AI 产品解读Bilibili (B站) video downloader — extracts video metadata from Bilibili pages and enables direct video file download by modifying response headers to force browser download
Users want to download Bilibili videos for offline viewing, but Bilibili does not natively offer a download button. The extension intercepts Bilibili's video CDN streams and sets Content-Disposition headers to 'attachment', triggering file downloads.
1. User installs extension and navigates to a Bilibili video/bangumi page. 2. Content script (video_bilibili_accessible.js) reads video metadata from the page's __INITIAL_STATE__ or __playinfo__. 3. Content script (video_bilibili_content.js) displays download options injected into the page UI. 4. When user clicks download, the popup/background resolves video URLs via Bilibili's player API. 5. declarativeNetRequest rules rewrite the Referer header and set Content-Disposition:attachment on bilivideo CDN requests, forcing the browser to download the video file instead of streaming it. 6. Optionally, the user can convert the downloaded video format via cv.pictureknow.com.

- 目标用户
- Chinese internet users who watch videos on Bilibili and want to download them for offline use / Users browsing Chinese e-commerce platforms (Taobao, Tmall, JD) looking for coupons
- All JS files are minified/webpack-bundled, making it difficult to trace exact application logic beyond keyword scanning
- The coupon_content.js and jd_coupon_content.js files are large React bundles whose specific UI elements cannot be easily inspected
- Cannot confirm whether the popup UI shows any paywall or upgrade prompts without rendering it
付费分析未识别到付费功能
No evidence of paid features, subscription gating, upgrade prompts, or payment platform integration found in the extension source code. Keyword matches for 'pro', 'license', and 'pay' were all false positives from React production builds, MIT license headers, CSS progress elements, and Sizzle.js internals. No Stripe, premium, membership, VIP, subscription, or upgrade keywords were found. The extension appears to be entirely free.

- The extension itself does not implement any login UI, authentication flow, or account system. It works by extracting video metadata directly from Bilibili's page state (window.__INITIAL_STATE__, window.__playinfo__) via a content script injected into bilibili.com video/bangumi pages, and calls api.bilibili.com/x/player/playurl for video URLs. No cookie manipulation, OAuth, password fields, or sign-in UI were found. However, Bilibili (the destination service) may require its own login for higher-quality streams or bangumi content, which is outside the extension's control.
不错用,虽然视频和音频要另外合成,不过有提供1080P和无损下载,实在太棒了

已经不能用了
Error: Uncaught TypeError: Cannot read properties of undefined (reading 'videoData') [object DOMException] Uncaught NotFoundError: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node. funciona bien
The extension hijacks google search results and injected results from bing. Very disrespectful behavior.
挺好用的,但是好像被禁用了,不能下载了,希望大佬能够修复一下。
