fix: enhance HTTP headers and retry logic to handle 403 errors from sumo.or.jp#92
Merged
Conversation
- Update User-Agent to Chrome 131 (current stable) with full version string - Add realistic browser headers: Accept-Encoding, Connection, Cache-Control, DNT, Pragma, and all Sec-CH-UA/Sec-Fetch headers - Implement exponential backoff (2s, 4s, 8s) with random jitter (0-1s) - Increase retry attempts from 3 to 4 - Add random module import These changes improve the likelihood of successful requests to sumo.or.jp by mimicking a real browser more accurately and implementing better retry behavior when facing rate limiting or bot detection. Fixes: #26353343821 (workflow run) Co-authored-by: dai <12391+dai@users.noreply.github.com>

The data update workflow started failing with
HTTP 403 Forbiddenwhen fetching from sumo.or.jp, likely due to strengthened bot detection. The incomplete User-Agent and missing modern browser headers triggered anti-scraping measures.Changes
HTTP headers now mimic Chrome 131
Accept-Encoding,Connection,Cache-Control,DNT,PragmaSec-CH-UA*,Sec-Fetch-*(18 headers total)Retry logic improvements
No guarantees against future bot detection changes, but requests now closely match real browser traffic patterns.
