获取“Microsoft.Azure.ServiceBus.ServiceBusCommunicationException”在写一个简单的测试时 [英] Getting a "Microsoft.Azure.ServiceBus.ServiceBusCommunicationException" when writing a simple test

问题描述

您好，

我正在尝试重现此处解释的有关服务总线使用的简单示例：  https://docs.microsoft.com/en- us / azure / service-bus-messaging / service-bus-dotnet-get-started-with-queues

但是，我收到以下异常

抛出异常：System.Private.CoreLib.dll中的'Microsoft.Azure.ServiceBus.ServiceBusCommunicationException'

，消息为：

异常：连接尝试失败，因为连接方在一段时间后没有正确响应，或者建立的连接失败，因为连接的主机未能响应ErrorCode：TimedOut

 堆栈跟踪：   在Microsoft的.Azure.ServiceBus.Core.MessageSender.OnSendAsync（IList`1 messageList）中的C：\\\ source \ azure-service-bus-dotnet \src\Microsoft.Azure.ServiceBus\Core\MessageSender。 cs：第562行

   在Microsoft.Azure.ServiceBus.RetryPolicy.RunOperation（Func`1操作，TimeSpan operationTimeout）中的C：\\\ source \ azure-service-bus-dotnet \src \ Microsoft.Azure.ServiceBus \RetryPolicy。 cs：第85行

   在Microsoft.Azure.ServiceBus.RetryPolicy.RunOperation（Func`1操作，TimeSpan operationTimeout）中的C：\\\ source \ azure-service-bus-dotnet \src \ Microsoft.Azure.ServiceBus \RetryPolicy。 cs：第107行

   位于C：\ source \ azure-service-bus-dotnet \ src \ Mysrosoft.Azure.ServiceBus \ Core \中的Microsoft.Azure.ServiceBus.Core.MessageSender.SendAsync（IList`1 messageList） MessageSender.cs：第252行

    at ServiceBusHelloWorld.Program.SendMessagesAsync（Int32 numberOfMessagesToSend）in C：\ _dev\ServiceBusHelloWorld\ServiceBusHelloWorld\ServiceBusHelloWorld\Program.cs:line 58

此行中的

（SendMessagesAsync（）方法）：

 //将消息发送到队列
 await queueClient.SendAsync（消息）; 

这可能是非开放端口问题吗？如果是这样，应该使用哪个端口来处理ServiceBus的响应？

解决方案

我已经完成了文档中提到的确切步骤在帖子中分享，我能够毫无问题地成功运行此功能。这可能是网络防火墙的问题。尝试从不同的网络运行

Hello,

I am trying to reproduce the simple example explained here about the use of Service Bus: https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-dotnet-get-started-with-queues

However, I am getting the following exception

Exception thrown: 'Microsoft.Azure.ServiceBus.ServiceBusCommunicationException' in System.Private.CoreLib.dll

with the message:

Exception: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond ErrorCode: TimedOut
 Stack Trace:    at Microsoft.Azure.ServiceBus.Core.MessageSender.OnSendAsync(IList`1 messageList) in C:\source\azure-service-bus-dotnet\src\Microsoft.Azure.ServiceBus\Core\MessageSender.cs:line 562
   at Microsoft.Azure.ServiceBus.RetryPolicy.RunOperation(Func`1 operation, TimeSpan operationTimeout) in C:\source\azure-service-bus-dotnet\src\Microsoft.Azure.ServiceBus\RetryPolicy.cs:line 85

   at ServiceBusHelloWorld.Program.SendMessagesAsync(Int32 numberOfMessagesToSend) in C:\_dev\ServiceBusHelloWorld\ServiceBusHelloWorld\ServiceBusHelloWorld\Program.cs:line 58

in this line (SendMessagesAsync() method):

// Send the message to the queue
await queueClient.SendAsync(message);

Could it be an non-open ports issue? If so, what port should be used to handle the ServiceBus' response?

解决方案

I have gone through the exact steps mentioned in the documentation shared in the post and I am able to successfully run this without any issues. It might be an issue with the network firewall. Try running from different network
