  《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

  

  上面三个Role的区别:

  (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("leiservicebus01.servicebus.chinacloudapi.cn", credential);

//这里我用的队列名称为queue01
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.");
    }
}

try
{
    // 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.");
}
finally
{
    // 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");
Console.ReadKey();
