我一直在尝试自动登录我经常访问的网站 www.bungie.net。该网站与 Microsoft 和 Xbox Live 相关联，因此当人们登录到他们的网站时会使用 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。我已经模拟登录到其他网站，如 Facebook 和 Gmail，但 live.com 给我带来了麻烦。
无论如何，我一直在使用 Wireshark 和 Firefox 插件 Tamper Data 来尝试找出我需要发布的内容，以及我的请求中需要包含哪些 cookie。据我所知，这些是登录此站点必须遵循的步骤。
1. 访问 https://login.live.com/login.srf?wa=wsignin1.0&rpsnv=11&ct=1268167141&rver=5.5.4177.0&wp=LBI&wreply=http:%2F%2Fwww .bungie.net%2FDefault.aspx&id=42917
2. 接收 cookie MSPRequ 和 MSPOK。
3. 将表单 ID“PPSX”中的值、表单 ID“PPFT”中的值、您的用户名和密码全部发布到一个不断变化的 URL，类似于:https://login.live.com/ppsecure/post.srf?wa=wsignin1.0&rpsnv=11&ct= (该 URL 末尾有一些数字会发生变化)
4. Live.com 向用户返回一个包含更多要发布的隐藏表单的页面。客户端然后将来自表单“ANON”的值、来自表单“ANONExp”的值和来自表单“t”的值发布到 URL:http://www.bung ie.net/Default.aspx?wa =wsignin1.0
5. 发布该数据后，用户将返回各种 cookie，其中最重要的是“BNGAuth”，它是站点的登录 cookie。
我在第五步遇到问题，但这并不一定意味着我已正确完成所有其他步骤。我发布了来自“ANON”、“ANONExp”和“t”的数据，但没有返回 BNGAuth cookie，而是返回了一个名为“RSPMaybe”的 cookie 并重定向到主页。
当我查看 Wireshark 日志时，我立即注意到在我使用 Firefox 登录时和我的程序运行时的日志之间存在一些差异。可能没什么但我会在此处附上图片供您查看。在我在第四步中发布数据之前，我从站点返回了一个 HTTP 数据包。我不确定这是怎么发生的，但这一定是我在 HTTPS 步骤中做错了什么的副作用。

最佳答案
我不确定您是否仍在处理这个问题，但 Windows Live 开发网站上有很多信息可以帮助您使用 Live ID API。我没有深入研究，但他们的 Getting Started页面包含大量信息以及一个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。
您尝试做的事情听起来很有趣，以至于我很想亲自玩一玩!
