【问题描述】：

我正在尝试使用 Ruby gem Mechanize 登录亚马逊。我总是被踢回登录页面而没有任何错误消息。我想知道这是否是 Mechanize 的错误，或者亚马逊是否阻止了这种访问。我有下面的代码，你可以通过 irb 来测试。

@mechanizer = Mechanize.new

@mechanizer.user_agent_alias = 'Mac Safari'

@page = @mechanizer.get("https://www.amazon.com/ap/signin?_encoding=UTF8&openid.assoc_handle=usflex&openid.return_to=https%3A%2F%2Fwww.amazon.com%2Fgp%2Fyourstore%3Fie%3DUTF8%26ref_%3Dpd_irl_gw&openid.mode=checkid_setup&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&openid.pape.max_auth_age=0&openid.ns.pape=http%3A%2F%2Fspecs.openid.net%2Fextensions%2Fpape%2F1.0&openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select")

form = @page.form_with(:id => "ap_signin_form")

field = form.field_with(:name => "email")
field.value = "[e-mail]"

radiobutton = form.radiobutton_with(:name => 'create', :value => '0')
radiobutton.check

button = form.button_with(:id => "signInSubmit")

@page = form.submit button

感谢您的帮助。

【参考方案1】：

试试这个，

#!/usr/bin/env ruby

require "rubygems"
require "mechanize"

class AmazonCrawler
  def initialize
    @agent = Mechanize.new do |agent|
      agent.user_agent_alias = 'Mac Safari'
      agent.follow_meta_refresh = true
      agent.redirect_ok = true
    end
  end

  def login
    login_url = "https://www.amazon.com/ap/signin?_encoding=UTF8&openid.assoc_handle=usflex&openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&openid.mode=checkid_setup&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&openid.ns.pape=http%3A%2F%2Fspecs.openid.net%2Fextensions%2Fpape%2F1.0&openid.pape.max_auth_age=0&openid.return_to=https%3A%2F%2Fwww.amazon.com%2Fgp%2Fyourstore%2Fhome%3Fie%3DUTF8%26ref_%3Dgno_signin"
    @agent.get(login_url)
    form = @agent.page.forms.first
    form.email = "[e-mail]"
    form['ap_signin_existing_radio'] = "1"
    form.password = "password"
    dashboard = @agent.submit(form)
    File.open('dashboard.html', 'w') |file| file << dashboard.body 
  end
end

AmazonCrawler.new.login

mechanize documentation 有一些很酷的例子。这个cheat sheet 也很方便快速参考。

【讨论】：

我正在尝试做类似的事情，但没有取得多大成功。上面编写的代码仍会将您重定向回登录页面。有什么想法吗？

我也想知道

@fffanatics, @Zack 我已更新代码以将页面打印到文件中。确保更改 form.email 和 form.password 的值以匹配您的 Amazon 用户凭证。它仍然为我工作。

所以这绝对适用于 amazon.com。我试图登录 developer.amazon.com 而不是主网站。我无法通过 Mechanize 让它工作，但能够通过 Watir 和 Headless gems 让它工作
