在ios中使用aws ios iot sdk爲我們自己的mqtt服務器

Question

我們使用AWS iOS IoT SDK和ssl配置。我們按照https://github.com/awslabs/aws-sdk-ios-samples/tree/master/IoT-Sample/Swift作爲參考。 這裏，我們的服務器的終點將是格式

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

我們進口PKCS12文件中捆綁並能夠連接，發佈，訂閱服務器。

後來我們想到在我們的組織內部有本地網絡解決方案，我們爲服務器MQTT代理設置rabbitmqhttps：//www.rabbitmq.com/ssl.html#keys-and-certs。目前，我們正在嘗試使用ec2實例，後者將設置本地服務器。和終點是

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

現在我無法連接使用AWS IOT IOS SDK來的RabbitMQ服務器。

但是，如果我使用https://github.com/emqtt/CocoaMQTT示例，我可以連接到aws iot服務器端點，rabbitmq服務器端點。

現在我應該做些什麼來使用aws ios ios sdk https://github.com/aws/aws-sdk-ios/tree/master/AWSIoT連接到rabbitmq服務器端點。我應該在sdk中做什麼編輯？

下面是使用aws iot ios sdk嘗試連接到rabbitmq服務器時的日誌。

Answer 1

你的目標是？您是否希望本地MQTT代理進行測試，還是希望運行自己的MQTT代理並使用AWS iOS IoT SDK連接到它？

如果你想經營自己的經紀人，我建議你仔細考慮一下，因爲它在規模上變得困難。我沒有嘗試對本地代理使用AWS IoT SDK，但您的日誌顯示SSL握手失敗。我猜測這是因爲您的應用程序和RabbitMQ之間的相互身份驗證失敗，原因是服務器證書不匹配。

AWS物聯網使用相互認證不只是客戶端身份驗證來建立信任：http://docs.aws.amazon.com/iot/latest/developerguide/managing-device-certs.html

你需要做兩件事情1）在iOS的SDK，其中AWS物聯網服務器CA設置（https://www.symantec.com/content/en/us/enterprise/verisign/roots/VeriSign-Class%203-Public-Primary-Certification-Authority-G5.pem確定）並更換爲您的RabbitMQ代理提供CA，2）配置RabbitMQ進行相互認證（如果支持）。

祝你好運。
