WSO2身份服务器OAuth2承载SAML断言-Java 学习之路

我在使用WSO2 Identity Server时遇到了问题 .

我在Identity Server中使用SAML2进行SSO的Web服务器 . 登录后，Identity Server将返回saml响应消息：

我从SAML2响应中提取Assertion标记并使用base64对其进行编码，并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：

我只在Identity Server中设置SAML2服务提供程序，并使用默认的Resident Identity Provider作为Identity Server中的身份提供程序 .

我在OAuth2 SAML断言流程中做错了什么，或者我错过了服务器中的某些配置？
非常感谢你 .

您需要从SAML2响应中提取Assertion标记并将其转换为 base64 URL encode . 请按照以下步骤操作 .
- 您需要删除换行符 .
- URL编码
- 编码base 64客户端ID和客户端密钥
（注意：您可以直接将其转换为base64 URL编码，无需使用两个步骤执行此操作）

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
```
当断言签名私钥的公钥与验证公钥不匹配时，会发生此错误 . 因此，在这种情况下，API Manger端用于验证SAML断言中的发送的公钥与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的证书添加到wso2carbon.jks（并记住别名） .

有关详细信息，请参阅以下参考 .
