actionscript-3 - ExternalInterface 是否适用于文件 : protocol?

Question

任何人都可以确认 ExternalInterface 在 file: 上工作吗？协议(protocol)，或者指向一些说它不会的文档？

Answer 1

它开始看起来好像不起作用.. this page说:

Scripting in either direction between local HTML files and local SWF files--for example, using the ExternalInterface class--requires that both the HTML file and SWF file involved be in the local-trusted sandbox. This is because the local security models for browsers differ from the Flash Player local security model.

这就是它对本地可信沙箱的描述:

The local-trusted sandbox--Local SWF files that are registered as trusted (by users or by installer programs) are placed in the local-trusted sandbox. System administrators and users also have the ability to reassign (move) a local SWF file to or from the local-trusted sandbox based on security considerations (see Administrative user controls and User controls). SWF files that are assigned to the local-trusted sandbox can interact with any other SWF files and can load data from anywhere (remote or local).

因此，安装程序或用户都必须将 swf 放入本地受信任的沙箱中。
