Get current subsite SPDocumentLibrary

Question

I have many subsite levels, and in the last one I have a pages library. I want to access it by code, the following code says the LIST does not exist.

When I debugged, the URL of SPContext.Current.Site is the sitecollection url not

/site/site1/site3

so the SpDocumentlibrary line says that list does not exist.

on the ribbon ations

var options = {              
            url: '{SiteUrl}/_layouts/xxx/MoveFiles.aspx?items=' + myItems + '&source=' + SP.ListOperation.Selection.getSelectedList()  + '&url=' + SP.ClientContext.get_current().get_web().Url ,





protected override void OnLoad(EventArgs e)
    {
        if (Request.QueryString["items"] != null && Request.QueryString["source"] != null)
        {
            string source = Request.QueryString["source"];
            string url = Request.QueryString["url"];

            string[] items = Request.QueryString["items"].ToString().Split('|');
            LabelItems.Text = "You have selected the following items to move:<br><br>";
            source = source.Substring(1, source.Length - 2).ToLower();
            Guid sourceID = new Guid(source);

            //SPUtility.GetPageUrlPath(SPContext.Current);

            string SiteUrl = SPContext.Current.Site.Url;//Get the url of current site
            using (SPSite site = new SPSite(SiteUrl))
            {
                //open the site with the url passed
                using (SPWeb oWeb = site.OpenWeb())
                {
                    SPDocumentLibrary sourceDocLib = (SPDocumentLibrary)oWeb.Lists["Site Pages"];
                    //SPDocumentLibrary sourceDocLib = (SPDocumentLibrary)SPContext.Current.Web.Lists["Site Pages"];

                    ListItems = new System.Collections.Generic.List<SPListItem>();
                    for (int i = 1; i < items.Length; i++)
                    {
                        SPListItem currentListItem = sourceDocLib.GetItemById(int.Parse(items[i]));
                        ListItems.Add(currentListItem);
                        LabelItems.Text += currentListItem.Name + "<br>";
                    }
                }
            }         
        }
    }

UPDATE

1. My sites are like this: http://servername

http://servername/TestWorkSpace

http://servername/TestWorkSpace/Wiki

So, in the wiki subsite I have a Site Pages Library. And on that context, the new ribbon button appears.

I tried using the {SPUrl} as explained below, but it returns me only this part: http://servername/TestWorkSpace

I need to be able to create a SPWeb object based on: http://servername/TestWorkSpace/Wiki

I updated the code above.!!!

For the ribbon button the /_layouts/... will end up with a site collection relative url instead of a web relative url. In your command action when you define your ribbon button you can use the {SiteUrl} tag (which is replaced with the current web URL at run time) to generate a full URL to the application page that includes the current site. See this question and answer for more details.

For the server side of things you want to use SPContext.Current.Web instead of SPContext.Current.Site.

In the API an SPWeb refers to a site and all configuration options / content associated to it and an SPSite is the general configuration / properties of the Site Collection as a whole. (SPSite.RootWeb would give you the top level site - e.g.)

I just passed the {SiteUrl} as a Query String parameter and it solved my problem.

As i'm using CustomAction -> UrlAction and i'm passing this query string parameter.
