CGI question

[Dan Stromberg]

What's the best way of converting this:

'hide\\?http://www.dedasys.com/articles/prog...\x012005-07-20
14:48'

....to something easily usable in a python CGI script?

Thanks!

easily usable for what purpose?

if you want to extract the URL that seems to be hidden in that string,
something like:

url, junk = text.split("\x01", 1)
junk, url = url.split("\\?", 1)

should work.

Um, yeah. I can work out this sort of thing.

But I thought there might be a python module intended for parsing inputs
to CGI scripts? Sometimes using a pre-written module can contend with
issues you didn't know where going to come up...

Thanks!

Generally, input to CGI scripts are done via the Common Gateway
Interface (CGI). The cgi module does those things. Your example
doesn't look anything like a CGI string, though. Maybe if you told us
where it came from, we could recommend a module for dealing with such.

This is great, but is there no standard python module for taking
apart command line arguments to a CGI script? I'm not eager to reinvent
the wheel, at least not on this project :)

command-line arguments to CGI scripts?

I'm probably dense, but doesn't CGI scripts usually get their arguments via
environment variables and stdin ? and chr(1) and "hide\?" sure don't look
like standard URL separators to me...

if you want standard CGI argument handling, the "cgi" module contains all
the tools you need.

This looks like precisely what I need for part of what I need to do.

I'm stoked that it knows how to take apart the "?" stuff.

I'm still wondering though, if there's some part of the python standard
modules that will convert those % escapes to ASCII or similar - and
perhaps any other conversions that I don't yet realize I need to handle...

Thanks!

I believe that functionality is provided by the quote/unquote functions
in the urllib module:
