我在验证 SOAP 消息时间戳和正文时遇到问题。

在开始编写任何代码之前，我尝试自己验证它，这些是我验证时间戳所遵循的步骤：

1) 提取时间戳标签，添加任何使用的命名空间并将其写入文件：

<u:Timestamp u:Id="uuid-cd1febd3-a76a-4148-8a3e-367aee62293d-1" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
 <u:Created>2009-11-11T17:37:49.000Z</u:Created>
 <u:Expires>2009-11-11T17:42:49.000Z</u:Expires>
</u:Timestamp>

2) 使用 xmllint 对其进行规范化

xmllint --exc-c14n timestamp.xml > timestamp.ext-c14n.xml

3) 使用 openssl 获取文件的 SHA-1 摘要

openssl sha1 timestamp.ext-c14n.xml

4) uudecode 时间戳参考 (jGZkqCNLTnUfbdpoFn19LSYkhts=) 的 base64 DigestValue 并用十六进制编辑器打开

5) DigestValue 的二进制值与规范化 xml 片段的 sha1 不同。

我做错了什么？

这是完整的 SOAP 请求：

标签： validation soap signature canonicalization

【解决方案1】：

我删除了标签和匹配摘要之间的所有换行符和空格。要使用的正确 XML 是：

<u:Timestamp u:Id="uuid-cd1febd3-a76a-4148-8a3e-367aee62293d-1" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"><u:Created>2009-11-11T17:37:49.000Z</u:Created><u:Expires>2009-11-11T17:42:49.000Z</u:Expires></u:Timestamp>
