提取一些zip文件的Python錯誤

Question

我編寫了一個小應用程序，該應用程序通過鏈接提供一個zip文件（具有不同的擴展名），並將文件提取到重命名的文件夾。 出於某種原因，它爲我的一些zip文件工作，但不是爲他們所有。

我得到一個：

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' 

我的代碼是：

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() 

我的工作下載的文件：

蟒蛇download_unzip.py 「http://dl.dropbox.com/u/2971439/dae.kmz」

不工作的一個：

蟒蛇download_unzip.py 「http://dl.dropbox.com/u/2971439/rally_car_youbeq.kmz」

請注意，這兩個文件與我的OS提取正常（Ubuntu的）

固定我的問題隨着一些重碼變化：

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()
