json配置文件读入redis - 包含命令行解析示例

需要的取用，也是笔记，python argv经常会需要解析。类linux的命令行参数处理，这也是一个示例。

1.源码

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
# 获取当前脚本文件所在目录的父目录，并构建相对路径
import os
import sys
import json
import redis
import argparse
current_dir = os.path.dirname(os.path.abspath(__file__))
project_path = os.path.join(current_dir, '..')
sys.path.append(project_path)
sys.path.append(current_dir)def load_json_from_file(file_path):# 打开文件并读取内容with open(file_path, 'r', encoding='utf-8') as file:json_str = file.read()# 将 JSON 字符串解析为 Python 对象data = json.loads(json_str)return datadef json2redis(data, root_name='cfg', redis_host='localhost', redis_port=6379):# 连接到 Redis 服务器r = redis.Redis(host='localhost', port=6379, decode_responses=True)# 定义一个递归函数来遍历数据并存储到 Redisdef store_in_redis(prefix, data):if isinstance(data, dict):for key, value in data.items():new_key = f"{prefix}:{key}"store_in_redis(new_key, value)elif isinstance(data, list):for index, item in enumerate(data):new_key = f"{prefix}:{index}"store_in_redis(new_key, item)else:r.set(prefix, data)# 调用函数，传入根键名store_in_redis(f"{root_name}", data)# 示例：从 Redis 获取存储的数据并打印for key in r.keys(f"{root_name}:*"):print(f"{key}: {r.get(key)}")def main():# 创建 ArgumentParser 对象parser = argparse.ArgumentParser(description='处理文件和选项')# 添加参数parser.add_argument('jsonfile', type=str, help='json_file_name')parser.add_argument('--redis_ip', type=str, default='127.0.0.1', help='redis server ip')parser.add_argument('--redis_port', type=int, default=6379, help='redis server port')parser.add_argument('--verbose', action='store_true', help='启用详细模式')# 解析命令行参数args = parser.parse_args()# 使用参数print(f'输入文件: {args.jsonfile}')print(f'输出文件: {args.redis_ip}')print(f'处理次数: {args.redis_port}')print(f'详细模式: {"启用" if args.verbose else "禁用"}')json_obj = load_json_from_file(args.jsonfile)filename_without_ext, _ = os.path.splitext(args.jsonfile)root = filename_without_extroot = root.replace("/", ":")root = root.replace("\\", ":")print(root)json2redis(json_obj, root, args.redis_ip, args.redis_port)if __name__ == '__main__':main()

2.命令行

root@debian-ai:~/json2redis_test# python3 ./gpjson2redis.py
usage: gpjson2redis.py [-h] [--redis_ip REDIS_IP] [--redis_port REDIS_PORT] [--verbose] jsonfile
