我正在尝试获取属于特定事件的所有eventMessages。但是我无法。
我正在用me/messages查询$expand=microsoft.graph.eventMessage/event，并尝试根据这种关系进行过滤：
https://graph.microsoft.com/v1.0/me/messages?$expand=microsoft.graph.eventMessage/event&filter=event/id eq 'eventID'
但是，出现以下错误
{
"error": {
"code": "RequestBroker--ParseUri",
"message": "Could not find a property named 'event' on type 'Microsoft.OutlookServices.Message'.",
"innerError": {
"request-id": "cb211061-802b-4657-a191-f06c449897d1",
"date": "2019-05-16T14:01:43"
}
}
}
但是请注意their example的事件扩展消息，在API返回时有一个事件属性（请参见下面返回的JSON）。
HTTP/1.1 200 OK

我希望上面的过滤器会使API仅返回属于该事件的消息。但是，它给了我400，我认为可能是由于在这种特定情况下如何过滤的语法所致，但是我在他们的文档中找不到关于此的任何信息。有人知道如何在图形API上执行这种过滤吗？
