python - Zeep 发送缺少强制标签的请求

Question

我的 SOAP 服务将使用各种无效负载进行测试，以确认返回适当的响应。

在进行测试之前，我想对我的服务进行自己的测试。一些测试涉及删除必填字段。我想使用 zeep 模拟这些测试，但 zeep 不允许我发送请求，如果我想要的数据中不存在任何必填字段，就会给我一个 zeep.exceptions.ValidationError 错误发送。

我可以配置一些设置，以便 zeep 不会因缺少字段而引发错误并发送无效请求吗？

示例代码:

from zeep import Client
from datetime import datetime

wsdl_url = 'http://myservice.com/egservice?wsdl'

payload = {
    'ServiceType': 'EgService',
    'AvailabilityWindow': [
        {'StartDateTime': datetime.now(),
         'EndDateTime': datetime.now(),
         'Validation': 'VALID'}],
    'Confirmation': 'Confirmed',
    'DateTimeStamp': datetime.now()
}  # N.B No ContractID included

soap_client = Client(wsdl_url)
operation = 'myExampleOperation'
with soap_client.settings(raw_response=True):
    response = soap_client.service[operation](**payload)

wsdl的相关部分:

<xs:complexType name="EgMessage">
    <xs:sequence>
        <xs:element name="ServiceType" type="tns:EgMessage_ServiceTypeType"/>
        <xs:element name="ContractID" type="tns:EgMessage_ContractIDType"/>
        <xs:element name="AUI" type="tns:EgMessage_AUIType" minOccurs="0"/>
        <xs:element name="AvailabilityWindow" type="tns:AvailabilityWindowType" maxOccurs="unbounded"/>
        <xs:element name="Confirmation" type="tns:EgMessage_ConfirmationType"/>
        <xs:element name="FileReason" type="tns:EgMessage_FileReasonType" minOccurs="0"/>
        <xs:element name="DateTimeStamp" type="xs:dateTime"/>
</xs:sequence>
</xs:complexType>

我遇到了同样的问题，然后找到了解决该问题的方法。有一个选项可以跳过必填字段的验证。您必须将要跳过的属性的值设置为 xsd.skipvalue。在您的场景中，将contractId的值设置为有效负载对象中的xsd.skipvalue

from zeep import xsd

payload = {
    'ServiceType': 'EgService',
    'ContractID':xsd.SkipValue,
    'AvailabilityWindow': [
        {'StartDateTime': datetime.now(),
         'EndDateTime': datetime.now(),
         'Validation': 'VALID'}],
    'Confirmation': 'Confirmed',
    'DateTimeStamp': datetime.now()
}
