Google .NET APIs - any other DataStore other than the FileDataStore?

asp.net, asp.net-mvc, c#, google-api, google-api-dotnet-client

Solution

The source for Google's FileDataStore is available here.

I've written a simple Entity Framework (version 6) implementation of IDataStore as shown below.

If you're looking to put this in a separate project, as well as EF you'll need the Google.Apis.Core nuget package installed.

public class Item
{
    [Key]
    [MaxLength(100)]
    public string Key { get; set; }

    [MaxLength(500)]
    public string Value { get; set; }
}

public class GoogleAuthContext : DbContext
{
    public DbSet<Item> Items { get; set; }
}

public class EFDataStore : IDataStore
{
    public async Task ClearAsync()
    {
        using (var context = new GoogleAuthContext())
        {
            var objectContext = ((IObjectContextAdapter)context).ObjectContext;
            await objectContext.ExecuteStoreCommandAsync("TRUNCATE TABLE [Items]");
        }
    }

    public async Task DeleteAsync<T>(string key)
    {
        if (string.IsNullOrEmpty(key))
        {
            throw new ArgumentException("Key MUST have a value");
        }

        using (var context = new GoogleAuthContext())
        {
            var generatedKey = GenerateStoredKey(key, typeof(T));
            var item = context.Items.FirstOrDefault(x => x.Key == generatedKey);
            if (item != null)
            {
                context.Items.Remove(item);
                await context.SaveChangesAsync();
            }
        }
    }

    public Task<T> GetAsync<T>(string key)
    {
        if (string.IsNullOrEmpty(key))
        {
            throw new ArgumentException("Key MUST have a value");
        }

        using (var context = new GoogleAuthContext())
        {
            var generatedKey = GenerateStoredKey(key, typeof(T));
            var item = context.Items.FirstOrDefault(x => x.Key == generatedKey);
            T value = item == null ? default(T) : JsonConvert.DeserializeObject<T>(item.Value);
            return Task.FromResult<T>(value);
        }
    }

    public async Task StoreAsync<T>(string key, T value)
    {
        if (string.IsNullOrEmpty(key))
        {
            throw new ArgumentException("Key MUST have a value");
        }

        using (var context = new GoogleAuthContext())
        {
            var generatedKey = GenerateStoredKey(key, typeof (T));
            string json = JsonConvert.SerializeObject(value);

            var item = await context.Items.SingleOrDefaultAsync(x => x.Key == generatedKey);

            if (item == null)
            {
                context.Items.Add(new Item { Key = generatedKey, Value = json});
            }
            else
            {
                item.Value = json;
            }

            await context.SaveChangesAsync();
        }
    }

    private static string GenerateStoredKey(string key, Type t)
    {
        return string.Format("{0}-{1}", t.FullName, key);
    }
}

Problem

I'm using the Google .NET API to get analytics data from google analytics. this is me code to start the authentication: ``` IAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer { ClientSecrets = new ClientSecrets { ClientId = googleApiClientId, ClientSecret = googleApiClientSecret }, Scopes = new[] { Google.Apis.Analytics.v3.AnalyticsService.Scope.AnalyticsReadonly }, DataStore = new Google.Apis.Util.Store.FileDataStore("Test_GoogleApi") }); ``` it users the FileDataStore which stores in local user profile as a file. I'm running this code inside an ASP.NET application so I can't really use that FileDataStore so what I will need is some other way to get the data. Google.Apis.Util.Store contains only the FileDataStore and an interface of IDataStore. Before I go and implement my own DataStore - are there any other DataStore objects out there available for download? Thanks
