重写（或劫持）从浏览器中的Flash（SWF）文件发出的绝对URL请求 [英] Rewrite (or hijack) an absolute URL request made from a flash (swf) file in a browser

问题描述

是否可以重写（或劫持）浏览器中Flash（swf）文件发出的绝对URL请求？

Is there a way to rewrite (or hijack) an absolute URL request made from a flash (swf) file in a browser?

例如

我有一个Flash应用程序正在请求 http://example.com/ myImage.png

I have a flash application that is requesting http://example.com/myImage.png

Flash应用程序中的代码无法更改，但我希望能够使用其他Flash或某些JavaScript将该URL编写为图片被请求请求-类似于

The code in the flash application cannot be changed but I want to be able to either use another flash or some javascript to write that URL as the image is beging requested - to something like

example.com/myImage.png?u=123456

推荐答案

您正在谈论AS2瑞士法郎的机会可以。 AVM1非常适合这种肮脏的把戏，但AVM2不允许您这样做。

You could have a chance of doing it your are talking about an AS2 swf. The AVM1 is very permissive for that kind of dirty tricks, but AVM2 won't allow you.

因此，假设使用AS2 SWF，您可以编写一个可劫持的包装SWF文件MovieClipLoader或loadMovie或原始swf所使用的任何东西（您可能必须对其进行反编译才能知道）。

So, assuming an AS2 SWF, you could write a wrapper swf that hijacks either MovieClipLoader or loadMovie or whatever the original swf is using (you might have to decompile it to know).

劫持位非常简单，例如：

The hijacking bit would be rather straight forward, something like:

_global['MovieClipLoader'] = MyClass;

一旦MyClass接到电话，您就可以添加所需的内容，然后进行实际的通话。

Once MyClass gets the calls, you add whatever you want and then make the actual call.

话虽如此，我知道_global技巧适用于自定义类，但不确定适用于MovieClipLoader之类的本机类。

Having said that, I know the _global trick works for custom classes, but not sure it does for native classes like MovieClipLoader.

对不起，这是我能提出的最好的建议：/

Sorry, that's the best I can come up with :/
