java - 将现有 SAML 断言添加到 WS 安全 header

我使用 spring-ws (2.1.4) WebServiceTemplate 和自定义 WebServiceMessageCallback 来插入带有 SAML 的安全 header ，我将作为 org.w3c.dom.Element 接收该 header ，并且仅创建自己用于测试。

我使用 webServiceTemplate.marshalSendAndReceive(request, new HeaderCallback(ctx, uri)) 来编码并发送我的请求。

我的问题是服务器端签名验证失败，摘要不匹配。比较发送之前和接收之后的 SAML 输出，我发现在接收端，我在发送之前没有的元素上有命名空间声明。

我当前在回调中执行的操作:

@Override
public void doWithMessage(WebServiceMessage message) throws IOException, TransformerException {
    super.doWithMessage(message);

    Assert.isInstanceOf(SoapMessage.class, message);
    SoapMessage soapMessage = (SoapMessage) message;
    SoapHeaderElement securityHeader = soapMessage.getSoapHeader().addHeaderElement(WS_SECURITY_NAME);

    try {
        Transformer t = TransformerFactory.newInstance().newTransformer();
        t.transform(new DOMSource(assertion), securityHeader.getResult());
    } catch (org.springframework.oxm.MarshallingException ex) {
        throw new IOException(ex);
    }

有谁知道如何将元素插入 SOAP XML 中以确保该元素不会被修改？或者是否有其他方法可以使用 Spring WebServiceTemplate 来实现此目的？

我遇到了 org.apache.ws.security.saml.ext.SAMLCallback，它有一个 setAssertionElement 方法，但是我没有找到如何让它与 WebServiceTemplate(分别为 Wss4jSecurityInterceptor)一起使用，特别是考虑到我需要将现有的 SAML 断言作为参数传递。

编辑:我找到了一种不添加额外命名空间的方法。我现在正在做的是使用 javax.xml.soap.SOAPMessage 并导入节点:

@Override
public void doWithMessage(WebServiceMessage message) throws IOException, TransformerException {
    super.doWithMessage(message);

    Assert.isInstanceOf(SaajSoapMessage.class, message);

    try {
        SOAPMessage soapMessage = ((SaajSoapMessage) message).getSaajMessage();
        SOAPPart soapPart = soapMessage.getSOAPPart();
        SOAPEnvelope soapEnvelope = soapPart.getEnvelope();

        if (soapEnvelope.getHeader() == null) {
            soapEnvelope.addHeader();
        }

        SOAPHeaderElement securityElement = soapEnvelope.getHeader().addHeaderElement(WS_SECURITY_NAME);
        securityElement.appendChild(soapPart.importNode(assertion, true));

    } catch (SOAPException ex) {
        throw new IOException(ex);
    }

}

但是，即使差异显示输出之间没有差异验证仍然失败。此时，我不确定我是否可以信任输出，并且这样做确实不会改变 SAML...

还有什么想法可能导致摘要不匹配吗？

最佳答案

以下方法(我已经将其作为编辑记录在我的问题中)阻止添加其他 namespace 。

@Override
public void doWithMessage(WebServiceMessage message) throws IOException, TransformerException {
    super.doWithMessage(message);

    Assert.isInstanceOf(SaajSoapMessage.class, message);

    try {
        SOAPMessage soapMessage = ((SaajSoapMessage) message).getSaajMessage();
        SOAPPart soapPart = soapMessage.getSOAPPart();
        SOAPEnvelope soapEnvelope = soapPart.getEnvelope();

        if (soapEnvelope.getHeader() == null) {
            soapEnvelope.addHeader();
        }

        SOAPHeaderElement securityElement = soapEnvelope.getHeader().addHeaderElement(WS_SECURITY_NAME);
        securityElement.appendChild(soapPart.importNode(assertion, true));

    } catch (SOAPException ex) {
        throw new IOException(ex);
    }

}

我还让 SAML 验证正常工作。它与将 SAML 添加到 SOAP 消息的方式无关(也是我使用 Transformer 的原始方法 - 尽管它添加了额外的命名空间 - 现在已验证)。断言中缺少 ID。

这是我的 SAML 现在的样子:
