我想使用SAP CloudSDK 3.20.0向内部部署的SAP ABAP系统发送一个自定义OData请求"自定义"意味着我不能使用虚拟数据模型，而是组装请求URL"；"手工"；并像处理常规REST请求一样自己处理响应。
我的应用程序使用Java和Spring Boot运行。预期的请求需要一段时间才能完成，因此是从异步线程发送的。
我已经设置了一个云连接器，可以证明代码和配置在几个都使用基本身份验证的目的地上运行良好。现在，第一次尝试使用Principal Propagation时，代码在尝试获取HTTP客户端时失败，并出现异常：
try {
Destination destination = DestinationAccessor.getDestination(destinationName);
HttpDestination httpDestination = destination.asHttp().decorate(DefaultErpHttpDestination::new);
// this fails:
HttpClient httpClient = HttpClientAccessor.getHttpClient(httpDestination);
// ...
} catch (Exception exception) {
// receives
// DestinationAccessException: "Failed to get on-premise proxy headers."
// PrincipalAccessException: "Could not read a principal from neither
// a given JWT nor a given Basic Authentication header."
// full stack trace below
}
我的假设是，我对正在运行的异步线程做了错误的处理，我没有完全传递上下文，也没有以正确的方式让CloudSDK传播主体。
我正在做的一件事是，我使用AuthTokenAccessor.getCurrentToken()在原始线程中检索安全令牌，使用AuthTokenAccessor.executeWithAuthToken(authToken, command::run)将令牌传播到从那里异步启动的线程。
不幸的是，使用CloudSDK的异步线程是一片空白，我找不到任何文档或教程来解释这里到底需要什么。

关于如何使用Cloud SDK异步运行操作的子问题：此处对此进行了说明。
AFAI可以看到你做得很正确。如果您不确定具体需要哪些信息，或者希望避免从授权令牌中多次提取信息，则可以考虑传递完整的线程上下文。
如果你发现文档缺少重要信息，或者对如何增强它有想法，我建议你在公共GitHub上提出问题或打开拉取请求。
更新：
Cloud SDK3.26.0支持此身份验证类型。
初始答案：
从示例性异常堆栈竞赛中，我注意到授予类型urn:ietf:params:oauth:grant-type:jwt-bearer无法与预期的令牌类型匹配。这意味着，SAP Cloud SDK并不真正支持。老实说，看到这种情况我很惊讶。
你能告诉我们，你正在研究哪个SCP景观吗？我们有办法重现您的设置吗？您从哪里获得访问令牌？您是否使用方法？
作为一种潜在的解决方法，在调查和修复完成之前，您可以尝试以下方法：
PrincipalFacade principalFacade = PrincipalAccessor.getPrincipalFacade();
((ScpCfPrincipalFacade) principalFacade).setIdExtractorFunction(
"urn:ietf:params:oauth:grant-type:jwt-bearer",
jwt -> jwt.getClaim("user_name").asString());
