Question

我需要创建一个函数来检查字符串是否是Spotify URL。我做了一个简单的if语句来检查字符串是否包含Spotify URL的一部分，它可以工作，但它是废话。有人可以用Regex或其他东西向我展示更好的方法。

if ( input.indexOf('spotify:') > -1  || input.indexOf('spotify.com')  > -1) {
    console.log('url');
}

Spotify网址有以下三种形式：

https://play.spotify.com/user/spotifydiscover/playlist/0vL3R9wDeAwmXTTuRATa14
https://open.spotify.com/track/1TZ3z6TBztuY0TLUlJZ8R7
spotify:track:1TZ3z6TBztuY0TLUlJZ8R7

Answer 1

/^(spotify:|https://[a-z]+\.spotify\.com/)/

正确的JS转义，因为那里有很多斜杠：

var url = 'https://open.spotify.com/track/1TZ3z6TBztuY0TLUlJZ8R7';
console.log(/^(spotify:|https:\/\/[a-z]+\.spotify\.com\/)/.test(url));
// Outputs 'true'

Answer 2

匹配

var input = 'https://play.spotify.com/user/spotifydiscover/playlist/0vL3R9wDeAwmXTTuRATa14';
if(/\.spotify\.com/.test(input))
{
     // contains spotify
}

Answer 3

要测试网址是以open开头，还是play使用：

> var url = 'https://play.spotify.com/user/spotifydiscover/playlist/0vL3R9wDeAwmXTTuRATa14';
> var re = /((open|play)\.spotify\.com\/)/;
> console.log(re.test(url));
< true

使用match()您可以检索网址的格式。

> console.log(url.match(re));
< ["play.spotify.com/", "play.spotify.com/", "play"]

或者：

> console.log(url.match(re)[2]);
< "play"

Answer 4

如果有人想验证Spotify字符串，获取ID以及它是曲目还是专辑，请使用以下表达式：

const str = "https://open.spotify.com/album/0BwWUstDMUbgq2NYONRqlu?si=5qGtCb3_Qh2SburnU09NtQ";
const regEx = /^(?:spotify:|(?:https?:\/\/(?:open|play)\.spotify\.com\/))(?:embed)?\/?(album|track)(?::|\/)((?:[0-9a-zA-Z]){22})/;
const match = str.match(regEx);
if(match){
    const albumOrTrack = match[1]
    const spotifyID = match[2]
    //albumOrTrack: album
    //spotifyID: 0BwWUstDMUbgq2NYONRqlu
}

这将匹配Spotify链接，来自嵌入代码的Spotify链接以及Spotify URI。有关正则表达式工作原理的说明，请将其粘贴到https://www.regex101.com
