[Bug]: AppleMusicClient.gettoken() fails: regex '(?=eyJh)' may no longer match Apple Music's developer token

[RudolfAnthony]

Severity

S3 - Medium (workaround exists)

Version / Commit

v2.13.0

What happened?

AppleMusicClient.gettoken() in musicdl/modules/utils/appleutils.py raises:

Exception: Token not found in index.js page

This appears to affect Apple Music playlist parsing (parseplaylist) and full-song downloads.

What did you expect?

AppleMusicClient should successfully retrieve the Apple Music developer token and continue playlist parsing and song downloads.

Steps to reproduce

1. Run:

musicdl -m AppleMusicClient
-p "https://music.apple.com/cn/playlist/example/pl.xxxx"
-i '{"AppleMusicClient":{"default_parse_cookies":"media-user-token=<valid_token>"}}'

2. The command produces no output.

3. The exception is likely suppressed by with suppress(Exception) in musicdl.py.

Logs / Screenshots

Hi @RudolfAnthony,

Thank you for reporting the issue with AppleMusicClient.gettoken(). It seems that the regular expression used to retrieve the Apple Music developer token might no longer be valid.

Here are a few troubleshooting steps you can try:

1. Check for Updates: Ensure that you are using the latest version of musicdl, as newer versions may include fixes for such issues.

2. Review Token Validity: Make sure your media-user-token is valid and hasn’t expired. You can try obtaining a new one from Apple Music and retest.

3. Check Network: Verify your network connection when executing the command, as network issues may also affect the ability to retrieve the token.

4. Inspect Logs: You could modify the code to add logging around the section before the exception occurs to gather more context on the failure.

5. Modify Regex: If you're comfortable with Python, you may delve into the code to update the regex in appleutils.py to align with any changes on Apple's end.

If the problem persists, please consider providing any additional logs or context around the issue, and I’ll be happy to assist further!

Best regards!
