【问题描述】：
我正在尝试通过网络抓取我的 Facebook 页面以获取我所有朋友的生日。由于 facebook 使用 ajax 调用在“生日活动”页面中加载朋友姓名，我查看了 chrome 开发工具中的网络活动，以了解它在哪里以及如何进行 xhr 调用以及响应数据如何。
这些电话的回应对我来说没有任何意义。他们看起来像是被混淆了或其他什么......如何使用我在进行 xhr 调用时获得的响应数据来提取我在网站上看到的数据？
这是响应数据：

似乎 facebook 网站以某种方式解释了此响应数据并在页面上呈现了朋友的名字。我想要的数据是一直向下滚动后最终呈现的网页。但是当我使用python的“请求”模块或查看页面源时，这些HTML内容大部分都不存在。
我该如何解决这个问题？
【问题讨论】：
-
你知道在 facebook 上不允许抓取，对吧？如果你想得到朋友的生日，唯一的办法就是让他们授权一个具有 user_birthday 和 user_friends 权限的应用程序。
-
是的，我知道，我没有用这个制作任何生产应用程序，只是为了我的个人学习和项目之类的东西。
-
不管你想用什么数据，都不允许抓取。更好地学习使用图形 api 可能的东西 ;)
