我正在使用版本为 5.2.0.RELEASE 的 spring-security 和 spring-security-saml2-service-provider。我正在尝试通过 IDP 进行身份验证以获取当前断言,以便将其映射到我们本地系统中的用户。我使用此代码获取 Saml2Authentication 对象
@Component
@Log4j
public class EventListener implements ApplicationListener<InteractiveAuthenticationSuccessEvent> {
@Override
public void onApplicationEvent(InteractiveAuthenticationSuccessEvent interactiveAuthenticationSuccessEvent) {
Object principal = interactiveAuthenticationSuccessEvent.getAuthentication().getPrincipal();
Saml2Authentication authentication = (Saml2Authentication)interactiveAuthenticationSuccessEvent.getAuthentication()
但我无法获得用户。我可以获得 saml2 响应(authentication.getSaml2Response),但我不确定如何获取带有用户 ID 的断言。
真的,我想从Java 代码中的 SAML 响应 (XML) 中检索属性和 NameID 。不确定 spring-security 中是否有可以帮助我的东西。
更新 所以经过一些工作,我使用 OpenSAML 库获取属性并解析 SAMLv2 响应。我不知道这是否是正确的方法
@Override
public void onApplicationEvent(InteractiveAuthenticationSuccessEvent interactiveAuthenticationSuccessEvent) {
Saml2Authentication authentication = (Saml2Authentication) interactiveAuthenticationSuccessEvent.getAuthentication();
try {
Document messageDoc;
BasicParserPool basicParserPool = new BasicParserPool();
basicParserPool.initialize();
InputStream inputStream = new ByteArrayInputStream(authentication.getSaml2Response().getBytes());
messageDoc = basicParserPool.parse(inputStream);
Element messageElem = messageDoc.getDocumentElement();
Unmarshaller unmarshaller = XMLObjectProviderRegistrySupport.getUnmarshallerFactory().getUnmarshaller(messageElem);
XMLObject samlObject = unmarshaller.unmarshall(messageElem);
Response response = (Response) samlObject;
response.getAssertions().forEach(assertion -> {
assertion.getAttributeStatements().forEach(attributeStatement ->
{
attributeStatement.getAttributes().forEach(attribute -> {
log.error("Names:" + attribute.getName() + getAttributesList(attribute.getAttributeValues()));
});
});
});
} catch (Exception e) {
log.error(e);
}
}
private List<String> getAttributesList(Collection<XMLObject> collection) {
return collection.stream().map(this::getAttributeValue)
.collect(Collectors.toList());
}
private String getAttributeValue(XMLObject attributeValue) {
return attributeValue == null ?
null :
attributeValue instanceof XSString ?
getStringAttributeValue((XSString) attributeValue) :
attributeValue instanceof XSAnyImpl ?
getAnyAttributeValue((XSAnyImpl) attributeValue) :
attributeValue.toString();
}
private String getStringAttributeValue(XSString attributeValue) {
return attributeValue.getValue();
}
private String getAnyAttributeValue(XSAnyImpl attributeValue) {
return attributeValue.getTextContent();
}
