Azure函数预编译timerTrigger错误

Question

我部署了一个使用timerTrigger预编译的Azure Function。当我激活所有日志时出现以下异常

2017-04-13T12:53:03.836 {"id":"b91045c2-ff21-4c9d-bd14-88e90723adbe","requestId":"37212a13-73ae-4e1e-9f1e-130f3865e258","statusCode":500,"errorCode":0,"messsage":"Sequence contains no matching element"} 2017-04-13T12:53:03.836 System.InvalidOperationException: Sequence contains no matching element at System.Linq.Enumerable.First[TSource](IEnumerable1
source, Func2 predicate) at Microsoft.Azure.WebJobs.Script.WebHost.Controllers.AdminController.Invoke(String name, FunctionInvocation invocation) at lambda_method(Closure , Object , Object[] ) at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass10.b__9(Object instance, Object[] methodParameters) at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.Execute(Object instance, Object[] arguments) at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ExecuteAsync(HttpControllerContext controllerContext, IDictionary`2 arguments, CancellationToken cancellationToken) --- End of stack trace from previous location where exception was thrown ---

我的函数.json

{
  "scriptFile": "..\\bin\\Plop.Statistics.dll",
  "entryPoint": "Plop.Statistics.S4BStatisticsCommand.Function.Run",
  "bindings": [
    {
      "name": "myTimer",
      "type": "timerTrigger",
      "direction": "in",
      "schedule": "0 */1 * * * *"
    },
    {
      "name": "outputQueueItem",
      "queueName": "command-queue",
      "type": "queue",
      "direction": "out",
      "connection": "AzureWebJobsStorage"
    }
  ],
  "disabled": false
}

和我的功能

namespace Plop.Statistics.S4BStatisticsCommand{
public class Function
{
    public static async Task Run(TimerInfo myTimer, ICollector<S4BStatisticCommand> outputQueueItem, TraceWriter log)
    {
       log.Info("hello");
    }

感谢您的帮助!

编辑:

timerTrigger没有被触发，因为没有找到该函数。这里是日志:

If you're using binding extensions (e.g. ServiceBus, Timers, etc.) make sure you've called the registration method for the extension(s) in your startup code (e.g. config.UseServiceBus(), config.UseTimers(), etc.).

Answer 1

定时器触发器需要 Microsoft.Azure.WebJobs.Extensions nuget，作业主机应该注册您的函数。

查看此precompiled function article ，特别是“转换为类文件”部分。

3. If you’re using timer triggers, add the NuGet package Microsoft.Azure.WebJobs.Extensions.
