我正在深入研究azure Iot集线器和连接技术的工作,使用此处的教程:https://azure.microsoft.com/nl-nl/documentation/articles/iot-hub-csharp-csharp-getstarted/
运行接收器示例时(本文的这一部分:https://azure.microsoft.com/nl-nl/documentation/articles/iot-hub-csharp-csharp-getstarted/#receive-device-to-cloud-messages)
我收到错误:
var d2cPartitions = eventHubClient.GetRuntimeInformation().PartitionIds;
我收到此错误(底部的完整错误日志):
Message=An AMQP error occurred (condition='amqp:link:redirect').
我无法找到导致这种情况的原因,因为我使用了一个基本示例,并且我的集线器显示正确配置 . 发送工作很好btw . 有人有个主意吗?
完整的错误日志:
Microsoft.ServiceBus.Messaging.MessagingException was unhandled
HResult=-2146233088
IsTransient=true
Message=An AMQP error occurred (condition='amqp:link:redirect').
Source=Microsoft.ServiceBus

您的问题来自您的企业代理 . 您可以通过将Service Bus环境通信模式设置为HTTP,轻松地为EventHubClient定义代理 . 在你的c#中添加:
然后在你的app.config文件中添加:
希望能帮助到你
好的,这很奇怪 . 这解决了自己 . 发布后我离开回家,测试发送和接收程序工作正常 . (是的,为了安全,我确实重启了它们)
原因?不知道 . 也许集线器的每日清理解决了它,但它仍然很奇怪 .
如果有人遇到这个问题并且有明确的原因和解决方案,那么请把它作为答案 . 如果这可能再次发生,则可能需要它 .
可能的原因是关闭端口或代理服务器不让程序请求通过 . 我在家里尝试了它,没有代理,它工作得很好 . 因此,如果您遇到此问题,请在其他位置尝试 .
