Question

我从这样的XML开始：

myXML="""<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:mes="http://www.ercot.com/schema/2007-06/nodal/ews/message">
  <soapenv:Header> </soapenv:Header>
  <soapenv:Body>
  <RequestMessage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.ercot.com/schema/2007-06/nodal/ews/message">

    </Request>
  </RequestMessage>
 </soapenv:Body>
</soapenv:Envelope>"""

我需要用它签名，所以看起来像这样

顺便说一句，那里的证书信息不是真实的，因此不用担心。

我从文档中查看了示例页面，但是我不知道它们的源xml是什么样的，因此这很难使我的用例成型。

Answer 1

围绕zeep，xmlsec的源代码进行了摸索，甚至尝试了lxml构造函数，但这是：

from zeep.wsse.signature import sign_envelope
from lxml import etree

raw_xml = open('unsigned-soapenv.xml').read()
xml_root_element = etree.fromstring(raw_xml)

signed = sign_envelope(
    xml_root_element,
    'rsakey.pem',
    'rsacert.pem'
)

tree = etree.ElementTree(xml_root_element)
tree.write('signed-soapenv.xml')

unsigned-soapenv.xml是您的信封。

如果您需要样本签名和证书，它们来自python-xmlsec's test data。

最有价值的是ipdb，它是具有自动完成功能的调试器。在您的终端中像这样尝试： import ipdb; ipdb.set_trace()

Answer 2

python-zeep软件包对WSSE初步支持-check out the documentation。

如何使用xmlsec（或其他更合适的软件包）对XML进行签名
