尝试获取登录用户的个人资料图像,然后将其保存在服务器上。
此代码来自 Startup.Auth.cs
AuthorizationCodeReceived = async (context) =>
{
var code = context.Code;
ClientCredential credential = new ClientCredential(clientId, appKey);
string signedInUserID = context.AuthenticationTicket.Identity.FindFirst(ClaimTypes.NameIdentifier).Value;
string userObjectID = context.AuthenticationTicket.Identity.FindFirst("http://schemas.microsoft.com/identity/claims/objectidentifier").Value;
AuthenticationContext authContext = new AuthenticationContext(Authority, new ADALTokenCache(signedInUserID));
AuthenticationResult result = await authContext.AcquireTokenByAuthorizationCodeAsync(
code, new Uri(HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Path)), credential, graphResourceId);
AuthenticationResult authenticationResult = await authContext.AcquireTokenSilentAsync(graphResourceId, credential, new UserIdentifier(userObjectID, UserIdentifierType.UniqueId));
Uri servicePointUri = new Uri(graphResourceId);
Uri serviceRoot = new Uri(servicePointUri, tenantId);
ActiveDirectoryClient activeDirectoryClient = new ActiveDirectoryClient(serviceRoot, async () => await Task.FromResult(result.AccessToken));
var res = await activeDirectoryClient.Users
.Where(u => u.ObjectId.Equals(userObjectID))
.ExecuteAsync();
IUser user = res.CurrentPage.ToList().First();
var image = await user.ThumbnailPhoto.DownloadAsync();
}
等待 user.ThumbnailPhoto.DownloadAsync() 抛出此错误
{"odata.error":{"code":"Request_ResourceNotFound","message":{"lang":"en","value":"Resource 'thumbnailPhoto' does not exist or one of its queried reference-property objects are not present."}}}
最佳答案
根据错误信息,问题的主要原因可能是没有为用户设置缩略图。当我在为用户设置缩略图之前运行代码时,我可以重现此问题。那么该代码对我来说效果很好。
您可以通过登录新的azure protal来检查是否设置了缩略图,并比较右上角的图像,如下图所示:
我通过 PowerShell 从本地 Active Directory 设置它,并通过 Azure AD 连接将其同步到 Azure AD:
Set-ADUser user1 -Replace @{thumbnailPhoto=([byte[]](Get-Content "C:\Users\UserName\Desktop\me.jpg" -Encoding byte))}
关于c# - Asp.Net Mvc 5 Azure Active Directory 获取用户配置文件图像并将其保存在服务器上,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/39518324/
