Question

我有一个使用Webjob扩展名sdk的webjob，以及一个手动触发并正在读/写服务总线的函数。

发送邮件时似乎挂起了。

这是相关代码：

JobHostConfiguration config = new JobHostConfiguration
            {
                StorageConnectionString = decryptedStorageConnectionString,
                DashboardConnectionString = decryptedDashboardConnectionString,
            };
            config.UseTimers();
            var host = new JobHost(config);

            host.CallAsync(typeof(Program).GetMethod(nameof(myJob)));

            // The following code ensures that the WebJob will be running continuously
            host.RunAndBlock();

[NoAutomaticTrigger]
        public void myJob(TextWriter log)
        {
...
 this.Client = TopicClient.CreateFromConnectionString(connection, ConstantStrings.IncidentResponseTopicName);
this.Client.Send(args);

}

我收到以下错误：

当我使用常规的Azure webjob时，一切都运行良好。当我将代码移动到Azure Webjob SDK时，这个挂起就开始了。另一个有趣的事情是，在本地计算机上运行时，一切似乎都运行良好，只有在将代码部署到Azure Webjobs时才会发生这种情况

任何想法???

根据您的代码，我假设您正在使用Azure WebJobs SDK Extensions > TimerTrigger来安排其他工作，并在JobHost时手动调用myJob函数来从/向服务总线读/写消息启动。

System.TimeoutException：请求操作未在分配的超时00：01：09.9496489内完成。分配给此操作的时间可能是较长超时的一部分。

正如官方document中提到的关于服务总线消息TimeoutException：

TimeoutException表示用户启动的操作所花费的时间超过了操作超时。   您应该检查ServicePointManager.DefaultConnectionLimit属性的值，因为达到此限制也会导致TimeoutException。

服务器未在OperationTimeout控制的指定时间内响应请求的操作。

我认为您可以尝试增加OperationTimeout并按如下方式添加重试逻辑来构建TopicClient：

var builder = new ServiceBusConnectionStringBuilder("{ServicesBusConnectionString}")
{
    OperationTimeout = TimeSpan.FromMinutes(10)
};
var messagingFactory = MessagingFactory.CreateFromConnectionString(builder.ToString());
TopicClient topicClient = messagingFactory.CreateTopicClient("{TopicName}");
topicClient.RetryPolicy = new RetryExponential(
             TimeSpan.Zero,
             TimeSpan.FromMinutes(5),
             2);
topicClient.Send("{BrokeredMessage}");

使用azure webjob SDK时，TopicClient会发送挂起
