我尝试使用Ruby Mechanize gem登录amazon partnernet，例如https://partnernet.amazon.de/：
宝石文件：

# https://github.com/sparklemotion/mechanize
gem 'mechanize'

下面的代码是一个rake任务。它在过去工作，我认为亚马逊改变了页面html所以这段代码不再工作，例如，通过改变表单name=“sign_in”的submit按钮为image type=input。

desc "Cron Task for Email Notifications"
task :email_amazon_stats => :environment do
  puts "Start: Fetch and send Amazon Sales from yesterday (#{Time.now})"

  # login to Amazon Partnernet
  a = Mechanize.new
  a.user_agent_alias = 'Mac Safari'
  a.follow_meta_refresh = true
  a.redirect_ok = true

  a.get('https://partnernet.amazon.de/') do |page|
    # Submit the login form
    page.form_with(:name => 'sign_in') do |f|
      username_field = f.field_with(:id => "username")
      username_field.value = "email@example.com"
      password_field = f.field_with(:id => "password")
      password_field.value = "somepassword"
    end.submit

    start_date  = Time.now - 1.day
    end_date    = Time.now
    my_page2 = a.get("https://partnernet.amazon.de/gp/associates/network/reports/report.html?ie=UTF8&deviceType=all&endDay=#{(end_date.strftime('%d').to_i).to_s}&endMonth=#{((end_date.strftime('%m').to_i)-1).to_s}&endYear=#{end_date.strftime('%Y').to_i.to_s}&periodType=exact&preSelectedPeriod=monthToDate&program=all&reportType=earningsReport&startDay=#{start_date.strftime('%d').to_i.to_s}&startMonth=#{((start_date.strftime('%m').to_i)-1).to_s}&startYear=#{start_date.strftime('%Y').to_s}")

    form = my_page2.form_with(:name => 'htmlReport')
    button = form.button_with(:name => 'submit.download_XML')
    xml = a.submit(form, button)

    # ASIN="3423347570"

    doc = Nokogiri::XML(xml.body)
    @sales = []
    doc.xpath("//Item").each do |item|
      @sales << {
          :sale_itemasin    => item['ASIN'],
          :sale_itemname    => item['Title'].truncate(80),
          :sale_date        => Time.at(item['EDate'].to_i).strftime("%Y-%m-%d %H:%M:%S").to_s,
          :sale_amount      => '%.2f' % item['Revenue'].gsub(',','.').to_f,
          :sale_commission  => '%.2f' % item['Earnings'].gsub(',','.').to_f
      }
    end

    earnings = 0
    @sales.each do |s|
      earnings += s[:sale_commission].to_f
    end
    @total_commission = '%.2f' % earnings
  end

  ReportsMailer.daily_dashboard(@total_commission,@sales).deliver
  puts "Done: Fetch and send Amazon Sales from yesterday (#{Time.now})"
end

有人能帮我一下吗？

我寻找类似的问题如何重组提交，但到目前为止没有任何工作。登录没有发生。（是的，PWD是正确的：-））
类似的问题，但并没有解决上面的问题：Cannot Login to Amazon with Ruby Mechanize
