It no longer relies on DOM detection, using network request success/failure as the primary signal to handle all types of visible and invisible Cloudflare challenges. // @author Gemini (AI Final Fix) // @license MIT // @match *://*/* // @grant GM_addStyle // @run-at document-idle // @downloadURL none // ==/UserScript== (function() { 'use strict'; // --- Configuration --- const config = { initialPosition: { bottom: '15px', right: '15px' }, panelBgColor: 'rgba(44, 62, 80, 0.95)', panelTextColor: '#ffffff', borderColor: '#3498db', opacity: '0.9', minWindowSize: { width: 400, height: 300 }, // --- NEW: Retry Logic Config --- initial_delay: 2500, // 页面加载后初次尝试前的延迟 retry_delay: 7000, // 失败后下一次重试的延迟（加长以等待CF验证） max_retries: 4, // 最大重试次数 excludePatterns: [ /(\/|&)pay(pal|ment)/i, /\/checkout|\/billing/i, /\/login|\/signin|\/auth/i, /\/phpmyadmin/i, /(\/ads\/|ad_id=|advertisement)/i, /doubleclick\.net/i, /facebook\.com\/plugins/i, /twitter\.com\/widgets/i, /\/popup|\/modal/i ] }; // A global object to track execution status per URL to handle SPAs window.cdnScriptStatus = window.cdnScriptStatus || {}; // --- Core Info Parsing Functions (Unchanged) --- function getCacheStatus(h) { const headersToCheck = [ h.get('cache-status'), h.get('x-cache-status'), h.get('x-cache'), h.get('x-edge-cache-status'), h.get('x-sucuri-cache'), h.get('x-vercel-cache'), h.get('x-qc-cache'), h.get('cf-cache-status'), h.get('x-response-cache'), h.get('x-bdcdn-cache-status'), h.get('cdn-cache'), h.get('bunny-cache-state') ]; for (const value of headersToCheck) { if (!value) continue; const upperVal = value.toUpperCase(); if (upperVal.includes('HIT')) return 'HIT'; if (upperVal.includes('MISS')) return 'MISS'; if (upperVal.includes('BYPASS')) return 'BYPASS'; if (upperVal.includes('DYNAMIC')) return 'DYNAMIC'; if (upperVal.includes('UPDATING')) return 'UPDATING'; if (upperVal.includes('STALE')) return 'STALE'; if (upperVal.includes('EXPIRED')) return 'EXPIRED'; } if (parseInt(h.get('age'), 10) > 0) return 'HIT (inferred)'; return 'N/A'; } const cdnProviders = { 'Cloudflare': { headers: ['cf-ray'], serverHeaders: ['cloudflare'], priority: 10, getInfo: (h) => ({ provider: 'Cloudflare', cache: h.get('cf-cache-status')?.toUpperCase() || 'N/A', pop: h.get('cf-ray')?.slice(-3).toUpperCase() || 'N/A', extra: `Ray ID: ${h.get('cf-ray') || 'N/A'}` }) }, 'AWS CloudFront': { headers: ['x-amz-cf-pop', 'x-amz-cf-id'], priority: 9, getInfo: (h) => ({ provider: 'AWS CloudFront', cache: getCacheStatus(h), pop: (h.get('x-amz-cf-pop') || 'N/A').substring(0,3), extra: `CF ID: ${h.get('x-amz-cf-id') || 'N/A'}` }) }, 'Fastly': { headers: ['x-fastly-request-id', 'x-served-by'], priority: 9, getInfo: (h) => ({ provider: 'Fastly', cache: getCacheStatus(h), pop: h.get('x-served-by')?.split('-').pop() || 'N/A', extra: `ReqID: ${h.get('x-fastly-request-id') || 'N/A'}` }) }, 'Akamai': { headers: ['x-akamai-transformed', 'x-check-cacheable'], serverHeaders:['AkamaiGHost'], priority: 9, getInfo: (h) => ({ provider: 'Akamai', cache: (h.get('x-check-cacheable') || getCacheStatus(h))?.toUpperCase() || 'N/A', pop: 'N/A', extra: h.get('x-akamai-transformed') ?
