I have been looking for a good solution all day, but Google evolves so fast that I can't find something working. What I want to do is that, I have a Web app that has an admin section where user need to be logged in to see the information. In this section I want to show some data from GA, like pageviews for some specific urls. Since it's not the user information that I'm showing but the google analytics'user I want to connect passing information (username/password or APIKey) but I can't find out how. All the sample I found use OAuth2 (witch, if I understand, will ask the visitor to log in using google).
What I found so far :
Maybe I'm just tired and that tomorrow it will be easy to find a solution but right now I need help!
Thanks
I did a lot of search and finally either looking up code from multiple places and then wrapping my own interface around it i came up with the following solution. Not sure if people paste their whole code here, but i guess why not save everyone else time :)
Pre-requisites, you will need to install Google.GData.Client and google.gdata.analytics package/dll.
This is the main class that does the work.
namespace Utilities.Google
{
public class Analytics
{
private readonly String ClientUserName;
private readonly String ClientPassword;
private readonly String TableID;
private AnalyticsService analyticsService;
public Analytics(string user, string password, string table)
{
this.ClientUserName = user;
this.ClientPassword = password;
this.TableID = table;
// Configure GA API.
analyticsService = new AnalyticsService("gaExportAPI_acctSample_v2.0");
// Client Login Authorization.
analyticsService.setUserCredentials(ClientUserName, ClientPassword);
}
/// <summary>
/// Get the page views for a particular page path
/// </summary>
/// <param name="pagePath"></param>
/// <param name="startDate"></param>
/// <param name="endDate"></param>
/// <param name="isPathAbsolute">make this false if the pagePath is a regular expression</param>
/// <returns></returns>
public int GetPageViewsForPagePath(string pagePath, DateTime startDate, DateTime endDate, bool isPathAbsolute = true)
{
int output = 0;
// GA Data Feed query uri.
String baseUrl = "https://www.google.com/analytics/feeds/data";
DataQuery query = new DataQuery(baseUrl);
query.Ids = TableID;
//query.Dimensions = "ga:source,ga:medium";
query.Metrics = "ga:pageviews";
//query.Segment = "gaid::-11";
var filterPrefix = isPathAbsolute ? "ga:pagepath==" : "ga:pagepath=~";
query.Filters = filterPrefix + pagePath;
//query.Sort = "-ga:visits";
//query.NumberToRetrieve = 5;
query.GAStartDate = startDate.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);
query.GAEndDate = endDate.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);
Uri url = query.Uri;
DataFeed feed = analyticsService.Query(query);
output = Int32.Parse(feed.Aggregates.Metrics[0].Value);
return output;
}
public Dictionary<string, int> PageViewCounts(string pagePathRegEx, DateTime startDate, DateTime endDate)
{
// GA Data Feed query uri.
String baseUrl = "https://www.google.com/analytics/feeds/data";
DataQuery query = new DataQuery(baseUrl);
query.Ids = TableID;
query.Dimensions = "ga:pagePath";
query.Metrics = "ga:pageviews";
//query.Segment = "gaid::-11";
var filterPrefix = "ga:pagepath=~";
query.Filters = filterPrefix + pagePathRegEx;
//query.Sort = "-ga:visits";
//query.NumberToRetrieve = 5;
query.GAStartDate = startDate.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);
query.GAEndDate = endDate.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);
Uri url = query.Uri;
DataFeed feed = analyticsService.Query(query);
var returnDictionary = new Dictionary<string, int>();
foreach (var entry in feed.Entries)
returnDictionary.Add(((DataEntry)entry).Dimensions[0].Value, Int32.Parse(((DataEntry)entry).Metrics[0].Value));
return returnDictionary;
}
}
}
And this is the interface and implementation that i use to wrap it up with.
namespace Utilities
{
public interface IPageViewCounter
{
int GetPageViewCount(string relativeUrl, DateTime startDate, DateTime endDate, bool isPathAbsolute = true);
Dictionary<string, int> PageViewCounts(string pagePathRegEx, DateTime startDate, DateTime endDate);
}
public class GooglePageViewCounter : IPageViewCounter
{
private string GoogleUserName
{
get
{
return ConfigurationManager.AppSettings["googleUserName"];
}
}
private string GooglePassword
{
get
{
return ConfigurationManager.AppSettings["googlePassword"];
}
}
private string GoogleAnalyticsTableName
{
get
{
return ConfigurationManager.AppSettings["googleAnalyticsTableName"];
}
}
private Analytics analytics;
public GooglePageViewCounter()
{
analytics = new Analytics(GoogleUserName, GooglePassword, GoogleAnalyticsTableName);
}
#region IPageViewCounter Members
public int GetPageViewCount(string relativeUrl, DateTime startDate, DateTime endDate, bool isPathAbsolute = true)
{
int output = 0;
try
{
output = analytics.GetPageViewsForPagePath(relativeUrl, startDate, endDate, isPathAbsolute);
}
catch (Exception ex)
{
Logger.Error(ex);
}
return output;
}
public Dictionary<string, int> PageViewCounts(string pagePathRegEx, DateTime startDate, DateTime endDate)
{
var input = analytics.PageViewCounts(pagePathRegEx, startDate, endDate);
var output = new Dictionary<string, int>();
foreach (var item in input)
{
if (item.Key.Contains('&'))
{
string[] key = item.Key.Split(new char[] { '?', '&' });
string newKey = key[0] + "?" + key.FirstOrDefault(k => k.StartsWith("p="));
if (output.ContainsKey(newKey))
output[newKey] += item.Value;
else
output[newKey] = item.Value;
}
else
output.Add(item.Key, item.Value);
}
return output;
}
#endregion
}
}
And now the rest is the obvious stuff - you will have to add the web.config values to your application config or webconfig and call IPageViewCounter.GetPageViewCount
