c# – Google .NET API – 除FileDataStore之外的任何其他DataStore?

我使用Google .NET API从Google Analytics(分析)获取分析数据。

这是我开始验证的代码:

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")
        });

它将FileDataStore用作存储在本地用户配置文件中的文件。我在ASP.NET应用程序中运行这个代码,所以我不能真正使用该FileDataStore,所以我将需要一些其他的方式来获取数据。

Google.Apis.Util.Store只包含FileDataStore和IDataStore的接口。在我去实现我自己的DataStore之前 – 有没有可以下载的其他DataStore对象?

谢谢

Google FileDataStore的来源是here

我写了一个简单的Entity Framework(版本6)实现IDataStore,如下所示。

如果您希望将其放在单独的项目中,以及EF,您将需要安装Google.Apis.Core nuget软件包。

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);
    }
}
