本篇 ShengYu 介紹 SimpleHTTPServerWithUpload 上傳檔案功能，之前在這篇介紹怎麼使用 Python SimpleHTTPServer 快速建立簡單網頁伺服器 http web sever，這篇是網頁伺服器加上檔案上傳的功能。
https://gist.github.com/UniIsland/3346170
但是這個版本在上傳中文檔案時結果頁面會顯示亂碼，但資料夾中上傳的中文檔案名稱是正常。原因是因為它網頁編碼問題，所以我改了一版加上 utf-8 在結果頁面就可以正常顯示中文，並加上一些空白檔案名稱的錯誤處理，以及上傳時如果檔名是空的話會顯示提示視窗。
缺點是不支援多檔上傳，這樣就不方便，有點可惜。
以下是我修改的版本，1

加上 utf-8 的方法也很簡單，就是在 head 之前加上 <meta charset="utf-8">，如下所示，1

<html lang="en">
<head>
<meta charset="utf-8">

<title>Hello</title>
<body>
</body>
</html>
uploadserver
另外一個版本是使用 uploadserver（pypi 專頁連結），這個版本的優點是一次可以上傳多個檔案，跟支援 curl 指令上傳。
安裝的指令如下，1
python3 -m pip install --user uploadserver
要使用的話就這樣輸入指令，1
python3 -m uploadserver
然後要上傳的話要到 http://ip:8000/upload 頁面再選擇檔案上傳。
以上就是 Python SimpleHTTPServerWithUpload 上傳檔案功能的介紹，
