I'm tring to unzip a buffer that is uploaded to django/python. I can
unzip the file in batch mode just fine, but when I get the buffer I get
a "BadZipfile exception. I wrote this snippet to try to isolate the
issue but I don't understand what's going on. I'm guessing that I'm
losing some header/trailer somewhere?
def unittestZipfile(filename):
buffer = ''
f = open(filename)
for i in range(22):
block = f.read()
if len(block) == 0:
break
else:
buffer += block
print len(buffer)
tmp = open('tmp.zip', 'w')
tmp.write(buffer)
tmp.close()
zf = zipfile.ZipFile('tmp.zip')
print dir(zf)
for name in zf.namelist():
print name
print zf.read(name)
