二、浏览器内核嵌入
2.1 CEF框架介绍
CEF（Chromium Embedded Framework）是一个将Chromium浏览器内核嵌入到应用程序的开源框架。它支持Windows、macOS、Linux等多个平台。
2.2 初始化代码
// main.cpp
#include "include/cef_app.h"
#include "include/cef_client.h"
#include "include/cef_browser.h"
class SimpleApp : public CefApp {
public:
void OnBeforeCommandLineProcessing(
const CefString& process_type,
CefRefPtr<CefCommandLine> command_line) override {
// 禁用GPU加速（降低资源占用）
command_line->AppendSwitch("disable-gpu");
// 禁用插件
command_line->AppendSwitch("disable-plugins");
// 禁用远程调试
command_line->AppendSwitch("remote-debugging-port=0");
// 设置缓存目录
command_line->AppendSwitchWithValue("disk-cache-dir", "./cache");
// 设置User-Agent
command_line->AppendSwitchWithValue(
"user-agent",
"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 "
"Chrome/120.0.0.0 Safari/537.36"
);
}
IMPLEMENT_REFCOUNTING(SimpleApp);
};
class BrowserClient : public CefClient,
public CefLifeSpanHandler,
public CefLoadHandler {
public:
BrowserClient() : loading_complete_(false) {}
CefRefPtr<CefLifeSpanHandler> GetLifeSpanHandler() override { return this; }
CefRefPtr<CefLoadHandler> GetLoadHandler() override { return this; }
void OnAfterCreated(CefRefPtr<CefBrowser> browser) override {
browser_ = browser;
}
void OnLoadingStateChange(CefRefPtr<CefBrowser> browser,
bool isLoading,
bool canGoBack,
bool canGoForward) override {
if (!isLoading) {
loading_complete_ = true;
}
}
bool WaitForLoad(int timeout_seconds = 15) {
auto start = std::chrono::steady_clock::now();
while (!loading_complete_) {
auto elapsed = std::chrono::steady_clock::now() - start;
if (elapsed > std::chrono::seconds(timeout_seconds)) {
return false;
}
Sleep(100);
}
return true;
}
private:
CefRefPtr<CefBrowser> browser_;
bool loading_complete_;
IMPLEMENT_REFCOUNTING(BrowserClient);
};
int main(int argc, char* argv[]) {
CefMainArgs main_args(argc, argv);
CefRefPtr<SimpleApp> app(new SimpleApp());
CefSettings settings;
settings.no_sandbox = true;
settings.windowless_rendering_enabled = true;
CefInitialize(main_args, settings, app, nullptr);
CefWindowInfo window_info;
window_info.SetAsWindowless(0);
CefBrowserSettings browser_settings;
browser_settings.javascript = STATE_ENABLED;
browser_settings.image_loading = STATE_ENABLED;
CefRefPtr<BrowserClient> client(new BrowserClient());
CefBrowserHost::CreateBrowserSync(window_info, client,
"https://item.taobao.com/xxx.html", browser_settings, nullptr, nullptr);
CefRunMessageLoop();
CefShutdown();
return 0;
}
三、页面加载等待策略
3.1 等待控制器
class PageLoadController {
constructor(timeout = 15000) {
this.timeout = timeout;
this.startTime = Date.now();
}
async waitForReady() {
// 第一重：等待DOM就绪
while (document.readyState !== 'complete') {
await this.sleep(200);
if (this.isTimeout()) return false;
}
// 第二重：等待网络空闲
let idleCount = 0;
while (idleCount < 2) {
const activeRequests = performance.getEntriesByType('resource')
.filter(r => r.duration === 0).length;
if (activeRequests === 0) {
idleCount++;
} else {
idleCount = 0;
}
await this.sleep(500);
if (this.isTimeout()) return false;
}
// 第三重：等待jQuery（部分平台依赖）
while (typeof jQuery === 'undefined') {
await this.sleep(100);
if (this.isTimeout()) return false;
}
// 第四重：等待图片容器加载
let maxWait = 30;
while (maxWait-- > 0) {
const mainImg = document.querySelector('.main-image img, .J_mainImage, #imgTagWrapperId img');
if (mainImg && mainImg.src) {
break;
}
await this.sleep(500);
if (this.isTimeout()) return false;
}
// 第五重：触发懒加载
await this.triggerLazyLoad();
// 第六重：等待懒加载完成
await this.waitForLazyLoadComplete();
return true;
}
async triggerLazyLoad() {
window.scrollTo(0, document.body.scrollHeight);
await this.sleep(500);
const steps = [0.2, 0.4, 0.6, 0.8, 1.0];
for (const step of steps) {
window.scrollTo(0, document.body.scrollHeight * step);
await this.sleep(300);
}
window.scrollTo(0, 0);
await this.sleep(300);
}
async waitForLazyLoadComplete() {
let lastCount = 0;
let stableCount = 0;
while (stableCount < 3) {
const images = document.querySelectorAll('img[data-src], img[data-original]');
if (images.length === lastCount) {
stableCount++;
} else {
stableCount = 0;
lastCount = images.length;
}
await this.sleep(500);
if (this.isTimeout()) return false;
}
}
sleep(ms) {
return new Promise(resolve => setTimeout(resolve, ms));
}
isTimeout() {
return Date.now() - this.startTime > this.timeout;
}
}
四、DOM解析与素材提取
4.1 通用DOM提取器
class UniversalDOMExtractor {
constructor() {
this.result = {
title: '',
images: [],
videos: []
};
this.seenUrls = new Set();
}
extract() {
this.result.title = this.extractTitle();
this.result.images = this.extractAllImages();
this.result.videos = this.extractAllVideos();
return this.result;
}
extractTitle() {
const selectors = ['.product-title', '.sku-name', '.goods-name', 'h1', 'title'];
for (const selector of selectors) {
const el = document.querySelector(selector);
if (el && el.textContent) {
let title = el.textContent.trim();
if (title.length > 3 && title.length < 500) return title;
}
}
return document.title || '未命名商品';
}
extractAllImages() {
const images = [];
document.querySelectorAll('img').forEach(img => {
let url = img.src || img.getAttribute('data-src') || img.getAttribute('data-original');
if (!url) return;
if (this.seenUrls.has(url)) return;
this.seenUrls.add(url);
images.push({
url: url,
width: img.naturalWidth || img.width || 0,
height: img.naturalHeight || img.height || 0,
alt: img.alt || '',
parentClass: img.parentElement?.className || '',
parentId: img.parentElement?.id || ''
});
});
return images;
}
extractAllVideos() {
const videos = [];
document.querySelectorAll('video').forEach(video => {
let url = video.src;
if (!url) {
const source = video.querySelector('source');
if (source) url = source.src;
}
if (url && !this.seenUrls.has(url)) {
this.seenUrls.add(url);
videos.push({ url: url, type: url.endsWith('.mp4') ? 'mp4' : 'm3u8' });
}
});
return videos;
}
}
五、图片URL原图转换
5.1 各平台转换规则
class ImageUrlConverter {
static toOriginal(url, platform) {
if (!url) return null;
if (url.startsWith('data:')) return null;
if (url.includes('1x1') || url.includes('blank.gif')) return null;
url = url.split('?')[0];
switch(platform) {
case 'taobao':
case 'tmall':
url = url.replace(/_\d+x\d+\./g, '.');
url = url.replace(/\.sum\./g, '.');
break;
case 'jd':
url = url.replace(/\/n\d\//, '/n0/');
url = url.replace(/\/popWaterMark\//, '/');
break;
case 'pdd':
url = url.replace(/_\d+x\d+\./g, '.');
url = url.replace(/\.webp$/i, '.jpg');
break;
case '1688':
url = url.replace(/_\d+x\d+\./g, '.');
break;
case 'amazon':
url = url.replace(/\._[A-Z]+_\d+_\./g, '.');
url = url.replace(/\._SR\d+_\d+_\./g, '.');
break;
default:
url = url.replace(/_\d+x\d+\./g, '.');
}
return url;
}
}
5.2 原图获取示例
// 淘宝示例
const taobaoUrl = 'https://img.alicdn.com/xxx_100x100.jpg';
const original = ImageUrlConverter.toOriginal(taobaoUrl, 'taobao');
// 结果: https://img.alicdn.com/xxx.jpg
// 京东示例
const jdUrl = 'https://img13.360buyimg.com/n1/xxx.jpg';
const original = ImageUrlConverter.toOriginal(jdUrl, 'jd');
// 结果: https://img13.360buyimg.com/n0/xxx.jpg
// 亚马逊示例
const amazonUrl = 'https://images-na.ssl-images-amazon.com/images/I/71xxx._AC_SL1500_.jpg';
const original = ImageUrlConverter.toOriginal(amazonUrl, 'amazon');
// 结果: https://images-na.ssl-images-amazon.com/images/I/71xxx.jpg
六、SKU图自动分类
6.1 SKU分类器
class SKUClassifier {
constructor() {
this.skuContainers = [
'.tb-sku', '.J_sku', // 淘宝/天猫
'.sku-img-list', '.J_skuImgList', // 京东
'.sku-list', '.J_skuList', // 拼多多
'.sku-list', '.attribute-list' // 1688
];
this.skuItemSelectors = ['.sku-item', '.J_skuItem', '.sku-img-item', '.attribute-item'];
this.nameSelectors = ['.sku-name', '.J_skuName', '.tb-sku-name', '.attr-name'];
}
async extract() {
const container = this.findContainer();
if (!container) return [];
const items = this.findItems(container);
const skuList = [];
for (const item of items) {
const sku = this.parseItem(item);
if (sku && sku.url) skuList.push(sku);
}
return this.deduplicate(skuList);
}
findContainer() {
for (const selector of this.skuContainers) {
const container = document.querySelector(selector);
if (container && container.querySelectorAll('img').length > 0) return container;
}
return null;
}
findItems(container) {
for (const selector of this.skuItemSelectors) {
const items = container.querySelectorAll(selector);
if (items.length > 0) return items;
}
return [];
}
parseItem(item) {
const name = this.extractName(item);
const url = this.extractImage(item);
return { name, url };
}
extractName(item) {
for (const selector of this.nameSelectors) {
const el = item.querySelector(selector);
if (el) {
const name = el.textContent?.trim();
if (name && name.length < 30) return name;
}
}
const dataValue = item.getAttribute('data-value');
if (dataValue) return dataValue;
const title = item.getAttribute('title');
if (title) return title;
return '规格';
}
extractImage(item) {
const img = item.querySelector('img');
if (!img) return null;
let url = img.src || img.getAttribute('data-src');
if (!url) return null;
return ImageUrlConverter.toOriginal(url);
}
deduplicate(list) {
const map = new Map();
for (const item of list) {
if (!map.has(item.name)) map.set(item.name, item);
}
return Array.from(map.values());
}
}
七、视频下载与m3u8合并
7.1 视频提取器
class VideoExtractor {
extract() {
const video = document.querySelector('video');
if (video && video.src) {
return { url: video.src, type: video.src.endsWith('.mp4') ? 'mp4' : 'm3u8' };
}
const source = document.querySelector('video source');
if (source && source.src) {
return { url: source.src, type: source.src.endsWith('.mp4') ? 'mp4' : 'm3u8' };
}
const html = document.documentElement.innerHTML;
const patterns = [
/videoUrl["']?\s*[=:]\s*["']([^"']+\.(?:mp4|m3u8))["']/i,
/video_url["']?\s*[=:]\s*["']([^"']+\.(?:mp4|m3u8))["']/i,
/"url"\s*:\s*"([^"]+\.(?:mp4|m3u8))"/i
];
for (const pattern of patterns) {
const match = html.match(pattern);
if (match) return { url: match[1], type: match[1].endsWith('.mp4') ? 'mp4' : 'm3u8' };
}
return null;
}
}
7.2 m3u8下载器
import os, time, requests, m3u8
from concurrent.futures import ThreadPoolExecutor
class M3U8Downloader:
def __init__(self, max_workers=10):
self.max_workers = max_workers
self.headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36'}
def download(self, m3u8_url, output_path):
playlist = m3u8.load(m3u8_url, headers=self.headers)
base_url = '/'.join(m3u8_url.split('/')[:-1]) + '/'
segments = [seg.uri if seg.uri.startswith('http') else base_url + seg.uri for seg in playlist.segments]
print(f"发现 {len(segments)} 个ts片段")
temp_dir = f"temp_{int(time.time())}"
os.makedirs(temp_dir, exist_ok=True)
ts_files = []
with ThreadPoolExecutor(max_workers=self.max_workers) as executor:
futures = []
for i, ts_url in enumerate(segments):
ts_path = os.path.join(temp_dir, f"seg_{i:05d}.ts")
futures.append(executor.submit(self._download_ts, ts_url, ts_path))
ts_files.append(ts_path)
for future in futures: future.result()
os.makedirs(os.path.dirname(output_path), exist_ok=True)
with open(output_path, 'wb') as outfile:
for ts_file in ts_files:
if os.path.exists(ts_file):
with open(ts_file, 'rb') as infile:
outfile.write(infile.read())
for ts_file in ts_files:
if os.path.exists(ts_file): os.remove(ts_file)
os.rmdir(temp_dir)
return True
def _download_ts(self, url, path, retry=3):
for attempt in range(retry):
try:
response = requests.get(url, headers=self.headers, timeout=30)
if response.status_code == 200:
with open(path, 'wb') as f: f.write(response.content)
return True
except:
if attempt < retry - 1: time.sleep(1)
return False
八、智能分类算法
class ImageClassifier {
constructor() {
this.categories = { main: [], sku: [], detail: [] };
}
classify(images) {
images.forEach(img => {
const score = this.calculateScore(img);
const category = this.getCategory(score);
this.categories[category].push(img);
});
return this.categories;
}
calculateScore(img) {
const score = { main: 0, sku: 0, detail: 0 };
if (img.width >= 400) score.main += 2;
else if (img.width <= 150) score.sku += 2;
else score.detail += 1;
const parentClass = img.parentClass.toLowerCase();
if (parentClass.includes('carousel') || parentClass.includes('thumb')) score.main += 3;
if (parentClass.includes('sku')) score.sku += 3;
if (parentClass.includes('description') || parentClass.includes('detail')) score.detail += 2;
const alt = img.alt.toLowerCase();
if (alt.includes('main') || alt.includes('主图')) score.main += 1;
if (alt.includes('color') || alt.includes('size') || alt.includes('颜色') || alt.includes('尺码')) score.sku += 1;
return score;
}
getCategory(score) {
if (score.main >= score.sku && score.main >= score.detail) return 'main';
if (score.sku >= score.main && score.sku >= score.detail) return 'sku';
return 'detail';
}
}
九、文件存储与归档
class StorageManager {
constructor(basePath = './downloads') { this.basePath = basePath; }
saveProduct(data) {
const safeTitle = this.sanitizeFilename(data.title);
const productPath = `${this.basePath}/${safeTitle}`;
['视频', '主图', 'SKU图', '详情图'].forEach(dir => this.ensureDir(`${productPath}/${dir}`));
const result = { main: [], sku: [], detail: [], video: [] };
data.mainImages.forEach((url, i) => result.main.push({ url, path: `${productPath}/主图/主图_${i+1}.jpg` }));
data.skuImages.forEach(sku => result.sku.push({ url: sku.url, path: `${productPath}/SKU图/${this.sanitizeFilename(sku.name)}.jpg`, name: sku.name }));
data.detailImages.forEach((url, i) => result.detail.push({ url, path: `${productPath}/详情图/详情图_${i+1}.jpg` }));
if (data.video) result.video.push({ url: data.video.url, path: `${productPath}/视频/视频.mp4` });
return result;
}
sanitizeFilename(name) { return name.replace(/[\\/*?:"<>|]/g, '_').substring(0, 200); }
ensureDir(path) {}
}
十、批量采集与队列管理
class TaskQueue {
constructor(concurrency = 1) {
this.concurrency = concurrency;
this.queue = [];
this.running = 0;
this.results = [];
}
add(task) {
return new Promise((resolve, reject) => {
this.queue.push({ task, resolve, reject });
this.process();
});
}
async process() {
if (this.running >= this.concurrency || this.queue.length === 0) return;
this.running++;
const { task, resolve, reject } = this.queue.shift();
try {
const result = await task();
this.results.push(result);
resolve(result);
} catch (error) { reject(error);
} finally { this.running--; this.process(); }
}
async addAll(tasks) { return Promise.all(tasks.map(task => this.add(task))); }
}
十一、断点续传实现
class ResumeManager {
constructor(stateFile = 'batch_state.json') {
this.stateFile = stateFile;
this.completed = new Set();
this.load();
}
load() {
try {
const data = localStorage.getItem(this.stateFile);
if (data) {
const parsed = JSON.parse(data);
this.completed = new Set(parsed.completed || []);
console.log(`加载断点: 已完成 ${this.completed.size} 个商品`);
}
} catch(e) {}
}
save() {
const data = { completed: Array.from(this.completed), lastUpdate: new Date().toISOString() };
localStorage.setItem(this.stateFile, JSON.stringify(data));
}
isCompleted(id) { return this.completed.has(id); }
markCompleted(id) { this.completed.add(id); this.save(); }
}
十二、性能优化策略
class MemoryOptimizer {
static release() {
if (typeof window !== 'undefined') window.gc && window.gc();
if (window.performance && window.performance.clearResourceTimings) window.performance.clearResourceTimings();
}
}
class NetworkOptimizer {
static async downloadWithRetry(url, retries = 3) {
for (let i = 0; i < retries; i++) {
try {
const response = await fetch(url);
if (response.ok) return await response.blob();
} catch(e) {
if (i === retries - 1) throw e;
await this.sleep(1000 * (i + 1));
}
}
}
static sleep(ms) { return new Promise(resolve => setTimeout(resolve, ms)); }
}
十三、各平台适配差异
| 平台 | 主图容器 | SKU容器 | 视频格式 | 特殊处理 |
|---|---|---|---|---|
| 淘宝 | .J_UlThumb | .tb-sku | mp4/m3u8 | 尺寸后缀去除 |
| 京东 | .spec-img | .sku-img-list | mp4/m3u8 | n1→n0转换 |
| 拼多多 | .main-image | .sku-list | mp4 | webp转jpg |
| 1688 | .main-image | .sku-list | 不支持 | 需登录 |
| 亚马逊 | #imgTagWrapperId | .variation-selector | mp4 | 尺寸参数去除 |
十四、完整代码集成
class ProductCollector {
constructor() {
this.loader = new PageLoadController();
this.extractor = new UniversalDOMExtractor();
this.classifier = new ImageClassifier();
this.converter = ImageUrlConverter;
this.storage = new StorageManager();
this.resume = new ResumeManager();
}
async collect(url, productId) {
if (this.resume.isCompleted(productId)) return { skipped: true };
try {
await this.loader.waitForReady();
const data = this.extractor.extract();
const originalImages = data.images.map(img => ({ ...img, url: this.converter.toOriginal(img.url) }));
const classified = this.classifier.classify(originalImages);
const skuExtractor = new SKUClassifier();
const skuImages = await skuExtractor.extract();
const videoExtractor = new VideoExtractor();
const video = videoExtractor.extract();
const saved = this.storage.saveProduct({
title: data.title,
mainImages: classified.main.map(img => img.url),
skuImages: skuImages,
detailImages: classified.detail.map(img => img.url),
video: video
});
this.resume.markCompleted(productId);
return { success: true, data: saved };
} catch (error) {
return { success: false, error: error.message };
}
}
}
async function main() {
const collector = new ProductCollector();
const urls = ['https://item.taobao.com/xxx.html', 'https://item.jd.com/xxx.html'];
const batchCollector = new TaskQueue(1);
const promises = urls.map(url => () => collector.collect(url));
const results = await batchCollector.addAll(promises);
console.log(`成功: ${results.filter(r => r.success).length}, 失败: ${results.filter(r => !r.success).length}`);
}
