跨站点AJAX请求 [英] Cross-site AJAX requests

问题描述

我需要从一个网站一个Ajax请求托管在另一个域中的REST Web服务。

I need to make an AJAX request from a website to a REST web service hosted in another domain.

尽管这是在Internet Explorer中工作得很好，其他浏览器如Mozilla和谷歌浏览处以更加严格的安全限制，其中规定禁止跨站点AJAX请求。

Although this is works just fine in Internet Explorer, other browsers such as Mozilla and Google Chrome impose far stricter security restrictions, which prohibit cross-site AJAX requests.

现在的问题是，我有过的领域，也没有在那里的网站托管Web服务器的控制。这意味着，我的REST Web服务必须运行在其他地方，我不能到位任何重定向机制。

The problem is that I have no control over the domain nor the web server where the site is hosted. This means that my REST web service must run somewhere else, and I can't put in place any redirection mechanism.

下面是JavaScript code，使异步调用：

Here is the JavaScript code that makes the asynchronous call:

var serviceUrl = "http://myservicedomain";
var payload = "<myRequest><content>Some content</content></myRequest>";
var request = new XMLHttpRequest();
request.open("POST", serviceUrl, true); // <-- This fails in Mozilla Firefox amongst other browsers
request.setRequestHeader("Content-type", "text/xml");
request.send(payload);

我怎么能有这样的工作，在Internet Explorer旁边的其他浏览器？

How can I have this work in other browsers beside Internet Explorer?
