[使用BinarySecurityToken的Python符号SOAP请求

问题描述 投票：62回答：1

我正在尝试使用python使用证书签署SOAP请求。我尝试了py-wsse和python-zeep及其Signature方法和suds。两者都没有给我预期的结果。

Zeep给我：

Python中有没有一种简单的方法可以用BinarySecurityToken对SOAP信封进行签名？第一个和最后一个信封之间是否有适当的区别，还是都有效？

Chicklat及其API提供了两个示例（请参见底部）来解决此问题。第一个使用SecurityTokenReference签名证书，第二个使用BinaryTokenReference签名。您不必依赖于此API（因为它需要支付许可证费用），但是通过理解这样做的方式和使用自定义方法，这些都是获得预期结果的良好起点。

在第一个示例中：

  • （＃1）已加载SOAP XML模板，这是将使用pfx证书和BinarySecurityToken签名的模板；
  • （＃2-3）pfx，包含受密码保护的证书及其私钥的单个文件，然后通过提供密码作为输入来提取其私钥及其内部证书，是颁发证书时使用的密码；
  • （＃4）一旦从pfx文件中提取了证书，它就会被BASE64编码。在XML模板内部，此字符串将BASE64_CERT替换为提供给wsse：BinarySecurityToken;的值。
  • （＃5）构建wsse：SecurityTokenReference XML。此XML是KeyInfo，a storage to contain your certificate private key, used to verify the signature;
  • （＃6）使用Chicklat XML Digital Signature Generator签名XML。

您可以通过进行以下修改来使用第二个示例来适应第一个示例：

  • 更改sbXml的构造方式。例2从chilkat.CkXml()开始，展示了一种方法和设置参数。输出XML结构类似于使用BinarySecurityToken的此架构：

  • 您可以使用OpenSSL.crypto管理提取私钥和证书的pfx文件；

  • 您可以将SignXML用于生成XML Digital Signature。

from lxml import etree
from signxml import XMLSigner, XMLVerifier

data_to_sign = "<Test/>" // Your XML
root = etree.fromstring(data_to_sign)
signed_root = XMLSigner().sign(root, key=PRIVATE_KEY, cert=CERTIFICATE)
verified_data = XMLVerifier().verify(signed_root).signed_xml

参考示例：

示例1：Sign SOAP XML using a wsse:SecurityTokenReference

示例2：Sign with BinarySecurityToken
