某网站音频下载

是要下载2楼说的网站里的1800+音频
http://www.yuetingba.cn/book/detail/3a0a4394-004b-58cc-bee6-fd01e7787da4/0


我试着分析了一下
页面是

onclick=

testFn('3a0a487b-f73b-aae9-f268-d501098118b9')

只能通过浏览器的开发者工具直接得到真实的mp3地址
1800我多个文件，总不能一个一个下载吧
哪位大神帮分析一下，通过

testFn('3a0a487b-f73b-aae9-f268-d501098118b9')如何得到真实的地址

我好写个工具把音频下载下来

抓包 http://www.yuetingba.cn/api/app/docs-listen/3a0a487b-f73b-aae9-f268-d501098118b9/ting-with-ef 请求：

{
    "id": "3a0a487b-f73b-aae9-f268-d501098118b9",
    "bookId": "3a0a4394-004b-58cc-bee6-fd01e7787da4",
    "tingNo": 1,
    "title": "",
    "ef": "Ob1B4vtdV6FAXBD3sD3PlI02ie5zefztNrbsg7VpNwRxvQfcxrTgKcUDnTF/weOy8Ut7cNwUVGLgfsY6RQuAfegb3ogVjwIwzwG5Qxaplve/S5JTVFlupQ99g2eRi8E2D5SBAhY3EIbFxVyvIEHH2Q=="
}

剩下的就很简单了，交给你自己琢磨：

let wo = new class {
    constructor() {
        this.key = mo.enc.Base64.parse("le95G3hnFDJsBE+1/v9eYw=="),
        this.iv = mo.enc.Base64.parse("IvswQFEUdKYf+d1wKpYLTg==")
    }
    encrypt(e) {
        const t = mo.enc.Utf8.parse(e);
        return mo.AES.encrypt(t, this.key, {
            iv: this.iv,
            mode: mo.mode.CBC,
            padding: mo.pad.Pkcs7
        }).ciphertext.toString(mo.enc.Base64)
    }
    decrypt(e) {
        e = (e + "").replace(/\n*$/g, "").replace(/\n/g, "");
        const t = mo.enc.Base64.parse(e)
          , n = mo.enc.Base64.stringify(t);
        return mo.AES.decrypt(n, this.key, {
            iv: this.iv,
            mode: mo.mode.CBC,
            padding: mo.pad.Pkcs7
        }).toString(mo.enc.Utf8).toString()
    }
}

是啊，通过浏览器自带的开发者工具也能得到这个IP
一个一个的下载，太麻烦

利用猫爪嗅探的话，还要外挂下载器，期待楼主搞个一步到位
