Resolving media attributes

In order resolve media attributes you need to load providers's configuration

videos

Current video resolvers (youtube , vimeo)

// resolve all videos at once 
$videos = $grawler->videos('iframe')->resolve();

then you can access videos attributes as follow

foreach($videos as $video)
{
  $video->id; // the video provider id
  $video->title;
  $video->description;
  $video->url;
  $video->embedUrl;
  $video->images; // Collection of Image instances
  $video->author;
  $video->authorId;
  $video->duration;
  $video->provider; //video source
}

you can also resolve videos individually as follow

$videos = $grawler->videos('iframe')

foreach($videos as $video)
{
  $video->resolve();
  $video->title;
  //...
}

audio

Current video resolvers (soundcloud)

// resolve all audio at once 
$audio = $grawler->audio('.audio iframe')->resolve();

then you can access videos attributes as follow

foreach($audio as $track)
{
  $track->id; // the video provider id
  $track->title;
  $track->description;
  $track->url;
  $track->embedUrl;
  $track->images; // Collection of cover photo instances
  $track->author;
  $track->authorId;
  $track->duration;
  $track->provider; //video source
}

you can also resolve audio individually as follow

$track = $grawler->track('.audio iframe')

foreach($audio as $track)
{
  $track->resolve();
  $track->title;
  //...
}

Resolving page urls

$links = $grawler->links('.main thumb a')

foreach($links as $link)
{
  print $link
  //or
  print $link->uri
  //or
  print $link->getUri()
}

Configuration

Client Config

Set user agent

$client->agent('Googlebot/2.1')->download('http://example.com');

Recomended : http://webmasters.stackexchange.com/questions/6205/what-user-agent-should-i-set

Set request auth

$client->auth('me', '**')

you can change the auth type as follow

$client->auth('me', '**', $type = 'basic');

Set request method

$client->method('post');

Grawler config

By default the grawler tries to access those environment variables

GRAWLER_YOUTUBE_KEY

GRAWLER_VIMEO_KEY
GRAWLER_VIMEO_SECRET

GRAWLER_SOUNDCLOUD_KEY
GRAWLER_SOUNDCLOUD_SECRET

if you don't use env vars you can load configuration as follow.

$config = [
  'youtubeKey'   =>'',
  'soundcloudKey'=>''

  'vimeoKey'    => '',
  'vimeoSecret' => '',

  'soundcloudKey'    => '',
  'soundcloudSecret' => '',
];

$grawler->loadConfig($config);

Testing

$ phpunit --testsuite unit

$ phpunit --testsuite integration

NB: you should set your ptoviders key (youtube,vimeo,soundcloud...) to run integration tests
