Can I upload an object in memory to FTP using Python?
Here's what I'm doing now:
mysock = urllib.urlopen('http://localhost/image.jpg') fileToSave = mysock.read() oFile = open(r"C:\image.jpg",'wb') oFile.write(fileToSave) oFile.close f=file('image.jpg','rb') ftp.storbinary('STOR '+os.path.basename('image.jpg'),f) os.remove('image.jpg')
Writing files to disk and then imediately deleting them seems like extra work on the system that should be avoided. Can I upload an object in memory to FTP using Python?
Because of duck-typing, the file object (
f in your code) only needs to support the
.read(blocksize) call to work with
storbinary. When faced with questions like this, I go to the source, in this case lib/python2.6/ftplib.py:
def storbinary(self, cmd, fp, blocksize=8192, callback=None): """Store a file in binary mode. A new port is created for you. Args: cmd: A STOR command. fp: A file-like object with a read(num_bytes) method. blocksize: The maximum data size to read from fp and send over the connection at once. [default: 8192] callback: An optional single parameter callable that is called on on each block of data after it is sent. [default: None] Returns: The response code. """ self.voidcmd('TYPE I') conn = self.transfercmd(cmd) while 1: buf = fp.read(blocksize) if not buf: break conn.sendall(buf) if callback: callback(buf) conn.close() return self.voidresp()
