使用Python与腾讯云接口对接，实现人流统计功能

import requests

# 腾讯云人流统计接口地址
url = "https://api.youtu.qq.com/vision/v2/traffic/flow"

# 填写你在腾讯云申请到的AppID、SecretId和SecretKey
app_id = "your_app_id"
secret_id = "your_secret_id"
secret_key = "your_secret_key"

# 请求参数
params = {
    "url": "http://example.com/video.mp4",  # 视频流地址
    "appid": app_id,
    "secretid": secret_id,
    "secretkey": secret_key,
}

# 发送POST请求
response = requests.post(url, params)

# 解析返回结果
if response.status_code == 200:
    result = response.json()
    if result["ret"] == 0:
        print("人流统计结果：")
        print("总人数：", result["flow"]["total_count"])
        print("男性人数：", result["flow"]["male_count"])
        print("女性人数：", result["flow"]["female_count"])
        print("年龄分布：")
        for age in result["flow"]["age"]:
            print("年龄段：", age["age"], "人数：", age["count"])
    else:
        print("人流统计失败：", result["msg"])
else:
    print("请求错误：", response.status_code)
