动态创建json文件，并在python中追加日志内容

import json

log_data = {
    "timestamp": "2022-01-01 12:00:00",
    "message": "This is a log message"
}

file_path = "logs.json"

try:
    with open(file_path, "r") as file:
        # 读取现有的JSON数据
        json_data = json.load(file)
except FileNotFoundError:
    # 如果文件不存在，则创建一个空的JSON对象
    json_data = {}

# 将日志内容追加到JSON对象中
json_data["logs"] = json_data.get("logs", []) + [log_data]

# 将更新后的JSON数据写入文件
with open(file_path, "w") as file:
    json.dump(json_data, file, indent=4)
