payfort "response_message"："带有标记化的无效命令

Question

我正在使用payfort进行支付过程

当向payfort api发送请求以给我一个token_name时，请求的响应使返回payfort"response_message":"Invalid command与TOKENIZATION

在payfort配置文件中激活商家页面通道，并设置其中的所有信息，如重定向链接和url等

并发送所有强制参数，签名成功，您可以在以下文档中看到请求参数

payfort文档

我正在使用spring boot并尝试从邮递员和角形式发送请求到我的api，然后在处理签名后重定向到payfortAPI

我正在使用测试url环境来测试来自payfort的交易

和我尝试发送请求从邮递员测试url环境从payfort不使用春季启动，但将返回相同的响应

和下面我的代码

@Data
public class Payment extends Signature implements ISignature{

private String expiry_date;
private String card_number;
private String card_security_code;
private String paymentSignature;
private String card_holder_name;
/*
public Payment(){
super();
}*/
public String getSignature(){
return paymentSignature;
}
public void setSignature() throws NoSuchAlgorithmException {
paymentSignature=createSign();
}
@Override
public String createSign() throws NoSuchAlgorithmException {
Map<String, Object> requestMap = new HashMap<>();
requestMap.put("service_command", this.getService_command());
requestMap.put("access_code", this.getAccess_code());
requestMap.put("merchant_identifier", this.getMerchant_identifier());
requestMap.put("merchant_reference", this.getMerchant_reference());
requestMap.put("language", this.getLanguage());
requestMap.put("expiry_date", this.getExpiry_date());
requestMap.put("card_number", this.getCard_number());
requestMap.put("card_security_code", this.getCard_security_code());
requestMap.put("card_holder_name",this.getCard_holder_name());
//order by key
requestMap = requestMap.entrySet().stream().sorted(Map.Entry.comparingByKey())
.collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue,
(oldValue, newValue) -> oldValue, LinkedHashMap::new));
String requestString = "saAbdalrhman0788&*";
for(Map.Entry<String, Object> entry: requestMap.entrySet())
requestString += entry.getKey() + "=" + entry.getValue();
requestString+= "Abdalrhman0788&*";
System.out.println("requestString = " + requestString);
MessageDigest digest = MessageDigest.getInstance("SHA-256");
byte[] hashed = digest.digest(requestString.getBytes(StandardCharsets.UTF_8));
String signature = javax.xml.bind.DatatypeConverter.printHexBinary(hashed);
System.out.println("signature = " + signature);
return signature;
}

这里是我调用payfort api的服务

public String CreateTokenization(Payment payment) throws NoSuchAlgorithmException, URISyntaxException {
fillTokenization(payment);
HttpHeaders headers = new HttpHeaders();
headers.set("Content-type", "application/json" );

Map<String,Object>  body=new HashMap<>();
body.put("service_command",payment.getService_command());
body.put("access_code",payment.getAccess_code());
body.put("merchant_identifier", payment.getMerchant_identifier());
body.put("merchant_reference", payment.getMerchant_reference());
body.put("expiry_date",payment.getExpiry_date());
body.put("card_number",payment.getCard_number());
body.put("card_security_code",payment.getCard_security_code());
body.put("signature",payment.getSignature());
// add request param before send the request to amazon payment api
URI uri = new URI(testEnvironment);
HttpEntity<Object> request = new HttpEntity<>(body, headers);
ResponseEntity<String> res= restTemplate.postForEntity(uri,request,String.class);
System.out.println("res = " + res.toString());
return res.toString();
}

，我将把这些数据发送给付款

{
"service_command":"TOKENIZATION",
"access_code":"LVQEEDAfI1qbZW0wXbsb",
"merchant_identifier":"5f803bfd",
"merchant_reference":"00658azx1",

"signature"35 d8d45435741d40619e947b0a8a7c8675bbd42fcb0c2bfc12c519cee48f3b3f"}

这是我从payfort

如果发送无效的符号将返回相同的响应

Answer 1

我发现签名错误，请删除以下行

requestMap.put("expiry_date", this.getExpiry_date());
requestMap.put("card_number", this.getCard_number());
requestMap.put("card_security_code", this.getCard_security_code());
requestMap.put("card_holder_name",this.getCard_holder_name());

因为我在payfort文档

中发现了这个注释

请记住-请不要在如果您使用的是自定义商家页面，则计算签名集成令牌化请求:card_security_code，卡号，过期日期，card_holder_name, memorber_me .

Answer 2

唯一需要的TOKENIZATION必须传递的参数为。

'service_command'     => 'TOKENIZATION',
'merchant_reference'  => your merchant Reference,
'access_code'         => your access code,
'merchant_identifier' => your merchant id,
'language'            => your preferred language in payment,
'return_url'          => your return url where you will get  response of payfort,

更进一步，你必须使用PURCHASE命令，如果前面的响应码为18000。
