调用 https://graph.microsoft.com/v1.0/users/<ID 日历>/日历/日历视图？ 不返回约会，并且有约会

Question

自昨天以来，对图形 API 的调用无法正常工作：

https://graph.microsoft.com/v1.0/users/<my calendar ID>/calendar/calendarView?startDateTime=2019-10-04T19:10:24.0000000&endDateTime=2019-11-03T19:10:24.0000000&top=100

返回 0 个事件 - 约会，并且有约会要列出

该电话直到昨天工作正常，每 8 分钟，自上个月以来 24x7

全天候：

// List events.
string fini = string.Format("{0}-{1}-{2}T{3}:{4}:{5}.0000000",                                                  
UpDateTime.Year.ToString("0000"),                                                    
UpDateTime.Month.ToString("00"),                                                    
UpDateTime.Day.ToString("00"),                                                    
UpDateTime.Hour.ToString("00"),                                                    
UpDateTime.Minute.ToString("00"),                                              
UpDateTime.Second.ToString("00")
);
string ffin = string.Format("{0}-{1}-{2}T{3}:{4}:{5}.0000000", // 
EndTime.Year.ToString("0000"),
EndTime.Month.ToString("00"),
EndTime.Day.ToString("00"),
EndTime.Hour.ToString("00"),
EndTime.Minute.ToString("00"),
EndTime.Second.ToString("00")
);
String _requestURI = _GraphURLEvents.Replace("events", "calendarView") + string.Format("?startDateTime={0}&endDateTime={1}&top=100", fini, ffin);
_requestURI = String.Format(_requestURI, _userId);
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, _requestURI);
//Authentication token
request.Headers.Add("Prefer", "outlook.timezone="Romance Standard Time"");
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", System.Web.HttpUtility.UrlEncode(access_token));
HttpClient client = new HttpClient();
var response = await client.SendAsync(request)
var returnURL = await 
response.Content.ReadAsStringAsync();

获取善意呼叫返回：

}}
StatusCode: OK
Version: {1.1}

该调用必须返回类似以下内容：

https://learn.microsoft.com/en-us/graph/api/user-list-calendarview?view=graph-rest-1.0&tabs=http
HTTP/1.1 200 OK
Content-type: application/json
Content-length: 354
{
"value": [
{
"originalStartTimeZone": "originalStartTimeZone-value",
"originalEndTimeZone": "originalEndTimeZone-value",
"responseStatus": {
"response": "",
"time": "datetime-value"
},
"iCalUId": "iCalUId-value",
"reminderMinutesBeforeStart": 99,
"isReminderOn": true
}
]
}

。从昨天开始，结果是：

{"@odata.context":"https://graph.microsoft.com/v1.0/$metadata#users('<calendarId>')/calendar/calendarView","value":[]}

Answer 1

根据我的测试，网址应该是：

1. 获取特定用户的日历

https://graph.microsoft.com/v1.0/users/<user_id>/calendar/calendarView?startDateTime=2019-10-06T16:00:00Z&endDateTime=2019-10-10T16:00:00Z&top=100

或

https://graph.microsoft.com/v1.0/users/<user_id>/calendars/<calendar_id>/calendarView?startDateTime=2019-10-06T16:00:00Z&endDateTime=2019-10-10T16:00:00Z&top=100

2.获取我的日历

https://graph.microsoft.com/v1.0/me/calendar/calendarView?startDateTime=2019-10-06T16:00:00Z&endDateTime=2019-10-10T16:00:00Z&top=100

或

https://graph.microsoft.com/v1.0/me/calendars/<calendar_id>/calendarView?startDateTime=2019-10-06T16:00:00Z&endDateTime=2019-10-10T16:00:00Z&top=100

我可以从上面的网址获得成功的回复。
