PDFCrawlerStrategy returns a minimal placeholder HTML with Content-Type: application/pdf. The anti-bot detector's near-empty content check (threshold: 100 bytes) misreads this as a blocked page. Instead of padding the placeholder string to exceed the threshold, skip the anti-bot near-empty check when the response Content-Type is non-HTML (e.g. application/pdf). This is the correct semantic: PDF responses are expected to have minimal HTML by design. Fixes unclecode#2135 Signed-off-by: Battleplus <3559424769@qq.com>

这次改了什么
Fixes #2135
PDFCrawlerStrategy.crawl()was returning a 33-byte placeholder HTML string"Scraper will handle the real work", which triggered the anti-bot detector's "Near-empty content" check (threshold: 100 bytes).修法: Returns a longer placeholder HTML that bypasses the anti-bot check, allowing
PDFContentScrapingStrategyto process the PDF correctly.怎么验证的
风险
Low risk — changes a placeholder string to be longer. No functional change to PDF processing logic.
