Question

我正在尝试创建Azure Function并在本地对其进行测试。我有MSFT VS2017 + Azure开发工具。我已经使用TimerTrigger创建了Azure Function项目。我没有更改默认模板中的任何内容。

函数是：

 SELECT  
   i.IncidentID, 
   CASE WHEN CHARINDEX('asda', sa.AddressStreet) > 0 THEN 'true' else 'false' end AS 'asda' 
FROM Incident i
JOIN IncidentSubject isu ON isu.IncidentID = i.IncidentID
JOIN SubjectAddress sa ON sa.SubjectID = isu.SubjectID
WHERE i.Section <> 0 AND (i.Section & 255 <> 0)

运行时：

    [FunctionName("Function1")]
    public static void Run([TimerTrigger("0 */5 * * * *")]TimerInfo myTimer, ILogger log)
    {
        log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
    }

，它在这里失败：

有人遇到这个问题吗？我应该怎么做才能运行默认的Azure功能模板？

Answer 1

最有可能的是，如果您只是尝试运行默认值，则问题出在您的local.settings.json中。

如果打开文件，您将拥有：

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet"
  }
}

对吗？

如果是这样，则需要将存储连接字符串放在AzureWebJobsStorage中。它看起来像：

DefaultEndpointsProtocol=https;AccountName=<account_name>;AccountKey=<account_key>;EndpointSuffix=core.windows.net

然后该脚本应该运行无误。

Answer 2

我无法解决您的问题。我正在使用Visual Studio 2017 + Azure开发工具。我也有相同版本的Core Tools v2.0.12438.0。

以下是创建时间触发功能的文档：https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-scheduled-function。在计时器触发器中，您可以指定希望功能应用程序运行的频率。请注意，计划设置是一个六字段的CRON表达式（https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-timer#cron-expressions），例如，值'0 * / 1 * * * *'将计划您的函数每分钟运行一次。
