在UWP中使用Microsoft Graph API下载会议邀请中发送的附件,可以按照以下步骤进行:
string clientId = "Your_Client_Id";
string clientSecret = "Your_Client_Secret";
string[] scopes = { "https://graph.microsoft.com/.default" };
ConfidentialClientApplication app = new ConfidentialClientApplication(clientId, "https://login.microsoftonline.com/your_tenant_id");
AuthenticationResult authResult = await app.AcquireTokenForClientAsync(scopes);
string accessToken = authResult.AccessToken;
GET /me/events/{event_id}
接口获取会议邀请的详细信息,包括附件。GraphServiceClient graphClient = new GraphServiceClient(new DelegateAuthenticationProvider((requestMessage) =>
{
requestMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
return Task.FromResult(0);
}));
string eventId = "Your_Event_Id";
Event meetingEvent = await graphClient.Me.Events[eventId].Request().Expand("attachments").GetAsync();
GET /me/events/{event_id}/attachments/{attachment_id}/$value
接口下载附件。foreach (var attachment in meetingEvent.Attachments)
{
if (attachment.ContentType.StartsWith("file"))
{
string attachmentId = attachment.Id;
Stream attachmentStream = await graphClient.Me.Events[eventId].Attachments[attachmentId].Content.Request().GetAsync();
// 处理附件流,例如保存到本地文件
// ...
}
}
以上是在UWP中使用Microsoft Graph API下载会议邀请中发送的附件的步骤。通过使用Microsoft Graph SDK和相关API,可以方便地与Microsoft Graph进行交互,实现各种功能,包括会议邀请的附件下载。
