大模型無法直接擷取網頁資料。網頁抓取工具可以訪問指定 URL 並提取內容,為大模型提供所需資訊。
使用方式
網頁抓取功能支援三種調用方式,啟用參數有所不同:
OpenAI 相容-Responses API
要啟用網頁抓取功能,您需要在 tools 參數中同時添加 web_search(連網搜尋)和 web_extractor(網頁抓取)工具。
當使用 qwen3-max-2026-01-23 時,需要啟用 enable_thinking 參數以開啟思考模式。為獲得最佳回複效果,尤其是在解決數學計算、資料分析類問題時,建議同時開啟 code_interpreter 工具。這將允許模型在需要時調用代碼解譯器,提高結果的準確性。# 匯入依賴與建立用戶端...
response = client.responses.create(
model="qwen3-max-2026-01-23",
input="請訪問阿里雲百鍊代碼解譯器部分的官方文檔,並總結主要內容",
tools=[
# 開啟網頁抓取必須同時開啟連網搜尋工具
{"type": "web_search"},
{"type": "web_extractor"},
{"type": "code_interpreter"}
],
extra_body={
# 必須開啟思考模式
"enable_thinking": True
}
)
print(response.output_text)OpenAI 相容-Chat Completions API
通過 enable_search 參數啟用連網搜尋,並將 search_strategy 設定為 agent_max 以啟用網頁抓取功能。同時需要啟用 enable_thinking 參數開啟思考模式。
