用Spring-SAML处理SAML响应

我使用Spring SAML开发了一个服务提供商。 我已经配置了几个IDP，每个IDP都有不同的属性命名约定

在成功的AuthN过程之后，我是否可以（在Tomcat的

logs/catalina.out

文件上）记录整个SAML响应

是否有一些本机特性来定义特定IdP的

EntityID

与映射返回的

用户ID

的属性之间的关联

我也在阅读有关OID格式的文章：如何正确解码此类数据

---

更新：

关于第一个问题，根据文档，我设置了调试日志和身份验证日志，如下所示：

// Logger for SAML messages and events
@Bean
public SAMLDefaultLogger samlDefaultLogger() {
    SAMLDefaultLogger samlDefaultLogger = new SAMLDefaultLogger();
    samlDefaultLogger.setLogMessages(true);
    samlDefaultLogger.setLogErrors(true);
    return samlDefaultLogger;
}

log4j.logger.org.opensaml=DEBUG

如下：

@Bean
public SAMLDefaultLogger samlDefaultLogger() {
    SAMLDefaultLogger samlDefaultLogger = new SAMLDefaultLogger();
    samlDefaultLogger.setLogMessages(true);

    return samlDefaultLogger;
}

通过正确配置Maven

pom.xml

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

请注意，最后两行是由我手动定义的

您可以使用调试日志（）或身份验证日志（），并将

logMessages

属性设置为

true

。两者都能够将消息记录到catalina.out（因为它们只是将日志发送到slf4j）

不需要，您需要将这种逻辑实现到

SAMLUserDetailsService

您可以通过调用

getAttributeByName

和

getAttributes

，从

SAMLCredential

对象加载所有接收到的属性，返回的

Attribute

对象包含允许您解析任何接收到的属性结构的方法。Spring SAML中没有包含特定的解析器

具有某些OID类型数据的属性通常编码为

xsd:string

或

xsd:xsd:base64Binary

，您可以获得这两个属性的原始字符串值，如第9.4章的示例所示。提供将编码字符串解析为相应Java类型（基于OID）的其他可能性超出了Spring SAML的范围

你对它感兴趣吗？你指的是这个吗？

添加这个怎么样：

log4j.logger.PROTOCOL_MESSAGE=DEBUG

或者这是回写：

<logger name="PROTOCOL_MESSAGE" level="DEBUG" />

我应该解析此类响应：该文档中的值只是字符串，您不需要对它们进行任何特殊解析。请务必阅读手册中的第6.5章。。。它包含以下内容：log4j.logger.PROTOCOL_MESSAGE=DEBUG，它将开始记录SAML消息的内容。抱歉，我完全错过了这一行！没问题。顺便说一句，由于某些原因，我在日志中没有看到SAMLDefaultLogger的输出，否则会包含解密的消息。您可能仍然希望了解这一点，这可能是一些日志配置问题。该行应该如下所示：2014-07-29 15:46:54.676 INFO 7688---[nio-8080-exec-5]o.s.security.saml.log.SAMLDefaultLogger:AuthNRequest；成功；0:0:0:0:0:0:0:1;urn:it:miur:prisma；www.ssoccircle.com ;；；
