在ios中使用aws ios iot sdk为我们自己的mqtt服务器

Question

我们使用AWS iOS IoT SDK和ssl配置。我们按照https://github.com/awslabs/aws-sdk-ios-samples/tree/master/IoT-Sample/Swift作为参考。 这里，我们的服务器的终点将是格式

https://xxxxxxxxxx.iot ..amazonaws.com

我们进口PKCS12文件中捆绑并能够连接，发布，订阅服务器。

后来我们想到在我们的组织内部有本地网络解决方案，我们为服务器MQTT代理设置rabbitmqhttps：//www.rabbitmq.com/ssl.html#keys-and-certs。目前，我们正在尝试使用ec2实例，后者将设置本地服务器。和终点是

SSL：//ec2-..compute.amazonaws.com：8883

现在我无法连接使用AWS IOT IOS SDK来的RabbitMQ服务器。

但是，如果我使用https://github.com/emqtt/CocoaMQTT示例，我可以连接到aws iot服务器端点，rabbitmq服务器端点。

现在我应该做些什么来使用aws ios ios sdk https://github.com/aws/aws-sdk-ios/tree/master/AWSIoT连接到rabbitmq服务器端点。我应该在sdk中做什么编辑？

下面是使用aws iot ios sdk尝试连接到rabbitmq服务器时的日志。

Answer 1

你的目标是？您是否希望本地MQTT代理进行测试，还是希望运行自己的MQTT代理并使用AWS iOS IoT SDK连接到它？

如果你想经营自己的经纪人，我建议你仔细考虑一下，因为它在规模上变得困难。我没有尝试对本地代理使用AWS IoT SDK，但您的日志显示SSL握手失败。我猜测这是因为您的应用程序和RabbitMQ之间的相互身份验证失败，原因是服务器证书不匹配。

AWS物联网使用相互认证不只是客户端身份验证来建立信任：http://docs.aws.amazon.com/iot/latest/developerguide/managing-device-certs.html

你需要做两件事情1）在iOS的SDK，其中AWS物联网服务器CA设置（https://www.symantec.com/content/en/us/enterprise/verisign/roots/VeriSign-Class%203-Public-Primary-Certification-Authority-G5.pem确定）并更换为您的RabbitMQ代理提供CA，2）配置RabbitMQ进行相互认证（如果支持）。

祝你好运。
