python如何获取svn路径是文件还是文件夹

Answer 1

GetFilesFromSVN.py
#----------------------------------------------
# Author : Jeff Yu
# Date : 2012-8-13
# Function : get files from SVN
#----------------------------------------------

#----------------------------------
# Step1: Get INFO
#----------------------------------
import sys,ConfigParser

try:
configFile = open("config.ini","r")
except IOError:
print "config.ini is not found"
raw_input("")
sys.exit()

config = ConfigParser.ConfigParser()
config.readfp(configFile)
configFile.close()

# get baseurl
try:
baseurl = config.get("INFO","baseurl")

# incase last "/" is missing in baseurl
baseurl = baseurl.rstrip("/")
baseurl = "%s/"%baseurl
except ConfigParser.NoOptionError:
print "baseurl is not found under section INFO in config.ini."
raw_input("")
sys.exit()

# get user
try:
user = config.get("INFO","user")
except ConfigParser.NoOptionError:
meg = "user is not found under section INFO in config.ini."
raw_input("")
sys.exit()

# get passwd
try:
passwd = config.get("INFO","passwd")
except ConfigParser.NoOptionError:
meg = "passwd is not found under section INFO in config.ini."
raw_input("")
sys.exit()

# get fileList
try:
fileList = config.get("INFO","fileList")
except ConfigParser.NoOptionError:
meg = "fileList is not found under section INFO in config.ini."
raw_input("")
sys.exit()

#----------------------------------
# Step2: Auth
#----------------------------------
import urllib2
realm = "Subversion Repositories"
auth = urllib2.HTTPBasicAuthHandler()
auth.add_password(realm, baseurl, user, passwd)
opener = urllib2.build_opener(auth, urllib2.CacheFTPHandler)
urllib2.install_opener(opener)

#----------------------------------
# Step3: Create Folder
#----------------------------------
import os
folderName = "svnFile"
if not os.path.exists(folderName):
os.mkdir(folderName)

#----------------------------------
# Step4: Get Files
#----------------------------------
fr = open(fileList,'r')
for i in fr:
i = i.strip("\n")
i = i.strip(" ")

# ignore the blank line
if i != "":
url = "%s%s"%(baseurl,i)

try:
data = urllib2.urlopen(url)

fw = open("%s/%s"%(folderName,i),'w')
fw.write(data.read())
fw.close()

print "Download: %s."%i

except urllib2.HTTPError, e:
# HTTPError is a subclass of URLError
# need to catch this exception first
mesg = str(e).split(" ")
errCode = mesg[2].rstrip(":")

if errCode == "401":
# HTTP Error 401: basic auth failed
print "Can not login in, please check the user and passwd in config.ini."
break
elif errCode == "404":
# HTTP Error 404: Not Found
print "Not Found: %s"%i
else:
print e
print "Failed to download %s"%i

except urllib2.URLError:
# 1.SVN server is down
# 2.URL is not correct
print "Please check SVN Server status and baseurl in config.ini."
break

fr.close()
raw_input("")
config.ini

[INFO]
baseurl = https://xxx/xxx/xxx/xxx/
user = 用户名
passwd = 密码
fileList= fileList.txt
fileList.txt

aaaaa.txt
bbbbb.txt
ccccc.txt
使用方法:
1.配置config.ini，配置好需要check out文件所在文件夹的URL(baseurl)，用户名(user)，密码(passwd)和存储文件列表的文件名称(fileList)

2.将要check out的文件列表放在文本文件里面(fileList.txt)，每一个文件占一行.

3.双击GetFilesFromSVN.py运行,下载的文件将放在当前文件夹下用过名为svnFile的文件夹里面.

PS:获取realm

在这个脚本中，我hardcode了一段代码(064行) realm = "Subversion Repositories"

关于这个realm，可以使用下面脚本获取：
import urllib2
import sys

url = '这里写URL'

username = '这里写用户名'
password = '这里写密码'

req = urllib2.Request(url)
try:
handle = urllib2.urlopen(req)
except IOError, e:
pass
else:
print "This page isn't protected by authentication."
sys.exit(1)

getrealm = e.headers['www-authenticate']
print getrealm
