So, I'm starting to understand a bit more of WhatsApp API and all the messages that my number received are sent to my server via Webhook. The text messages are fine, but I'm struggling with the media messages.
When the user sends an image for example, Facebook's Webhook only sends me the mime_type and the sha256 of the image.
Can anyone please guide me the steps of what I need to do?
Do I need to convert it to base64, and then write the file in my server? Do I need to use a specific function? Do I need to use another programming language that's not PHP?
I'm totally lost on this one.
The way to do this, as pointed out by #CBroe is to use the media endpoints.
Assuming message is the message from the Webhook
// Get the image information, including the download link
$image_url_handle = fopen("https://graph.facebook.com/v13.0/" . $message->id);
$image_url = "";
// Read all of the data before parsing
while (!feof($image_url_handle)) {
$image_url .= fread($image_url_handle);
}
// Close the stream
fclose(image_url_handle);
// Get the url from the image information
$image_url = json_decode($image_url)->url;
// Start a request to the download URL.
$image_stream = fopen($image_url);
Note: There is no error handling or frameworks, though this should work most of the time
We are building an application that deals with images and videos and the privacy requirement is high , where users are not allowed to gain access to the images and videos at all time (privacy option) ,
therefore we went with the option of having a php api that clients request the file and the api returns a base64 encoded response that the client decode and display ,that is for image side ,as for video we are having a trouble finding the right logic .
does VideoView in android helps me achieve this ?
does the api needs to send the video in chunks instead of one large base64 ?
is base64 even right for this requirement ,noting that user should not have direct access to the file at all times .
php api function :
function viewFile($data) {
$file = file_get_contents($data['file_path']);
$mime = mime_content_type($data['file_path']);
return ['status' => 200, 'file' => ['mime' => $mime, 'base64' => base64_encode($file)]];
}
Security with base64? That does not exist. I made a text (in Portuguese) that might help you. Read.
I do not recommend using a very large base64. The server will have a lot of load, the download will be slow, etc.
The ideal is to divide it into smaller pieces. For this you can use bento4 e o ExoPlayer.
For images, I recommend using Cipher. More information for Android and More information for PHP
I made this code to encrypt images. It is already quite old, but I think I can help you enteder this issue.
https://github.com/valdeirpsr/estudo-openssl/blob/master/library/OpensslEncrypt/OpensslEncrypt.php
I try to publish a post with multiple videos and photos by using the PHP SDK. I uploaded videos and photos using batch request and got the id. Then I pass the media ids along with post data using attached_media. Things work fine for single or multiple photos. But not for a single video or multiple videos. I got this error: "Graph returned an error: (#10) Application does not have permission for this action" whenever ids of videos are included in attached_media.
Here is the code that I used:
$fb = $this->init(); try{ // Returns a Facebook\FacebookResponse object
$publishData = [ 'message' => $post['content']];
if(count($media_ids) > 0){
$publishData ['attached_media'] = [];
foreach($media_ids as $key => $media_id){
array_push($publishData['attached_media'],'{"media_fbid":"' . $media_id . '"}');
}
}
$response = $fb->post(
'/me/feed',$publishData
,
$accessToken
);
}
catch(FacebookResponseException $e){
echo 'Graph returned an error: ' . $e->getMessage();
echo $e->getTraceAsString();
exit;
}
catch(FacebookSDKException $e){
echo 'Facebook SDK returned an error: ' . $e->getMessage();
echo $e->getTraceAsString();
exit;
}
$graphNode = $response->getGraphNode();
Is there anyway to solve this. Thank you.
The truth is that you can't mix photos and videos. Facebook's API doesn't allow that. You can make:
A post containing video + text (description)
A post containing multiple photos + text
To make a video post you have to hit
POST https://graph-video.facebook.com/v10.0/<page id>/videos?file_url=<public file URL>&access_token=<your access token>&published=true&description=<text>
The file_url and description should be URL encoded.
To post multiple photos you first do the photo "uploading" and as a result you'll have ids. Those ids you set to attached_media param.
Getting photo ids:
POST https://graph.facebook.com/<page id>/photos?url=<public file URL>&access_token=<access token>&published=false
Notice the published=false. That's important. Without that you'll make a page post containing a single photo.
And finally making the actual page post:
POST https://graph.facebook.com/<page id>/feed?message=<text>&access_token=<access token>&attached_media[0]={"media_fbid":"<id>"}&attached_media[1]={"media_fbid":"<id>"}
P.S.
This approach assumes that you have your content uploaded somewhere else and you have public URLs where this content is available. If you have the raw files and you want to upload them to Facebook then you have to follow another approach.
I know its been a while but I was having the same problem and it's 2020...
The only way I was able to show the video in the timeline of a page was using the following Facebook documentation that covers uploading & posting a video to a user's timeline with the Facebook SDK for PHP.
https://developers.facebook.com/docs/php/howto/example_upload_video
It's clearly not the best approach but at least the video appears in the timeline with some title and description.
$data =
[
'title' => 'Your title',
'description' => 'Your description'
];
$response = $fb->uploadVideo($pageId, $videoUrl, $data, $token);
Note: the videoUrlmust be a relative path as the FacebookFile class uses functions like filesize.
Facebook doesn't directly allow to publish post with multiple videos and photos on the business page. However, it is possible on a personal page so as an alternate solution you can create a post on a personal page and share it on the business page.

How can I access thing like the url to a banner image, the channel title, the subscriber count, and the default logo image url from youtube google's api's for Youtube?
An example of the JSON api can be found here.
How can I access this contents using PHP?
proceed in this way:
$youtube = file_get_contents("https://www.googleapis.com/youtube/v3/channels?part=snippet,brandingSettings&id=UCyoUx3RguJRgbaMo07yc_KA&key=AIzaSyCZonTWlCv92Nd93j5CuFFcqGciLIe5rx4");
$data = json_decode($youtube,true);
echo "BANNER IMAGE URL: ".$data['items'][0]['brandingSettings']['image']['bannerImageUrl']."<br>";
echo "CHANNEL TITLE: ".$data['items'][0]['brandingSettings']['channel']['title']."<br>";
and so on....
this tools its very good to view the structure of a json and extract what you need
This simple snippet should do the trick.
$myData = json_decode(file_get_contents("https://www.googleapis.com/youtube/v3/channels?part=snippet,brandingSettings&id=UCyoUx3RguJRgbaMo07yc_KA&key=AIzaSyCZonTWlCv92Nd93j5CuFFcqGciLIe5rx4"));
var_dump($myData);
I would really recommend using cURL instead of file_get_contents() for performance reasons, however that should get you started.
Now that API v2 is gone, what would be a way to get a simple RSS feed of a channel, without v3 API? I'm open to Yahoo Pipes or any workaround that is simpler than creating an application for v3 API if the target is a feed reader. I only need an RSS feed. It was available publicly until now and it can cease any minute now (I think). So why not let access to it without an API key anymore.
At RSS Reader section https://support.google.com/youtube/answer/6098135?hl=en there is an option to export to an OPML file your subscriptions. Then, looking at the contents of the OPML you can extract the feeds, and the structure of each feed is:
https://www.youtube.com/feeds/videos.xml?channel_id=XXXX
So you could generate new feeds from this structure if you know the channel id. This kind of feeds are not getting the "https://youtube.com/devicesupport" error, so I expect they are going to keep working.
You can get the feeds like this:
https://www.youtube.com/feeds/videos.xml?channel_id=CHANNELID
https://www.youtube.com/feeds/videos.xml?user=USERNAME
https://www.youtube.com/feeds/videos.xml?playlist_id=YOUR_YOUTUBE_PLAYLIST_NUMBER
But the JSON format which used to be supported (with additional parameter &alt=JSON) is not supported anymore.
Additionally you can request for API key for public access to your YouTube videos from your developer console and get YouTube Videos, Playlists in JSON format like this:
- Get Channels:
https://www.googleapis.com/youtube/v3/channels?part=snippet%2CcontentDetails&forUsername={YOUR_USER_NAME}&key={YOUR_API_KEY}
- Get Playlists:
https://www.googleapis.com/youtube/v3/playlists?part=snippet%2CcontentDetails&channelId={YOUR_CHANNEL_ID}&key={YOUR_API_KEY}
- Get Playlist Videos:
https://www.googleapis.com/youtube/v3/playlistItems?part=snippet%2CcontentDetails%2Cstatus&playlistId={YOUR_PLAYLIST_ID}&key={YOUR_API_KEY}
More information from YouTube v3 docs.
in you tube, click on the subscriptions on the left hand pane. This will open up all your subscriptions in the center of the page. Scroll down and you'll find a Export to RSS reader button which produces an xml file of all your subscriptions . I've done this and added it to my prefered rss reader feedly.
If you inspect any Youtube channel page, inside the <head> you will find an rss meta node like this:
<link rel="alternate"
type="application/rss+xml" title="RSS"
href="https://www.youtube.com/feeds/videos.xml?channel_id=UCn8zNIfYAQNdrFRrr8oibKw">
This should provide you with the data you need.
Get the channel id by searching for the attribute data-channel-external-id in the source code of the YouTube channel page. (thanks to helq).
This code will grab all video titles and ids from the feed and dump it into an array:
$channel_id = 'XXX'; // put the channel id here
$youtube = file_get_contents('https://www.youtube.com/feeds/videos.xml?channel_id='.$channel_id);
$xml = simplexml_load_string($youtube, "SimpleXMLElement", LIBXML_NOCDATA);
$json = json_encode($xml);
$youtube = json_decode($json, true);
$yt_vids = array();
$count = 0;
foreach ($youtube['entry'] as $k => $v) {
$yt_vids[$count]['id'] = str_replace('http://www.youtube.com/watch?v=', '', $v['link']['#attributes']['href']);
$yt_vids[$count]['title'] = $v['title'];
$count++;
}
print_r($yt_vids);
I've created a small PHP script that scrapes a Youtube URL for video links, and then outputs them as an atom feed: https://gist.github.com/Skalman/801436d9693ff03bc4ce
URLs such as https://www.youtube.com/user/scishow/videos work.
Caveats:
The tool doesn't scrape dates
Playlists won't include more than 100 videos
Playlists include the "play all" link
Author is correctly set only for channels (e.g. not playlists)
Maybe Youtube will block you if you use this too much (but hopefully the limits are high enough)
Likely several more...
There also exist RSS-Bridge witch can extract RSS feeds from a lot of services like Twitter, Google+, Flickr, Youtube, Identi.ca, etc.
source: https://github.com/sebsauvage/rss-bridge
demo server: https://bridge.suumitsu.eu/
try using this URL:
https://www.youtube.com/feeds/videos.xml?user=USERNAME
Works fine for me.
From My Blog Post: http://tcodesblog.blogspot.com/search/label/howtofindyouryoutubechannelfeed
HOW TO FIND YOUR YOUTUBE CHANNEL FEED
In the old days, it was easy (2009) but now a days it is much harder to find it (2012-present). Here is a quick way to find your new feed from your YouTube Channel. Remember to follow the list correctly!
First find your channel id: You can do this by going to your YouTube Channel in the Dashboard
Copy the channel id: Your channel id can be found when visiting your YouTube Channel from within the Dashboard
Copy your channel id: Copy your channel id and replace channelidgoeshere below with your channel id: https://www.youtube.com/feeds/videos.xml?channel_id=channelidgoeshere
Copy your entire YouTube Channel Feed and create a simplified feed: You can do this by creating a shorter feed link in FeedBurner at http://www.feedburner.com/ (Requires a Google account. Free to use.), which is also part of Google. Create a new feed (select I'm A Podcaster! to see your videos appear in the feed and to make your feed compatible with other feed readers such as: Digg Reader, Apple iPhone Apple News App, Apple iPhone Podcasts App, Feedly, etc.) -OR- edit an existing one by copying your entire YouTube Channel Feed and then click Save Feed Details as normal
Your YouTube Channel Feed now works and your videos can be seen in a feed file directly on your FeedBurner feed. Mine is at YouTube as a feed at https://www.youtube.com/feeds/videos.xml?channel_id=UCvFR6YxwnYfLt_QqRFk_r3g & at FeedBurner as http://feeds.feedburner.com/youtube/warrenwoodhouse with my videos that appear only as text format, as an example, since I need to update mine to show my videos. You can change different settings in FeedBurner and do other things so it's worth a try since it's free and easy to use. I highly recommend using FeedBurner or another feed creation service, however, FeedBurner is your best bet since it also includes cross-feed subscription service mechanism (USM - Universal Subscription Mechanism), which means your feed can be read from any compatible device such as a computer, mobile phone (with the correct app installed), via an older web browser (such as Internet Explorer which supports Web Slices & RSS/Atom/XML Feeds).
Your feed can also be opened up in Apple iPhone Apple News App & Apple iPhone Podcasts App on your Apple iPhone, Apple iPod Touch and Apple iPad if you've set the settings correctly to USM (Universal Subscription Mechanism). Once this is in effect, your feed can be viewed through different services and devices.
Your feed on FeedBurner allows you to create an Email Subscription, Headline Animator (which shows you how a link to the latest post) along with how many subscribers, Chiclets and other cool stuff.
I hope this answer proves useful and if you want to see some more cool awesome coding practices by me, please feel free to check out my T-Codes website at http://warrenwoodhouse.webs.com/codes for lots more stuff.
I have created an example Yahoo Pipes here.
http://pipes.yahoo.com/pipes/pipe.info?_id=6eeff0110a81f2ab94e8472620770b11
You can run this pipe by pressing "Run Pipe" without API Key filled. But you must provide your own API Key and channel id (which can be obtained via channels API) when cloned. Wanted to automate fetching channelId by YouTube username but not easy to pipe.
I've made a batch script that creates an RSS feed of your new subscription videos. You don't need an API key. The script uses 2 external tools: YouTube-DL and Xidel.
Anyway, read the following thread, and go to post 98 to download the script:
http://code.google.com/p/gdata-issues/issues/detail?id=3946#c98
I hope someone codes this to php, python, javascript, powershell or bash.
I think there are some changes in youtube response so i make some changes to get channel id from rss feed using Curl.
$channel_id = 'XXXXXXXX'; // put the channel id here
//using curl
$url = 'https://www.youtube.com/feeds/videos.xml?channel_id='.$channel_id.'&orderby=published';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
//curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
$response = curl_exec($ch);
curl_close($ch);
$response=simplexml_load_string($response);
$json = json_encode($response);
$youtube= json_decode($json, true);
$count = 0;
if(isset($youtube['entry']['0']) && $youtube['entry']['0']!=array())
{
foreach ($youtube['entry'] as $k => $v) {
$yt_vids[$count]['id'] = str_replace('http://www.youtube.com/watch?v=', '', $v['link']['#attributes']['href']);
$yt_vids[$count]['title'] = $v['title'];
$count++;
}
}
else
{
$yt_vids[$count]['id']=str_replace('http://www.youtube.com/watch?v=', '', $youtube['entry']['link']['#attributes']['href']);
$yt_vids[$count]['title']=$youtube['title'];
}
echo "<pre>";
print_r($yt_vids);
I used the below code to integrate Youtube Feed with wordpress custom field "ACF plugin" & FancyBox
<?php
$channel_id = get_field('youtube_chanel_id'); //ACF text field
if ($channel_id){ // if channel_id not empty -- START
$youtube = file_get_contents('https://www.youtube.com/feeds/videos.xml?channel_id='.$channel_id);
$xml = simplexml_load_string($youtube, "SimpleXMLElement", LIBXML_NOCDATA);
$json = json_encode($xml);
$youtube = json_decode($json, true);
echo'<div class="col-md-12 youtube-videos-feed">';
foreach ($youtube['entry'] as $k => $v) {
$id = str_replace(array("yt:video:"), "", $v['id']); // Remove "yt:video:" from ID value
//$date = $v['updated']; // video updated date (disabled for now)
$title = $v['title']; // video title
echo '<a class="with-video" href="https://www.youtube.com/watch?v=',$id,'&autoplay=1&rel=0&controls=0&showinfo=0&modestbranding=0" data-fancybox="videos" data-caption="',$title,'" title="',$title,'" >
<div class="col-md-3 main-image post-image img-fancy">
<img src="https://img.youtube.com/vi/',$id,'/0.jpg" alt="',$title,'" >
</div>
</a>';
}
echo'</div>';
} // if channel_id not empty -- END
?>
I found a Chrome extension named Youtube RSS-ify that injects an RSS icon on video, channel and navigation pages. It was just what I was looking for.
Icons look like this:
I would suggest using an excellent rss parser. Many of them are available, but you can try http://simplepie.org/, one of the best I used for my personal projects.
Its pretty well documented with some examples.
Usage example
Note:Used YouTube channel college humor, you can get it from the channel page itself
<?php
include_once('../autoloader.php');
// Parse it
$feed = new SimplePie();
$feed->set_feed_url('https://www.youtube.com/feeds/videos.xml?channel_id=UCPDXXXJj9nax0fr0Wfc048g');
$feed->enable_cache(false);
$feed->init();
$items = $feed->get_items();
foreach ($items as $item)
{
echo $item->get_title() . "\n";
}
var_dump($feed->get_item_quantity());
Easiest way to get the channel id:
Open Subscription Manager (left panel, down below subscriptions) and click on the desired user.
The url will be in the form:
https://www.youtube.com/channel/XXXXXXXXXXXXXXXXX
So the feed url should be:
https://www.youtube.com/feeds/videos.xml?channel_id=XXXXXXXXXXXXXXXXX
Note: Better use channel ids rather than user names because user names may change.
