指定公共交通中的发布超时

Specify Publish timeouts in mass transit(指定公共交通中的发布超时)

问题描述

在使用 MassTransit 库发布消息时，是否可以指定超时值.消息代理宕机时如何处理场景.现在看来 Publish 调用无限期地等待.控制这些行为会很好.我们应该依赖取消令牌吗?超时实现可能会更好.

Is there a way to specify timeout value when publishing messages using the MassTransit Library. How to handle scenarios when message broker goes down. Now it seems that Publish call waits indefinitely. It would be nice to control these behavior. Should we rely on cancellation token? Timeout implementation might be better.

推荐答案

您可以将 CancellationToken 传递给 Publish.如果取消，将抛出 OperationCanceledException.如果你想使用超时，你可以创建一个带有超时的CancellationTokenSource.

You can pass a CancellationToken to Publish. If canceled, an OperationCanceledException will be thrown. If you want to use a timeout, you can create a CancellationTokenSource with a timeout.

using var source = new CancellationTokenSource(TimeSpan.FromSeconds(30));

await bus.Publish(message, source.Token);
