Question

我需要在React Native中访问流的ICY元数据（即歌曲标题，歌手）。使用axios.head返回icy-metaint: "16000"，这意味着数据存在。如何获取流的元数据？

我是否使用类似WebSockets的方式来检索元数据？

以下代码：

  function icyMetadata() {
    const options = {
      method: 'GET',
      mode: 'cors',
      headers: {
        "Icy-MetaData": "1",
        "Access-Control-Expose-Headers": "Access-Token, Uid"
      }
    }
    axios.head('http://ais-sa1.streamon.fm/7261_64k.mp3', options)
    .then(res => console.log(res.headers))
    .catch(err => console.log(err))
  }

返回：

access-control-allow-credentials: "true"
access-control-allow-headers: "ETag, If-None-Match"
access-control-allow-origin: "*"
access-control-expose-headers: "ETag, If-None-Match"
cache-control: "no-cache"
connection: "close"
content-type: "audio/mpeg"

icy-br: "48"
icy-description: "Unspecified description"
icy-genre: "various"
icy-metaint: "16000"
icy-name: "105.9 Shine FM"
icy-pub: "1"
icy-url: ""
