简单http文件服务器 （Python）

　　日常工作中，主要是通过ssh终端（putty等）远程开发，经常涉及到传输文件，因为本地系统为Win10，所以没办法利用强大的linux脚本来进行文件传输。之前用过python的SimpleHttp模块写了一个简单的文件服务器（http://www.cnblogs.com/sxhlinux/p/6694904.html），但是缺少GUI，且仍然依赖curl等相关命令。所以，就想着写一个简单的http文件服务器，满足普通的文件上传、下载文件。
        代码采用python 3.4版本，结构如下

 

代码如下

#### server.py ####

#!/usr/bin/python3
 
import sys
from http.server import BaseHTTPRequestHandler, HTTPServer, CGIHTTPRequestHandler
 
if __name__ == '__main__':
    try:
        handler = CGIHTTPRequestHandler
        handler.cgi_directories = ['/cgi-bin', '/htbin']
        port = int(sys.argv[1])
        print('port is %d'% port)
        server = HTTPServer(('', port), handler)
        print('Welcome to my website !')
        server.serve_forever()
 
    except KeyboardInterrupt:
        print ('^C received, shutting down server')
        server.socket.close()

 

#### index.html ####

<!DOCTYPE html>
<html>
<meta charset="utf-8">
<head>
    <title>File Server</title>
</head>
<body>
    <form action="/cgi-bin/download.py" method="get">
        要下载的文件: <input type="text" name="filename" />
        <input type="submit" value="download">
    </form>
 
    <form enctype="multipart/form-data" action="/cgi-bin/upload.py" method="post">
        要上传的文件: <input type="file" name="filename" />
        <input type="submit" value="upload">
    </form>
</body>
</html>

 

#### download.py ####

#!/usr/bin/python3
 
import os
import sys
import cgi
 
form = cgi.FieldStorage()
 
filename = form.getvalue('filename')
 
dir_path = "/home/sxhlinux/data/"
target_path = dir_path + str(filename)
if os.path.exists(target_path) == True:
    print ('Content-Type: application/octet-stream')
    print ('Content-Disposition: attachment; filename = "%s"' % filename)
 
    sys.stdout.flush()
    fo = open(target_path, "rb")
    sys.stdout.buffer.write(fo.read())
    fo.close()
else:
    print("""\
        Content-type: text/html\n
        <html>
        <head>
        <meta charset="utf-8">
        <title>File server</title>
        </head>
        <body>
        <h1> %s doesn't exist in the server:
        files in the server list below: </h1>""" % filename)
 
    for line in os.popen("ls -lh ~/data/"):
        name = line.strip().split(' ', 8)
        if len(name) == 9:
            print('''<form action="/cgi-bin/download.py" method="get">
                %s <input type="submit" name="filename" value="%s">
                </form>''' % (line, name[8]))
 
    print('</body> <html>')

 

 #### upload.py ####

#!/usr/bin/python3
 
import cgi, os
 
form = cgi.FieldStorage()
 
item = form['filename']
 
if item.filename:
    fn = os.path.basename(item.filename)
    open('/home/sxhlinux/data/' + fn, 'wb').write(item.file.read())
    msg = 'File ' + fn + ' upload successfully !'
else:
    msg = 'no file is uploaded '
 
print("""\
Content-type: text/html\n
<html>
<head>
<meta charset="utf-8">
<title>Hello world</title>
</head>
<body>
<h2>名称: %s</h2>
</body>
<html>
""" % (msg,))

 

将上述代码按照前面的目录结构放好，然后执行命令 nohup /usr/bin/python3 server.py 8001 >/dev/null &  启动文件服务端，监听8001端口，远程可以在浏览器中 输入 http://SERVER_ADDR:8001 来访问该文件服务器进行相关的文件上传下载操作。
 
注：附件中是整个demo的代码（download.py，upload.py两个文件中的目录路径 /home/sxhlinux/data 需要改成自己要存储文件的文件夹路径），有兴趣的小伙伴可以下载修改，刚学习python，欢迎大家多多提意见。
