http文件服務(wù)器
原代碼地址：GitHub倉庫：JevenM
本代碼刪除了原倉庫中的一些個人用不到的功能（生成目錄樹？），另外稍微給頁面加了一點(diǎn)格式，美化了一點(diǎn)點(diǎn)。
運(yùn)行步驟：
查看幫助信息：
$ python httpServer.py -h
usage: httpServer.py [-h] [-p PORT] [--path PATH] [--bind ADDRESS]
options:
?-h, --help ? ? ? ? ? ?show this help message and exit
?-p PORT, --port PORT ?Specify alternate port [default: 8000]
?--path PATH ? ? ? ? ? Specify the folder path to share
?--bind ADDRESS, -b ADDRESS
? ? ? ? ? ? ? ? ? ? ? ?Specify alternate bind address [default: "0.0.0.0"]
打開
Terminal/CMD窗口，進(jìn)入要共享的文件目錄，注意使用?python3?運(yùn)行代碼：
python httpServer.py [port]
然后在局域網(wǎng)內(nèi)訪問：
ip:port?就可查看和上傳下載文件了。（想要讓別的設(shè)備在局域網(wǎng)內(nèi)訪問此網(wǎng)站，需要在防火墻設(shè)置入站規(guī)則，將 TCP 協(xié)議的 port 加入入站規(guī)則中）
