Soap规范化转换

Question

用于创建摘要值的转换

<ds:Reference URI="#TS-f3c103e9-1897-43d8-8cf6-274bdb647678">
    <ds:Transforms>
       <ds:Transform Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#">
          <ec:InclusiveNamespaces xmlns:ec="http://www.w3.org/2001/10/xml-exc-c14n#" PrefixList="wsse soap"/>
       </ds:Transform>
   </ds:Transforms>
   <ds:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1"/>
   <ds:DigestValue>1rjXQQWVMM5KBWY8uswUynk6PCk=</ds:DigestValue>
</ds:Reference>

引用的元素。

<wsu:Timestamp wsu:Id="TS-f3c103e9-1897-43d8-8cf6-274bdb647678">
  <wsu:Created>2016-02-24T15:32:12.693Z</wsu:Created>
  <wsu:Expires>2016-02-24T15:37:12.693Z</wsu:Expires>
</wsu:Timestamp>

在根节点上应用上述元素的命名空间

null

您需要弄清楚java库或API是如何创建它发送给SHA1方法的规范化XML的。

使用Apache Commons Codec（https://Commons.Apache.org/proper/commons-codec/）并从Timestamp元素和Transform元素中包含的名称空间中猜测C14n的XML，我能够获得相同的摘要值:1RJXQQWVMM5KBWY8USWUYNK6PCK=

下面是我使用的代码：

import org.apache.commons.codec.binary.Base64;
import org.apache.commons.codec.digest.DigestUtils;

public class Sha1Test {

    public static void main(String args[]) throws Exception {
        String data = "<wsu:Timestamp xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:wsse=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd\" xmlns:wsu=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\" wsu:Id=\"TS-f3c103e9-1897-43d8-8cf6-274bdb647678\"><wsu:Created>2016-02-24T15:32:12.693Z</wsu:Created><wsu:Expires>2016-02-24T15:37:12.693Z</wsu:Expires></wsu:Timestamp>";
        printShaDigest(data);
    }

    static void printShaDigest(String data) {
        System.out.println("data = " + data);
        System.out.println("sha1 = " + new String(Base64.encodeBase64(DigestUtils.sha1(data.getBytes()))));
    }

}
