How could I get access to the Audit log for non-admin users?

I'm building a Web Part for SharePoint 2010 and I've found out that non-ad开发者_Python百科min users are getting Access Denied error message when I execute the following code (the error is thrown in the last line):

SPAuditQuery wssQuery = new SPAuditQuery(web.Site);
wssQuery.RestrictToUser(web.CurrentUser.ID);
wssQuery.AddEventRestriction(SPAuditEventType.View);
wssQuery.RestrictToList(SPContext.Current.List);

SPAuditEntryCollection auditCol;
auditCol = web.Site.Audit.GetEntries(wssQuery);

How can I let non-admin users access this log from the web part? Because I need to filter by nono-admin users, even if a non-admin user is logged in at that moment.

.NET Reflector tells me that the SPAuditEntryCollection GetEntries(SPAuditQuery query) method performs the following check before it attempt to retrieve data:

if (!this.m_Web.CurrentUser.IsSiteAdmin)
{
    throw new UnauthorizedAccessException();
}

You can consider:

1. querying the dbo.AuditData table directly (accessing SharePoint database directly is generally discouraged, but you'll read-only access, so it shouldn't cause any problems),

2. creating a custom SharePoint Web service - this should be simple, because all it needs to do is execute the GetEntries method and return the result.
