我有供应商提供的Web服务;特定操作的WSDL如下所示:
<complexType name="ArrayOf_soapenc_string">
<complexContent>
<restriction base="soapenc:Array">
<attribute ref="soapenc:arrayType" wsdl:arrayType="soapenc:string[]"/>
</restriction>
</complexContent>
</complexType>
...
<wsdl:message name="initExportDeviceRequest">
<wsdl:part name="filter" type="soapenc:string"/>
<wsdl:part name="options" type="impl:ArrayOf_soapenc_string"/>
</wsdl:message>
...
<wsdl:operation name="initExportDevice" parameterOrder="filter options">
<wsdl:input message="impl:initExportDeviceRequest" name="initExportDeviceRequest"/>
<wsdl:output message="impl:initExportDeviceResponse" name="initExportDeviceResponse"/>
</wsdl:operation>
在WSDL上运行
python -mzeep ipam_export.wsdl
会产生以下结果:Global types:
ns0:ArrayOf_soapenc_string(_value_1: string[], arrayType: xsd:string, offset: ns1:arrayCoordinate, id: xsd:ID, href: xsd:anyURI, _attr_1: {})
...
Service: ExportsService
Port: Exports (Soap11Binding: {http://diamondip.com/netcontrol/ws/}ExportsSoapBinding)
Operations:
...
initExportDevice(filter: ns1:string, options: {_value_1: string[], arrayType: xsd:string, offset: ns1:arrayCoordinate, id: xsd:ID, href: xsd:anyURI, _attr_1: {}}) -> initExportDeviceReturn: ns2:WSContext
我在执行initExportDevice调用(特别是
options
参数)时遇到困难。How to use a complex type from a WSDL with zeep in Python建议我这样做:
filter_type=client.get_type('ns1:string')
filter=filter_type('addrType=4')
options_type=client.get_type('ns0:ArrayOf_soapenc_string')
options=options_type(['recurseContainerHierarchy'])
client.service.initExportDevice(filter, options)
但它引发了一个异常(exception)
Any element received object of type 'str', expected lxml.etree._Element or zeep.objects.string
See http://docs.python-zeep.org/en/master/datastructures.html#any-objects for more information
任何
options_type=client.get_type('ns0:ArrayOf_soapenc_string')
options=options_type('recurseContainerHierarchy')
client.service.initExportDevice(filter, options)
或者
factory = client.type_factory('ns0')
options=factory.ArrayOf_soapenc_string(['recurseContainerHierarchy'])
client.service.initExportDevice(filter=filter, options=options)
或者
factory = client.type_factory('ns0')
options=factory.ArrayOf_soapenc_string('recurseContainerHierarchy')
client.service.initExportDevice(filter=filter, options=options)
或者
factory = client.type_factory('ns0')
options=factory.ArrayOf_soapenc_string(_value_1=['recurseContainerHierarchy'])
client.service.initExportDevice(filter=filter, options=options)
都引发相同的异常
options_type=client.get_type('ns0:ArrayOf_soapenc_string')
options=xsd.AnyObject(options_type, ['recurseContainerHierarchy'])
client.service.initExportDevice(filter, options)
产量
argument of type 'AnyObject' is not iterable
如何构造此参数?
最佳答案
好的,所以我在使用Zeep时也遇到了麻烦(很容易使用suds),问题是Zeep将数组作为函数返回(根据我的测试),因此您需要将函数分配给数组,然后对其进行修改。从您当前的代码来看,好像您是将数据直接传递给该函数(该函数不会存储数据)。
使用上面的示例,下面的示例应检索Array类型,并允许您将其修改为有效的数据类型。
emptyArrayPlaceholder = client.get_type('ns0:ArrayOf_soapenc_string')
然后,Zeep将这种类型作为函数返回,因此首先您需要将此函数分配给变量,例如:
options = emptyArrayPlaceholder()
如果随后要检查选项,您将看到它是字典,其中包含列表。
print (options)
{'soapenc': []}
然后,您可以使用以下命令轻松地将项目添加到数组中:
options['soapenc'].append('Foo')
然后,您应该可以向您的客户提交
client.service.initExportDevice(filter, options)
作为选项,现在是有效的Zeep数据类型。
