Python 刷瀏覽次數

---

說明

• 建議適當的調整執行次數與間隔時間，避免影響網站正常運作。
• 怕送太多 request 會被鎖 IP 的話，可以在 Google Colab 運行。

環境設定

• 請先安裝 Python 環境，並在終端機貼上以下指令下載所需模組。
• 進度條是為了在運行時更直觀地看到進度，移除並不會影響功能。

pip install requests tqdm

參數調整

請在 config 自行調整以下參數，總共會送出 ('rounds' × 'requests') 次請求。

1. 網　　　　址 ('url': "https://example.com")
2. 總共進行幾輪 ('rounds': 5)
3. 每輪請求數量 ('requests': 20)
4. 執 行 緒 數 量 ('workers': 10)
5. 每次請求間隔 ('delay': (1.0, 2.0))
6. 每輪請求間隔 ('DELAY': (5.0, 8.0))
