## 准备工作 [#准备工作]
* Wrangler CLI (`npm install -g wrangler`)
* Firecrawl API 密钥——[免费获取](https://www.firecrawl.dev/app/api-keys)
## 设置 [#设置]
```bash
npm create cloudflare@latest my-scraper
cd my-scraper
npm install firecrawl
```
将你的 API 密钥添加为 Secret：
```bash
wrangler secret put FIRECRAWL_API_KEY
```
## 进行网页搜索 [#进行网页搜索]
创建一个处理函数，用于进行网页搜索，并返回包含完整页面内容的结果。
编辑 `src/index.ts`：
```typescript
import { Firecrawl } from "firecrawl";
export interface Env {
FIRECRAWL_API_KEY: string;
}
export default {
async fetch(request: Request, env: Env): Promise {
const firecrawl = new Firecrawl({ apiKey: env.FIRECRAWL_API_KEY });
const url = new URL(request.url);
if (request.method === "POST" && url.pathname === "/search") {
const { query } = (await request.json()) as { query: string };
const results = await firecrawl.search(query, { limit: 5 });
return Response.json(results);
}
return new Response("Not found", { status: 404 });
},
};
```
## 抓取网页 [#抓取网页]
添加一个 `/scrape` 路由，用于从任意 URL 提取干净的 Markdown。
```typescript
if (request.method === "POST" && url.pathname === "/scrape") {
const { url: targetUrl } = (await request.json()) as { url: string };
const result = await firecrawl.scrape(targetUrl);
return Response.json(result);
}
```
## 与页面交互 [#与页面交互]
添加 `/interact` 路由以控制实时浏览器会话——点击按钮、填写表单，并提取动态内容。
```typescript
if (request.method === "POST" && url.pathname === "/interact") {
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 Response.json({ output: response.output });
}
```
## 部署 [#部署]
```bash
wrangler deploy
```
## 试一试 [#试一试]
```bash
curl -X POST https://my-scraper..workers.dev/search \
-H "Content-Type: application/json" \
-d '{"query": "firecrawl web scraping"}'
```
