Added a [netease] cookies_file option. When it is set, the provider reads the account cookies straight from the Netscape-format file instead of running yt-dlp --cookies-from-browser, and yt-dlp playback, batch resolve and download for music.163.com get --cookies . A new per-host cookie-file source in internal/ytdlcookies, with an Args helper, takes precedence over the browser source.

Fixes #263 (#263)

What changed

Added a [netease] cookies_file option. When it is set, the provider reads the account cookies straight from the Netscape-format file instead of running yt-dlp --cookies-from-browser, and yt-dlp playback, batch resolve and download for music.163.com get --cookies . A new per-host cookie-file source in internal/ytdlcookies, with an Args helper, takes precedence over the browser source.

Root cause: The NetEase provider and the yt-dlp cookie plumbing only accepted a browser name, so every cookie read went through yt-dlp --cookies-from-browser. That fails on Windows with the DPAPI decryption error (yt-dlp#10927), and there was no way to supply an exported cookies file.

How it was verified

  • go test ./... passes
  • go vet ./... passes
  • go vet ./... passes
  • added/updated test: external/netease/provider_test.go::TestAccountReadsCookiesFileWithoutYTDLP
  • added/updated test: internal/ytdlcookies/cookies_test.go::TestArgsPrefersCookiesFile
  • added/updated test: config/netease_test.go::TestLoadNetEase/cookies_file

Notes for reviewers

A previous attempt at this (#485, closed by its author) noted that yt-dlp rewrites its --cookies jar on exit, so with cookies_file set yt-dlp may update the user's file. This PR does not copy the file first; happy to add that if you prefer.

The full test suite and vet pass. The new tests prove three things: the provider reads cookies from the file with yt-dlp absent from PATH, the file wins over the browser source in the yt-dlp args, and the config parses the key. Not verified on Windows with a real NetEase account. The setup wizard does not offer cookies_file; the user sets it by hand. The path does not expand ~. A maintainer may want either of these, or a different API shape for the cookie source.

Summary by CodeRabbit

  • New Features
    • NetEase playback and account access can now use an exported Netscape-format cookies file when browser-cookie access is unavailable. Configure it with cookies_file; it takes precedence over browser cookies.
    • yt-dlp resolution and downloads can use configured cookies files for supported hosts.
  • Documentation
    • Added setup guidance for exporting and configuring cookies, including a reminder to use an absolute path and keep the session file private.

Walkthrough

The NetEase provider now accepts a Netscape-format cookies file. Configuration passes the file to the provider and yt-dlp resolution. Cookie-file settings take precedence over browser-cookie settings.

Changes: NetEase cookies-file support

Layer / File(s) Summary
Configure and pass the cookie file
config/config.go, config/netease_test.go, external/netease/provider.go, providers.go, config.toml.example, config/config_golden_test.go, docs/configuration.md, docs/netease.md
The NetEase configuration parses and trims cookies_file, then passes it into provider construction. Tests check the parsed value. The example and documentation describe the option and its precedence over cookies_from.
Select and pass cookie arguments
internal/ytdlcookies/*, resolve/resolve.go, player/ytdl.go, player/ytdl_cookies_test.go, external/netease/provider.go, site/index.html
Host-specific cookie arguments prefer a configured file over a browser source. Resolution and player paths use those arguments and clean up temporary file copies. The source description lists a cookies file as an authentication option. Tests cover file selection, temporary-copy cleanup, and player argument handling.
Read cookies for NetEase account requests
external/netease/provider.go, external/netease/provider_test.go
The provider reads NetEase cookies from the configured file for account requests. Without a user ID, playlist loading attempts account lookup when either a browser source or cookie file is configured. The parser skips expired cookies. Tests cover expiry handling and file-based account requests without yt-dlp.

Priority: Normal

This adds a cookies_file option for NetEase that is used for account lookup, playback, batch resolution and downloads. The earlier review concerns about stale or expired cookies and about yt-dlp overwriting the user's file are addressed in the current code. No concrete merge-blocking risk remains.

Explanation

The title clearly identifies the main change: adding a cookies_file option for the NetEase provider. The workaround context is relevant, although the truncated text and issue reference add minor noise.

Full details: Linked Issues check

Explanation

Issue [#263] requires a NetEase cookies_file alternative to cookies_from. The configuration parses and documents cookies_file, and application wiring passes it to the provider. The provider reads Netscape cookies without yt-dlp and skips expired entries. SetYTDLCookiesFileForHost and ytdlcookies.Args give the file precedence over browser cookies. The yt-dlp paths use --cookies with a private temporary copy, including playback, batch resolution, and downloads. The added tests cover configuration parsing, provider loading without yt-dlp, source precedence, and temporary-file cleanup.

Full details: Out of Scope Changes check

Explanation

The changed configuration examples, documentation, provider code, cookie-source helper, resolver, player, application wiring, and tests directly support or document issue [#263]. The private cookie copy and expired-cookie handling support safe operation of the requested feature. No unrelated change is demonstrated by the reviewed evidence.

Full details: Docstring Coverage

Explanation

Docstring coverage is 60.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 30 functions across 11 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Select cookies that apply to the account request.

If a cookies file contains two MUSIC_U entries with different paths or domains, cookieHeaderFromNetscapeFile keeps the first name and discards the second. It also ignores expiry. An earlier stale entry can therefore replace the valid account cookie, and Account can report an unsigned-in session. Filter entries for the account URL and expiry before choosing a cookie with a duplicate name. (raw.githubusercontent.com)

Thanks for this workaround for #263. We need these changes before we merge:

  1. For each yt-dlp run that ytdlcookies.Args serves, pass a private temp copy of cookies_file and remove it after exit. yt-dlp writes its cookie jar back to that path.
  2. In cookieHeaderFromNetscapeFile in external/netease/provider.go, skip expired entries before you pick a duplicate cookie name.
  3. Add a commented cookies_file line to config.toml.example and set it in config/config_golden_test.go.
  4. In docs/netease.md, move the user_id paragraph back above the new heading.

@bjarneo bjarneo added the question Further information is requested label Oct 22, 2026
yt-dlp writes its cookie jar back to the --cookies path, so passing
cookies_file directly let it overwrite the user's file. ytdlcookies.Args
now hands each yt-dlp run a private 0600 temp copy and returns a cleanup
func; every caller removes the copy after yt-dlp exits.

cookieHeaderFromNetscapeFile now skips expired entries before it keeps
the first cookie of each name, so a stale duplicate no longer hides a
valid one. Session cookies (expiry 0) are kept.

config.toml.example documents cookies_file, the golden config test sets
and expects it, and docs/netease.md has the user_id paragraph back above
the Cookies File heading.

Verified: go test ./... and go vet ./... pass.

Thanks for the review. All four points are addressed in the new commit:

  1. ytdlcookies.Args now copies cookies_file to a private temp file (0600) for each yt-dlp run and returns a cleanup func. All four call sites (probeYTDLDuration, decodeYTDLPipe, ResolveYTDLBatchPageContext, DownloadYTDLContext) remove the copy after yt-dlp exits; in decodeYTDLPipe that waits on monitorExit. The configured file is never passed to yt-dlp.
  2. cookieHeaderFromNetscapeFile skips expired entries (session cookies, expiry 0, are kept) before it picks the first cookie of each name.
  3. config.toml.example has a commented cookies_file line, and config/config_golden_test.go sets it in the [netease] section and expects it from the uncommented example.
  4. The user_id paragraph in docs/netease.md is back above ## Cookies File.
  • go test ./... passes
  • go vet ./... passes
