使用xmlhttp跨域编写脚本 [英] Cross domain scripting with xmlhttp

问题描述

之前已经出现但我不确定最新版本的IE

和FF是否会改变答案。


运行的脚本网页由 http://foo.something.com 提供

应该能够做到

xmlhttp.open（" GET"，" http：//bar.something.com" true）


但是在Firefox 1.5中，我得到了Permission denied错误


为什么会这样？域名是something.com所以我不是跨域，

所以它为什么抱怨？


谢谢

This has come up before but I am not sure if the latest versions of IE
and FF change the answer.

A script running on a webpage served up by http://foo.something.com
should be able to do
xmlhttp.open("GET","http://bar.something.com",true)

But in Firefox 1.5, I get the Permission denied error

Why is this? The domain is something.com so I am not crossing domains,
so why is it complaining?

Thanks

你是。阅读SOP（再次）：


< URL：http：//www.mozilla.org/projects/security/components/same-origin.html>

所以为什么抱怨？

[...]

xmlhttp.open("GET","http://bar.something.com",true)

You are. Read on the SOP (again):

<URL:http://www.mozilla.org/projects/security/components/same-origin.html>
so why is it complaining?

你忘了做


document.domain =" something。 com" ;;


之前。

You forgot to do

document.domain = "something.com";

before.
