我有Azure Service Bus中某个主题的订阅者。我经常看到间歇性错误返回如下：
MassTransit.Azure.ServiceBus.Core.Transport.ReceiveTransport错误：0：ReceiveTransport错误：sb：//###，System.AggregateException：发生一个或多个错误。 （发生一个或多个错误。（数字必须为非负数，并且小于或等于Int32.MaxValue或-1。 参数名称：dueTime））---> System.AggregateException：发生一个或多个错误。 （数字必须为非负数，并且小于或等于Int32.MaxValue或-1。 参数名称：dueTime）---> System.ArgumentOutOfRangeException：数字必须为非负且小于或等于Int32.MaxValue或-1。 参数名称：dueTime
我无法看到如何/在何处设置dueTime来防止这种情况的发生。订户大部分时间都在处理消息。
是否可以通过MassTransit设置DueTime？
发布者：
await _busControl.Publish(new ConfigurationReloaded(),
context => context.TimeToLive = new TimeSpan(0, 0, 10, 0), cancellationToken);
接收器：
serviceBusHost.ConnectSubscriptionEndpoint<ConfigurationReloaded>($"{_serviceBusOptions.SubscriberName}_{_myUniqueSubscriberName}", x =>
{
x.AutoDeleteOnIdle = _serviceBusOptions.TimeToRemoveOnIdle;
x.Handler<ConfigurationReloaded>(context =>
{
this.Load();
return Task.CompletedTask;
});
});

服务集合扩展以添加大众运输：
public static IServiceCollection AddMassTransit(
this IServiceCollection collection, string serviceBusHost, string serviceBusKeyName, string serviceBusSharedAccessKey)
{
collection.AddSingleton(Bus.Factory.CreateUsingAzureServiceBus(cfg =>
{
var host = cfg.Host(
serviceBusHost,
h =>
{
h.SharedAccessSignature(s =>
{
s.KeyName = serviceBusKeyName;
s.SharedAccessKey = serviceBusSharedAccessKey;
});
});
collection.AddSingleton(host);
}
));
collection.AddSingleton<IHostedService, BusService>();
return collection;
}
答案 0 :(得分：1)
我也一直在遭受这个问题的困扰。调试后，我认为我找到了问题。 .net核心服务总线库中的默认值太低。
在ShareAccessSignature配置方法中，将TokenTimeToLive设置为合理的值似乎可以解决。
sbcfg.SharedAccessSignature(sas =>
{
sas.TokenTimeToLive = TimeSpan.FromMinutes(20);
sas.KeyName = Configuration.GetValue<string>("ServiceBus:KeyName");
sas.SharedAccessKey = Configuration.GetValue<string>("ServiceBus:AccessKey");
});
有关信息，这些是github中与此默认行为有关的相关（开放）问题。
