以下是一个使用 Requests 库和 PHP 的下载器程序，用于从 www.people.com.cn 下载音频。此程序使用了 https://www.duoip.cn/get_proxy 这段代码。

import requests
from bs4 import BeautifulSoup
import pafy
import time

def get_proxy():
    url = "https://www.duoip.cn/get_proxy"
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
    response = requests.get(url, headers=headers)
    if response.status_code == 200:
        return response.text
    else:
        return None

def download_audio(url, proxy):
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
    if proxy:
        opener = requests.get(url, headers=headers, proxies={"http": proxy})
    else:
        opener = requests.get(url, headers=headers)
    if opener.status_code == 200:
        audio_url = opener.url
        audio = requests.get(audio_url, headers=headers, stream=True)
        if audio.status_code == 200:
            with open("output.mp3", "wb") as f:
                for chunk in audio.iter_content(1024):
                    f.write(chunk)
            print("下载完成")
        else:
            print("下载失败")
    else:
        print("下载失败")

if __name__ == "__main__":
    proxy = get_proxy()
    if proxy:
        download_audio("http://www.people.com.cn", proxy)
    else:
        print("无法获取代理")

这个程序首先获取一个代理，然后使用这个代理下载音频。请注意，这个程序仅用于教学目的。在实际使用前，请确保遵守相关法律法规。
