跨站点XMLHTTP（XDomainRequest） [英] Cross-Site XmlHttp (XDomainRequest)

问题描述

我正在写一个基于Web的工具，我的公司，它正在流失本地Intranet和在IE8上运行。我相信，因为该公司的电脑都是在国有企业，没有人有控制权，除非IT部门的浏览器设置，他们将不会做任何改变，至少在我们需要它的期限。

I'm writing a web-based tool for my company and it is running off the local intranet and running in IE8. I believe since the company computers are in a SOE, nobody has control over the browser settings except the IT department and they will be unlikely to make any changes, at least not in the timeframe we need it.

我有一个XMLHTTP请求，这是在受信任的站点（也对本地Intranet）的URL，但是当我发送请求，我得到一个异常：访问被拒绝，当我捕捉异常并输出到我的网页，我得到类型错误：访问被拒绝。

I have an XmlHTTP request to a URL which is in "Trusted Sites" (also on the local intranet), but when I send the request, I get an exception: "Access is denied", and when I catch the exception and output it to my page, I get "TypeError: Access is denied".

有没有什么办法可以让IE8完成这个AJAX请求？

Is there any way I can get IE8 to complete this AJAX request?

编辑：经进一步研究，事实证明，这个问题可能没有什么关系受信任的站点/本地Intranet毕竟。 Apparenly你不能做跨域XMLHTTP请求。我的系统是通过一个IP地址进行访问，而我的AJAX脚本的目标网站（还是本地）域，它解析为一个不同的IP地址。不幸的是我已经试着写一个PHP脚本将获取页面从服务器端，但它也拒绝无需用户名/密码进行连接。

Upon further researching, it turns out that the problem may not have anything to do with trusted sites/local intranet after all. Apparenly you can't do cross-domain XmlHttp requests. My system is accessed by an IP address, whereas the target site of my AJAX script is (still local) a domain, which resolves to a different IP address. Unfortunately I've already tried writing a PHP script which will get the page from the server-end, however it also refuses to connect without a username/password.

目前这个阶段，我愿意就如何解决这个问题的任何哈克建议。如果我能得到这个功能工作，这将节省手动输入数据我们天。

At this stage I'm open to any hacky suggestions on how to get around this. If I can get this function to work, it will save us days of manually inputting data.

推荐答案

由于IE8不支持的 CORS 你要么做代理或让与的 JSONP 或得到下相同的IP的一切。

Since IE8 does not support CORS you either have to do a proxy or make the request with JSONP or get everything under the same IP.
