Problem with Mechanize

Zhang Zhai

10/1/2008 4:23:00 PM

Hi,

I want to use Mechanize to login a sns site.Here is my test code.

require 'rubygems'
require 'mechanize'

class Kaixin
def initialize(auth, verbose = false)
@auth = auth
@verbose = verbose
@agent = WWW::Mechanize.new
@agent.redirect_ok = true
end

def login

page = @agent.get('http://www.kaixin001...)

login_form = page.forms.first
login_form.email = @auth['email']
login_form.password = @auth['password']
page1 = @agent.submit(login_form)

pp page1 if @verbose
end

end

auth = {'email' => 'xxx@gmail.com',
'password' => 'xxx'}
kx = Kaixin.new(auth, true)
kx.login


I use most of the demo code.So i cant see whats the problem.If i type
the error password,its no page error.if i type the correct pwd,then it
goes wrong,I find the page use the redirect from "/login" to "/home"
,does this matter?

Here is the output of netbeans:

c:/ruby/lib/ruby/gems/1.8/gems/mechanize-0.8.3/lib/www/mechanize/page.rb:118:in
`bases': undefined method `search' for nil:NilClass (NoMethodError)
