## 前提条件 [#前提条件]
* Next.js 14+ 项目 (App Router)
* 一个 Firecrawl API 密钥 — [免费获取](https://www.firecrawl.dev/app/api-keys)
## 安装 SDK [#安装-sdk]
```bash
npm install firecrawl
```
## 设置 API 密钥 [#设置-api-密钥]
将 API 密钥添加到 `.env.local`：
```bash
FIRECRAWL_API_KEY=fc-YOUR-API-KEY
```
## 进行网页搜索 [#进行网页搜索]
该 SDK 只能在服务端运行，因为它需要你的 API 密钥。
### 路由处理程序 [#路由处理程序]
创建 `app/api/search/route.ts`：
```typescript
import { NextResponse } from "next/server";
import { Firecrawl } from "firecrawl";
const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });
export async function POST(request: Request) {
const { query } = await request.json();
const results = await firecrawl.search(query, { limit: 5 });
return NextResponse.json(results);
}
```
### 服务端操作 [#服务端操作]
创建 `app/actions.ts`，供客户端组件调用：
```typescript
"use server";
import { Firecrawl } from "firecrawl";
const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });
export async function searchWeb(query: string) {
const results = await firecrawl.search(query, { limit: 5 });
return (results.web || []).map((r) => ({ title: r.title, url: r.url }));
}
```
## 抓取页面 [#抓取页面]
### 路由处理程序 [#路由处理程序-1]
创建 `app/api/scrape/route.ts`：
```typescript
import { NextResponse } from "next/server";
import { Firecrawl } from "firecrawl";
const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });
export async function POST(request: Request) {
const { url } = await request.json();
const result = await firecrawl.scrape(url);
return NextResponse.json(result);
}
```
### 服务器组件 [#服务器组件]
在 `app/page.tsx` 的服务器组件中直接获取数据：
```tsx
import { Firecrawl } from "firecrawl";
const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });
export default async function Page() {
const result = await firecrawl.scrape("https://example.com");
return (
Scraped Content
{result.markdown}
);
}
```
## 与页面交互 [#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。
### 路由处理程序 [#路由处理程序-2]
创建 `app/api/interact/route.ts`：
```typescript
import { NextResponse } from "next/server";
import { Firecrawl } from "firecrawl";
const firecrawl = new Firecrawl({ apiKey: process.env.FIRECRAWL_API_KEY });
export async function POST(request: Request) {
const { url, prompts } = await request.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 NextResponse.json({ output: response.output });
}
```
## 下一步 [#下一步]
所有抓取选项，包括 formats、actions 和代理
进行网页搜索并获取完整页面内容
