  《Windows Azure Platform 系列文章目录


  本文介绍的是,国内由世纪互联运维的Azure China



  在笔者之前的文档中,我们链接Service Bus,都是通过链接字符串Connection String来连接的。

  Windows Azure Service Bus (2) 队列(Queue)入门


  Azure Service Principal,类似AWS Application。是通过API或者SDK的方式,开发使用。

  我们可以通过Service Principal,来连接Azure Service Bus。

  1.首先我们先创建1个Service Principal,具体步骤:Azure AD (8) 创建配置应用程序和服务主体 (Application and Service Principal)

  2.在RBAC里,把Service Principal设置权限为Azure Service Bus Data Owner



  (1)Azure Service Bus Data Owner,具有全部权限(可以新增、或者删除Sevice Bus对象),对Service Bus数据可以读,也可以写

  (2)Azure Service Bus Data Receiver,对Service Bus操作只读(不能删除Service Bus对象),对Service Bus数据只读

  (3)Azure Service Bus Data Sender,对Service Bus操作只读(不能删除Service Bus对象),对Service Bus数据可以发送


  3.新建Visual Studio Console项目,使用下面的代码:


using Azure.Messaging.ServiceBus;
using Azure.Identity;
using Azure.Core;
using Microsoft.Identity.Client;

// name of your Service Bus queue
// the client that owns the connection and can be used to create senders and receivers
ServiceBusClient client;

// the sender used to publish messages to the queue
ServiceBusSender sender;

// number of messages to be sent to the queue
const int numOfMessages = 3;

// The Service Bus client types are safe to cache and use as a singleton for the lifetime
// of the application, which is best practice when messages are being published or read
// regularly.
// Set the transport type to AmqpWebSockets so that the ServiceBusClient uses the port 443. 
// If you use the default AmqpTcp, ensure that ports 5671 and 5672 are open.
var clientOptions = new ServiceBusClientOptions
    TransportType = ServiceBusTransportType.AmqpWebSockets

string tenantid = "";
string clientid = "";
string clientsecret = "";

ClientSecretCredentialOptions opts = new ClientSecretCredentialOptions()
    AuthorityHost = AzureAuthorityHosts.AzureChina

TokenCredential credential = new ClientSecretCredential(tenantid, clientid, clientsecret, opts);

//这里输入Sevice Bus的访问url,这里是我的演示环境
client = new ServiceBusClient("", credential);

sender = client.CreateSender("queue01");

// create a batch 
using ServiceBusMessageBatch messageBatch = await sender.CreateMessageBatchAsync();

for (int i = 1; i <= numOfMessages; i++)
    // try adding a message to the batch
    if (!messageBatch.TryAddMessage(new ServiceBusMessage($"Message {i}")))
        // if it is too large for the batch
        throw new Exception($"The message {i} is too large to fit in the batch.");

    // Use the producer client to send the batch of messages to the Service Bus queue
    await sender.SendMessagesAsync(messageBatch);
    Console.WriteLine($"A batch of {numOfMessages} messages has been published to the queue.");
    // Calling DisposeAsync on client types is required to ensure that network
    // resources and other unmanaged objects are properly cleaned up.
    await sender.DisposeAsync();
    await client.DisposeAsync();

Console.WriteLine("Press any key to end the application");
