res = urllib.request.urlopen(req)
print(res.read().decode('utf-8'))

headers = {'Content-Type': 'text/xml'}
若headers = {}
则Unsupported Content-Type: application/x-www-form-urlencoded
若headers = {'Content-Type': 'application/soap+xml; charset=utf-8'}
则Unsupported Content-Type: application/soap+xml; charset=utf-8

另外
The processing instruction target matching “[xX][mM][lL]” is not allowed
是因为content can't start with a space

输出结果:

问题:

那么, data_jaxws和data_spyne中的名字空间和参数名的值从哪里取呢?

  • 名字空间
    名字空间的值取自wsdl(如http://localhost:8000/?wsdl)的<definitions>或<wsdl:definitions>节点中xmlns:tns或targetNamespace的值
    如,

    1
    2
    xmlns:tns="spyne.examples.hello.soap"
    targetNamespace="spyne.examples.hello.soap"

  • 参数
    参数名取自wsdl的<wsdl:types>节点
    如,

    1
    2
    3
    4

    <wsdl:types>
        <xs:schema targetNamespace="spyne.examples.hello.soap" elementFormDefault="qualified">
            <xs:complexType name="stringArray">
                <xs:sequence>
                    <xs:element name="string" type="xs:string" minOccurs="0" maxOccurs="unbounded" nillable="true"/>
                </xs:sequence>

            ... ...
