オブジェクト モデルを使用して SharePoint サイトを作成しているときに、有名なエラー「このページのセキュリティ検証は無効です。[戻る] をクリックしてください...」が表示されます...
これは、共有ポイント サイトを作成するための Web パーツ内のコードです。
using (SPSite objSite = new SPSite(SPContext.Current.Site.ID))
{
objSite.AllowUnsafeUpdates = true;
using (SPWeb objWeb = objSite.OpenWeb(SPContext.Current.Web.ID))
{
objWeb.AllowUnsafeUpdates = true;
SPWeb NewWeb3 = null;
try
{
NewWeb3 = objSite.AllWebs.Add(RelativeITTURL, projectCode, SiteDescription, LocaleID, ITTSiteDefinitionTemplate, false, false);
NewWeb3.AllowUnsafeUpdates = true;
NewWeb3.Navigation.UseShared = true;
NewWeb3.BreakRoleInheritance(true);
NewWeb3.AllowUnsafeUpdates = true;
ITTSiteID = new Guid(NewWeb3.ID.ToString());
NewWeb3.Update();
NewWeb3.AllowUnsafeUpdates = false;
}
catch (Exception ex3)
{
StringBuilder Message = new StringBuilder();
Message.Append(string.Format("Error while creating the site for the 3rd time. '{0}/{1}'\n", _siteCollection, projectCode));
Message.Append(string.Format("Project Code: {0}\n", projectCode));
Message.Append(string.Format("ITT Site URL: {0}\n", FullITTSiteURL));
Message.Append(string.Format("Web Template: {0}\n", _webTemplate));
Message.Append(string.Format("Web Template To String: {0}\n", ITTSiteDefinitionTemplate.ToString()));
Message.Append(string.Format("Locale ID: {0}\n", LocaleID.ToString()));
//Message.Append(string.Format("Form digest validated: {0}\n", ValidateFormDigect.ToString()));
NFER.ErrorManagement.ErrorLog.LogErrorToEventLog(ex3, Message.ToString());
lblProvisionStatus.Text = "An error occurred while creating the site. Please close your browser and try again.";
return;
}
finally
{
//Since an error can occur
if (NewWeb3 != null)
NewWeb3.Dispose();
}
}
}
この行でエラーが発生します
CurrentSite.AllWebs.Add...
システム アカウントではサイトを正常に作成できますが、制限付きのテスト アカウントでは失敗します。面白いことに、ある時点では機能していましたが、現在は機能していません。
これは呼び出しスタックです
