Java 无法获取提供程序服务实例的目标

在xsuaa登录后，我正在点击获取com.sap.cloud.sdk.cloudplatform.security.user.user&com.sap.cloud.sdk.cloudplatform.connectivity.Destination对象

在本地登录xsuaa后获取目标时发生以下异常

请从中查找我的非工作代码

请建议我如何解决这个问题

com.sap.cloud.sdk.cloudplatform.connectivity.exception.DestinationAccessException: com.sap.cloud.sdk.cloudplatform.connectivity.exception.DestinationAccessException: Failed to get destinations of provider service instance: Failed to get access token for destination service. If your application is running on Cloud Foundry, make sure to have a binding to both the destination service and the authorization and trust management (xsuaa) service, AND that you either properly secured your application or have set the "ALLOW_MOCKED_AUTH_HEADER" environment variable to true. If your application is not running on Cloud Foundry, for example, when deploying to a local container, consider declaring the "destinations" environment variable to configure destinations.

从本质上讲，执行该运行的前提条件在错误消息中命名

无法获取提供程序服务实例的目标：无法获取 目标服务的访问令牌。如果您的应用程序正在运行 在Cloud Foundry上，确保对目标和目标都有绑定 服务以及授权和信任管理xsuaa服务， 并且您或者正确保护了应用程序，或者已经设置了 允许\u MOCKED\u AUTH\u头环境变量为true。如果你的 应用程序未在Cloud Foundry上运行，例如，当 部署到本地容器，考虑声明目的地 用于配置目标的环境变量

因此，请确保两个环境变量都按预期设置。

---

在我们的博客文章中找到有关destinationsvariable的更多信息。

如Emdee所述，您可以使用ALLOW\u MOCKED\u AUTH\u HEADER变量模拟目标。但是，使用此变量还将使对基于JWT的用户的本地访问变得无用：

---

或者，您必须通过VCAP_服务向目标服务提供配置，类似于这里回答的XSUAA配置：基于CloudFoundry中的实际服务绑定。请使用cf env将这些值从cf中的绑定应用程序复制到本地设置。免责声明：我自己没有尝试过，但它应该是这样工作的。

Philipp，我在上面的问题描述中附上了图片，您的答案是在“连接”选项卡下获取目的地吗？Dama，请澄清您是在本地机器上还是在SAP云平台上运行示例。这种区别会影响您指定目的地的位置和方式。您好，Dama，您发布的配置与目的地本身的配置有关，而不是目的地服务与应用程序的技术绑定。如我在回答中所述，请在实际绑定到scp文档实例的应用程序上使用cf env APP_名称。这应该是这样的：系统提供的：{VCAP_服务：{destination:[{binding_name:null，credentials:{…Philipp，我添加了环境变量名作为目的地，值作为[{destination:[{credentials:{xsappname:，clientid:，clientsecret:，identityzone:，url:，verificationkey:}，标记：[目的地，文档]}]}]在本地。但是获取com.sap.cloud.sdk.cloudplatform.connectivity.exception.DestinationAccessException:没有为属性名定义有效的JSON原语。异常。请告诉我确切的JSON值。否，不是作为专用目标变量，而是作为VCAP_服务的一部分以及xsuaa定义的同级。请删除destin仅用于简单启动项目且覆盖目标服务的潜在用途的VCAP_变量。查看在执行cf env APP_名称时VCAP_服务变量是如何构造的。只需按原样提供给本地应用程序，包括正确的公钥、URL等。这是必要的，以便在OAuth Fl下可以启动带有目标服务的ow。
