mastercard API 的问题，文档中未发现的错误

Question

我需要帮助，这是我的代码，下面是问题：

import requests
import json
from requests.auth import HTTPBasicAuth
from api_key_util_con import getAuthHeader, encrypt

BASE_URL = 'https://sandbox.api.mastercard.com/openapis/'

global card_ref

def postInitialApiRequest(request):
    global card_ref

    uri = f'{BASE_URL}authentication/consents'

    # Encrypt the request (using encryption key)
    encryptedRequest = encrypt(request)

    # Form json string
    encryptedRequestJson = json.dumps(encryptedRequest)

    # Create the OAuth signature for this request (using signing key)
    authHeader = getAuthHeader(uri, method='POST',
                               payload=encryptedRequestJson)

    # Headers - we need just authorization and content-type
    headers = {
        'Authorization' : authHeader,
        'Content-Type': 'application/json'
    }

    # Call the API
    response = requests.post(uri, headers=headers,
                             data=encryptedRequestJson, verify=False)
    print(f'Response: {response.text}')
    response_data = response.json()
    card_ref = response_data.get("cardReference")

    return card_ref, auth

def startAuthentication(card_ref, CardDetails):
    uri = f'{BASE_URL}authentication/consents/{card_ref}/start-authentication'

    # Encrypt the request (using encryption key)
    encryptedRequest = encrypt(CardDetails)
    # Form json string
    encryptedRequestJson = json.dumps(encryptedRequest)
    # Create the OAuth signature for this request (using signing key)
    authHeader = getAuthHeader(uri, method='POST', payload=encryptedRequestJson)

    # Headers - we need just authorization and content-type
    headers = {
        'Authorization': authHeader,
        'Content-Type': 'application/json'
    }

    try:
        # Call the API
        response = requests.post(uri, headers=headers,
                                 data=encryptedRequestJson, verify=False)

        # Log request and response details
        print(f'Request URI: {uri}')
        print(f'Response: {response.text}')

        return response.json()

    except Exception as e:
        print(f'Error: {e}')
        return None

测试卡数据：

testCardDetails = {
    "consents": [
        {
            "name": "notification",
            "details": {
                "businessName": "CorporateA"
            }
        }
    ],
    "cardDetails": {
        "pan": 5204730541001066,
        "expiryMonth": 1,
        "expiryYear": 2025,
        "cvc": 123,
        "cardholderName": "John"
    }
}

CardDetails = {
    "auth": {
        "type": "THREEDS",
        "params": {}
    },
    "cardDetails": {
        "pan": 5204730541001066,
        "expiryMonth": 1,
        "expiryYear": 2025,
        "cvc": 123,
        "cardholderName": "John"
    }
}

card_ref, auth = postInitialApiRequest(testCardDetails)
startAuthentication(card_ref, CardDetails)

在第二个函数中，出现了我在文档中未找到的错误：

响应：{“错误”：{“错误”：[{“源”：“CBC”，“reasonCode”：“rest.failed”，“描述”：“400 错误请求：[{“errorCode”：“4003 ","errorDetail":"3DS 方法 URL 可用","errorDescription":"3DS 方法完成指示器错误。在缓存中找到 3DS 方法 URL。","thirdDSServerTransID":"695d7429-8a27-4ce4-90d3-7ee2c37efe90","errorComponent":"S","messageVersion":"2.2.0"}]","可恢复": false,"详细信息":"0.a1054917.1705427566.ad3570"}]}}

我尝试将第一个函数的响应放入身份验证，但没有任何变化

1. 您在“pan”字段（/卡号）中使用整数，但它 可能预期为字符串。

2. 该错误表明在以下位置找到了 3D 安全方法 URL： 缓存。清除 3D 安全事务所在的缓存 已处理。

3. 验证您的 3D 安全配置（包括方法 URL）是 正确。

4. 确保配置符合您的规格 支付网关或卡处理器。
