OpenClaw + LLM 电商平台集成指南

📦 依赖安装

# 基础依赖
pip install openclaw-python-sdk
pip install langchain
pip install openai  # 或 anthropic, cohere

# 向量数据库（选一个）
pip install pinecone-client
# 或
pip install qdrant-client
# 或
pip install chromadb

# 数据处理
pip install pandas numpy
pip install faiss-cpu  # 或 faiss-gpu

🗄️ 数据准备

1. 商品数据向量化

from langchain.embeddings import OpenAIEmbeddings
from langchain.vectorstores import Pinecone

# 准备商品数据
products = [
    {
        "id": "p001",
        "name": "Apple iPhone 15 Pro",
        "description": "A17 Pro芯片,钛金属设计,48MP相机",
        "price": 8999,
        "category": "手机"
    },
    # ... 更多商品
]

# 生成向量 embeddings
embeddings = OpenAIEmbeddings()
vectorstore = Pinecone.from_documents(
    documents=[text_to_doc(p) for p in products],
    embedding=embeddings,
    index_name="ecommerce-products"
)

2. 构建知识库

knowledge_base = {
    "faq": [
        "Q: 如何退换货？\nA: 支持7天无理由退换货...",
        "Q: 物流多久能到？\nA: 大部分地区2-3天..."
    ],
    "policies": [
        "退款政策: ...",
        "隐私政策: ..."
    ],
    "product_details": products
}

🤖 OpenClaw Agent 配置

基础配置

from openclaw import Agent

# 创建电商智能客服 Agent
ecommerce_agent = Agent(
    name="电商智能助手",
    instructions="""
    你是一个专业的电商智能客服助手，负责：
    1. 回答用户关于商品、订单、物流的问题
    2. 根据用户需求推荐合适商品
    3. 处理售后问题和投诉
    4. 引导用户完成购买流程

    重要规则：
    - 始终基于真实商品数据回答
    - 推荐时要考虑用户历史偏好
    - 遇到无法确定的问题，引导用户联系人工客服
    - 保持友好、专业的语气
    """,
    tools=[search_products, get_order_status, recommend_products],
    model="gpt-4",  # 或其他 LLM
)

🔌 工具函数实现

工具1：商品搜索

📈 优化策略

1. 缓存优化

from functools import lru_cache
from redis import Redis

redis_client = Redis()

@lru_cache(maxsize=1000)
def get_product_info(product_id: str):
    """商品信息缓存"""
    # 先查 Redis
    cached = redis_client.get(f"product:{product_id}")
    if cached:
        return json.loads(cached)

    # 查数据库
    product = db.query_product(product_id)

    # 写入缓存
    redis_client.setex(
        f"product:{product_id}",
        3600,  # 1小时过期
        json.dumps(product)
    )

    return product

2. 异步处理

import asyncio
from concurrent.futures import ThreadPoolExecutor

executor = ThreadPoolExecutor(max_workers=10)

async def batch_recommend(users: List[str]):
    """批量异步推荐"""
    tasks = [
        asyncio.get_event_loop().run_in_executor(
            executor,
            recommend_products,
            user_id
        )
        for user_id in users
    ]
    results = await asyncio.gather(*tasks)
    return results

3. 成本优化

# 使用较小的模型处理简单请求
def route_request(message: str):
    """智能路由"""
    complexity = estimate_complexity(message)

    if complexity < 0.3:
        # 简单请求，使用小模型
        return gpt_3_5_turbo_model
    else:
        # 复杂请求，使用大模型
        return gpt_4_model

# 缓存常见问题的答案
COMMON_QUESTIONS_CACHE = {
    "退货流程": "支持7天无理由退换货...",
    "物流时间": "大部分地区2-3天...",
}

def get_answer(message: str):
    """优先使用缓存"""
    for question, answer in COMMON_QUESTIONS_CACHE.items():
        if question in message:
            return answer
    return call_llm(message)

⚠️ 注意事项

1. 数据安全

• 加密存储用户对话
• 遵守 GDPR/隐私法规
• 定期审计数据访问日志

2. 性能优化

• 目标响应时间 < 2秒
• 使用 CDN 加速静态资源
• 实施负载均衡

3. 成本控制

• 监控 API 调用量
• 使用缓存减少重复请求
• 考虑使用本地模型降低成本

4. 持续优化

• A/B 测试不同 prompt
• 收集用户反馈改进
• 定期重新训练推荐模型
