Question

我正在使用WebRequest发布到一个登录页面，该页面将我重定向到我真正需要发布的页面。

如何向此页面发帖，我已被重定向到？这是代码：

***** NEW STUFF *****

以下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

GET / signin / yahoo /？redir =％2Fpeople％2Flindieb68％2Frelationship％

GET /cookie_check.gne?pass=%2Fpeople%2Flindieb68%2Frelationship%2F&fail=register_cookies.gne

GET / people / lindieb68 / relationship /

最后一个是我需要点击按钮的地方。我应该通过所有这些GET并收集饼干吗？我会在晚餐后尝试一下让你知道。我觉得这样会有效。我会稍微更新一下。

            ShowInBrowser(strResponseData);
            return cookieContainer;
        }

Answer 1

收集上一个（登录）回复中的所有Cookie，因为其中至少有一个将是告知Yahoo您已经登录的Cookie。然后将包含您的帖子请求的Cookie包含到目标页面或任何其他与雅虎的互动。

Answer 2

在HttpWebREquest实例上将AllowAutoRedirect设置为true。

Answer 3

这变得复杂了。

简短的回答似乎是收集Cookies。出于某种原因，我虽然做不到。

POST到WebResponse返回的页面
