机械化表单提交退货加载页面，而不是所需结果页面

Question

在使用Mechanize（在Ruby中）自动输入搜索字段并自动单击提交按钮后，我无法返回结果页面。

问题是返回了3秒的加载页面，而不是几秒钟后加载的实际结果页面。

在那里睡觉显然是行不通的。

require 'mechanize'

agent = Mechanize.new
url = 'https://www.intelius.com'
agent.get(url) do |page|
    form = page.forms.first

    username_field = form.field_with(:id => "peopleSearch_firstName")
    username_field.value = "John"
    password_field = form.field_with(:id => "peopleSearch_lastName")
    password_field.value = "Lee"
    city_state_field = form.field_with(:id => "peopleSearch_cityState")
    city_state_field.value = "Van Nuys, CA"

    page_logged_in = form.submit
    sleep(5)
    puts page_logged_in.body
end
