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 requires a tiny Python script on the client side and a little PHP on the server side. The Python script is used to urlencode the file to be uploaded. 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":
#!/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(...);
