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.
下载经常失效,显示“暂不支持下载”,但是同样的视频有的时候又可以下载。用其他插件就没问题。

之前用得挺好的,但是今天出现问题了,网速很快的情况下,任何视频下载到99%直接挂了,chrome里按resume也不行,是不是哔哩哔哩出的防控呢?
多P视频只能下载第一P
您好,能提供字幕下載功能嗎?插件不支持下載字幕,bilibili開始使用cc字幕后,插件下載視頻后無字幕
太好用了,谢谢你
