MobileFirst V8.0 消费者版无法调用适配器过程

Question

我使用的是 MobileFirst V8.0 消费者版。我已经为我的应用程序设置了一个测试服务器。当我从移动应用程序调用适配器过程（受安全检查保护）时，服务器出现以下错误：

此外，我在我的 MFP 服务器实例中使用用户定义的密钥库。

Answer 1

我按照 this 文档中所述，使用带有 -keyalg RSA 选项的以下命令重新生成了密钥库，并重新配置了密钥库，此错误消失了：

keytool -keystore <keystore name> -genkey -alias <alias name> -keylag RSA

之前我参考了 MFP 控制台中名为在 MobileFirst 控制台中从以下位置创建您自己的密钥库的指南 Runtime Settings --> Keystore 并且缺少 -keyalg RSA 选项。
