Python小脚本程序

本文旨在搜集最简单最原子性的代码块，简单清晰容易阅读，然后由用户自己组合。Python代码排版请自行修改。

这里是索引目录：

1. 下载网站文件

import urllib2
import os

//伪造浏览器头，模仿浏览器访问
//否则很多网站会拒绝访问 出现403错误
headers = {'User-Agent':'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6'} 

url = 'https://abc.com/newnotes/a66.mp3'

req = urllib2.Request(url, headers=headers) 

//若文件很大，请修改 timeout
f = urllib2.urlopen(req,timeout=10) 

data = f.read() 

//本地保存的文件名
local = os.path.join('/Users/mymac/Desktop/Piano','a66.mp3')

with open(local, "wb") as code:
    code.write(data)

2. 下载网站多个文件

如： http://abc.com/a1.mp3 a2.mp3 a99.mp3

import urllib2
import os


headers = {'User-Agent':'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6'} 



for i in range(1,100):
    mp3name = 'b' + str(i) +'.mp3'

    url = 'https://abc.com/newnotes/' + mp3name
    print url

    req = urllib2.Request(url, headers=headers) 

//下载出错则跳过
    try:  
        f = urllib2.urlopen(req,timeout=1000) 
    except urllib2.URLError, err:  
        print 'no file or  download error...\n'
        continue
    

    data = f.read() 

    local = os.path.join('/Users/mymac/Desktop/myfile',mp3name)


    with open(local, "wb") as code:
         code.write(data)
