Manage Youtube videos from Sitecore

This is a series of 3 articles where I will show how you control Facebook, Twitter and Youtube feeds from Sitecore and display it on your web page.
 
In last 2 post, I showed how to manage Facebook feeds using Facebook graph API and Twitter Tweets by using its API.

In this post, we will check how to access and control Youtube video feeds from Sitecore. 

Youtube videos from Sitecore
Youtube videos from Sitecore


For this you need API keys from Google for using Youtube API. 

Implementation

Create Sitecore template having fields like

Sitecore fields for Youtube video feeds
Sitecore fields for Youtube video feeds

Code


Install Nuget package named “Google.Apis.YouTube.V3″ to your HELIX based feature project.

First we need to create Template mapping class for these Youtube fields as

namespace Sitecore.Feature.Social
{
    using Sitecore.Data;

    public struct Templates
    {
        public struct SocialFeedsManager
        {
            public static ID ID = new ID("{B1959961-A315-468D-8D03-CA50CB790C86}");
            public static ID ContentItemID = new ID("{EC8578D8-4C0F-413E-83F2-C9BA5B249E85}");


            public struct Fields
            {
            
                public static readonly ID YoutubeAPIKey = new ID("{D2B9B6B6-2A4C-4E7F-B63E-D9D119E599AA}");
                public static readonly ID YoutubeChannelId = new ID("{AEB5A02B-9CC8-4A30-92D6-63BA90F10C2B}");
                public static readonly ID YoutubeQueryPart = new ID("{BB545EE0-FFD7-4372-8D2B-AF36470A435C}");
                public static readonly ID YoutubePlatformName = new ID("{34465AAC-CB7A-4B39-96A5-2EB029C288D9}");
                public static readonly ID YoutubeFrom = new ID("{C1BE81E3-62E9-49A0-A805-F9A7A1B1B08D}");
                public static readonly ID YoutubeMaxFeedsInAll = new ID("{FAB9C465-C484-4928-8A89-C7191ADBCE61}");
                public static readonly ID YoutubeMaxFeeds = new ID("{E99D9E1D-D930-4244-B7A0-7C0E3923C44A}");
                public static readonly ID YoutubeIsActive = new ID("{D2508648-EB83-40A7-86F2-845EFA86A6F9}");            }
        }


    }
}

Create Model classes to holds values of Sitecore item fields values and JSON data return by Youtube for video feeds as
·         ChannelName – Enum for different social channel
·         YoutubeFeeds – Get video feeds from Youtube
·         SocialMediaFeed – Class to hold single video feed data from Youtube JSON data

using Google.Apis.Services;

namespace Sitecore.Feature.Social.Models
{
    public class YoutubeFeeds
    {
        public List<SocialMediaFeed> GetYoutubeVideos(string apiKey, string queryPart, string channelId, string platformName, string from, int maxResult = 2)
        {
            YouTubeService yt = new YouTubeService(new BaseClientService.Initializer() { ApiKey = apiKey });

            var searchListRequest = yt.Search.List(queryPart);
            searchListRequest.MaxResults = maxResult;
            searchListRequest.Order = SearchResource.ListRequest.OrderEnum.Date;
            searchListRequest.ChannelId = channelId;
            var searchListResult = searchListRequest.Execute();

            var lstYoutubeFeeds = searchListResult.Items.Select(x => new SocialMediaFeed
            {
                FeedID = x.Id.VideoId.ToString(),
                PlatformName = platformName,
                Title = x.Snippet.Title,
                Description = x.Snippet.Description,
                ImageURL = (x.Snippet.Thumbnails.Medium ?? x.Snippet.Thumbnails.High ?? x.Snippet.Thumbnails.Standard ?? x.Snippet.Thumbnails.Default__).Url,
                FeedURL = "https://www.youtube.com/watch?v=" + x.Id.VideoId.ToString(),
                From = from,
                Timestamp = x.Snippet.PublishedAt.Value
            }).ToList();

            return lstYoutubeFeeds;
        }
    }
}

Below is Controller code for fetching video feeds from Youtube model class and then as per settings in Sitecore item, return JSONResult of Youtube Feeds which finally received by AJAX request to show it on page.

namespace Sitecore.Feature.Social.Controllers
{
    using Newtonsoft.Json;
    using Sitecore.Data.Items;
    using Sitecore.Feature.Social.Models;
    using Sitecore.Foundation.SitecoreExtensions.Extensions;

    using System.Security.Cryptography;
    using System.Text;
    using System.Web.Mvc;
    using System.Web.Script.Serialization;
    using static Sitecore.Feature.Social.Templates;

    public class SocialController : Controller
    {
        private List<SocialMediaFeed> lstSocialFeeds = null;

        public ActionResult GetSocialFeeds(string channelName, string token)
        {
            string result = "Error - ";

            if (string.IsNullOrEmpty(channelName) || string.IsNullOrEmpty(token) || !token.Equals("accesstoken"))
            {
                result += "Unauthorized request!!!";
            }

            channelName = channelName ?? "all";
            result = CollectSocialFeeds(channelName, result);

            if (lstSocialFeeds != null && lstSocialFeeds.Count > 0)
            {
                return Json(new { success = true, responseResult = lstSocialFeeds }, JsonRequestBehavior.AllowGet);
            }
            else
            {
                return Json(new { success = false, responseResult = result }, JsonRequestBehavior.AllowGet);
            }

        }
        /// <summary>
        /// Collect all feeds in list
        /// </summary>
        /// <param name="channelName"></param>
        /// <param name="result"></param>
        /// <returns></returns>
        private string CollectSocialFeeds(string channelName, string result)
        {
            try
            {
                SocialFeedsManagerModel _SocialFeedsManagerModel = new SocialFeedsManagerModel();

                Item dataSourceItem = null;

                if (RenderingContext.CurrentOrNull != null)
                {
                    var dataSourceId = RenderingContext.CurrentOrNull.Rendering.DataSource;
                    dataSourceItem = Sitecore.Context.Database.GetItem(dataSourceId);
                }

                if (!dataSourceItem?.IsDerived(Templates.SocialFeedsManager.ID) ?? true)
                {
                    dataSourceItem = Context.Database.GetItem(SocialFeedsManager.ContentItemID);
                }

                lstSocialFeeds = new List<SocialMediaFeed>();

                switch (channelName.ToLower())
                {                    
                    case "youtube":
                        {
                            _SocialFeedsManagerModel.InitializeData(dataSourceItem, ChannelName.Youtube);

                            if (_SocialFeedsManagerModel.YoutubeIsActive)
                            {
                                YoutubeFeeds youtube = new YoutubeFeeds();
                                lstSocialFeeds = youtube.GetYoutubeVideos(_SocialFeedsManagerModel.YoutubeAPIKey, _SocialFeedsManagerModel.YoutubeQueryPart
                                    , _SocialFeedsManagerModel.YoutubeChannelId, _SocialFeedsManagerModel.YoutubePlatformName, _SocialFeedsManagerModel.YoutubeFrom,
                                    _SocialFeedsManagerModel.YoutubeMaxFeeds);
                            }
                            else
                            {
                                result += " Youtube feeds are disabled.";
                            }
                            break;
                        }       
                    default:
                        {
                            result += " Invalid Social Media.";
                            lstSocialFeeds = null;
                            break;
                        }
                }
            }
            catch (Exception ex)
            {
                result += " Occurred." + ex.Message;
                lstSocialFeeds = null;
                string str = ex.Message;
            }

            return result;
        }
    }
}

Write AJAX script and view in HTML to load the feeds 

@model Sitecore.Feature.Social.Models.JSONOutput

<div id="SocialFeedsDiv">


    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

    <script>


        $(document).ready(function () {
            var b = null;
            $("#all").click(function () {
                loadfeeds("All")
            });

            $("#Facebook").click(function () {
                loadfeeds("Facebook")
            });

            $("#Twitter").click(function () {
                loadfeeds("Twitter")
            });

            $("#Youtube").click(function () {
                loadfeeds("Youtube")
            });

            $("#Instagram").click(function () {
                loadfeeds("Instagram")
            });


            function loadfeeds(channelName) {
                $.get("/api/sitecore/social/GetSocialFeeds?channelName=" + channelName + "&token=accesstoken", function (data, status) {
                    var index = 1;
                    $("#feedlist").html("");
                    $.each(data.responseResult, function (i, field) {
                        var imageurl = "";
                        if (field.ImageURL !="" || field.ImageURL != null) {
                            imageurl = "ImageURL : <a href='" + field.FeedURL + "' ><img src='" + field.ImageURL + "' alt='" + field.Title + "' /> </a> <br>";
                        }
                        $("#feedlist").append(
                            "<li>Sr No :" + index + "<br>" +
                            "FeedID :" + field.FeedID + "<br>" +
                            "PlatformName :" + field.PlatformName + "<br>" +
                            "Title :" + field.Title + "<br>" +
                            "Description :" + field.Description + "<br>" + imageurl
                            +
                            "FeedURL :" + field.FeedURL + "<br>" +
                            "Timestamp :" + field.Timestamp + "<br>" +
                            "From :" + field.From + "<br><br><br>" + "</li>"
                        );
                        index++;
                    });
                });
            }
        });

    </script>

     <br />
    <a href="javascript:void(0)" id="all">All</a><br />
    <a href="javascript:void(0)" id="Facebook">Facebook</a><br />
    <a href="javascript:void(0)" id="Twitter">Twitter</a><br />
    <a href="javascript:void(0)" id="Youtube">Youtube</a><br />
    <a href="javascript:void(0)" id="Instagram">Instagram</a><br />

    <div id="feed">

    </div>

    <br />
    <br />

    <div id="HTMLfeed">
        <ul id="feedlist"></ul>


    </div>

</div>

We can access this action method from URL AJAX as

This will return JSON result which include individual feeds
{
    "success": true,
    "responseResult": [
        {
            "FeedID": "111111111_2222222",
            "PlatformName": "Youtube",
            "Title": "Title of video",
            "Description": " We all love free things. If you apply same concept on study, its great for professional life as well as for future",
            "ImageURL": "https://i.ztimg.com/vi/111111/default.jpg",
            "FeedURL": "https://www.youtube.com/watch?v=111111",
            "Timestamp": "/Date(1530689661000)/",
            "From": " Bill Gates"
        }
    ]
}

Once we have JSON, we can show it in page in any desired HTML format.
That’s it.
