# Supabase Edge Functions

> 使用 Firecrawl 与 Supabase Edge Functions，在边缘搜索、抓取并与网页数据交互。

<div id="prerequisites">
  ## 前提条件
</div>

* 已使用 CLI 初始化 (`supabase init`) 的 Supabase 项目
* Firecrawl API 密钥——[免费获取一个](https://www.firecrawl.dev/app/api-keys)

<div id="setup">
  ## 配置
</div>

```bash theme={null}
supabase functions new firecrawl-search
supabase functions new firecrawl-scrape
supabase functions new firecrawl-interact
```

设置密钥：

```bash theme={null}
supabase secrets set FIRECRAWL_API_KEY=fc-YOUR-API-KEY
```

<div id="search-the-web">
  ## 进行网页搜索
</div>

编辑 `supabase/functions/firecrawl-search/index.ts`：

```typescript theme={null}
import Firecrawl from "npm:firecrawl";

const firecrawl = new Firecrawl({
  apiKey: Deno.env.get("FIRECRAWL_API_KEY"),
});

Deno.serve(async (req) => {
  const { query } = await req.json();
  const results = await firecrawl.search(query, { limit: 5 });

  return new Response(JSON.stringify(results), {
    headers: { "Content-Type": "application/json" },
  });
});
```

<div id="scrape-a-page">
  ## 抓取页面
</div>

编辑 `supabase/functions/firecrawl-scrape/index.ts`：

```typescript theme={null}
import Firecrawl from "npm:firecrawl";

const firecrawl = new Firecrawl({
  apiKey: Deno.env.get("FIRECRAWL_API_KEY"),
});

Deno.serve(async (req) => {
  const { url } = await req.json();
  const result = await firecrawl.scrape(url);

  return new Response(JSON.stringify(result), {
    headers: { "Content-Type": "application/json" },
  });
});
```

<div id="interact-with-a-page">
  ## 与页面进行交互
</div>

编辑 `supabase/functions/firecrawl-interact/index.ts`：

```typescript theme={null}
import Firecrawl from "npm:firecrawl";

const firecrawl = new Firecrawl({
  apiKey: Deno.env.get("FIRECRAWL_API_KEY"),
});

Deno.serve(async (_req) => {
  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",
  });
  console.log(response.output);

  await firecrawl.stopInteraction(scrapeId);

  return new Response(JSON.stringify({ output: response.output }), {
    headers: { "Content-Type": "application/json" },
  });
});
```

<div id="deploy">
  ## 部署
</div>

```bash theme={null}
supabase functions deploy firecrawl-search
supabase functions deploy firecrawl-scrape
supabase functions deploy firecrawl-interact
```

<div id="test-it">
  ## 试一试
</div>

```bash theme={null}
curl -X POST https://<project-ref>.supabase.co/functions/v1/firecrawl-search \
  -H "Authorization: Bearer <ANON_KEY>" \
  -H "Content-Type: application/json" \
  -d '{"query": "firecrawl web scraping"}'
```
