用浏览器登录然后ruby / mechanize接管它？

这甚至可能吗？我需要传递给机械化的东西？我可以用什么网址开始呢？

我无法管理（到目前为止）使用机械化登录一个网站所以我在想是否可以做这个小小的解决方法。我相信我可以捕获所有的cookie和其他所有内容，然后将它传递给ruby / mechanize来完成剩下的工作......

下面的屏幕截图是使用firebug（Firebug logs the POST or GET request, the response headers）

制作的

登录工作=只有一行

login that works = just one line http://i45.tinypic.com/ofivo.jpg

和用于登录的html

          

        <script type="text/javascript" src="clientscript/vbulletin_md5.js?v=3612"></script>
                    <table cellpadding="0" cellspacing="1" border="0">
                    <tr>
                        <td class="smallfont" align="left"><label for="navbar_username">User Name</label></td>
                        <td class="smallfont" align="left" colspan="2"><label for="navbar_password">Password</label></td>
                    </tr>
                    <tr>

                        <td><input type="text" class="button" name="vb_login_username" id="navbar_username" size="10" accesskey="u" tabindex="101" value="User Name" onfocus="if (this.value == 'User Name') this.value = '';" /></td>        
                        <td><input type="password" class="button" name="vb_login_password" id="navbar_password" size="10" accesskey="p" tabindex="102" /></td>
                        <td class="smallfont" align="left" valign="middle"><input type="submit" class="button" value="Log in" tabindex="103" title="Enter your username and password in the boxes provided to login, or click the 'register' button to create a profile for yourself." accesskey="s" />
                            <label for="cb_cookieuser_navbar">
                            <input type="checkbox" name="cookieuser" value="1" tabindex="103" id="cb_cookieuser_navbar" accesskey="c" />Save?</label>
                            <input type="hidden" name="s" value="" />
<input type="hidden" name="securitytoken" value="1cbc0286417d97b4eb43ee0b0c2b54e7c615e5b8" />
                            <input type="hidden" name="do" value="login" />
                            <input type="hidden" name="vb_login_md5password" />

                            <input type="hidden" name="vb_login_md5password_utf" /></td>
                    </tr>
                    </table>
      </form>
      <!-- / login form -->

登录对我不起作用

login that doesn't work for me http://i49.tinypic.com/13zcqj6.jpg

它是html 

<form class="login" method="post"> <fieldset>
<legend>Members Login</legend> 

<div>
<label for="auth_username">Username</label> <input id="auth_username" name="auth_username">
</div>

<div>
<label for="auth_password">Password</label> <input id="auth_password" name="auth_password" type="password">
</div>

</fieldset>
<div class="buttons">
<input name="auth_login" type="submit" value="Login"><p class="note"><a href="/forgotpassword">Forgot your password?</a></p>

</div>

</form>

我的脚本在两种情况下几乎相同。 

require 'rubygems'
require 'mechanize'
#agent = WWW::Mechanize.new

agent = WWW::Mechanize.new 

page = agent.get("http://www.vbulletin.org/forum/index.php")

login_form = page.form_with(:action => 'login.php?do=login')


puts 
login_form.fields.each { |f| puts "#{f.name} : #{f.value}" }    
login_form['vb_login_username'] = 'user name'
login_form['vb_login_password'] = ''

page = agent.submit login_form

output = File.open("login.html", "w") {|f| f.write(page.parser.to_html) }

您的问题很可能是因为Mechanize仅跟踪使用Set-Cookie HTTP标头创建的cookie。它无法处理JavaScript创建的cookie。

答案 1 :(得分：0)

是的，捕获cookie（例如，通过Firefox中的FireCookies插件），并手动将其传递给机械化可能适用于大多数情况。
