SharePoint SPWeb重命名-异常异常异常-此网页的安全验证无效

1)设置spweb.allowunsafeupdates=true
2)您可能需要使用validateForMDigest验证FormDigest

SPSecurity.RunWithElevatedPrivileges(() =>
{
    using (SPWeb thisWeb = site.OpenWeb(webUrl))
    {  
        try
        {
            thisWeb.AllowUnsafeUpdates = true;

            if (!thisWeb.ValidateFormDigest())
                throw new InvalidOperationException("Form Digest not valid");

            thisWeb.Title = newName;
            thisWeb.Update();
        }
        finally
        {
            if(thisWeb != null)
                thisWeb.AllowUnsafeUpdates = false;
        }
    }
});
