azure - 为 eventthub 触发器获取 Azure.WebJobs.Host.Listeners.FunctionListenerException

问题描述

我正在使用 azure webjobs v3 来触发 eventthub。直到某个时候一切正常。突然我变得低于错误。有人可以帮我解决这个问题吗？

public async Task Trigger00([EventHubTrigger("%eventhub-00%", Connection = "ConnectionString")] string message)
       {
          blah... 
       }

Host.Startup[0]
      The listener for function 'Trigger00' was unable to start.
Microsoft.Azure.WebJobs.Host.Listeners.FunctionListenerException: The listener for function 'Trigger00' was unable to start. ---> System.MissingMethodException: Method not found: 'Void Microsoft.Azure.EventHubs.EventHubsException..ctor(Boolean, System.String, System.Exception)'.

解决方案

我通过删除对 Microsoft.Azure.EventHubs 4.1.0 的直接依赖解决了这个问题。

Microsoft.Azure.WebJobs.Extensions.EventHubs3.0.6 依赖于Microsoft.Azure.EventHubs（2.1.0）的旧版本。我已阅读此包中有重大更改，这可能解释了该错误。

前：

    <PackageReference Include="Microsoft.ApplicationInsights" Version="2.10.0" />
    <PackageReference Include="Microsoft.Azure.Cosmos" Version="3.1.1" />
    <PackageReference Include="Microsoft.Azure.EventHubs" Version="4.1.0" />
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.EventHubs" Version="3.0.6" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="1.0.29" />

后：

    <PackageReference Include="Microsoft.ApplicationInsights" Version="2.10.0" />
    <PackageReference Include="Microsoft.Azure.Cosmos" Version="3.1.1" />
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.EventHubs" Version="3.0.6" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="1.0.29" />
