简单http文件服务器

时间：2021-08-10 07:22:51
　　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
简单http文件服务器
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。
