azure service bus 与dynamics 365 集成

1  在azure 上创建一个 azure service bus

  步骤请参考 

 

 

 

 

 2 创建完service bus后,配置一个消息队列

3 获取 消息队列的连接字符串

4 使用Dynamics 365 插件注册工具,注册一个 Service Endpoint,将上一步的连接字符串放一起保存

 

 

 

5 注册一个消息 ,使用4 步创建service endpoint 

 

 

 

这样就完成了在azure service bus 消息队列上查看CRM下发的消息。也可以使用代码监听消息

 

 static async Task ProcessMessagesAsync(Message message, CancellationToken token)
        {


            // Process the message
            Console.WriteLine($"Received message: SequenceNumber:{message.SystemProperties.SequenceNumber} Body:{Encoding.UTF8.GetString(message.Body)}");



            if (message.ContentType == "application/msbin1")
            {
                RemoteExecutionContext context = message.GetBody<RemoteExecutionContext>();
            }
            else if (message.ContentType == "application/json")
            {
                //string jsonBody = new StreamReader(receivedMessage.GetBody<Stream>(), Encoding.UTF8).ReadToEnd();  
                RemoteExecutionContext contextFromJSON = message.GetBody<RemoteExecutionContext>(
                    new DataContractJsonSerializer(typeof(RemoteExecutionContext)));
            }
            else if (message.ContentType == "application/xml")
            {
                //string xmlBody = new StreamReader(receivedMessage.GetBody<Stream>(), Encoding.UTF8).ReadToEnd();  
                RemoteExecutionContext contextFromXML = message.GetBody<RemoteExecutionContext>(
                    new DataContractSerializer(typeof(RemoteExecutionContext)));
            }
            // Complete the message so that it is not received again.
            // This can be done only if the queueClient is created in ReceiveMode.PeekLock mode (which is default).
            await queueClient.CompleteAsync(message.SystemProperties.LockToken);

            // Note: Use the cancellationToken passed as necessary to determine if the queueClient has already been closed.
            // If queueClient has already been Closed, you may chose to not call CompleteAsync() or AbandonAsync() etc. calls 
            // to avoid unnecessary exceptions.
        }

 

整个类如下 ,需要引用nuget 包
