Zeep:通过类型检查预先验证

例如,我有元素:

<element name="order_date" type="dateTime" minOccurs="1" maxOccurs="1"/>

'1.0' 对于那个领域,泽普仍然接受。以后我会明白 zeep.exceptions.Fault 因为SOAP服务器拒绝我的请求是因为这个错误的类型,因为它必须是ISO格式的日期

wsdl 归档 lxml 图书馆。这个很好用,但我不确定我是否正在使用 zeep 泽普

我目前的处理方法是:

# There are some missing variables, don't want to CP everything
from lxml import etree as ET

def get_xmlschema():
    wsdl_file = ...
    wsdl_tree = ET.fromstring(wsdl_file)
    return ET.XMLSchema(wsdl_tree.find('.//schema:schema', namespaces=NAMESPACES))


def prevalidate_soap_message(client, operation, *args, **kwargs):
    # zeep checks only required elements and doesn't perform type checking
    msg = client.create_message(client.service, operation, *args, **kwargs)
    payload = msg.find('*/')
    get_xmlschema().assertValid(payload)

这就是我发送有效载荷的方式:

client = zeep.Client(wsdl)
operation = client.service[operation_name]
payload = ... # this is python object with structure as in wsdl schema for that operation
result = operation(payload) # it raises ValidationError if elements are missing but not for types
