为什么图标不可见 [英] Why is favicon not visible

问题描述

我有一个脚本，它允许根据网址来显示网站图示：例

I have a script which allows to display favicons based on the url: Example

如果你看一下例子，你会看到两个环节，一个连接到谷歌和其他当红荷兰新闻网站。正如你所看到的谷歌图标是由脚本检索，而另一个则不是。这怎么可能？是什么原因造成的？如果我去的网站，我可以看到他们有一个图标。我可以在code更改为检索该图标？

If you look at the example you will see two links, one linking to Google and the other to a popular dutch news website. As you can see the Google favicon is retrieved by the script while the other is not. How is this possible? What is causing this? If I go to the website I can see they do have a favicon. What can I change in the code to retrieve this favicon?

推荐答案

由于图标为nu.nl下 http://www.nu.nl/images/favicon.ico

Because favicon for nu.nl is stored under http://www.nu.nl/images/favicon.ico
