python3 导出redis数据，根据redis前缀模糊匹配

# -*- coding: utf-8 -*-

import redis
import json

# 连接Redis
r = redis.Redis(
    host='you host ip addr',
    port=6379,
    password='you password',
    decode_responses=True
)

# 查询数据
pattern = 'test:cmsServer:article:*'
keys = r.keys(pattern)

# 导出数据
export_data = {}
for key in keys:
    value = r.get(key)
    export_data[key] = value

# 保存到文件
with open('redis_export.json', 'w', encoding='utf-8') as f:
    json.dump(export_data, f, ensure_ascii=False, indent=2)

print("导出完成，共{}条数据".format(len(keys)))
