Custom web service in SharePoint 2010

Question

Hi,
I have developed one custom web service and deployed in inside 14 hive Layout folder. I have to consume this custom web service in WCF REST services. This WCF REST service will be consumed in to HTML 5 and javascript application (Presentation Layer). Here
is the code for Custom web service :
[WebMethod]
public string[] GetSponsorList()
string url = "https://ptmdev.bpiper.com/";
//string strUserName = "ravikant";
string sponsorTitle = string.Empty;
string[] arrTitle;
string[] myArray;
DataTable dtSponsor = new DataTable();
string error = string.Empty;
ArrayList myArrayList = new ArrayList();
try
dtSponsor.Columns.Add(new DataColumn("sValue", typeof(string)));
dtSponsor.Columns.Add(new DataColumn("sText", typeof(string)));
using (SPSite site = new SPSite(url))
using (SPWeb web = site.OpenWeb())
//SPUserToken userToken = web.AllUsers[strUserName].UserToken;
SPWebApplication webApplication = SPContext.GetContext(web).Site.WebApplication;
SPSiteCollection siteCollections = webApplication.Sites;
int i = 0;
if(web.CurrentUser!=null)
myArrayList.Add("User:"+web.CurrentUser.LoginName);
else
myArrayList.Add("Null User..");
foreach (SPSite siteCollection in siteCollections)
if (siteCollection.RootWeb.DoesUserHavePermissions(SPBasePermissions.ViewPages))
if (siteCollection.Url.ToString().ToLower().Contains("/sponsor/"))
sponsorTitle = siteCollection.RootWeb.Title;
if (string.IsNullOrEmpty(sponsorTitle))
arrTitle = siteCollection.Url.Split('/');
sponsorTitle = arrTitle[arrTitle.Length - 1];
dtSponsor.Rows.Add(new object[] { siteCollection.Url, sponsorTitle });
i = i + 1;
siteCollection.Close();
catch (Exception ex)
error = ex.Message;
myArrayList.Add(error);
if (dtSponsor.Rows.Count == 0)
myArrayList.Add("No Data available 101");
myArrayList.Add("No Data available 102");
myArrayList.Add("No Data available 103");
for (int i = 0; i <= dtSponsor.Rows.Count - 1; i++)
for (int j = 0; j <= dtSponsor.Columns.Count - 1; j++)
myArrayList.Add(dtSponsor.Rows[i][j].ToString());
myArray = (string[])myArrayList.ToArray(typeof(string));
return myArray;
Above code will return a string array of SiteCollection URLs and Title. Th issue is siteCollection.RootWeb.DoesUserHavePermissions(SPBasePermissions.ViewPages)
logic is failed and due to this string array does not return desired result.
web object is not containing users information due to that DoesUserHavePermissions logic is
failing.
Urgent help is needed.
Thanks,
Ravi

Hi,
According to your post, my understanding is that you have issue about siteCollection.RootWeb.DoesUserHavePermissions(SPBasePermissions.ViewPages) logic when you custom web service.
You can use siteCollection.RootWeb.DoesUserHavePermissions( SPContext.Current.Web.CurrentUser, SPBasePermissions.ViewPages)
 to check whether it works.
In addition, you can use a RunWithElevatedPrivileges delegate.
For more information, you can refer to:
“Attempted to perform an unauthorized operation” and SPWeb.DoesUseHavePermissions
