Azure 服务总线 SendAsync 不在控制台应用程序中发送消息

Question

 For some reason, I cannot send the message to the Service Bus Queue in my web job. Is this a limitation of a webjob that I cannot send an async request? I've tried downgrading and upgrading all the packages and even changing the .net framework, but nothing works.

规格： 1. 网络框架 4.6.1 2. Microsoft.Azure.Amqp 2.4.3 3. Microsoft.Azure.ServiceBus 4.1.1 4. Microsoft.Azure.WebJobs 2.2.0 5. Microsoft.Azure.WebJobs.核心2.2.0 6. Newtonsoft.Json 12.0.3 7.WindowsAzure.Storage9.3.3

代码：

 public bool AddoQueue(string message)
        {
            _sendMessage.SendMessageToQueue(message);
            return true;
        }



        static IQueueClient queueClient;

public async Task<bool> SendMessageToQueue(string message)
        {
            try
            {
                queueClient = new QueueClient(Configurator.GetConfigSettings("SBConnectionString"), Configurator.GetConfigSettings("QueueName"));

                var messageObj = new Message(Encoding.UTF8.GetBytes(message))
                {
                    TimeToLive = TimeSpan.FromDays(6),
                    PartitionKey = message
                };

                await queueClient.SendAsync(messageObj);

                return true;
            }
            catch (Exception e)
            {
                Console.Write(e);
                return false;
            }
        }

因为您的 SendMessageToQueue 是一个 async 函数，您需要等待它完成。

一种可能的解决方案是更改以下代码行：

_sendMessage.SendMessageToQueue(message);

到

_sendMessage.SendMessageToQueue(message).GetAwaiter().GetResult();;

其他解决方案是将调用方法 AddoQueue() 设置为异步（以及所有其他调用此异步的方法。在这种情况下，您的代码将是

await _sendMessage.SendMessageToQueue(message);
