[Mechanize-users] newbie question with login form

hi,

i''m just starting to work with this incredible tool...

but i got a first problem with the login process

i''m logging on my app like this :

------

@agent = WWW::Mechanize.new { |a| a.log = Logger.new("mech.log") }

@agent.user_agent_alias = ''Mac Safari''
@page = @agent.get("http://myappAdress/")
  
@form = @page.forms.first

@form[''form_login''] = ''myLog''
@form[''form_password''] = ''myPass''

@page = @agent.submit(@form, @form.buttons.first)

put @page.body

----

Identification process is done , i can see it in my application log, but 
the page displayed is still the login form.

here is the mechanize log .

Your code looks fine!  There could be a couple issues that I can think
of right of the bat.  First, make sure that you are submitting all of
the correct data.  The way that I typically verify this is by using the
livehttpheaders plugin for Firefox (firebug may work as well), and
comparing what live httpheaders says to what my mechanize log says.
  
  http://livehttpheaders.mozdev.org/

Second, is there javascript on the page that modifies some of the input
fields?  If so, you''ll need to reproduce its functionality.

I hope that helps!

[Mechanize-users] newbie question with login form

hi aaron,

thanks for your help !

i checked my httpheaders and didn''t find any problem...

but just a question, i can see a '' pmv_ck_session ''  and a 
''pmv_ck_view_conf'' cookies in response-header: set-cookie.

and in request_header i just have one of both,

request-header: cookie =>
pmv_ck_view_conf=YToxOntzOjQ6ImxhbmciO3M6MTI6ImZyLXV0Zi04LnBocCI7fQ%3D%3D

maybe application is waitting for this cookie to authenticate me ?

how to add the '' pmv_ck_session '' session cookie on each
request ?
