我正在使用 WebRequest 发布到登录页面，该页面将我重定向到我真正需要发布的页面。
我如何发布到我被重定向到的这个页面？这是代码：
*****新的东西*****
这是我发布到登录页面后发生的事情： GET /config/validate?.src=flickr&.pc=5134&.scrumb=6l14Ni2Pz3j&.pd=c%3DE0.GahOp2e4MjkX.5l2HgAoLkpmyPvccpVM-&.intl=us&.done= http%3A%2F%2Fwww.flickr.com%2Fsignin%2Fyahoo%2F%3Fredir%3D%252Fpeople%252Flindieb68%252Frelationship%252F
获取 /signin/yahoo/?redir=%2Fpeople%2Flindieb68%2Frelationship%
GET /cookie_check.gne?pass=%2Fpeople%2Flindieb68%2Frelationship%2F&fail=register_cookies.gne
获取 /people/lindieb68/relationship/
最后一个是我需要单击按钮的地方。我应该通过所有这些 GET 并收集 cookie 吗？我会在晚饭后试一试，然后告诉你。我觉得这会奏效。我会在一点点更新。
