为iTunes制作播客RSS源

Question

我正在使用PHP构建RSS源，并希望它在iTunes中很好地显示。

• 如何格式化RSS源以便iTunes喜欢它？
• 我应该使用哪些特殊标签？
• 将它提交到iTunes目录的最佳方式是什么（只需一次，或定期重新提交以保持“新鲜”）？
• 有哪些最佳实践，提示和技巧可以使Feed在iTunes Store中显眼？

Answer 1

RSS源的格式应与其他任何带有机箱的格式相同。 网上有数百种资源描述了如何制作这样的资料。

这里会告诉您RSS源中需要的iTunes特定标签。

请注意，Apple已经严重破坏了iTunes 9中的播客支持，所以如果它看起来不能正常工作，请不要气馁：这可能是Apple的错。

Answer 2

我已为此创建了一个小型PHP库，您可以在此处找到它。

这是一个例子：

use iTunesPodcastFeed\Channel;
use iTunesPodcastFeed\FeedGenerator;
use iTunesPodcastFeed\Item;

require __DIR__ . '/vendor/autoload.php';

// SETUP CHANNEL
$title = 'Read2Me Daily Curated Articles';
$link = 'https://read2me.online';
$author = 'NYTimes and Medium';
$email = 'hello@read2me.online';
$image = 'https://d22fip447qchhd.cloudfront.net/api/widget/static/images/default-thumbnail.png';
$explicit = false;
$categories = [
    'News',
    'Technology',
    'Culture',
    'Entrepreneurship',
    'Productivity'
];
$description = 'Daily curated articles from New York Times and Medium';
$lang = 'en';
$copyright = 'The New York Times Company and The Medium Company';
$ttl = 43200; // 12 hours in seconds

$channel = new Channel(
    $title, $link, $author, $email,
    $image, $explicit, $categories,
    $description, $lang, $copyright, $ttl
);

// SETUP EPISODE
$title = "Trump Says Disclosure of Mueller Questions in Russia Probe Is ‘Disgraceful’";
$fileUrl = 'https://s3.read2me.online/audio/www-nytimes-com-2018-05-01-us-politics-trump-mueller-russia-questions-html-7e9601.mp3';
$duration = '2:18';
$description = 'WASHINGTON — President Trump on Tuesday said it was “disgraceful” that questions the special counsel would like to ask him were publicly disclosed, and he incorrectly noted that there were no questions about collusion. The president also said collusion was a “phony” crime.';
$date = 1525177808;
$filesize = 828387;
$mime = 'audio/mpeg';

$item = new Item(
    $title, $fileUrl, $duration,
    $description, $date, $filesize, $mime
);
$item2 = clone $item; // just to give you an idea of how it works

// SETUP FEED
$feed = new FeedGenerator($channel, ...[$item, $item2]);

// OUTPUT XML
header('Content-Type: application/xml; charset=utf-8');

print $feed->getXml();
