Azure Functions（Http触发器）开始随机抛出TaskCancelled异常。

c#.netazure-functionsazure-http-trigger
6

我该如何解决这个问题？

  • 我有几个使用以下触发器签名的Azure函数 [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post")。

  • 这些函数运行在消耗计划上。

  • 它们每天会被触发2-3次。

这个函数偶尔无法触发，并出现以下异常：

Azure的诊断显示任务在调用工作进程之前被取消。 Diagnostic

public class AlpacaSample 
{
    private ILogger logger;

    public AlpacaSample(ILoggerFactory loggerFactory)
    {
        this.logger = loggerFactory.CreateLogger<AlpacaSample>();
    }

    [Function("AlpacaSample")]
    public async Task<HttpResponseData> Run([HttpTrigger(AuthorizationLevel.Anonymous, "get", "post")] HttpRequestData req)
    {
        try
        {
            this.requestData = req;
            string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
            var message = $"Received a trigger {requestBody}";
            this.logger.LogInformation(message);

            // Business logic removed for brevity 


            return await this.CreateStringResponse(req, "All Good");
        }

        catch (Exception ex)
        {
            string responseMessage =
                   $"Error occurrend while handling the message. Error: {ex.Message} \n {ex}";
            this.logger.LogError(responseMessage);
            return await this.CreateStringResponse(req, responseMessage);
        }


    }

    private async Task<HttpResponseData> CreateStringResponse(HttpRequestData req, string msg, HttpStatusCode httpStatusCode = HttpStatusCode.OK)
    {
        var res = HttpResponseData.CreateResponse(req);
        res.StatusCode = httpStatusCode;
        await res.WriteStringAsync(msg);
        return res;
    }
}

请展示相关代码 - Charlieface
请告诉我你要找的代码是什么。执行甚至没有进入我的代码内部。我在原始问题中添加了一些来自Azure诊断的快照。 - AGCodes
嗯，我不太清楚，看起来好像是Azure的内部触发器代码进入了一个无限循环。也许应该向支持团队提出此问题。另外注意一下，string requestBody = await new StreamReader(req.Body).ReadToEndAsync();你需要像这样释放读取器：using var sr = new StreamReader(req.Body); string requestBody = await sr.ReadToEndAsync(); - Charlieface
是的，我一直没有找到一个合适的论坛来解决这个问题。我确实有一个使用包装器来读取操作的方法。我只是在这篇帖子中去掉了多余的覆盖物。 - AGCodes
可能是个死胡同，但你试过将其作为WebJob发布吗（在应用服务应用程序下）？ - Ivan Gechev

错误是由于在五月底对底层Azure运行时版本的更新导致的。临时解决方法是将Azure运行时固定为4.17.3版本。这个信息是由Azure技术支持提供的。
版本4.17.3似乎已经消失了，https://github.com/Azure/app-service-announcements/issues我们正在使用4.22.0.20804，并且也遇到了这些问题。 - Jonas

是的，这个问题对我来说也出现了。 - AGCodes
我有同样的问题，但只在我的本地环境中出现。 - David P
