前提条件

  • Nuxt 3+ 项目
  • 一个 Firecrawl API 密钥 — 免费获取

​
安装 SDK

npm install @mendable/firecrawl-js
将 API 密钥添加到 .env 中： 
FIRECRAWL_API_KEY=fc-YOUR-API-KEY

​
进行网页搜索

创建 server/api/search.post.ts： 
import Firecrawl from "@mendable/firecrawl-js";

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

export default defineEventHandler(async (event) => {
  const { query } = await readBody(event);
  const results = await firecrawl.search(query, { limit: 5 });
  return results;
});
在 Vue 组件中这样调用： 
<script setup>
const query = ref("");
const { data, execute } = useFetch("/api/search", {
  method: "POST",
  body: { query },
  immediate: false,
});
</script>

<template>
  <div>
    <input v-model="query" placeholder="Search the web..." />
    <button @click="execute()">Search</button>
    <ul v-if="data?.web">
      <li v-for="result in data.web" :key="result.url">
        <a :href="result.url">{{ result.title }}</a>
      </li>
    </ul>
  </div>
</template>

​
抓取页面

创建 server/api/scrape.post.ts： 
import Firecrawl from "@mendable/firecrawl-js";

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

export default defineEventHandler(async (event) => {
  const { url } = await readBody(event);
  const result = await firecrawl.scrape(url);
  return result;
});
在 Vue 组件中调用： 
<script setup>
const url = ref("https://example.com");
const { data, execute } = useFetch("/api/scrape", {
  method: "POST",
  body: { url },
  immediate: false,
});
</script>

<template>
  <div>
    <input v-model="url" placeholder="Enter URL" />
    <button @click="execute()">Scrape</button>
    <pre v-if="data">{{ data.markdown }}</pre>
  </div>
</template>

​
与页面交互

创建 server/api/interact.post.ts： 
import Firecrawl from "@mendable/firecrawl-js";

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

export default defineEventHandler(async (event) => {
  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 { output: response.output };
});
