1688商品详情API接口实战指南：合规获取数据，驱动B2B业务增长

import requests
import hashlib
import time
import urllib.parse
# 配置信息（替换为你的实际参数）
APP_KEY = "你的appkey"
APP_SECRET = "你的secret"
PRODUCT_ID = "694567890123"  # 1688商品ID
API_URL = "https://gw.open.1688.com/openapi/param2/1/com.alibaba.product/alibaba.product.get"
# 1. 组装参数
params = {
    "app_key": APP_KEY,
    "method": "alibaba.product.get",
    "timestamp": time.strftime("%Y-%m-%d %H:%M:%S"),
    "v": "1.0",
    "format": "json",
    "productId": PRODUCT_ID,
    # 按需指定返回字段，避免冗余数据
    "fields": "productId,title,priceRange,moq,stock,imageUrls,seller,shipping"
}
# 2. 生成签名
sorted_params = sorted(params.items(), key=lambda x: x[0])  # 按参数名排序
# URL编码参数值，拼接为字符串
sign_str = "&".join([f"{k}={urllib.parse.quote_plus(v)}" for k, v in sorted_params])
# 加密生成签名
sign = hashlib.md5((sign_str + "&secret=" + APP_SECRET).encode()).hexdigest().upper()
params["sign"] = sign
# 3. 发送请求并解析数据
response = requests.get(API_URL, params=params)
result = response.json()
# 4. 处理响应
if result.get("success"):
    product = result["result"]["product"]
    print("=== 1688商品详情 ===")
    print(f"商品标题：{product['title']}")
    print(f"价格范围：{product['priceRange']['minPrice']}-{product['priceRange']['maxPrice']}元")
    print(f"起订量：{product['moq']}件")
    print(f"当前库存：{product['stock']}件")
    print(f"供应商：{product['seller']['sellerName']}（诚信通{product['seller']['memberLevel']}年）")
    print(f"是否支持混批：{'是' if product['shipping']['supportMix'] else '否'}")
else:
    print(f"调用失败：{result['errorMessage']}（错误码：{result['errorCode']}）")
