未找到工作职能.尝试公开您的工作类别和方法

问题描述

首先，我查看了其他带有相同错误消息的 SO 帖子，但似乎没有一个可以解决我的问题.我尝试了许多排列和选项.我的函数构建良好，但不会在 CLI 中运行，我收到以下神秘错误.MSFT 文档似乎也没有答案.

First off, I have looked at the other SO posts with the same error message and none seem to resolve my issue. I have tried many permutations and options. My function builds fine but will not run in the CLI, I get the following cryptic error. The MSFT documentation does not seem to have the answers either.

未找到工作职能.尝试公开您的工作类别和方法.如果您使用绑定扩展(例如 ServiceBus、Timers 等)，请确保您已在启动代码中调用了扩展的注册方法(例如 config.UseServiceBus()、config.UseTimers() 等.).

我正在尝试运行计时器作业，然后将一组消息写入事件中心.我错过了什么?我已经为此奋斗了好几个小时.

I am trying to run a timer job and then write a collection of messages to an event hub. What am I missing? I have been fighting this for hours.

功能:

    [FunctionName("CreateData")]
    public static async Task Run([TimerTrigger("0 */5 * * * *")]TimerInfo myTimer,
        [EventHub("murraytest", Connection = "evingest")] IAsyncCollector<string> myeventhub,
        TraceWriter log)
    {
        await myeventhub.AddAsync("data1");
        await myeventhub.AddAsync("data2");
        await myeventhub.AddAsync("data3");

        log.Info($"COMPLETED: {DateTime.Now}");
    }

local.settings.json:

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "Eventhub": "UseDevelopmentStorage=true",
    "AzureWebJobsDashboard": "",
    "evingest": "Endpoint=sb://example.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=LtcqBLT5VWjg0dGMdIvxCcEGs8902010Y6y14iGg="

  }
}

包

function.json - 缺少任何 eventthub 绑定！

function.json - is missing any eventhub bindings!

{
  "generatedBy": "Microsoft.NET.Sdk.Functions-1.0.0.0",
  "configurationSource": "attributes",
  "bindings": [
    {
      "type": "timerTrigger",
      "schedule": "0 */5 * * * *",
      "useMonitor": true,
      "runOnStartup": false,
      "name": "myTimer"
    }
  ],
  "disabled": false,
  "scriptFile": "..\bin\AzFuncs.dll",
  "entryPoint": "AzFuncs.Function1.Run"
}

推荐答案

我发现的另一个问题，尤其是当您从另一个项目或版本转换时.

Another gotcha I found especially if you are converting from another project or version.

在 VS csproj 文件中，确保存在 AzureFunctionsVersion

In the VS csproj file, make sure AzureFunctionsVersion is present

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
</PropertyGroup>
...etc

如果您正在修改缺少此功能的项目，该工具会自动添加此功能，但不会添加.希望这可以帮助您节省我花费的 3 个小时 :-).

the tooling adds this automatically but not added if you are modifying a project where this was missing. Hope this helps you save the 3 hours it cost me :-).
