两个月前我最后一次使用 Zatca 时，它运行正常。我使用 XML 进行了测试，完成了整个过程，一切似乎都正常。但从昨天开始，我尝试使用相同的代码和相同的 XML 进行登录，这向我抛出了这个错误。而且根本不工作
{“validationResults”：{“infoMessages”：[]，“warningMessages”：[]，“errorMessages”：[{“type”：“错误”，“code”：“无效发票哈希”，“类别":"INVOICE_HASHING_ERRORS","message":"发票哈希 API 正文与 XML 的（计算的）哈希不匹配","status":"ERROR"},{"type":"ERROR","code" :"XSD_ZATCA_INVALID","category":"XSD 验证","message":"架构验证失败；XML 不符合符合 ZATCA 规范的 UBL 2.1 标准","status":"ERROR"}],"status ":"错误"},"reportingStatus":null,"clearanceStatus":"NOT_CLEARED","qrSellertStatus":null,"qrBuyertStatus":null}
这是我用于模拟合规性的 XML

这是我用 python 进行的哈希计算
et = ET.parse('Final_invoice_as_XML.xml')
# # find the UUID element
uuid_element = et.find('.//cbc:UUID', namespaces={'cbc': 'urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2'})
hash_value = et.find('.//ds:DigestValue', namespaces={'ds': 'http://www.w3.org/2000/09/xmldsig#'})
# # extract the text value of the UUID element
uuid = uuid_element.text
hash_value = hash_value.text
final_XML_invoice = str(final_XML_invoice)
final_XML_invoice = bytes(final_XML_invoice, 'utf-8')
# Store the encoded invoice data in base64 format
encoded_invoice = base64.b64encode(final_XML_invoice).decode()
也请始终分享您的导入。您应该必须学习调试代码：
import xml.etree.ElementTree as ET
import base64
et = ET.parse('final_XML_invoice.xml')
# # find the UUID element
uuid_element = et.find('.//cbc:UUID', namespaces={'cbc': 'urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2'})
hash_value = et.find('.//ds:DigestValue', namespaces={'ds': 'http://www.w3.org/2000/09/xmldsig#'})
# # extract the text value of the UUID element
uuid = uuid_element.text
print(uuid)
hash_value = hash_value.text
final_XML_invoice = "final_XML_invoice"
final_XML_invoice = bytes(final_XML_invoice, 'utf-8')
# Store the encoded invoice data in base64 format
encoded_invoice = base64.b64encode(final_XML_invoice).decode()
print(encoded_invoice)
