Threads Trending Scraper - Lấy bài viết từ mục "Trending now" trên Threads.
|
||||
|
||||
Threads API chính thức không cung cấp endpoint cho trending topics.
|
||||
Module này sử dụng Playwright để scrape nội dung trending từ giao diện web Threads.
|
||||
|
||||
Flow:
|
||||
1. Mở trang tìm kiếm Threads (https://www.threads.net/search)
|
||||
2. Trích xuất trending topic links
|
||||
3. Truy cập từng topic để lấy danh sách bài viết
|
||||
4. Truy cập bài viết để lấy replies (nếu cần)
