观看对新主题的请求会暂停向现有主题的推送通知 [英] watch request to new topic pauses push notifications to existing topic

问题描述

我在一个项目下的Google Cloud Pub/Sub帐户中配置了两个主题，每个主题都有一个订阅.

I've configured two topics in my Google Cloud Pub/Sub account, each with a single subscription, under a single project.

当我在收件箱中调用watch()并将主题1传递给监视请求时，我会收到推送通知到所需的端点.当我在收件箱中为 topic 2 调用watch()时，我收到与主题2关联的终结点的推送通知，但是推送通知不再针对主题1 到达.

When I call watch() on my inbox, passing topic 1 to the watch request, I receive push notifications to my desired endpoint. When I call watch() on my inbox for topic 2, I receive push notifications for the endpoint tied to topic 2, but push notifications stop arriving for topic 1.

对于给定项目，似乎只有一个主题可以在任何给定时间针对给定收件箱发出通知.任何人都可以帮助确认是否是这种情况吗?

It appears that only a single topic can push out notifications for a given inbox at any given time, for a given project. Can anyone help confirm whether this is the case?

我在 Gmail推送通知的文档中找不到任何内容注意到了这一限制.每当我再次调用watch()时(从主题1订阅到主题2，再调用watch()，反之亦然)，我都会从API收到成功的响应，但是关于我之前订阅的主题的通知仍然停止.对于watch()请求，我也处于到期窗口之内.

I can't find anything in the documentation for Gmail push notifications that notes this limitation. I receive a successful response from the API every time I call watch() again (subscribed to topic 1 -> call watch() for topic 2, and vice versa), but notifications still stop for the topic I was previously subscribed to. I'm also well within the expiry window for the watch() requests.

任何建议/指导将不胜感激！

Any advice / direction would be much appreciated!

推荐答案

每个开发人员只能在给定的邮箱上进行一次监视设置.未明确指定，但API调用表示watch()调用用于设置或更新手表: https://developers.google.com/gmail/api/v1/reference/users/watch (在REST中，没有"List Watches"，"watch.id"唯一标识符等可以允许多个手表使用的内容.一个手表是一个单例资源.)

Each developer can only have one watch setup on a given mailbox. It's not specified explicitly but the API call says the watch() call is for either setting up or updating the watch: https://developers.google.com/gmail/api/v1/reference/users/watch (there's no "List Watches", "watch.id" unique identifier, etc that would be required in REST for multiple watches to be allowed. A watch is a singleton resource.)
