MQTT.fx 无法连接到 AWS IoT (MqttException)
MQTT.fx can't connect to AWS IoT (MqttException)
我正在尝试学习本教程https://circuitdigest.com/tutorial/getting-started-with-amazon-aws-for-iot-projects
我一次又一次地执行了所有步骤，但是在 MQTT.fx 中单击“连接”按钮时我无法摆脱 MqttException 错误。
我从 AWS IoT 下载证书并将它们保存在 C:\temp 文件夹中。我还检查了 MQTT.fx 中的日志选项卡，您可以在下面看到。您知道如何解决吗？
非常感谢！

我解决了我的问题。
这是关于下载错误的证书。您可以在这里找到详细的解决方案。
在 AWS IoT 中创建事物后，下载所有 3 个证书。
如果你想获得 MQTT.fx 所需的 CA 证书，你需要去 here（你会在 AWS IoT 的下载证书部分看到这个 link你创建你的东西）并单击 RSA 2048 位密钥：Amazon Root CA 1 link。将打开新标签页。
将此证书复制并粘贴到您的记事本中。保存时将其命名为 Amazon_Root_CA_1.pem 和 select 所有文件类型。
将所有证书放在一个文件中。我把它们放在 C:\temp 文件夹下。
最后，我的配置是这样的：MQTT.fx configuration
现在 MQTT.fx 有望工作:)
