编辑:我开始工作它不会下载任何东西......
所以这是我现在简化的代码:
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')
这是我的输出:
'250 "/Leisure Arts - Images": is current directory.'
'226 Transfer complete. 0 bytes in 0.00 sec. (0.000 Kb/s)'
原帖: 好吧所以我一整天都在搞乱这件事。我是Python FTP的新手。所以我在这里搜索了一下,然后来了:
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
因此,在将除以零之前,我已将误差缩小到直线。这是错误:
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'
因此,如果您按照代码操作,您将看到目录中的图像IS,因为如果在我的代码第一行的目录列表中找到了image_name_we_want,则会设置该图像。而且我知道它就在那里,因为我自己正在看FTP网站......那里很奇怪。因此,在所有这些过程中的某些时刻,我得到的图像是本地保存的,这是最理想的,但我早就忘记了我曾经做过的事情。无论哪种方式,为什么当它在清单中清楚地找到它时,它认为图像不存在。
好的,所以我接受了这个建议,现在我得到了:
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
所以它得到了第一个图像,我认为它确实已损坏,但是当它继续处理下一个要处理的图像时,它会在文件对象上抛出该错误。所以这就是我如何改变它以及其他未放在首位的代码:
# 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
答案 0 :(得分:1)
您正在阅读该文件而不是编写文件。
而不是open(image_name_we_want, "rb")
使用open(image_name_we_want, "wb")
[编辑] 如果您只是从ftp服务器获取,那么您也可以尝试:
import urllib2
fh = urllib2.urlopen('ftp://server/path/file.png')
file('file.png', 'wb').write(fh.read())
另外,对于一个完整的工作示例,请阅读:http://docs.python.org/library/ftplib.html
您在write
open()
