127.0.0.1和localhost是否被浏览器视为两个不同的域？ [英] Are 127.0.0.1 and localhost considered as two different domains by browsers?

问题描述

127.0.0.1和localhost是否被浏览器视为两个不同的域，因此强制实施跨域（同源策略）限制？

Are 127.0.0.1 and localhost considered as two different domains by browsers and therefore enforce cross-domain (same origin policy) restrictions?

我观察到它工作了一段时间（在简单的网页的情况下），不能使用基于Flex的网页。

I observed it works sometime (in case of simple web pages) and does not work with Flex based web pages.

例如：
场景I：
在一个名为page1.htm的网页中，您可以调用以下脚本：

For example: Scenario I: In a web page called page1.htm, you call a script as follows:

<script type="text/javascript" src="js/somejsscript.js"></script>

或

<script type="text/javascript" src="http://localhost/js/somejsscript.js"></script>

，您可以以 http：//localhost/page1.htm

脚本II：
您可以按如下方式调用脚本：

Scenario II: You call the script as follows:

<script type="text/javascript" src="http://127.0.0.1/js/somejsscript.js"></script>

，您可以以 http：//localhost/page1.htm

推荐答案

/ host / port（port是一个方案的默认值，如果它不存在，例如端口80为http，443为https）。同源定义为匹配方案/主机/端口。 localhost和127.0.0.1在这种情况下是不同的主机。请参见 http://en.wikipedia.org/wiki/Same_origin_policy#Origin_determination_rules

Origin is defined as a scheme/host/port (port is the default value for a scheme if it doesn't exist, e.g. port 80 for http, 443 for https). Same-origin is defined as a matching scheme/host/port. "localhost" and "127.0.0.1" are different hosts in this case. See http://en.wikipedia.org/wiki/Same_origin_policy#Origin_determination_rules
