How to fill a form

[Sulsa]

I need to fill form from web site, the code for this form looks like
this:

<form action="login.php" method="post" target="_top">

<input type="text" name="username" size="25" maxlength="40"
class="post" />
<input type="password" name="password" size="25" maxlength="25"
class="post" />

<input type="hidden" name="redirect"
value="" />
<input type="submit" name="login" class="mainoption"
value="Login" />

</form>

I can of course connect to a web site and download the form, i do it
like this:

import urllib2
www = urllib2.urlopen("http://www.site.com/login.php")
form_data= stronka.read()

or using httplib:

import httplib
conn = httplib.HTTPConnection("www.site.com")
conn.request("GET", "/login.php")
data1 = conn.getresponse().read()


but i can't fill and send this form is there some simple way to do it?

I'd recommend you take a look at mechanize, see

http://wwwsearch.sourceforge.net/mechanize/

and specifically at ClientForm, see

http://wwwsearch.sourceforge.net/ClientForm/

These make it easy to perform browser-like accesses to forms-based web
applications.

I want to fill only one smiple form so i would like not to use any non
standard libraries.

I want to fill only one smiple form so i would like not to use
any non standard libraries.

Then just send the HTTP "POST" request containing the fields
and data you want to submit.

That's your choice, but frankly I'd be very surprised if it wasn't
quicker to download and use mechanize/clientform than it was to put your
own solution together.

but i don't know how to post these data if i knew there there would
be no topic.

http://docs.python.org/lib/module-urllib.html

You want to look at urlopen and urlencode.

But if you mean you don't know what fields and data to use, then you
need a HTML reference, not a Python one.

When I need to learn the POST method for a form, I use wireshark
(www.wireshark.org) to capture the POST I do manually the first time.
However, I think I'm going to look into mechanize/clientform now that I
know about it.

Hope this helps,
Tom

Something like this (UNTESTED, and I can never remember all the
details, which are fiddlier than they may look):

import urllib, urllib2
query = urllib.urlencode([
("username", "sulsa"), ("password", "sulsa"),
("redirect", ""), ("login", "Login"),
])
r = urllib2.urlopen("http://example.com/login.php", query)
print r.read()


Note that urllib and urllib2 both, as their main job in life, open
URLs. urllib also has miscellaneous functions related to URLs &c. I
use urllib2 above because I know it better and because it can handle
some stuff that urllib doesn't (it's designed more for extensibility
than is urllib).
