About embedly-dotnet

embedly-dotnet is a .Net client for Embed.ly.

Available as a NuGet Package

Features

• High-performance URL matching (without regex's)
• Auto batching of url lookups
• Async downloading with configurable timeout
• Request filtering based on provider properties
• Caching of embedly responses to prevent re-requesting urls

Examples

See the sample project for complete examples.

Create an Embed.ly client

The client handles all interaction with embedly and requires a key to use. No caching will be performed by default.

var key = ConfigurationManager.AppSettings["embedly.key"];
var client = new Client(key);

Use a Cache

A cache (implementing a simple IResponseCache interface) can be passed to the Client constructor and ensures any requests to previously requested urls are served from the cache instead of being re-requested.

var key = ConfigurationManager.AppSettings["embedly.key"];
var database = ConfigurationManager.ConnectionStrings["embedly.cache"];
var cache = new MongoResponseCache(database.ConnectionString);
var client = new Client(key, cache);

Example InMemoryResponseCache, MongoResponseCache (MongoDB) and AdoResponseCache (e.g. SQL Server) implementation are included.

Check if URL supported by Embed.ly

This is used internally to ensure the only Urls sent to embedly are supported ones.

client.IsUrlSupported(url);

Retrieve Video Information

This shows a request for a video Url from YouTube.

var result = client.GetOEmbed(new Uri(@"http://www.youtube.com/watch?v=YwSZvHqf9qM"), new RequestOptions { MaxWidth = 320 });
		
// basic response information
var response = result.Response;
Console.WriteLine("Type           : {0}", response.Type);
Console.WriteLine("Version        : {0}", response.Version);

// link details
var link = result.Response.AsLink;
Console.WriteLine("Author         : {0}", link.Author);
Console.WriteLine("AuthorUrl      : {0}", link.AuthorUrl);
Console.WriteLine("CacheAge       : {0}", link.CacheAge);
Console.WriteLine("Description    : {0}", link.Description);
Console.WriteLine("Provider       : {0}", link.Provider);
Console.WriteLine("ProviderUrl    : {0}", link.ProviderUrl);
Console.WriteLine("ThumbnailHeight: {0}", link.ThumbnailHeight);
Console.WriteLine("ThumbnailUrl   : {0}", link.ThumbnailUrl);
Console.WriteLine("ThumbnailWidth : {0}", link.ThumbnailWidth);
Console.WriteLine("Title          : {0}", link.Title);
Console.WriteLine("Url            : {0}", link.Url);
Console.WriteLine();

// video specific details
var video = result.Response.AsVideo;
Console.WriteLine("Width          : {0}", video.Width);
Console.WriteLine("Height         : {0}", video.Height);
Console.WriteLine("Html           : {0}", video.Html);
Console.WriteLine();

Lookups Urls matching specific provider

A list of urls can be automatically filtered based on any property of the provider. In this case, we're only interested in getting information about YouTube videos ('urls' is IEnumerable<Uri>).

var results = client.GetOEmbeds(urls, provider => provider.Name == "youtube", new RequestOptions { MaxWidth = 320 });

Lookups Urls based on provider type

Similar to the previous example, this expands the lookup to cover all providers of videos.

var results = client.GetOEmbeds(urls, provider => provider.Type == ProviderType.Video, new RequestOptions { MaxWidth = 320 });

Limitations

The current version supports oEmbed.
