Python Script for Vehicle Violation Record Query Using Alibaba Cloud API

With the rapid development of the Internet, convenient queries such as vehicle violation record checks have become popular; this tutorial shows how to implement a vehicle violation query function using Python.

The data is accessed via the Alibaba Cloud API Marketplace, specifically the Tianyan data service, which provides a free test package allowing up to ten test requests.

After logging into Alibaba Cloud, select the free test package, purchase it, and obtain the AppCode needed for authentication.

Below is the complete Python implementation. import requests Prompt the user for vehicle information:

car_no = input("请输入如车牌号：")
car_type = input("请输入如车辆类型，大车输入01，小车输入02：")
engine_number = input("请输入如车辆引擎号：")
frame_number = input("请输入如车架号：")

Define the main function that builds the request and processes the response:

def main():
    """主函数"""
    # 请求网址
    url = "http://carwz.shumaidata.com/post/carwz"
    # 接口 appcode
    appcode = 'fd1dfdc3c97447f6b5259ebaf51808f7'
    # headers 信息
    headers = {'Authorization': f'APPCODE {appcode}'}
    # 请求数据
    data = {
        'car_no': car_no,
        'car_type': car_type,
        'engine_number': engine_number,
        'frame_number': frame_number
    }
    try:
        # 发送 post 请求
        response = requests.post(url, params=data, headers=headers)
        content = response.json()
        if content["code"] != '0':
            print("请求失败, 请检查您的输入信息")
            return
        carNo = content["result"]["carNo"]
        if content["result"]["vioNum"] == "0":
            print(f"您的车牌号{carNo}没有违章记录")
        else:
            print(f"您的车牌号{carNo}有如下违章记录")
            # 遍历违章记录
            for item in content["result"]["data"]:
                print("*" * 20)
                print(f"""
违章时间: {item["vioTime"]}
违章地点: {item["vioAddress"]}
违章原因: {item["vioAction"]}
罚款金额: {item["vioFine"]}
罚款扣分: {item["vioScore"]}
""")
    except Exception:
        print("请求异常")

if __name__ == '__main__':
    main()

The script sends a POST request with the vehicle details, checks the response code, and either reports that there are no violations or iterates through the returned violation records, printing the time, location, reason, fine amount, and penalty points for each.

Example interaction shows a user entering a license plate, vehicle type, engine number, and frame number, after which the program reports that the vehicle has no violation records.
