在频道中发送 chatMessage

命名空间：microsoft.graph

在指定频道中发送新的 chatMessage。

注意：

• 建议不要通过标准创建消息流使用此 API 进行数据迁移。 对于数据迁移方案，请改用 导入消息 流。
• 将 Microsoft Teams 用作日志文件违反了 使用条款 。 仅发送人们将阅读的消息。

此 API 可用于以下国家级云部署。

全局服务	美国政府 L4	美国政府 L5 (DOD)	由世纪互联运营的中国
✅	✅	✅	✅

权限

为此 API 选择标记为最低特权的权限。 只有在应用需要它时，才使用更高的特权权限。 有关委派权限和应用程序权限的详细信息，请参阅权限类型。 要了解有关这些权限的详细信息，请参阅 权限参考。

权限类型	最低特权权限	更高特权权限
委派（工作或学校帐户）	ChannelMessage.Send	Group.ReadWrite.All
委派（个人 Microsoft 帐户）	不支持。	不支持。
应用程序	Teamwork.Migrate.All	不可用。

注意

仅支持向后兼容 Group.ReadWrite.All 权限。 建议更新解决方案，以使用上表中列出的替代权限，并避免今后使用这些权限。

• 仅支持 迁移应用程序权限。 将来，Microsoft 可能要求你或你的客户根据导入的数据量支付其他费用。

示例 2：导入邮件

以下示例演示如何导入消息。 有关详细信息，请参阅 使用 Microsoft Graph 将消息导入Microsoft Teams 聊天和频道。

注意：此方案需要权限范围 Teamwork.Migrate.All 。 目标通道必须处于迁移模式。 from 属性将消息特性化为与经过身份验证的应用程序位于同一租户中的用户。 createdDateTime 值必须晚于通道 createdDateTime，并且不能在将来使用。

重要

createdDateTime 在目标通道内必须唯一到毫秒。 如果存在具有相同 createdDateTime 的消息，则请求失败并出现 409 Conflict。 调整 createdDateTime 并重试。 有关详细信息，请参阅 使用 Microsoft Graph 将消息导入Microsoft Teams 聊天和频道。
