Month: 2025-09 | NanmiCoder/MediaCrawler Key features delivered: - Implemented Video Download Quality Parameter and CDN Redirect Handling for Bilibili downloads. Introduced a quality selector via BILI_QN to control the desired resolution, and integrated this into the BilibiliClient with updated error handling to manage CDN redirects. The change ensures downloads succeed even when lower-quality links are used and redirects occur. - Code-level enhancements documented with a dedicated commit that enables flexible quality control and robust redirect handling. Major bugs fixed: - Fixed failure when download requests were redirected to a CDN (HTTP 302) by not following redirects and only accepting an OK response. Now redirects are properly followed, improving reliability for CDN-hosted assets and lower-quality links. - Improved error handling around download requests to gracefully handle CDN redirects and non-OK responses, reducing failed downloads. Overall impact and accomplishments: - Significantly improved reliability and user experience for media downloads from Bilibili, increasing success rates across quality levels and CDN-redirect scenarios. - Enabled flexible bandwidth management and cost control for end users by supporting lower-quality, more reliable download paths without sacrificing functionality. - Demonstrated end-to-end capability to configure client behavior via a quality parameter and robust redirect logic, aligning with business goals of stability and user satisfaction. Technologies/skills demonstrated: - Client-side configuration patterns (quality parameter via BILI_QN) and integration into existing BilibiliClient. - HTTP redirect handling and robust error management in a media download workflow. - Clear mapping of business value to technical changes (reliability, flexibility, and user control).
