0722-依然出现 HTTP Error 412问题，但AI帮助下梳理了一下解决思路

[ganyz]

在linux和windows系统下都试了一下，可行
主要操作是：# 二、打补丁 A：替换 yt-dlp 的 bilibili 提取器
# 三、打补丁 B：给 bili2text 加上 Referer 请求头

============================================

零、克隆项目

============================================
git clone https://github.com/lanbinleo/bili2text.git
cd bili2text

============================================

一、装依赖

============================================

Linux & Windows 通用

uv sync
uv sync --extra whisper --extra web

============================================

二、打补丁 A：替换 yt-dlp 的 bilibili 提取器

加上 412 challenge 解答逻辑，修复 "Unable to download webpage: HTTP 412"

============================================

--- Linux ---

curl -o .venv/lib/python3.12/site-packages/yt_dlp/extractor/bilibili.py
"https://raw.githubusercontent.com/0xvd/yt-dlp-exp/fix_bilibili/yt_dlp/extractor/bilibili.py"
rm -f .venv/lib/python3.12/site-packages/yt_dlp/extractor/pycache/bilibili*.pyc

--- Windows (PowerShell) ---

Invoke-WebRequest -Uri "https://raw.githubusercontent.com/0xvd/yt-dlp-exp/fix_bilibili/yt_dlp/extractor/bilibili.py" -OutFile ".venv\Lib\site-packages\yt_dlp\extractor\bilibili.py"
Remove-Item -Force ".venv\Lib\site-packages\yt_dlp\extractor_pycache_\bilibili*.pyc" -ErrorAction SilentlyContinue

============================================

三、打补丁 B：给 bili2text 加上 Referer 请求头

修复 "Unable to download JSON metadata: HTTP 412"

============================================

--- Linux ---

python3 -c "
p = 'src/b2t/downloaders/ytdlp.py'
c = open(p).read()
if 'http_headers' not in c:
open(p, 'w').write(c.replace(
'"no_warnings": True,\n }',
'"no_warnings": True,\n'
' "http_headers": {\n'
' "Referer": "https://www.bilibili.com/\",\n'
' "User-Agent": (\n'
' "Mozilla/5.0 (X11; Linux x86_64) "\n'
' "AppleWebKit/537.36 (KHTML, like Gecko) "\n'
' "Chrome/131.0.0.0 Safari/537.36"\n'
' ),\n'
' },\n'
' }'))
print('patched')
else:
print('already patched')
"

--- Windows (PowerShell) ---

在 PowerShell 里输入：
notepad patch.py

点击是

把下面这段完整粘贴进去（注意要保持缩进）：

p = "src/b2t/downloaders/ytdlp.py"
c = open(p, encoding="utf-8").read()
if "http_headers" not in c:
open(p, "w", encoding="utf-8").write(c.replace(
'"no_warnings": True,\n }',
'"no_warnings": True,\n'
' "http_headers": {\n'
' "Referer": "https://www.bilibili.com/",\n'
' "User-Agent": (\n'
' "Mozilla/5.0 (Windows NT 10.0; Win64; x64) "\n'
' "AppleWebKit/537.36 (KHTML, like Gecko) "\n'
' "Chrome/131.0.0.0 Safari/537.36"\n'
' ),\n'
' },\n'
' }'))
print("patched")
else:
print("already patched")

然后运行

python patch.py

============================================

四、装 ffmpeg（音视频合并需要）

============================================

--- Linux ---

sudo apt install ffmpeg # Debian/Ubuntu

sudo dnf install ffmpeg # Fedora

sudo pacman -S ffmpeg # Arch

--- Windows ---

winget install ffmpeg

============================================

五、验证

============================================

确认补丁 A 生效（输出 2 才对）

grep -c "bili_challenge_result" .venv/lib/python*/site-packages/yt_dlp/extractor/bilibili.py # Linux

或

Select-String -Pattern "bili_challenge_result" .venv\Lib\site-packages\yt_dlp\extractor\bilibili.py # Windows

确认补丁 B 生效（输出 http_headers 相关行）

grep "http_headers" src/b2t/downloaders/ytdlp.py # Linux

或

Select-String -Pattern "http_headers" src\b2t\downloaders\ytdlp.py # Windows

确认 ffmpeg 可用

ffmpeg -version

============================================

六、启动

============================================
uv run bili2text ui

[lanbinleo]

好想法，我本地跑一下看看

[python-new-scm]

没问题，可行
