import json
from qcloud_cos import CosConfig
from qcloud_cos import CosS3Client

# 解析json对象
json_str = '{"name": "John", "age": 30, "city": "New York"}'
data = json.loads(json_str)

# 更新json元素
data['age'] = 31

# 将修改后的数据转换为json格式
updated_json_str = json.dumps(data)

# 保存到腾讯云COS对象存储服务

client = CosS3Client(config)
response = client.put_object(
    Bucket=bucket,
    Key=key,
    Body=updated_json_str.encode('utf-8')
)

print("Json元素更新成功！")
