# Go

> 在 Go 中开始使用 Firecrawl。通过 REST API 抓取、搜索并与网页数据交互。

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

* Go 1.21+
* Firecrawl API 密钥 — [免费获取](https://www.firecrawl.dev/app/api-keys)

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

Firecrawl 可通过 REST API 与 Go 集成使用。使用 `net/http` 直接发起请求。

```go theme={null}
package main

import (
	"bytes"
	"encoding/json"
	"fmt"
	"io"
	"net/http"
	"os"
)

func main() {
	apiKey := os.Getenv("FIRECRAWL_API_KEY")

	body, _ := json.Marshal(map[string]interface{}{
		"query": "firecrawl web scraping",
		"limit": 5,
	})

	req, _ := http.NewRequest("POST", "https://api.firecrawl.dev/v2/search", bytes.NewReader(body))
	req.Header.Set("Authorization", "Bearer "+apiKey)
	req.Header.Set("Content-Type", "application/json")

	resp, err := http.DefaultClient.Do(req)
	if err != nil {
		fmt.Fprintf(os.Stderr, "请求失败: %v\n", err)
		os.Exit(1)
	}
	defer resp.Body.Close()

	result, _ := io.ReadAll(resp.Body)
	fmt.Println(string(result))
}
```

<Accordion title="示例响应">
  ```json theme={null}
  {
    "success": true,
    "data": {
      "web": [
        {
          "url": "https://docs.firecrawl.dev",
          "title": "Firecrawl Documentation",
          "markdown": "# Firecrawl\n\nFirecrawl is a web scraping API..."
        }
      ]
    }
  }
  ```
</Accordion>

<div id="scrape-a-page">
  ## 抓取网页

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

启动浏览器会话，使用自然语言 prompt 与页面交互，然后关闭会话。

<div id="step-1-scrape-to-start-a-session">
  ### 第 1 步 — 先抓取页面以开启会话
</div>

```go theme={null}
body, _ := json.Marshal(map[string]interface{}{
	"url":     "https://www.amazon.com",
	"formats": []string{"markdown"},
})

req, _ := http.NewRequest("POST", "https://api.firecrawl.dev/v2/scrape", bytes.NewReader(body))
req.Header.Set("Authorization", "Bearer "+apiKey)
req.Header.Set("Content-Type", "application/json")

resp, err := http.DefaultClient.Do(req)
if err != nil {
	fmt.Fprintf(os.Stderr, "request failed: %v\n", err)
	os.Exit(1)
}
defer resp.Body.Close()

var scrapeResult map[string]interface{}
json.NewDecoder(resp.Body).Decode(&scrapeResult)

data := scrapeResult["data"].(map[string]interface{})
metadata := data["metadata"].(map[string]interface{})
scrapeId := metadata["scrapeId"].(string)
fmt.Println("scrapeId:", scrapeId)
```

<div id="step-2-send-interactions">
  ### 第 2 步 — 发送交互操作
</div>

```go theme={null}
// 搜索产品
interactBody, _ := json.Marshal(map[string]string{
	"prompt": "Search for iPhone 16 Pro Max",
})

interactURL := fmt.Sprintf("https://api.firecrawl.dev/v2/scrape/%s/interact", scrapeId)
req, _ = http.NewRequest("POST", interactURL, bytes.NewReader(interactBody))
req.Header.Set("Authorization", "Bearer "+apiKey)
req.Header.Set("Content-Type", "application/json")

resp, err = http.DefaultClient.Do(req)
if err != nil {
	fmt.Fprintf(os.Stderr, "interact failed: %v\n", err)
	os.Exit(1)
}
defer resp.Body.Close()

result, _ := io.ReadAll(resp.Body)
fmt.Println(string(result))

// 点击第一个结果
interactBody, _ = json.Marshal(map[string]string{
	"prompt": "Click on the first result and tell me the price",
})

req, _ = http.NewRequest("POST", interactURL, bytes.NewReader(interactBody))
req.Header.Set("Authorization", "Bearer "+apiKey)
req.Header.Set("Content-Type", "application/json")

resp, err = http.DefaultClient.Do(req)
if err != nil {
	fmt.Fprintf(os.Stderr, "interact failed: %v\n", err)
	os.Exit(1)
}
defer resp.Body.Close()

result, _ = io.ReadAll(resp.Body)
fmt.Println(string(result))
```

<div id="step-3-stop-the-session">
  ### 步骤 3 — 结束会话
</div>

```go theme={null}
req, _ = http.NewRequest("DELETE", interactURL, nil)
req.Header.Set("Authorization", "Bearer "+apiKey)

resp, err = http.DefaultClient.Do(req)
if err != nil {
	fmt.Fprintf(os.Stderr, "删除失败: %v\n", err)
	os.Exit(1)
}
defer resp.Body.Close()

fmt.Println("会话已停止")
```

<div id="reusable-helper">
  ## 可复用的辅助函数
</div>

如果需要重复使用，可将 API 封装成一个简单的辅助函数：

```go theme={null}
type FirecrawlClient struct {
	APIKey  string
	BaseURL string
	Client  *http.Client
}

func NewFirecrawlClient(apiKey string) *FirecrawlClient {
	return &FirecrawlClient{
		APIKey:  apiKey,
		BaseURL: "https://api.firecrawl.dev/v2",
		Client:  &http.Client{},
	}
}

func (fc *FirecrawlClient) post(endpoint string, payload interface{}) ([]byte, error) {
	body, err := json.Marshal(payload)
	if err != nil {
		return nil, err
	}

	req, err := http.NewRequest("POST", fc.BaseURL+endpoint, bytes.NewReader(body))
	if err != nil {
		return nil, err
	}
	req.Header.Set("Authorization", "Bearer "+fc.APIKey)
	req.Header.Set("Content-Type", "application/json")

	resp, err := fc.Client.Do(req)
	if err != nil {
		return nil, err
	}
	defer resp.Body.Close()

	return io.ReadAll(resp.Body)
}

func (fc *FirecrawlClient) Scrape(url string) ([]byte, error) {
	return fc.post("/scrape", map[string]string{"url": url})
}

func (fc *FirecrawlClient) Search(query string, limit int) ([]byte, error) {
	return fc.post("/search", map[string]interface{}{"query": query, "limit": limit})
}
```
