c#如何使用microsoft graph api获取office 365用户照片

Question

我希望能够在 Azure 活动目录中获取所有用户的 office365 照片。

现在我可以使用图形 SDK 获取当前用户的电子邮件

GraphServiceClient graphClient = SDKHelper.GetAuthenticatedClient();

public async Task<string> GetMyEmailAddress(GraphServiceClient graphClient)
    {          
        User me = await graphClient.Me.Request().Select("mail,userPrincipalName").GetAsync();
        return me.Mail ?? me.UserPrincipalName;
    }

但我不知道如何将集成在得到照片部分来自https://graph.microsoft.io/en-us/docs/api-reference/v1.0/api/profilephoto_get到代码。

任何帮助或代码示例表示赞赏！

Answer 1

这有助于获取图像

 GraphServiceClient graphServiceClient = GetAuthenticatedGraphServiceClient();

 Stream photo = await graphServiceClient.Me.Photo.Content.Request().GetAsync();

 if (photo != null)
 {
     MemoryStream ms = new MemoryStream();
     photo.CopyTo(ms);
     byte[] buffer = ms.ToArray();
     string result = Convert.ToBase64String(buffer);
     string imgDataURL = string.Format("data:image/png;base64,{0}", result);
     ViewBag.ImageData = imgDataURL;
 }
 else
 {
      ViewBag.ImageData = "";
 }

graphClient.Me.Photo.Content您可以使用它将检索流中照片的二进制数据来获取照片：

 public async Task GetPictureAsync()
 {
     GraphServiceClient graphClient = GetGraphServiceClient();

     var photo = await graphClient.Me.Photo.Content.Request().GetAsync();
     using (var fileStream = File.Create("C:\\temp\\photo.jpg"))
     {
         photo.Seek(0, SeekOrigin.Begin);
         photo.CopyTo(fileStream);
     }
 }
