# Flask

> 使用 Firecrawl 和 Flask 在 Python 中构建网页抓取和搜索 API。

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

* Python 3.8+
* Firecrawl API 密钥 — [免费获取](https://www.firecrawl.dev/app/api-keys)

<div id="setup">
  ## 设置
</div>

```bash theme={null}
pip install flask firecrawl-py
```

将你的 API 密钥添加到 `.env` 中：

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

<div id="create-the-app">
  ## 创建应用程序
</div>

创建 `app.py`：

```python theme={null}
import os
from flask import Flask, request, jsonify
from firecrawl import Firecrawl

app = Flask(__name__)
firecrawl = Firecrawl(api_key=os.environ["FIRECRAWL_API_KEY"])


@app.post("/search")
def search():
    data = request.get_json()
    results = firecrawl.search(data["query"], limit=data.get("limit", 5))
    return jsonify([{"title": r.title, "url": r.url} for r in results.web])


@app.post("/scrape")
def scrape():
    data = request.get_json()
    result = firecrawl.scrape(data["url"])
    return jsonify(markdown=result.markdown, metadata=result.metadata)


@app.post("/interact/start")
def interact_start():
    data = request.get_json()
    result = firecrawl.scrape(data["url"], formats=["markdown"])
    return jsonify(scrape_id=result.metadata.scrape_id)


@app.post("/interact")
def interact():
    data = request.get_json()
    response = firecrawl.interact(data["scrape_id"], prompt=data["prompt"])
    return jsonify(output=response.output)


@app.post("/interact/stop")
def interact_stop():
    data = request.get_json()
    firecrawl.stop_interaction(data["scrape_id"])
    return jsonify(status="stopped")


if __name__ == "__main__":
    app.run(debug=True)
```

<div id="run-it">
  ## 运行
</div>

```bash theme={null}
flask run
```

<div id="test-it">
  ## 试一试
</div>

```bash theme={null}
# 进行网页搜索
curl -X POST http://localhost:5000/search \
  -H "Content-Type: application/json" \
  -d '{"query": "firecrawl web scraping", "limit": 5}'

# 抓取页面
curl -X POST http://localhost:5000/scrape \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com"}'

# 启动交互式会话
curl -X POST http://localhost:5000/interact/start \
  -H "Content-Type: application/json" \
  -d '{"url": "https://www.amazon.com"}'
```
