我正在尝试从我公司使用的网络服务中自动获取某个报告。我一直在使用Mechanize gem，我能够使用它从同一服务获得其他报告。
当我提交生成报告的表单时，我回复的所有内容都是CSV的标题。显然，它应该返回更多。
我已经使用Chrome开发工具查看每个字段的预期值，并且我已经模仿了它们。不过，无论我尝试什么，我都无法让服务返回预期值。
我该怎么办？我可能做错了什么？
编辑：有问题的代码
@loginpage = 'service_uri'
agent = Mechanize.new
login_page = agent.get @loginpage
login_form = login_page.form
email_field = login_form.field_with(name: "Email")
password_field = login_form.field_with(name: "Password")
email_field.value = 'service_login'
password_field.value = 'service_password'
page = login_form.submit
transaction_page = page.link_with(text: 'Transaction History').click
