Flickr 自动化适用于 Flickr API 中不可用的操作（例如添加联系人）

Question

编辑：我添加了赏金，如果有人可以帮助我找出我做错了什么，那就全是你的了。

而且，我真的不在乎这是如何完成的。如果有一个库可以提供帮助，或者类似的东西那就太好了。

由于不涉及验证码，理论上我应该能够登录 Flickr 并通过类似于以下的代码添加联系人...正确的？

当我运行这段代码及其许多变体时，当我到达我应该提交表单以验证我正在添加联系人的地方时，它要求我登录。这是唯一可能是我失败的事情收集正确的cookie？

我有 IEHTTPHeader 供 IE 查看实际发生的情况，并且我正在尽力模拟它。除非我不明白某些事情，否则我找不到哪里出错了。

Flickr API 无法执行此操作

我只想登录并添加预定义联系人。

Answer 1

我已经对 perl 的 WWW:Mechanize 库做了类似的事情，请研究一下。

您可以使用 Flickr API，而不是进行屏幕抓取并让程序员的生活变得艰难。 。您可能还会发现这篇博文很有帮助。
