我是 kura 的新手，我一直在尝试使用 Amit 的 MQTT应用程序远程卸载部署包，但我无法这样做。这是我从应用程序发送的请求有效负载 -

dp.name=hello_osgi

job.id=12345891011L

dp.version=1.0.0

我在响应主题中收到以下错误-

    response.exception.message=java.lang.String cannot be cast to java.lang.Long,
    response.exception.stack=java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Long

         Malformed uninstall request

以下是kura控制台-

还有其他方法可以发送请求有效载荷吗？

快速浏览一下DeploymentPackageUninstallOptions会发现您是job.id作为String而不是Long发送的。

代替

String reqId = "12345891011L";
payload.addMetric("job.id", reqId);

代码应该做

long reqId = 12345891011L;
payload.addMetric("job.id", reqId);

或者更好的是，使用已经以正确类型实现所有方法的KuraUninstallPayload 。

我不知道 Amit 的 MQTT UTility，但我认为您可以通过某种方式设置变量的类型（或更改他的应用程序以设置正确的类型，然后发送拉取请求）。
