Post upload using wget
I like to use wget in shell scripts to upload files to remote servers over http. I use this when it isn't convenient to use scp.
This is not secure if you don't pay attention.
This requires a tiny Python script on the client side and a little PHP on the server side. The Python script is used to encode the file to be uploaded so that wget can send it as a POST request. It's a very simple script, so you can easily replace it with the language of your choice (Perl or maybe even sh).
Step 1. On the client side create a Python script called "postencode.py":
#!/usr/bin/env python import sys, urllib, base64 input_filename = sys.argv[1] postwad_filename = input_filename + ".post" datawad = base64.encodestring(file(input_filename, "rb").read()) postwad = urllib.urlencode({"filedata":datawad, "filename":input_filename}) file(postwad_filename, "wb").write(postwad) print postwad_filename
Step 2. On the server side create a PHP create a script called "upload.php":
<html><head><title>Post Upload Tool</title><body> <?php $filename = $_POST['filename']; $filedata = base64_decode($_POST['filedata']); echo "<h1>$filename</h1>"; $fout = fopen($filename,"wb"); fwrite($fout, $filedata); fclose($fout); ?> </body></html>
Step 3. Use wget to post a file to the server (note the backticks):
wget --post-file=`./postencode.py FILENAME` http://www.example.com/upload.php
Other languages for the client side
If you choose not to use Python for the postencode script then here are references for other languages.
In Perl use:
use URI::Escape; uri_escape(...);
In PHP use:
urlencode(...);
