Question

我正在将Azure耐用功能项目从.NET Core 2.1升级到2.2。我已将所有NuGet软件包更新为与.NET Core 2.2兼容的最新版本（据我所知）。耐用客户端功能（StartOrchestration）配置有按预期方式工作的计时器触发器（如下所示）。

不起作用的是，编排触发函数（SearchOrchestration）从未被调用，我也不知道为什么。我是否更新到无效的NuGet软件包？我只是没有看到明显的错误？

作为参考，我一直在查看Bindings for Durable Functions document，它看起来像我的代码应该可以正常工作……但是没有。

持久功能编排：

    public static class SearchIndexDurableFunctions
    {
        [FunctionName(nameof(StartOrchestration))]
        public static async Task StartOrchestration(
            [TimerTrigger("%CronExpression%")]TimerInfo myTimer,
            [DurableClient(TaskHub = "%TaskHub:Name%")]IDurableOrchestrationClient starter,
            ILogger logger)
        {
            var nextRunTime = myTimer.Schedule.GetNextOccurrence(DateTime.Now);
            logger.LogInformation($">> Next run time will be: {nextRunTime.ToLocalTime()}");

            var instanceId = Guid.NewGuid().ToString();

            var result = await starter.StartNewAsync(nameof(SearchOrchestration), instanceId);
        }

        [FunctionName(nameof(SearchOrchestration))]
        public static async Task SearchOrchestration(
            [OrchestrationTrigger]IDurableOrchestrationContext context,
            ILogger logger)
        {
            try
            {
                await context.CallActivityAsync(nameof(SearchPartIndexFunctionActivity), null);

                await context.CallActivityAsync(nameof(SearchProductIndexFunctionActivity), null);
            }
            catch (FunctionFailedException ex)
            {
                logger.LogError(ex, $"Search index orchestration failed.");
            }
        }

        [FunctionName(nameof(SearchPartIndexFunctionActivity))]
        public static async Task SearchPartIndexFunctionActivity(
            [ActivityTrigger]string input,
            ExecutionContext context,
            ILogger logger)
        {
            logger.LogInformation("Started SearchPartIndexFunctionActivity...");

            var busLogic = new SearchPartIndexFunctionBase(context, logger);
            await busLogic.UpdateIndexAndData();

            logger.LogInformation("Finished SearchPartIndexFunctionActivity successfully.");
        }

        [FunctionName(nameof(SearchProductIndexFunctionActivity))]
        public static async Task SearchProductIndexFunctionActivity(
            [ActivityTrigger]string input,
            ExecutionContext context,
            ILogger logger)
        {
            logger.LogInformation("Started SearchProductIndexFunctionActivity...");

            var busLogic = new SearchProductIndexFunctionBase(context, logger);
            await busLogic.UpdateIndexAndData();

            logger.LogInformation("Finished SearchProductIndexFunctionActivity successfully.");
        }
    }

Answer 1

问题似乎来自您的[DurableClient(TaskHub = "%TaskHub:Name%")]

其他代码没问题。

函数在我这一边像这样工作：

    public static void TimerStart(
        [TimerTrigger("*/1 * * * * *")]TimerInfo myTimer,
        [DurableClient]IDurableOrchestrationClient starter,
        ILogger log)
    {
        // Function input comes from the request content.

        log.LogInformation($"==================================Started orchestration with ID");

    }

Answer 2

出于历史目的

我部署到生产环境中，一切运行正常。当我创建DEV插槽时出现了问题。

有时生产功能“说”该任务已成功执行。但是，什么也没做。然后，该功能将重新启动，一切将再次正常运行。但是问题总是返回，对我来说，协调器在调用StartNew时没有运行

最后，我发现，由于DEV和PROD环境共享同一个表存储，因此DEV环境在处理生产请求时很忙为了解决这个问题，我必须为每个插槽部署具有不同集线器名称的host.json

Azure持久功能编排触发器不会触发
