来自网络浏览器的跨域调用
我想从网站执行跨域 http 请求。我有什么选择？
Javascript 已经过时了，因为大多数浏览器不允许跨域调用。通常，解决方案是使用代理，但这不是此项目的选择。
我考虑的其他事情是使用 Flash 或 Java。还有其他我可以使用的平台吗？
I would like to execute a cross domain http request from a website. What are my options?
Javascript is out, because most browser don't allow cross domain calls. Generally the solution is to use a proxy, but that isn't an option for this project.
The other things I was thinking about would be to use Flash or maybe Java. Are there any other platforms that I could use?

“Javascript 已经过时了，因为大多数浏览器不允许跨域调用。”
不幸的是，Javascript 肯定会出现。您只需使用您喜欢的任何
srcurl 添加一个新脚本到页面即可。它被称为跨站脚本（或XSS ）。在我看来，它引入的漏洞使得浏览器监管“同源”策略的所有其他尝试都变得毫无意义。他们只是想修补一条已经掉到脚踝处的裤子上的破洞。"Javascript is out, because most browser don't allow cross domain calls."
Unfortunately, Javascript is most definitely in. You just have to add a new script to the page with whatever
srcurl you like. It's called Cross-Site Scripting (or XSS). IMO, the vulnerability it introduces renders moot all the other attempts by browsers to regulate a "same-origin" policy. They're just trying to patch a hole in a pair of pants that have already fallen down around your ankles.如果您对要向其发出跨域请求的服务器具有管理访问权限，则可以使其提供 Flash 跨域策略文件，以授予另一台或多台服务器跨域访问权限。然后，其他服务器需要使用 Flash 来发出跨域请求。
如果您正在寻找一些可以帮助您入门的东西，请查看开源 Forge 项目。它在 JavaScript 中公开了跨域 XmlHttpRequest API，因此您只需编写 JavaScript 代码：

If you have administrative access to the server you will be making a cross-domain request to, then you can make it serve a Flash cross-domain policy file that grants another server (or servers) cross-domain access. Then that other server needs to use Flash to make its cross-domain requests.
If you are looking for something to help get you started, check out the opensource Forge project. It exposes a cross-domain XmlHttpRequest API in JavaScript so you only have to write JavaScript code:

Java 和 Flash 都支持
crossdomain.xml文件，分别在 Oracle 和 Adobe 网站上进行了记录。W3C 正在制定采用不同方法的标准。当哪个系统实现这一点时，我无法预测。
Both Java and Flash support
crossdomain.xmlfiles, as documented on Oracle and Adobe sites respectively.W3C is working on a standard that takes a different approach. When that gets implemented by which systems, I cannot predict.
您必须坚持使用代理解决方案，因为 flash 和 java 与 javascript 具有相同的跨域限制。如果这仅供个人使用，据我所知，有一个选项可以使用 Flex 构建器和 falsh 播放器的调试器版本来发出跨域请求。
You will have to stick with the proxy solution because flash and java have the same cross-domain restrictions as javascript. If this is something that is only for personal use, there is an option as I know with the flex builder and the debugger version of the falsh player which can make cross-domain requests.
