python实例32[简单的HttpServer]

发牌SO

　　
　　通常地我们要在不同平台间共享文件，samba，ftp，cifs，ntfs的设置都是有点复杂的， 我们可以使用python提供的httpserver来提供基于http方式跨平台的文件共享。
　　
　　一 命令行启动简单的httpserver
　　进入到web或要共享文件的根目录，然后执行(貌似在python32中此module不存在了)：
python -m SimpleHTTPServer 8000
然后你就可以使用http://你的IP地址:8000/来访问web页面或共享文件了。
　　
　　二  代码启动httpserver
　　simplehttpservertest.py  


import sys
import locale
import http.server
import socketserver
addr = len(sys.argv) < 2 and "localhost" or sys.argv[1]
port = len(sys.argv) < 3 and 80 or locale.atoi(sys.argv[2])
handler = http.server.SimpleHTTPRequestHandler
httpd = socketserver.TCPServer((addr, port), handler)
print ("HTTP server is at: http://%s:%d/" % (addr, port))
httpd.serve_forever()　　
　　需要进入web或要共享的目录，执行下列：
　　simplehttpservertest.py localhost 8008
　　
　　三 第三方的python库Droopy
　　且支持可以上传文件到共享服务器

　　四 支持上传的httpserver

# v1.2，changeLog：
# +: 文件日期/时间/颜色显示、多线程支持、主页跳转
# -: 解决不同浏览器下上传文件名乱码问题：仅IE，其它浏览器暂时没处理。
# -: 一些路径显示的bug，主要是 cgi.escape() 转义问题
# ?: notepad++ 下直接编译的server路径问题

"""
    简介：这是一个 python 写的轻量级的文件共享服务器（基于内置的SimpleHTTPServer模块），
    支持文件上传下载，只要你安装了python（建议版本2.6~2.7，不支持3.x），
    然后去到想要共享的目录下，执行：
        python SimpleHTTPServerWithUpload.py 1234      
    其中1234为你指定的端口号，如不写，默认为 8080
    然后访问 http://localhost:1234 即可，localhost 或者 1234 请酌情替换。

"""Simple HTTP Server With Upload.

This module builds on BaseHTTPServer by implementing the standard GET

　　五 本地的httpserver
　　在本地机器没有联网的时候，需要使用如下：来自http://coolshell.cn/articles/1480.html
　　如果你只想让这个HTTP服务器服务于本地环境，那么，你需要定制一下你的Python的程序，下面是一个示例：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

import sys import BaseHTTPServer from SimpleHTTPServer import SimpleHTTPRequestHandler HandlerClass = SimpleHTTPRequestHandler ServerClass  = BaseHTTPServer.HTTPServer Protocol     = "HTTP/1.0" if sys.argv[1:]:     port = int(sys.argv[1]) else:     port = 8000 server_address = ('127.0.0.1', port) HandlerClass.protocol_version = Protocol httpd = ServerClass(server_address, HandlerClass) sa = httpd.socket.getsockname() print "Serving HTTP on", sa[0], "port", sa[1], "..." httpd.serve_forever()
