mechanize 経由でサイトにログインしようとしていて、すべてのフォームに入力してから送信していますが、試行するたびに同じページになってしまうため、リダイレクトされます (エラーメッセージなし)、またはフォームが送信されていません。何故ですか?
コード
require 'mechanize'
class Scraper
def initialize
@a = Mechanize.new { |agent|
agent.follow_meta_refresh = true
}
end
def login
@a.get("https://login.salesforce.com/") do |page|
red = page.forms.first do |form|
form.field_with(:type => "email").value = username
form.field_with(:type => "password").value = password
end.click_button
pp red
#puts main.title
end
end
end
s = Scraper.new
s.login
