Hono

使用 Firecrawl 与 Hono 构建可在任何环境中运行的轻量级网页抓取和搜索 API。

​

前提条件

• Node.js 18+、Bun 或 Deno
• Firecrawl API 密钥 — 免费获取

​

配置

npm install hono firecrawl

将你的 API 密钥添加到 .env 文件中：

FIRECRAWL_API_KEY=fc-YOUR-API-KEY

​

进行网页搜索

import { Hono } from "hono";
import { Firecrawl } from "firecrawl";

const app = new Hono();
const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });

app.post("/search", async (c) => {
  const { query } = await c.req.json();
  const results = await firecrawl.search(query, { limit: 5 });
  return c.json(results);
});

export default app;

​

抓取网页

app.post("/scrape", async (c) => {
  const { url } = await c.req.json();
  const result = await firecrawl.scrape(url);
  return c.json(result);
});

​

与页面交互

使用 interact 控制实时浏览器会话，可点击按钮、填写表单并提取动态内容。

app.post("/interact", async (c) => {
  const { url } = await c.req.json();

  const result = await firecrawl.scrape(url, { formats: ['markdown'] });
  const scrapeId = result.metadata?.scrapeId;

  await firecrawl.interact(scrapeId, { prompt: 'Search for iPhone 16 Pro Max' });
  const response = await firecrawl.interact(scrapeId, { prompt: 'Click on the first result and tell me the price' });

  await firecrawl.stopInteraction(scrapeId);

  return c.json({ output: response.output });
});

​

可部署到任意环境

Hono 支持在多种运行时中运行。对于 Cloudflare Workers，请通过环境绑定传入 API 密钥：

import { Hono } from "hono";
import { Firecrawl } from "firecrawl";

type Bindings = { FIRECRAWL_API_KEY: string };
const app = new Hono<{ Bindings: Bindings }>();

app.post("/search", async (c) => {
  const firecrawl = new Firecrawl({ apiKey: c.env.FIRECRAWL_API_KEY });
  const { query } = await c.req.json();
  const results = await firecrawl.search(query, { limit: 5 });
  return c.json(results);
});

export default app;
