window.fetch = function(...args) {
if (args[0] && args[0].includes('.m3u8')) {
console.log('🎬 M3U8 Found:', args[0]);
}
return originalFetch.apply(this, args);
};
const originalOpen = XMLHttpRequest.prototype.open;
XMLHttpRequest.prototype.open = function(method, url) {
if (url && url.includes('.m3u8')) {
console.log('🎬 M3U8 Found:', url);
}
return originalOpen.apply(this, arguments);
};
console.log('✅ M3U8 监听已启动,请播放视频...');
