Question

我正在使用Apple Music API的recent played endpoint来返回最近播放的媒体资产列表。

然后我要使用其中之一，并在MPMusicPlayerController上播放它。

            "editorialNotes": {
                "standard": "Maybe more than any other rapper in history, Lil Wayne’s output is defined by franchises. An artist should be so lucky to sustain the kind of longevity that would allow for multi-volume phases the likes of Wayne’s <i>Dedication</i>, and <i>Da Drought</i> mixtapes, let alone the series that made him into a superstar, <i>Tha Carter</i>. Though Wayne was not without projects in between, some seven years were allowed to pass between the release of the fourth and fifth installments of the lattermost. Fortunately, Wayne has rewarded his fans’ patience with 23 tracks that speak to a number of his most storied eras.<br />\n“Mixtape Weezy,” as Jay-Z famously coined, is alive and well on songs like the Swizz Beatz-produced “Uproar,” Wayne blacking out over a reinterpretation of G-Dep’s 2001 hit “Special Delivery.” The nostalgia doesn’t stop (or peak) there, as Wayne and Snoop Dogg share space over a flip of Dr. Dre’s “Xxplosive” on “Dope N*ggaz,” while Mannie Fresh revisits the Cash Money golden-era bounce of Juvenile’s “Ghetto Children” for “Start This Shit Off Right.” There are nods to the experimental Wayne of the <i>I Am Not A Human Being</i> projects (“Don’t Cry,” “Mess”) and also the rapper’s under-heralded pop wizardry (“Famous,” which features his daughter Reginae as hook singer), and even a love song built on a gospel sample, “Dope New Gospel.” In all, <i>Tha Carter V</i> is an album for anyone who’s missed Wayne—no matter which Wayne they’d missed.",
                "short": "Weezy F Baby, and the F is for finally."
            },
            "contentRating": "explicit"
        }
    },

每当我想访问当前正在播放的元数据时，都可以使用nowPlayingItem属性来获取它，该属性返回专辑中当前曲目的MPMediaItem。

此MPMediaItem的Artwork属性为null，因此我想访问专辑的插图。我可以获取albumPersistentStoreId（例如3911653000682848550），并且正在使用它通过Apple Music API请求专辑信息：

https://api.music.apple.com/v1/catalog/us/albums/3911653000682848550

但这将返回“找不到资源”错误消息。

使用搜索端点（https://api.music.apple.com/v1/catalog/us/search?term=the+carter+v&limit=2&types=artists,albums）或最近播放的原始端点，我发现其中返回的专辑ID与在albumPersistentStoreId属性中获得的专辑ID不同。如何从MPMediaItem获取正确的专辑ID？

Answer 1

您可以使用MPMediaItem的playbackstoreID-从API请求曲目信息，并从那里获取专辑封面。
