Python FTP grabbing and saving images issue
EDIT: I got it working it just won't download anything...
So here is my code simplified now:
notions_ftp = ftplib.FTP(ftp_host, ftp_user, ftp_passwd)
folder = "Leisure Arts - Images"
notions_ftp.cwd(folder)
image = open("015693PR-com.jpg","wb")
notions_ftp.retrlines("RETR 015693PR-com.jpg", image.write)
send_image = open("015693PR-com.jpg", 'r')
And Here is my output:
'250 "/Leisure Arts - Images": is current directory.'
'226 Transfer complete. 0 bytes in 0.00 sec. (0.000 Kb/s)'
Original Post: OK So I have been messing with this all day long. I am fairly new to Python FTP. So I have searched through here and came up w/ this:
images = notions_ftp.nlst()
for image_name in image_names:
if found_url == False:
try:
for image in images:
ftp_image_name = "./%s" % image_name
if ftp_image_name == image:
found_url = True
image_name_we_want = image_name
except:
pass
# We failed to find an image for this product, it will have to be done manually
if found_url == False:
log.info("Image ain't there baby -- SKU: %s" % sku)
return False
# Hey we found something! Open the image....
notions_ftp.retrlines("RETR %s" % image_name_we_want, open(image_name_we_want, "rb"))
1/0
So I have narrowed the error down to the line before I divide by zero. Here is the error:
Traceback (most recent call last):
File "<console>", line 6, in <module>
File "<console>", line 39, in insert_image
IOError: [Errno 2] No such file or directory: '411483CC-IT,IM.jpg'
So if you follow the code you will see that the image IS in the directory because image_name_we_want is set if found in that directory listing on the first line of my code. And I KNOW it's there because I am looking at the FTP site myself and ...it's freakin there. So at some point during all of this I got the image to save locally, which is most desired, but I have long since forgot what I used to make it do that. Either way, why does it think that the image isn't there when it clearly finds it in the listing.
OK so I took the 开发者_如何学Csuggestion and now I get:
14:01:18,057 ERROR [pylons-admin] Image to big or corrupt! Skipping Image for product sku: 411483
14:01:18,057 ERROR [pylons-admin] Image to big or corrupt! Skipping Image for product sku: 411483
Traceback (most recent call last):
File "<console>", line 6, in <module>
File "<console>", line 40, in insert_image
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/ftplib.py", line 418, in retrlines
callback(line)
TypeError: 'file' object is not callable
>>> 14:01:24,694 INFO [pylons-admin] Script Done! Updated 0 Products w/ Images
So it got the first image, which I think really is corrupt, but then when it goes on to the next one to be processed it throws that error on the file object. So here is how I changed it and the rest of the code not put here in the first place:
# Hey we found something! Open the image....
f = open(image_name_we_want, "wb")
notions_ftp.retrlines("RETR %s" % image_name_we_want, f)
send_image = open(image_name_we_want, 'r')
# ...and send it for processing
try:
image_id = product_obj.set_image(send_image, 5, 1)
except IOError, error:
log.error("Image to big or corrupt! Skipping Image for product sku: %s" % sku)
image_id = False
else:
if image_id == False:
log.error("Could not Insert the image for product sku: %s" % sku)
f.close()
return False
else:
f.close()
os.remove(image_name_we_want)
return True
You're reading the file instead of writing it.
So instead of open(image_name_we_want, "rb")
use open(image_name_we_want, "wb")
[edit] If you're simply fetching from an ftp server than you could also try this:
import urllib2
fh = urllib2.urlopen('ftp://server/path/file.png')
file('file.png', 'wb').write(fh.read())
Also, for a fully working example read this: http://docs.python.org/library/ftplib.html
You're also missing the write
after the open()
