Hello JunTingLin! I think I encountered the same problem with you. The update function fails. |

作者您好，
首先感謝您開發並分享這麼實用的專案。我在使用過程中發現，自從過年之後，原本透過靜態爬蟲requests去抓取http://isin.twse.com.tw/isin/C_public.jsp?strMode=2 上的所有股票代號資料的方法已經無法正常運作了。我推測這可能是網站加強了防爬機制的結果。
為了解決這個問題，我對fetch.py中的fetch_data函數進行了一番修正，改用Selenium進行動態爬蟲。考慮到可能有使用者會在無GUI環境下運行此專案，我有啟用了無頭模式（headless mode）。但...一旦啟用無頭模式後，就頻繁遇到連線失敗的問題。經過一番嘗試後，我發現了一個可行的解決方案：先訪問主頁面https://isin.twse.com.tw 並暫停幾秒，然後再去訪問目標URL，這樣就能順利獲取所需的資料了。
如果我的修改存在任何問題，或者有更好的解決方案，請隨時聯繫我。
