WSO2 身份服务器 OAuth2 承载 SAML 断言
WSO2 Identity Server OAuth2 Bearer SAML Assertion
我在使用 WSO2 身份服务器时遇到问题。
我有一个 Web 服务器在用于 SSO 的身份服务器中使用 SAML2。
登录后，Identity Server return saml 响应信息：

我从 SAML2 响应中提取断言标记并使用 base64 对其进行编码，然后将请求发送到身份服务器以使用 OAuth2 SAML Aseertion 请求 OAuth2 Bearer 令牌。
但是我在服务器中收到以下异常消息：

我在Identity Server中只设置了SAML2服务提供者，在Identity Server中使用默认的Resident Identity Provider作为身份提供者
我是否在 OAuth2 SAML 断言流程中做错了什么，或者我是否缺少服务器中的某些配置？
非常感谢。
您需要从 SAML2 响应中提取断言标记并将其转换为 base64 URL 编码。请按照以下步骤操作。
- 您需要删除换行符。
- URL 编码
- 对客户端 ID 和客户端密码进行 base 64 编码
(注意：可以直接转成base64URL编码，不需要两步)
然后使用下面的 curl 命令
curl -k -d "grant_type=urn:ietf:params:oauth:grant-type:saml2-bearer&assertion=<Assertion_provided_by_client>&scope=PRODUCTION" -H "Authorization: Basic <Base64 encoded consumer key:consumer secret>, Content-Type: application/x-www-form-urlencoded" https://<IP of the APIM server>:9443/oauth2/token
当断言签名私钥的 public 密钥与验证 public 密钥不匹配时，会发生此错误。因此，在这种情况下，API Manger 端用于验证 SAML 断言发送的 public 密钥与 Identity Server 用于签署 SAML 断言的私钥不匹配。
另一种选择是将他们提供给您的证书添加到 wso2carbon.jks（并记住别名）。
请参阅以下参考资料了解更多信息。

我在Identity Server中只设置了SAML2服务提供者，在Identity Server中使用默认的Resident Identity Provider作为身份提供者
我是否在 OAuth2 SAML 断言流程中做错了什么，或者我是否缺少服务器中的某些配置？
非常感谢。
您需要从 SAML2 响应中提取断言标记并将其转换为 base64 URL 编码。请按照以下步骤操作。
- 您需要删除换行符。
- URL 编码
- 对客户端 ID 和客户端密码进行 base 64 编码
(注意：可以直接转成base64URL编码，不需要两步)
然后使用下面的 curl 命令
curl -k -d "grant_type=urn:ietf:params:oauth:grant-type:saml2-bearer&assertion=<Assertion_provided_by_client>&scope=PRODUCTION" -H "Authorization: Basic <Base64 encoded consumer key:consumer secret>, Content-Type: application/x-www-form-urlencoded" https://<IP of the APIM server>:9443/oauth2/token
当断言签名私钥的 public 密钥与验证 public 密钥不匹配时，会发生此错误。因此，在这种情况下，API Manger 端用于验证 SAML 断言发送的 public 密钥与 Identity Server 用于签署 SAML 断言的私钥不匹配。
另一种选择是将他们提供给您的证书添加到 wso2carbon.jks（并记住别名）。
请参阅以下参考资料了解更多信息。
