The flash-sound class loads MP3 files in different domains and obtains ID3 information.

Previously, we were working on an MP3 player for others, which was always used to load MP3 files from other domains. We all used sound. load method. The first parameter of this method is an MP3 address request, and the second parameter is something we usually ignore, the ID3 information can be output in the local test, but the MP3 files in different domains can be read on the server, and thus the ID3 information cannot be output at all, and then the file is searched in 9ria, it is found that the cross-origin policy file is accessed. First, the domain must have a cross-origin policy file, and second, sound. the second parameter of the load method, soundloadercontext, must be set to new soundloadercontext (1000, true). True is very important, because "specifies whether the Flash Player should be before loading the sound, download the cross-origin policy file from the server where the sound is loaded ". therefore, after this parameter is added, it is found that ID3 information is successfully read ~ Haha ~
