I enjoy using Mathematica, but as with any language they can't do everything. Nor should they. Here is a way I implemented quick FTP get routine.
Mathematica code:
Note: All communication to python program is through command line parameters.
Returns {Success} or {Failure}
----------------------------------------------------------------------
SetDirectory[NotebookDirectory[]];
mFileList=ReadList["!c:\\python27\\python.exe " <> NotebookDirectory[] <> "FtpPutFile.py 192.168.192.201 /Test/Coms Test.bin",Record]
----------------------------------------------------------------------
Python code: (I'm sure there are prettier implementations, but maybe not more simple :) )
NOTE: All text from Print statements are returned to Mathematica as a list returned from ReadList[] call in Mathematica code.
----------------------------------------------------------------------
from socket import *
from array import *
from struct import *
from string import *
from ftplib import FTP
import sys
def handleDownload(block):
file.write(block)
# print ".",
def mFtpPutFile(mHOST,mDirectory, mDirectory, mFileName):
# This will handle the data being Uploaded
try:
#print "Opening connection"
ftp = FTP(sys.argv[1]) # connect to host, default port
ftp.login() # user anonymous, passwd anonymous@
#print "Changing directory"
ftp.cwd(mDirectory)
#print 'Opening local file ' + filename
file = open(mFileName, 'rb')
#print 'Storing ' + filename
ftp.storbinary('STOR ' + mFileName, file)
# Clean up time
file.close()
#print 'Closing FTP connection'
ftp.close()
except:
print 'Failure'
else:
print 'Success'
mHOST = sys.argv[1]
mDirectory = sys.argv[2]
mFileName = sys.argv[3]
#mHOST='192.168.192.201' This is how to test the code without requiring the code to be called from command line
mFtpPutFile(mHOST,mDirectory,mFileName)
----------------------------------------------------------------------
Anyone else have cool and easy ways to extend Mathematica (Stay in Mathematica longer :) )? So far Python called this way has been a great way to accomplish some interesting things including sending and receiving small Ethernet commands.
