Python implementation of the bulk download of RFC documents

There are a lot of RFC documents, and sometimes you want to browse even if you are not connected to the Internet, so you can only download one copy and keep it locally.
I took a look at the address list, and it went like this:
(link: http://www.networksorcery.com/enp/rfc/rfc1000.txt)
.
(link: http://www.networksorcery.com/enp/rfc/rfc6409.txt)
Ha ha, very suitable for bulk download, the first thought is thunderbolt......
When it was available, I found that it only supported three digit extensions (with thunderbolt 7). I wanted to place exactly four digits...
Depressed under the initiation of their own idea!
This is a very good thing to do in python, the principle is very simple, very little code, read first is fast.
The code is as follows:
#! /usr/bin/python
'''
File : getRFC.py
Author : Mike
E-Mail : Mike_Zhang@live.com
'''
import urllib,os,shutil,time
def downloadHtmlPage(url,tmpf = ''):
i = url.rfind('/')
fileName = url[i+1:]
if tmpf : fileName = tmpf
print url,"->",fileName
urllib.urlretrieve(url,fileName)
print 'Downloaded ',fileName
time.sleep(0.2)
return fileName
# http://www.networksorcery.com/enp/rfc/rfc1000.txt
# http://www.networksorcery.com/enp/rfc/rfc6409.txt
if __name__ == '__main__':
addr = 'http://www.networksorcery.com/enp/rfc'
dirPath = "RFC"
#startIndex = 1000
startIndex = int(raw_input('start : '))
#endIndex = 6409
endIndex = int(raw_input('end : '))
if startIndex > endIndex :
print 'Input error!'
if False == os.path.exists(dirPath):
os.makedirs(dirPath)
fileDownloadList = []
logFile = open("log.txt","w")
for i in range(startIndex,endIndex+1):
try:
t_url = '%s/rfc%d.txt' % (addr,i)
fileName = downloadHtmlPage(t_url)
oldName = './'+fileName
newName = './'+dirPath+'/'+fileName
if True == os.path.exists(oldName):
shutil.move(oldName,newName)
print 'Moved ',oldName,' to ',newName
except:
msgLog = 'get %s failed!' % (i)
print msgLog
logFile.write(msgLog+'n')
continue
logFile.close()
In addition to RFC documentation, the program can be modified to do other things, such as bulk downloading of mp3s, e-books, and so on.
Ok, that's all, I hope it helped you.
