reward> getRewards() {
return rewards;
}
public void setRewards(List<Reward> rewards) {
this.rewards = rewards;
}
public void addReward(Reward reward) {
if (this.rewards == null){
this.rewards = new ArrayList<>();
}
this.rewards.add(reward);
}
// .....
}
Предоставляется конечная точка API,
@PostMapping("/make-paypal-payment")
public ResponseEntity<Map<String, Object>> paymentUsingPaypal(@RequestBody User user) {
String s = calculateReward(user.getId()).getBody();
JSONObject obj = new JSONObject(s);
/**
* we get the reward amount in the local currency
*/
try {
String reward = obj.get("reward").toString();
payPalClient.createPayment(reward, user.getCurrencyName());
} catch (Exception ex) {
return ResponseEntity.status(HttpStatus.NO_CONTENT).build();
}
/*
* create an unique payment ID for processing the reward payment to our users
* */
String paymentId = (java.util.UUID.randomUUID()).toString();
Map<String, Object> paymentCompletion = payPalClient.completePayment(paymentId);
/*
* the payment processing is not successful
* */
// this is the code I added later as the paymanet is processing
// if(paymentCompletion.size() == 0){
// return ResponseEntity.status(HttpStatus.NO_CONTENT).build();
//}
return ResponseEntity.status(HttpStatus.CREATED).contentType(MediaType.APPLICATION_JSON_UTF8).body(paymentCompletion);
}
У меня есть класс, который я использую для платежа с использованием PayPal,
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class PayPalClient {
/**
* create the payment using the reward amount and currency name
* for our users
*
* @param sum
* @param currencyName
* @return
*/
public Map<String, Object> createPayment(String sum, String currencyName) {
Map<String, Object> response = new HashMap<>();
Amount amount = new Amount();
amount.setCurrency(currencyName);
amount.setTotal(sum);
Transaction transaction = new Transaction();
transaction.setAmount(amount);
List<Transaction> transactions = new ArrayList<>();
transactions.add(transaction);
Payer payer = new Payer();
payer.setPaymentMethod("paypal");
Payment payment = new Payment();
payment.setIntent("buy");
payment.setPayer(payer);
payment.setTransactions(transactions);
RedirectUrls redirectUrls = new RedirectUrls();
redirectUrls.setCancelUrl("http://localhost:4200/cancel");
redirectUrls.setReturnUrl("http://localhost:4200/");
payment.setRedirectUrls(redirectUrls);
Payment createdPayment;
try {
String redirectUrl = "";
APIContext context = new APIContext(CLIENT_ID, SECRET, "sandbox");
createdPayment = payment.create(context);
if (createdPayment != null) {
List<Links> links = createdPayment.getLinks();
for (Links link : links) {
if (link.getRel().equals("approval_url")) {
redirectUrl = link.getHref();
break;
}
}
response.put("status", "success");
response.put("redirect_url", redirectUrl);
}
} catch (PayPalRESTException e) {
System.out.println("Error happened during paymentUsingPaypal creation!");
}
return response;
}
/**
* complete the payment to our users using an unique payment ID
* and return the response code for the success (or faliure)
*
* @param paymentId
* @return
*/
public Map<String, Object> completePayment(String paymentId) {
Map<String, Object> response = new HashMap();
Payment payment = new Payment();
payment.setId(paymentId);
PaymentExecution paymentExecution = new PaymentExecution();
paymentExecution.setPayerId("eTherapists");
try {
APIContext context = new APIContext(CLIENT_ID, SECRET, "sandbox");
Payment createdPayment = payment.execute(context, paymentExecution);
if (createdPayment != null) {
response.put("status", "success");
response.put("payment", createdPayment);
}
} catch (PayPalRESTException e) {
System.err.println(e.getDetails());
}
return response;
}
}
Когда я выполняю запрос cURL,
$ curl -i -X POST -H "Content-Type:application/json" -d "{ \"id\": \"1\", \"name\": \"Maria\", \"countryName\": \"Philippine \", \"currencyName\": \"PHP\"}" http://localhost:8080/api/v1/users//make-paypal-payment
я получаю ответ,
HTTP/1.1 201
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked
Date: Mon, 15 Apr 2019 11:54:05 GMT
Это то, что я понял из кода (ниже)из сеанса отладки,
catch (PayPalRESTException e) {
System.err.println(e.getDetails());
}
Вывод отладки,
response-code: 404 details: name: INVALID_RESOURCE_ID message: Requested resource ID was not found. details: null debug-id: db7821c6c369a information-link: https://developer.paypal.com/docs/api/payments/#errors
Ошибка ясно, что пользователь не существует INVALID_RESOURCE_ID.Как мне написать код, чтобы я мог его внутренне протестировать?У меня нет пользовательского банкомата, а просто развиваюсь.
Спасибо.
