Azure Service Bus使用消息内容或消息头数据调度消息取消 [英] Azure Service Bus Schedules Messages cancellation using the message content or message header data

问题描述

我想使用消息内容取消服务总线queue/topic中的计划消息.

I would like to cancel the scheduled messages in the service bus queue/topic using the message content.

例如:queue/topic中的预定消息将类似于{UserName:'Scott', Test: 'This is test msg'}

e.g: the scheduled message in queue/topic will be like this {UserName:'Scott', Test: 'This is test msg'}

我想使用UserName

注意:我没有保存取消令牌，可以用来取消计划的消息.

Note: I am not saving the cancellation token, which i can use to cancel the scheduled message.

推荐答案

AFAIK，无法基于用户属性取消计划的消息.您唯一可以取消预定消息的方法是通过它的SequenceNumber属性.

AFAIK, it is not possible to cancel a scheduled message based on a user property. Only way you could cancel a scheduled message is by it's SequenceNumber property.

感谢肖恩·费尔德曼(Sean Feldman)的 blog post 关于同一主题，如果您知道邮件的SequenceNumber属性，请按照以下方法取消预定的邮件:

Thanks to Sean Feldman for his blog post on the same topic, here's how you can cancel a scheduled message if you know the message's SequenceNumber property:

var sequenceNumber = await queueClient.ScheduleMessageAsync(message, DateTimeOffset.UtcNow.AddSeconds(300)).ConfigureAwait(false);
await queueClient.CancelScheduledMessageAsync(sequenceNumber).ConfigureAwait(false);
