网硕互联帮助中心基于“关键词规则”分拣快递。根据物品描述匹配关键词，输出物流类别、推荐运输工具、温控要求和备注。规则可自行增删。

"活鸡",
"冷冻鸡腿",
"手机",
"锂电池",
"玻璃杯",
"重要文件",
"衣服"
]
for item in test_items:

print(json.dumps(result, ensure_ascii=False, indent=2))
print("-" * 50)
```
示例输出中的关键部分：
```json
{
"input": "鸡",
"matched_keywords": ["鸡"],
"category": "冷链运输",
"main_category": "冷链运输",
"transport": ["冷藏车", "冷链航空", "冷藏集装箱"],
"temperature": "冷冻-18°C；冷藏0-4°C",
"priority": 80,
"note": "全程温控记录"
}
```
如果输入的是“活鸡”，则会同时命中“活体运输”和“冷链运输”，但“活体运输”优先级更高，因此主类别会是活体运输。
实际物流中，活体、冷链、危险品、药品等通常有严格的资质和法规要求，这段代码适合做规则原型，生产环境建议接入承运商规则库、温控设备数据和人工审核流程。
