进入酷我音乐的网站到搜索界面

输入歌名进去打开开发者工具会发现这个包

它里面包含了这一页的音乐数据，我们需要的是这个参数

然后开始写代码吧，先找到所需的音乐数据

接下来是重要的地方

先随便试听一首音乐，找到他的json数据

我们发现这个json数据里含有.mp3的链接，这就是音乐文件

复制他的url，进去看是一个接口

他的url有规律，之前我们提取的rid参数就起了作用，把它复制到链接里，这里看代码吧

<code class="prism language-python has-numbering"><span class="token comment"># 遍历拿到所需要的数据，音乐名称，歌手，id...
<span class="token keyword">for i <span class="token keyword">in datapack<span class="token punctuation">:
    <span class="token comment"># 音乐名
    music_name <span class="token operator">= i<span class="token punctuation">[<span class="token string">"name"<span class="token punctuation">]

    music_singer <span class="token operator">= i<span class="token punctuation">[<span class="token string">"artist"<span class="token punctuation">]
    <span class="token comment"># 待会需要的id先拿到
    rid <span class="token operator">= i<span class="token punctuation">[<span class="token string">"rid"<span class="token punctuation">]

顺便写了个方便下载的功能

<code class="prism language-python has-numbering"> <span class="token comment"># 在此之前先创建列表
 music_list <span class="token operator">= <span class="token punctuation">[<span class="token punctuation">]

遍历之前的列表数据进行判断，利用索引找到指定的url
