[REBOL] Re: [shell core] Shell access for rebol/core on win32
From: luke:marmaladefoo at: 10-Jan-2004 15:05
Oops I spotted a mistake in my last post, python script
should be as follows. I've reincluded the rebol client too.
The script got broken when I tried to tidy it up too much...
- Luke
________PYTHON CGI SHELL SERVER SCRIPT_______
#!/c:\python22\bin\python.exe
import cgi
import win32pipe
import base64
print "Content-Type: text/plain\n\n"
#get the cgi form data
form = cgi.FieldStorage()
#assume cmd is base64 encoded
base64cmd = form["cmd"].value
cmd = base64.decodestring(base64cmd)
#open a pipe with that command
f = win32pipe.popen(cmd)
#return the response base64 encoded
print base64.encodestring(f.read())
#close the pipe
f.close()
_______END PYTHON SCRIPT___________
_______REBOL SHELL CLIENT_________
;---the function "call"
;---relies on a python CGI-script which takes one argument "cmd" (base64 encoded command)
;---and returns the result base64 encoded.
;---you will have to set shell-server-url as appropriate
shell-call: func [shell-string /local rslt shell-server-url] [
shell-server-url: http://localhost/cgi-bin/python/execute-cmd.py
rslt: read to-url rejoin [shell-server-url "?cmd=" enbase/base shell-string 64]
return to-string (debase/base :rslt 64)
]
____END REBOL SHELL CLIENT FUNCTION__
