Astro - Firecrawl Docs

前提条件#

已启用 SSR 的 Astro 项目 (output: "server" 或 "hybrid")
Firecrawl API 密钥——可免费获取

安装 SDK#

npm install 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#

新建 src/pages/api/search.ts：

import type { APIRoute } from "astro";import { Firecrawl } from "firecrawl";const firecrawl = new Firecrawl({  apiKey: import.meta.env.FIRECRAWL_API_KEY,});export const POST: APIRoute = async ({ request }) => {  const { query } = await request.json();  const results = await firecrawl.search(query, { limit: 5 });  return new Response(JSON.stringify(results), {    headers: { "Content-Type": "application/json" },  });};

或者在服务端渲染页面 (src/pages/search.astro) 中于请求时搜索：

---import { Firecrawl } from "firecrawl";const firecrawl = new Firecrawl({  apiKey: import.meta.env.FIRECRAWL_API_KEY,});const query = Astro.url.searchParams.get("q");let results = [];if (query) {  const searchData = await firecrawl.search(query, { limit: 5 });  results = searchData.web || [];}---<html>  <body>    <h1>搜索结果</h1>    {results.length > 0 ? (      <ul>        {results.map((r) => (          <li><a href={r.url}>{r.title}</a></li>        ))}      </ul>    ) : (      <p>传入 ?q= 进行网页搜索</p>    )}  </body></html>

抓取网页#

创建 src/pages/api/scrape.ts:

import type { APIRoute } from "astro";import { Firecrawl } from "firecrawl";const firecrawl = new Firecrawl({  apiKey: import.meta.env.FIRECRAWL_API_KEY,});export const POST: APIRoute = async ({ request }) => {  const { url } = await request.json();  const result = await firecrawl.scrape(url);  return new Response(JSON.stringify(result), {    headers: { "Content-Type": "application/json" },  });};

或者在服务端渲染页面中，在请求时进行抓取 (src/pages/scrape.astro) ：

---import { Firecrawl } from "firecrawl";const firecrawl = new Firecrawl({  apiKey: import.meta.env.FIRECRAWL_API_KEY,});const target = Astro.url.searchParams.get("url");let markdown = null;if (target) {  const result = await firecrawl.scrape(target);  markdown = result.markdown;}---<html>  <body>    <h1>Scraped Content</h1>    {markdown ? <pre>{markdown}</pre> : <p>Pass ?url= to scrape a page</p>}  </body></html>

与页面交互#

创建 src/pages/api/interact.ts：

import type { APIRoute } from "astro";import { Firecrawl } from "firecrawl";const firecrawl = new Firecrawl({  apiKey: import.meta.env.FIRECRAWL_API_KEY,});export const POST: APIRoute = async () => {  const result = await firecrawl.scrape("https://www.amazon.com", {    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 new Response(JSON.stringify({ output: response.output }), {    headers: { "Content-Type": "application/json" },  });};
