爲什麼lxml.html.parse（）結尾的斜槓很重要？

我使用lxml來刮取html。此代碼有效。爲什麼lxml.html.parse（）結尾的斜槓很重要？

lxml.html.parse("http://google.com/")

此代碼沒有。

lxml.html.parse("http://google.com")

爲什麼URL末尾的斜槓很重要？謝謝。

要清楚，這裏是python從後面的代碼給我的錯誤日誌。

它對我有或沒有'/'工作正常。 – RanRag 2012-02-16 00:10:28

有趣。在Python解釋器中，'http：// google.com /'適用於我，但不適用'http：// google.com'。 – dangerChihuahua007 2012-02-16 00:11:44
