我需要通过爬网登录詹金斯以收集一些数据，但是与詹金斯的来源相比，net/https获得了一个不完整的页面，这两个都是来源：

<input type="text" name="j_username" id="j_username" />
<input type="password" name="j_password" />
<input name="Submit" value="log in" class="submit-button primary" type="submit" />

16 @@page = Nokogiri::HTML(response.body)

一些额外的注释：网络具有代理，没有登录/密码；詹金斯的证书是自签名的；
我的问题是，为什么会发生以及如何修复？
预先感谢！
感谢@thetinman，@markthomas和一个同事的帮助，我已经设法登录詹金斯并通过Mechanagizize和Nokogiri来收集页面的XML：
