我正在使用 SAP S/4HANA Cloud SDK 进行 Deep Dive 9:通过 REST API 进行租户和用户感知微服务通信，并且已经在转换器服务和汇率服务之间建立了通信。

Deep Dive 9

但是，当我尝试运行

https://approuter-converter-accountID.cfapps.us10.hana.ondemand.com/converter?sum=100&from=EUR&to=USD

，它返回内部服务器错误。

我检查了 Converter 应用程序中的日志:

2018-06-19T15:42:15.86+1000 [APP/PROC/WEB/0] OUT Destination: ScpCfDestination(destinationType=HTTP, name=app, description=null, propertiesByName={Type=HTTP, ProxyType=Internet, Authentication=AppToAppSSO, URL=https://approuter-exchangerate-<accountid2>.cfapps.eu10.hana.ondemand.com, Name=app})

我可以看到HttpResponse成功了。但 Rates Json(返回实体)似乎不起作用。

我已按照博客中的所有步骤进行操作，但不知道为什么它会返回这样的错误。您能建议一下可能是什么原因吗？

更新:我在场景中使用了一名 S 用户和一名 P 用户。

在我更改并使用 2 个 P 用户后，我可以在转换器日志中看到响应。使用S用户有什么问题？

但是，响应不会显示在浏览器中。相反，它显示错误:内部服务器错误并在日志中写入:

最佳答案

请确保所调用的应用程序(汇率)得到正确保护。为此，请直接通过应用程序路由器调用应用程序:汇率应用程序路由器 URL/汇率，并在输入凭据后检查是否获得正确的负载。

如果没有，请根据您的账户数据检查并修改您的xs-security-exchangerate.json和manifest-approuter-exchangerate.yml。如果发生更改，请重新运行汇率服务的部署和服务绑定(bind)。
