没有“http | https”的网址 [英] URL without "http|https"
问题描述
我刚从一位同事那里了解到，在链接中省略URL的http | https部分会使该URL使用它所使用的页面使用的任何方案。
<例如，如果我的页面是在 http://www.example.com 上访问的，那么我有一个链接（请注意' //'在前面）：
< a href =// www.google.com> Google< / A>
该链接将转到 http://www.google.com 。
但如果我通过 https://www.example.com 使用相同的链接，它将转到 https://www.google.com
我想在网上查询有关这方面的更多信息，但我在思考一个好的搜索短语时遇到了麻烦。如果我搜索没有HTTP的URL，返回的页面是关于这个表单的网址：www.example.com，这不是我正在寻找的。
你会称这是一个无方案的URL吗？无协议的URL？
这适用于所有浏览器吗？我在FF和IE 8中进行了测试，它在两者中均有效。这是标准的一部分，还是我应该测试更多浏览器？
协议相对网址。
您可能会在某些浏览器中收到异常的安全警告。
另请参阅 Wikipedia Protocol-relative URL 的简要定义。
At有一次，建议使用;但是要继续前进，应该避免。另请参阅StackOverflow问题，为什么要使用协议相对URL？
I just learned from a colleague that omitting the "http | https" part of a URL in a link will make that URL use whatever scheme the page it's on uses.
So for example, if my page is accessed at http://www.example.com and I have a link (notice the '//' at the front):
<a href="//www.google.com">Google</a>
That link will go to http://www.google.com.
But if I access the page at https://www.example.com with the same link, it will go to https://www.google.com
I wanted to look online for more information about this, but I'm having trouble thinking of a good search phrase. If I search for "URLs without HTTP" the pages returned are about urls with this form: "www.example.com", which is not what I'm looking for.
Would you call that a schemeless URL? A protocol-less URL?
Does this work in all browsers? I tested it in FF and IE 8 and it worked in both. Is this part of a standard, or should I test more browsers?
Protocol relative url.
You may receive unusual security warnings in some browsers.
See also, Wikipedia Protocol-relative URLs for a brief definition.
At one time, it was recommended; but going forward, it should be avoided. See also, StackOverflow question, Why use protocol-relative URLs at all?
