利用 Python 爬虫技术破解网易云音乐 JS 接口，快速获取歌曲数据

随着技术的不断发展，越来越多的开发者开始探索如何利用 Python、JavaScript 和爬虫技术获取互联网上的有价值数据。今天，我将带你走进一个有趣的技术领域——通过逆向网易云音乐的 JS 接口，快速获取歌曲数据。这不仅有助于加深你对爬虫技术的理解，还能帮助你更好地掌握 JavaScript 加密算法与请求构造的技巧。

背景

网易云音乐是国内最大的音乐平台之一，拥有丰富的音乐资源。在爬虫的应用中，如何从网站中提取数据是核心问题之一。尤其是在面对加密接口时，如何分析和破解这些加密机制往往是技术的难点。

今天，我们将通过 Python 和 JavaScript 的结合，实现爬取网易云音乐歌曲信息的功能。通过逆向网易云音乐的 JS 接口，我们可以轻松破解加密机制，获取到歌曲的详细信息。

关键步骤解析：

首先，我们需要准备一些基本的请求头和 Cookie，以便模拟浏览器的请求。下面是我们需要用到的 headers 和 cookies 配置：

import requests
import execjs

headers = {
    "accept": "*/*",
    "accept-language": "zh-CN,zh;q=0.9",
    "cache-control": "no-cache",
