请求密钥时出现IOException:无效的设备密钥响应

问题描述：

我正在使用带有Google IOT的Pi 3来操作一些继电器，这些继电器控制灌溉系统上的阀门.该系统使用互联网获取天气预报以计算要消耗的水量，并使用NanoHTTPD提供UI.

I'm using a Pi 3 with google IOT to operate some relays that control valves on an irrigation system. The system uses the internet to get a weather forecast to work how much water to use, and uses NanoHTTPD to provide a UI.

它运行得很好，但偶尔我会遇到一个错误，该错误使整个过程停止.从日志文件中:

It's running nicely, but occasionally I get an error which stops the whole thing. From the log files:

对于如何阻止这种情况的发生，我深表感谢.

I'd appreciate some hint on how to stop this from happening.

谢谢.

答

简单.这意味着与IOT服务关联的Google控制台上的密钥与Mac/Pi 3上本地存储的密钥不匹配.

Simple. This means that the key on the Google Console that is associated with the IOT service is not matching the one stored locally on your Mac/Pi 3.

只需运行: keytool -list -v -keystore <your keystore> -storepass <your store password> 并将SHA1或SHA256下的密钥复制到Google控制台.

Just run: keytool -list -v -keystore <your keystore> -storepass <your store password> and copy the key under SHA1 or SHA256 to the Google Console.

如果keytool -genkeypair不存在，则可以创建keystore.

You can create a keystore if none is present by keytool -genkeypair.

对于其他有用的命令，请运行keytool -h.

For other useful commands run keytool -h.
