Base64转存文件

def save_base64_image(base64_string, output_dir, filename):
    # 确保输出目录存在
    if not os.path.exists(output_dir):
        os.makedirs(output_dir)
    # 解码Base64字符串
    image_data = base64.b64decode(base64_string)
    # 将解码的图像数据转换为PIL Image对象
    image = Image.open(BytesIO(image_data))
    # 构建完整的输出路径
    output_path = os.path.join(output_dir, filename)
    # 保存图像到指定路径
    image.save(output_path)
    logging.info(f"Image saved to {output_path}")
    return f"{output_path}/{filename}"

output_path = "./images"
filename = "test.jpg"
file_path = save_base64_image("xxxxx",output_path,filename)

使用logging打印日志

import logging

logging.basicConfig(level=logging.INFO)

logging.error(f"Kafka error: {msg.error()}")
logging.info(f"Processing message: {msgJson}")

使用JSON存储配置，并读取

import json
CONFIG_FILE = 'config.json'
with open(CONFIG_FILE) as config_file:
    config = json.load(config_file)

mqtt_broker = config['mqtt_broker']

{
    "mqtt_broker": "192.168.1.5"
}

任务队列
