I am having trouble unzipping a kmz file returned from a service request.Here is an example of a service request:http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Locators/ESRI_Geocode_USA/GeocodeServer/f...I can unzip the resulting file from the above request using the winzip/winrar tools, but using the standard python zip modules fails with a data corruption error (same file in both cases). I've tried both gzip and zlib. My sample code is below.Any ideas what I may be doing wrong?Thanks, --Jason#sample program
import zlib,sys,os,gzip
input = sys.argv[1]
output = '%s.decomp' % input
if os.path.exists( output ):
os.unlink( output )
# Try zip first
insize = os.stat( input ).st_size
infile = open( input, 'rb' )
contents = infile.read( insize )
infile.close()
outfile = open( output, 'wb' )
try:
output_data = zlib.decompress( contents )
fail = 0
print 'Decompression with zip succeeded'
except Exception,e:
print 'Decompression error (zip): %s' % e
fail = 1
if not fail:
outfile.write( output_data )
outfile.close()
if fail:
os.unlink( output )
# Zip failed. Try gzip
gz = gzip.open( input, 'rb' )
outfile = open( output, 'wb' )
try:
outfile.writelines( gz )
fail = 0
print 'Decompression with gzip succeeded'
except Exception,e:
print 'Decompression error (gzip): %s' % e
fail = 1
gz.close()
outfile.close()
if fail and os.path.exists( output ):
os.unlink( output )
else:
print 'Decompressed file %s created' % output
