關於Braintree支付網關和Java的集成

Question

我是支付網關集成的新手。我需要將Braintree Payment Gateway與JSF應用程序集成。有人可以展示我的java類和示例支付頁面的基本示例。我看到一些客戶端Token如何生成它。我寫了一個樣本類和頁面如下，但我coudnt作出我沒有得到的主意。

頁

<form id="checkout" method="post" action="/checkout"> 
    <div id="payment-form"></div> 
    <input type="submit" value="Pay $15"> 
</form> 

<script src="https://js.braintreegateway.com/v2/braintree.js"></script> 
<script> 
    // We generated a client token for you so you can test out this code 
    // immediately. In a production-ready integration, you will need to 
    // generate a client token on your server (see section below). 
    var clientToken = "sZWQiOmZhbHNlLCJtZXJjaGFudElkIjoiMzQ4cGs5Y2dmM2JneXcyYiIsInZlbm1vIjoib2ZmIn0="; 

    braintree.setup(clientToken, "dropin", { 
     container : "payment-form" 
    }); 

</script> 

類

import spark.Request; 
import spark.Response; 
import spark.Route; 

import com.braintreegateway.BraintreeGateway; 
import com.braintreegateway.Environment; 

public class BrainTreeController { 
    private static BraintreeGateway gateway = new BraintreeGateway(
       Environment.SANDBOX, 
       "your_merchant_id", 
       "your_public_key", 
       "your_private_key" 
      ); 
     post(new Route("/client_token") { 
      @Override 
      public Object handle(Request request, Response response) { 
      return gateway.clientToken().generate(); 
      } 
     }); 
} 

我拿到後

Syntax error on token "post", @ expected before this token

結帳從Braintree Java SDK Implementation下面的樣本誤差。根據要求將其整合到您的項目中：

public class BrainTreeImplementation { 

private static Logger logger = Logger.getLogger(BrainTreeImplementation.class.getName()); 

// Below are the Braintree sandbox credentials 
private static BraintreeGateway gateway = null; 
private static String publicKey = "YOUR_PUBLIC_KEY"; 
private static String privateKey = "YOUR_PRIVATE_KEY"; 
private static String merchantId= "YOUR_MERCHANT_ID"; 

public static void main(String[] args) { 
    // Initialize Braintree Connection 
    gateway = connectBraintreeGateway(); 
    braintreeProcessing(); 
} 

public static void braintreeProcessing() { 

    System.out.println(" ----- BrainTree Implementation Starts --- "); 

    // Generate client Token 
    String clientToken = generateClientToken(); 
    System.out.println(" Client Token : " +clientToken); 

    // Receive payment method nonce 
    String nonceFromTheClient = receivePaymentMethodNonce(); 

    // Do payment transactions 
    BigDecimal amount = new BigDecimal("5.10"); 
    doPaymentTransaction(nonceFromTheClient, amount); 
} 

// Connect to Braintree Gateway. 
public static BraintreeGateway connectBraintreeGateway() { 
    BraintreeGateway braintreeGateway = new BraintreeGateway(
      Environment.SANDBOX, merchantId, publicKey, privateKey); 
    return braintreeGateway; 
} 

// Make an endpoint which return client token. 
public static String generateClientToken() { 
    // client token will be generated at server side and return to client 
    String clientToken = gateway.clientToken().generate(); 
    return clientToken; 
} 

// Make an endpoint which receive payment method nonce from client and do payment. 
public static String receivePaymentMethodNonce() { 
    String nonceFromTheClient = "fake-valid-mastercard-nonce"; 
    return nonceFromTheClient; 
} 

// Make payment 
public void String doPaymentTransaction(String paymentMethodNonce, BigDecimal amount) { 

    TransactionRequest request = new TransactionRequest(); 
    request.amount(amount); 
    request.paymentMethodNonce(paymentMethodNonce); 

    CustomerRequest customerRequest = request.customer(); 
    customerRequest.email("cpatel@gmail.com"); 
    customerRequest.firstName("Chirag"); 
    customerRequest.lastName("Patel"); 

    TransactionOptionsRequest options = request.options(); 
    options.submitForSettlement(true); 

    // Done the transaction request 
    options.done(); 

    // Create transaction ... 
    Result<Transaction> result = gateway.transaction().sale(request); 
    boolean isSuccess = result.isSuccess(); 

    if (isSuccess) { 
     Transaction transaction = result.getTarget(); 
     displayTransactionInfo(transaction); 
    } else { 
     ValidationErrors errors = result.getErrors(); 
     validationError(errors); 
    } 
} 

private static void displayTransactionInfo(Transaction transaction) { 
    System.out.println(" ------ Transaction Info ------ "); 
    System.out.println(" Transaction Id : " +transaction.getId()); 
    System.out.println(" Processor Response Text : " +transaction.getProcessorResponseText()); 
} 

private static void validationError(ValidationErrors errors) { 
    List<ValidationError> error = errors.getAllDeepValidationErrors(); 
    for (ValidationError er : error) { 
     System.out.println(" error code : " + er.getCode()); 
     System.out.println(" error message : " + er.getMessage()); 
    } 
} 
}
