是否可以为Azure函数.Net C#项目提供全局异常处理程序?

目前此功能不可用,您可以转到 feedback page

但是,您仍然可以将Azure功能与Application Insights结合使用,有关详细信息,请参阅以下文档: Monitor Azure Functions

我也在等待测试特性,但现在,我已经编写了日志/异常处理方面(AOP)。我有很多函数,但没有为异常处理编写一个try-catch。

我在用 MrAdvice

侧面

public class LoggerAspectAttribute : Attribute, IMethodAsyncAdvice
{
    public async Task Advise(MethodAsyncAdviceContext context)
    {
        ILog log = LogManager.GetLogger();
        RequestTelemetry requestTelemetry = new RequestTelemetry { Name = context.TargetType.Name };
        IOperationHolder<RequestTelemetry> operation = log.TelemetryClient.StartOperation(requestTelemetry);
        operation.Telemetry.Success = true;
        log.Info($"{context.TargetType.Name} trigger");

        try
        {
            await context.ProceedAsync(); // this calls the original method
        }
        catch (Exception ex)
        {
            operation.Telemetry.Success = false;
            log.Error(ex.Message, ex);
            throw;
        }
        finally
        {
            log.Info($"{context.TargetType.Name} completed.");
            log.TelemetryClient.StopOperation(operation);
        }
    }
}

public static class AlertFunction
{
    [LoggerAspect]
    [FunctionName("AlertFunction")]
    public static async Task Run([EventHubTrigger("%AlertEventHub%", Connection = "AlertEventHubConnection", ConsumerGroup = "%AlertEventHubConsumerGroup%")]EventData eventMessage,
        [Inject]IEventService eventService, [Inject]ILog log)
    {
        log.Verbose($"Event PartitionKey {eventMessage.PartitionKey}, Offset {eventMessage.Offset} and SequenceNumber {eventMessage.SequenceNumber}");
        string message = Encoding.UTF8.GetString(eventMessage.GetBytes());
        log.Verbose(message);
        await eventService.FilterAlertEventAsync(message);
    }
}

希望它能给你一些建议!
