python - 在泡沫中添加一个属性

Question

我必须用 suds 和 Python 做 soap 请求

<soap:Body> 
    <registerOrder> 
        <order merchantOrderNumber="" description="" amount=""  currency=""  language=""  xmlns=""> 
             <returnUrl>http://mysafety.com</returnUrl> 
        </order> 
    </registerOrder> 
</soap:Body>

如何在registerOrder中添加一个属性？

一个更加动态的 MessagePlugin 版本是:

from suds.sax.attribute import Attribute
from suds.plugin import MessagePlugin

class _AttributePlugin(MessagePlugin):
    """
    Suds plug-in extending the method call with arbitrary attributes.
    """
    def __init__(self, **kwargs):
        self.kwargs = kwargs

    def marshalled(self, context):
        method = context.envelope.getChild('Body')[0]
        for key, item in self.kwargs.iteritems():
            method.attributes.append(Attribute(key, item))

用法:

client = Client(url)
# method 1
client.options.plugins = [_AttributePlugin(foo='bar')]
response = client.service.method1()
client.options.plugins = []
# method 2
response = client.service.method2()
