i wrote a small app that downloads a zip file (with a different extension) when provided by a link and extracts the file to a renamed folder. For some reason its working for some of my zip files, but not for all of them.
I get a :
Traceback (most recent call last):
File "download_unzip.py", line 48, in <module>
main()
File "download_unzip.py", line 42, in main
shutil.move(unzip_file(temp_kmz),'temp_extracted/')
File "download_unzip.py", line 26, in unzip_file
fd = open(name, 'w')
IOError: [Errno 2] No such file or directory: 'models/model.dae'
My code is :
import sys , urllib , zipfile , os.path , argparse , shutil
parser = argparse.ArgumentParser(description="Download and Unzip")
parser.add_argument('url', help='The action to take (e.g. install, remove, etc.)')
args = parser.parse_args()
print args.url
url = args.url
temp_kmz="temp_kmz"
def unzip_file(path):
zfile = zipfile.ZipFile(path)
extracted_filename = zfile.infolist()[0].filename[:-1]
for name in zfile.namelist():
(dirname, filename) = os.path.split(name)
#print "Decompressing " + filename + " on " + dirname
if filename == '':
# directory
if not os.path.exists(dirname):
os.mkdir(dirname)
else:
# file
fd = open(name, 'w')
fd.write(zfile.read(name))
fd.close()
zfile.close()
return extracted_filename
def download_file():
urllib.urlretrieve (url, temp_kmz)
return True
def main():
if (download_file()):
print "Now deleting temp..."
shutil.rmtree('temp_extracted/')
print "unzipping.. and renaming folder"
shutil.move(unzip_file(temp_kmz),'temp_extracted/')
print "Finished!!"
else:
print "Error downloading file"
main()
my working downloaded file:
python download_unzip.py " http://dl.dropbox.com/u/2971439/dae.kmz "
The one that is not working:
python download_unzip.py " http://dl.dropbox.com/u/2971439/rally_car_youbeq.kmz "
Please note that both files extract properly with my OS (Ubuntu)
fixed my problem with some heavy code changes:
import urllib2 ,argparse, shutil, urlparse , os , zipfile, os.path
from zipfile import ZipFile as zip
parser = argparse.ArgumentParser(description="Download and Unzip")
parser.add_argument('url', help='The action to take (e.g. install, remove, etc.)')
args = parser.parse_args()
print args.url
url = args.url
temp_kmz="temp_kmz"
def extractAll(zipName):
z = zip(zipName)
for f in z.namelist():
if f.endswith('/'):
os.makedirs(f)
else:
z.extract(f)
def download(url, fileName=None):
def getFileName(url,openUrl):
if 'Content-Disposition' in openUrl.info():
# If the response has Content-Disposition, try to get filename from it
cd = dict(map(
lambda x: x.strip().split('=') if '=' in x else (x.strip(),''),
openUrl.info()['Content-Disposition'].split(';')))
if 'filename' in cd:
filename = cd['filename'].strip("\"'")
if filename: return filename
# if no filename was found above, parse it out of the final URL.
return os.path.basename(urlparse.urlsplit(openUrl.url)[2])
r = urllib2.urlopen(urllib2.Request(url))
try:
fileName = fileName or getFileName(url,r)
with open(fileName, 'wb') as f:
shutil.copyfileobj(r,f)
finally:
r.close()
def main():
download(url,temp_kmz)
extractAll(temp_kmz)
main()
