调用Calendar getSchedule API无法获取会议室事件主题、位置等信息

我正尝试通过服务主体或应用访问令牌，调用Microsoft Graph的Calendar getSchedule API，按Room ID获取Teams Rooms的事件信息。应用需要获取特定日期的事件详情，包括主题（subject）、地点（location）、开始时间和结束时间。

我调用的POST请求地址为：https://graph.microsoft.com/v1.0/users/{user_id/UserPrincipalName}/calendar/getSchedule，其中UserPrincipalName设为ls-meetingroom-gothamcity@test.com。

请求负载 #

{
    "schedules": ["ls-meetingroom-gothamcity@test.com", "ls-meetingroom-wakanda@test.com"],
    "startTime": {
        "dateTime": "2023-06-27T00:00:00",
        "timeZone": "India Standard Time"
    },
    "endTime": {
        "dateTime": "2023-06-27T23:59:59",
        "timeZone": "India Standard Time"
    },
    "availabilityViewInterval": 30
}

遇到的问题 #

当前响应仅能返回事件的开始时间、结束时间和状态，无法获取主题（subject）、**地点（location）**等所需的事件详情。
