OpenSaml encryptedID 验证失败

Question

我的需求是将nameId加密后在AuthnRequest中发送。我遇到了 openSaml (v 2.6.1) Validator SubjectShemaValidator 的问题。请求验证失败并出现错误 "ID or SubjectConfirmation required"，因为没有 BaseID、BaseID 或 SubjectConfirmations。

这是我的身份验证请求：

<saml2p:AuthnRequest AssertionConsumerServiceURL="https:..."

这是 OpenSAML 验证器上的错误，因为它不检查 EncryptedID 吗？或者我错过了什么？？

Answer 1

你可以直接这样输入而不是 nameId 的加密

AuthnRequest request = buildSAMLObject(AuthnRequest.class);


        NameIDPolicy nameIdPolicy = buildSAMLObject(NameIDPolicy.class);
        nameIdPolicy.setAllowCreate(true);
        nameIdPolicy.setFormat(NameIDType.EMAIL);
        request.setNameIDPolicy(nameIdPolicy);


public static <T> T buildSAMLObject(final Class<T> clazz) {
        T object = null;
        try {
            XMLObjectBuilderFactory builderFactory = Configuration
                    .getBuilderFactory();
            QName defaultElementName = (QName) clazz.getDeclaredField(
                    "DEFAULT_ELEMENT_NAME").get(null);
            object = (T) builderFactory.getBuilder(defaultElementName)
                    .buildObject(defaultElementName);
        } catch (IllegalAccessException e) {
            throw new IllegalArgumentException("Could not create SAML object");
        } catch (NoSuchFieldException e) {
            throw new IllegalArgumentException("Could not create SAML object");
        }

        return object;
    }

为了解决这个问题，我必须注销默认主题验证器并注册自定义验证器（包括 EncryptedID）。

validatorSuite = Configuration.getValidatorSuite(SAML_VALIDATOR_SUITE_ID);
    // deregister default subject validator and register customized validator (including EncryptedID).
    List<Validator> validators = validatorSuite.getValidators(Subject.DEFAULT_ELEMENT_NAME);
    if (validators != null && validators.size() > 0) {
        validatorSuite.deregisterValidator(Subject.DEFAULT_ELEMENT_NAME, validators.get(0));
    }
    validatorSuite.registerValidator(Subject.DEFAULT_ELEMENT_NAME, new SubjectSchemaValidator());

希望对您有所帮助。
