Question

我试图从iTunes Search API获取播客剧集列表。我可以拨打API并根据搜索字词取回所有播客专辑：

https://itunes.apple.com/search?media=podcast&term=nerdcast

返回以下json（裁剪）：

{
"resultCount": 20,
"results": [
    {
        "wrapperType": "track",
        "kind": "podcast",
        "collectionId": 381816509,
        "trackId": 381816509,

        "artworkUrl100": "http://a1.mzstatic.com/us/r30/Podcasts/v4/e1/95/35/e1953536-8437-834e-eac8-01147ae11c9e/mza_3422052630315608394.100x100-75.jpg",

        "trackCount": 301,
        "country": "USA",
        "currency": "USD",
        "primaryGenreName": "Society & Culture",
        "radioStationUrl": "https://itunes.apple.com/station/idra.381816509",
        "artworkUrl600": "http://a2.mzstatic.com/us/r30/Podcasts/v4/e1/95/35/e1953536-8437-834e-eac8-01147ae11c9e/mza_3422052630315608394.600x600-75.jpg",
        "genreIds": [
            "1324",
            "26"
        ],
        "genres": [
            "Society & Culture",
            "Podcasts"
        ]
    },
.....

我现在想从第一个结果中获取所有剧集。我尝试使用collectionId执行查找请求，但它只返回与上面相同的输出，而不是该集合中的所有播客。

https://itunes.apple.com/lookup?id=381816509&entity=podcast

通过阅读文档和其他一些帖子，我认为它应该如何运作，但它并没有。有人能帮帮我吗？感谢。

Answer 1

我认为您需要做的是获取该Feed网址并直接从那里获取曲目

“feedUrl”：“http://jovemnerd.com.br/categoria/nerdcast/feed/”，

我怀疑iTunes搜索API文档和实现包含未明确说明的警告。

Answer 2

对我来说，这很有效。我用这个代码： https://github.com/ijanerik/PHP-iTunes-API/blob/master/README.md

foreach($results as $item){
$url = $item->feedUrl;
}
$xml = simplexml_load_file($url) or die("feed not loading");
print_r($xml);
