YouTube Studio 内容管理器「导出当前视图 → 逗号分隔值 (.csv)」下载流程 —— 拦截/解码/自动保存/重名去重 参考实现。
|
||||
|
||||
## 已实证的下载生成机制(2026-08-21 抓包确认)
|
||||
|
||||
1. 前端点击「导出当前视图 → 逗号分隔值 (.csv)」后,向后端发起:
|
||||
POST https://studio.youtube.com/youtubei/v1/yta_web/csv_export?alt=json
|
||||
请求体 `exportQuery` 内含 joinRequest 各节点(表格数据/图表数据/总计),以及
|
||||
日期范围 `dateIdRange.inclusiveStart` / `dateIdRange.exclusiveEnd`(都是 YYYYMMDD)。
|
||||
|
||||
2. 后端**不在服务器上生成一个可下载的 URL**,而是直接把打好的 zip 以
|
||||
**base64 字符串**内联在响应里:
|
||||
{ "responseContext": {...}, "zippedData": "<base64>" }
|
||||
实测 `zippedData` 以 `UEsDBBQ...` 开头(即 `PK\\x03\\x04`,ZIP 魔数),
|
||||
base64 解码后得到 zip,内含 `表格数据.csv`、`图表数据.csv`、`总计.csv`。
|
||||
|
||||
3. 前端把 `zippedData` base64 解码 → Blob → 触发浏览器下载。
|
||||
由于没有出现指向下载文件的 GET/跳转,判定为「客户端 Blob 下载」而非服务端重定向。
|
||||
|
||||
4. 浏览器自身已自动保存到本机默认下载目录(本机为 `D:\\Downloads`),无需"另存为"确认;
|
||||
且 Chromium 对重名文件会自动追加 ` (1)`、` (2)` …后缀。
|
||||
|
||||
## 结论:可以跨越下载流程
|
||||
- 在响应层拦截 `csv_export`,拿到 `zippedData`,自行 base64 解码并写盘,
|
||||
即可完全掌控「保存目录 + 文件名 + 重名去重」,不依赖浏览器的下载管理器和弹窗。
|
||||
- 或者只用 Chromium 的下载偏好(auto-download + 内置去重)让它自动落盘。
|
||||
|
||||
## 文件名约定(与实测 D:\\Downloads 中产物一致)
|
||||
<维度标签> <inclusiveStart>_<exclusiveEnd> <账号名>.zip
|
||||
例:内容 2026-07-23_2026-08-20 WL Media.zip
|
||||
- 维度标签:VIDEO -> 内容;USER -> 频道(生产中建议从页面"维度"按钮文本读取)
|
||||
- 日期格式 YYYY-MM-DD:inclusiveStart 与 exclusiveEnd 各取 YYYYMMDD 转 YYYY-MM-DD
|
||||
- 账号名:右上角账号按钮文本

||||

自测(无需 Playwright): python youtube_export_interceptor.py --selftest

实际运行(需 Playwright;必须复用已登录 YouTube Studio 的浏览器会话,否则跳登录页):

方式 A(用已登录的用户数据目录启动,需先关闭 Chrome/Edge):
|
||||
python youtube_export_interceptor.py --url "<explore URL>" --channel chrome ^
|
||||
--user-data-dir "%LOCALAPPDATA%\Google\Chrome\User Data"
|
||||
方式 B(附加到已在调试端口运行的浏览器,无需关闭):
|
||||
python youtube_export_interceptor.py --url "<explore URL>" --connect http://localhost:9222
|
||||
# 先启动: chrome.exe --remote-debugging-port=9222 或 msedge.exe --remote-debugging-port=9222
