Azure Service Bus主题多个侦听器接收相同的消息 [英] Azure Service Bus Topic multiple listeners receive same message

问题描述

Hi Team，

我有一种情况，我正在尝试实现发布/订阅模式。

I have a situation where i am trying to implement pub/sub pattern.

使用Azure我是如果两个客户订阅同一主题，则发布消息并进入客户端。订阅只有其中一个是收到其他客户端没有得到的消息。

Using Azure i am publishing message and coming to client if two clients are subscribed to same topic & subscription only one of it is getting message other client is not getting.

简单来说：

我正在广播消息并且订阅了两个人到我的主题。当我广播消息时，只有一个人正在收到其他人没有得到的消息。下面是示例代码。

I am broadcasting message and two persons are subscribed to my Topic. When i broadcast message only one person is getting that message other doesn't get. Below is sample code.

 subscriptionClient = new SubscriptionClient(sbConnectionString, sbTopic, sbSubscription);

                var messageHandlerOptions = new MessageHandlerOptions(ExceptionReceivedHandler)
                {
                    MaxConcurrentCalls = 100000,
                    AutoComplete = false,
                };
                subscriptionClient.RegisterMessageHandler(ReceiveMessagesAsync, messageHandlerOptions);

在这种情况下，如果我遗漏了任何内容或Azure服务主题是错误的选项，请告诉我。

Please let me know if i am missing anything or Azure Service topic is wrong option in this case.

我试过AMPS它像魅力广播一样对所有订阅者

I tried AMPS it works like charm broadcasting to all subscribers

推荐答案

嗨  skalvag

给定
本节文档，您的用例与服务公交车主题似乎是有效的&非常好。实际上，我只是能够测试和通过使用
Service Bus Explorer 确认它是这样工作的，其中我在所有订阅中收到消息的副本。话虽如此，我怀疑你可能只需要添加一个过滤器：

Given this section of the documentation, your use-case with Service Bus Topics seems valid & perfectly fine. Actually, I was just able to test & confirm that it works that way by using Service Bus Explorer where i was receiving copies of the message across all subscriptions. With that said, i'm suspecting that you might just need to add a filter:

subscriptionClient.AddRuleAsync("default", new SqlFilter("1=1"));
