了解如何高效抓取 Wikipedia，用于研究、知识抽取与构建 AI 应用。

​
安装与配置

npm install @mendable/firecrawl-js zod

​
适用场景

  • 研究自动化与事实核查
  • 构建知识图谱
  • 多语言内容提取
  • 教育内容聚合
  • 实体信息提取

​
使用 JSON 模式进行抓取

使用 Zod 模式从 Wikipedia 条目中提取结构化数据。 
import FirecrawlApp from '@mendable/firecrawl-js';
import { z } from 'zod';

const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY });

const result = await firecrawl.scrape('https://en.wikipedia.org/wiki/JavaScript', {
    formats: [{
        type: 'json',
        schema: z.object({
            name: z.string(),
            creator: z.string(),
            firstAppeared: z.string(),
            typingDiscipline: z.string(),
            website: z.string()
        })
    }]
});

console.log(result.json);
在 Wikipedia 上搜索文章。 
import FirecrawlApp from '@mendable/firecrawl-js';

const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY });

const searchResult = await firecrawl.search('quantum computing site:en.wikipedia.org', {
    limit: 10,
    sources: [{ type: 'web' }], // { type: 'news' }、{ type: 'images' }
    scrapeOptions: {
        formats: ['markdown']
    }
});

console.log(searchResult);

​
抓取

抓取一篇维基百科文章。 
import FirecrawlApp from '@mendable/firecrawl-js';

const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY });

const result = await firecrawl.scrape('https://en.wikipedia.org/wiki/Artificial_intelligence', {
    formats: ['markdown'], // 例如 html、links 等
    onlyMainContent: true
});

console.log(result);

​
Map

在 Wikipedia 的门户或分类中发现所有可用的 URL。注意：Map 仅返回 URL，不包含内容。 
import FirecrawlApp from '@mendable/firecrawl-js';

const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY });

const mapResult = await firecrawl.map('https://en.wikipedia.org/wiki/Portal:Computer_science');

console.log(mapResult.links);
// 返回不含内容的 URL 数组

​
爬取

从 Wikipedia 的文档或分类中爬取多个页面。 
import FirecrawlApp from '@mendable/firecrawl-js';

const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY });

const crawlResult = await firecrawl.crawl('https://en.wikipedia.org/wiki/Portal:Artificial_intelligence', {
    limit: 10,
    scrapeOptions: {
        formats: ['markdown']
    }
});

console.log(crawlResult.data);

​
批量抓取

同时抓取多个 Wikipedia 链接。 
import FirecrawlApp from '@mendable/firecrawl-js';

const firecrawl = new FirecrawlApp({ apiKey: process.env.FIRECRAWL_API_KEY });

// 等待完成
const job = await firecrawl.batchScrape([
    'https://en.wikipedia.org/wiki/Machine_learning',
    'https://en.wikipedia.org/wiki/Artificial_intelligence',
    'https://en.wikipedia.org/wiki/Deep_learning'],
    {
        options: {
            formats: ['markdown']
        },
        pollInterval: 2,
        timeout: 120
    }
);


console.log(job.status, job.completed, job.total);

console.log(job);
