我正在尝试实现一个Ruby脚本,该脚本将输入用户名和密码,然后填写另一个网站上的登录表单中的帐户详细信息,然后返回并跟随链接以检索帐户历史记录。为此,我使用了Mechanize宝石库。
我一直在遵循这里的示例,但似乎仍无法使其工作。为了让它逐步工作,我已经大大简化了它,但是一个看似简单的填写表单却阻碍着我。
以下是我的代码:

以下是我的代码:
# script gets called with a username and password for the site
require 'mechanize'
#create a mechanize instant
agent = Mechanize.new
agent.get('https://mysite/Login.aspx') do |login_page|
#fill in the login form on the login page
loggedin_page = login_page.form_with(:id => 'form1') do |form|
username_field = form.field_with(:id => 'ContentPlaceHolder1_UserName')
username_field.value = ARGV[0]
password_field = form.field_with(:id => 'ContentPlaceHolder1_Password')
password_field.value = ARGV[1]
button = form.button_with(:id => 'ContentPlaceHolder1_btnlogin')
end.submit(form , button)
#click the View my history link
#account_history_page = loggedin_page.click(home_page.link_with(:text => "View My History"))
####TEST to see if i am actually making it past the login page
#### and that the View My History link is now visible amongst the other links on the page
loggedin_page.links.each do |link|
text = link.text.strip
next unless text.length > 0
puts text if text == "View My History"
end
##TEST
end
终端错误消息:
stackqv2.rb:19:in `block in <main>': undefined local variable or method `form' for main:Object (NameError)
from /usr/local/lib/ruby/gems/1.9.1/gems/mechanize-2.5.1/lib/mechanize.rb:409:in `get'

form_with
。看起来如果你调用了agent.form_with
,你会得到那个错误。 - ramblex
