Steam 工具包

Steam(维基百科)是由 Valve Corporation 开发的视频游戏数字发行服务和商店。它为 Valve 的游戏提供自动更新,并扩展到分发第三方游戏。Steam 提供各种功能,如带 Valve 反作弊措施的游戏服务器匹配、社交网络和游戏流媒体服务。

Steam 是玩游戏、讨论游戏和创建游戏的终极目的地。

Steam 工具包包含两个工具

  • 游戏详情
  • 推荐游戏

本笔记本提供了如何使用 LangChain 结合 Steam API 来根据您当前的 Steam 游戏库存检索 Steam 游戏推荐,或收集您提供的一些 Steam 游戏信息的演练。

设置

我们需要安装两个 Python 库。

导入

%pip install --upgrade --quiet python-steam-api python-decouple steamspypi
Note: you may need to restart the kernel to use updated packages.

分配环境变量

要使用此工具包,请准备好您的 OpenAI API 密钥、Steam API 密钥(从此处获取)和您自己的 SteamID。获得 Steam API 密钥后,您可以将其作为环境变量在下方输入。该工具包将把“STEAM_KEY”API 密钥作为环境变量读取以进行身份验证,请在此处设置。您还需要设置您的“OPENAI_API_KEY”和您的“STEAM_ID”。

import os

os.environ["STEAM_KEY"] = ""
os.environ["STEAM_ID"] = ""
os.environ["OPENAI_API_KEY"] = ""

初始化:

初始化 LLM、SteamWebAPIWrapper、SteamToolkit,最重要的是初始化 langchain agent 以处理您的查询!

示例

from langchain_community.agent_toolkits.steam.toolkit import SteamToolkit
from langchain_community.utilities.steam import SteamWebAPIWrapper

steam = SteamWebAPIWrapper()
tools = [steam.run]
from langgraph.prebuilt import create_react_agent

agent = create_react_agent("openai:gpt-4.1-mini", tools)
API 参考:create_react_agent
events = agent.stream(
{"messages": [("user", "can you give the information about the game Terraria?")]},
stream_mode="values",
)
for event in events:
event["messages"][-1].pretty_print()
