YouTube Studio 内容管理器「导出当前视图 → 逗号分隔值 (.csv)」下载脚本
|
||
（拦截响应 + 解码 zip + 自动保存到下载目录 + 重名去重）。
|
||
|
||
机制（已实证）：前端点击导出后向后端
|
||
POST https://studio.youtube.com/youtubei/v1/yta_web/csv_export?alt=json
|
||
后端把打好的 zip 以 base64 内联在响应 `zippedData` 字段里（开头 `UEsDBBQ` 即 ZIP 文件头 `PK`）。
|
||
本脚本拦截该响应，base64 解码后按 `<维度标签> <起始日>_<结束日> <账号名>.zip` 写盘，
|
||
重名自动加 ` (n)` 后缀，n 从 1 起。
|
||
|
||
登录态：脚本不负责登录，必须复用已登录 YouTube Studio 的浏览器会话，二选一：
|
||
- --user-data-dir + --channel chrome|msedge ：用已登录的用户数据目录启动（需先关闭该浏览器）
|
||
- --connect http://localhost:9222 ：附加到已在调试端口运行的浏览器
|
||
|
||
用法：
|
||
python youtube_export_download.py --selftest
|
||
python youtube_export_download.py --url "<explore URL>" --channel chrome --user-data-dir "C:\Users\<you>\AppData\Local\Google\Chrome\User Data"
|
||
python youtube_export_download.py --url "<explore URL>" --connect http://localhost:9222
