我一直在尝试自动登录我常常访问的网站www.bungie.net。该站点与Microsoft和Xbox Live相关联，因此在人们登录其站点时使用Windows Live ID API。
我对创建网络蜘蛛/机器人比较陌生，我担心我误解了一些最基本的概念。我已经模拟登录到Facebook和Gmail等其他网站，但是live.com给了我一些麻烦。
无论如何，我一直在使用Wireshark和Firefox插件篡改数据来试图找出我需要发布的内容，以及我需要包含哪些我的请求。据我所知，这些是登录本网站必须遵循的步骤。
1. 访问https://login.live.com/login.srf?wa=wsignin1.0&rpsnv=11&ct=1268167141&rver=5.5.4177.0&wp= LBI＆安培; wreply = HTTP：％2F％2Fwww.bungie.net％2FDefault.aspx和ID = 42917
2. 收到MSPRequ和MSPOK的cookies。
3. 将表单ID“PPSX”中的值，表单ID“PPFT”中的值，您的用户名，密码全部发布到类似于以下内容的更改URL：https：// login.live.com/ppsecure/post.srf?wa=wsignin1.0&rpsnv=11&ct= （在该URL的末尾有一些数字会发生变化）
4. Live.com会向用户返回一个包含更多隐藏表单的页面。然后，客户端将“ANON”形式的值，“ANONExp”形式的值和“t”形式的值发布到URL：http：//www.bung ie.net/Default.aspx？wa = wsignin1.0
5. 在发布该数据后，会向用户返回各种Cookie，其中最重要的是“BNGAuth”，即该网站的登录Cookie。
我遇到麻烦的地方是第五步，但这并不意味着我已经正确完成了所有其他步骤。我发布了来自“ANON”，“ANONExp”和“t”的数据，但我没有返回一个名为“RSPMaybe”的cookie，而是返回到主页。
当我查看Wireshark日志时，我注意到当我使用Firefox登录时以及我的程序运行时，日志与我之间的区别很明显。它可能没什么但我会在这里包含图片供您查看。在第四步发布数据之前，我正从网站返回一个HTTP数据包。我不确定这是怎么回事，但它必须是我在HTTPS步骤中做错的一个副作用。

我不确定您是否仍在使用此功能，但Windows Live Development网站上有大量信息可帮助您使用Live ID API。我没有深入研究它，但他们的Getting Started页面有大量信息以及下载示例应用程序的链接，详细说明了如何以各种语言（包括C＃）使用该服务。
您可以从那里下载示例应用程序。
你想要做的事情听起来很有趣，以至于我非常喜欢自己玩这个游戏！

更改时间，看看是否得到相同的结果。
答案 2 :(得分：-2)
使用像WatiN这样的UI自动化框架比使用httpwebrequest要容易得多，除非这会破坏您的要求。使用WatiN，您正在考虑在UI上显示的内容而不是HTML上的内容。
