托管Flash不会加载swf资源（xml，图像等）
我试图在我的unix机器上首先使用gtk2实现一个swf阅读器。 工作，我可以渲染简单的swf文件。 现在，我正在尝试使用xml配置添加配置到我的flash文件，添加图像等。失败，将无法通过geturlnotify（）。 这是我的代码：

这是我得到的输出：

谢谢！
编辑：
我试过这样的事情（代码在NPN_GetURLNotifyProc函数中）。 但随后，我的应用程序冻结在我的geturlnotifyproc中……
NPStream s; uint16 stype; memset(&s,0,sizeof(NPStream)); s.url = strdup(url); fprintf(stderr, "URL: %s\n", s.url); checkError("NPN_NewStream", pluginFuncs.newstream(instance,"text/html",&s,0,&stype)); writeStream(instance, &pluginFuncs, &s); pluginFuncs.urlnotify(instance,url,NPRES_DONE,notifyData); checkError("NPN_DestroyStream", pluginFuncs.destroystream(instance,&s,NPRES_DONE)); free((void*)s.url);
我忘了将通知添加到我的流…
NPError NPN_GetURLNotifyProc(NPP instance, const char* url, const char* target, void* notifyData) { fprintf(stderr,"[D] NPN_GetURLNotifyProc:%p, url: %s, window: %s, data: %p\n", instance, url, target, notifyData); NPStream s; uint16 stype; memset(&s,0,sizeof(NPStream)); s.url = strdup(url); s.notifyData = notifyData; fprintf(stderr, "NPP: %p URL: %s\n", instance, url); checkError("NPN_NewStream", pluginFuncs.newstream(instance,"text/html",&s,0,&stype)); writeStream(instance, &pluginFuncs, &s); checkError("NPN_DestroyStream", pluginFuncs.destroystream(instance,&s,NPRES_DONE)); free((void*)s.url); pluginFuncs.urlnotify(instance, url, NPRES_DONE, notifyData); return 0; }
我现在有一个可以运行编译flash（swf）的独立gtk应用程序。 希望它能帮助将来的某个人。 我建议做一个插件来读取另一个插件（也就是Sniffer）来实际知道调用哪个函数（“以及如何工作”）来使用一个像样的日志文件。
