获取 Microsoft Teams 的系统消息
Microsoft Teams 通过使用 Microsoft Graph API 为事件生成系统消息。 事件包括向聊天添加成员、更新团队名称和更新频道说明。 通过系统消息,调用方可以深入了解团队、频道或聊天中发生的事件。
Microsoft Graph 将系统消息作为 chatMessage GET 操作和 聊天和频道消息的更改通知的一部分公开。
系统消息显示为 chatMessage 对象。
在这种情况下,messageType 属性设置为 systemEventMessage
,并且 eventDetail 属性提供事件详细信息。
以下 GET 操作支持系统消息:
- GET /teams/{team-id}/channels/{channel-id}/messages
- GET /teams/{team-td}/channels/{channel-id}/messages/{message-id}
- GET /chats/{chat-id}/messages
- GET /chats/{chat-id}/messages/{message-id}
有关详细信息,请参阅 chatMessage。
以下更改通知支持系统消息:
- 订阅频道中的消息 - /teams/{team-id}/channels/{channel-id}/messages
- 订阅聊天中的消息 - /chats/{chat-id}/messages
有关详细信息,请参阅 更改消息的通知。
备注
适用于团队的系统消息在主频道中发布。
以下 JSON 示例显示每个受支持事件类型的响应。
