嗨，

我已经能够通过抓住GALX值成功登录到YouTube的一些问题。当我打印出位于代码底部的http://youtube.com的内容时，它显示正常，它显示我已登录..但如果要打印出视频网址的内容（在代码中注释如下）该页面只是空白和白色..这让我疯狂，任何人都知道为什么会发生这种情况？

Answer 1

问题之一就是标题，帖子栏和cookie。虽然看起来你已经整理了cookies的一部分，但请确保使用LiveHTTPHeaders（Firefox的扩展）来嗅探并查看发送了哪些额外的头信息，以及是否通过隐藏表单发送更多的发布数据等。

其他使用的cookies也显示在这里。尽管curling SETOPT_COOKIEJAR主要处理cookie，但由于这种自动化，cookie管理有点困难。

因此，请确保您在登录后在YouTube上加载视频页面时，仔细检查发送的信息并添加这些字段以进行卷曲。 祝你好运。
