通过客户端js或.m3u8文件扩展名下载VKontakte音频

这一切是如何开始的...


和往常一样，我决定挂在VKontakte上，将一些新的录音下载到计算机上。 但是我很失望：录音以某种奇怪的格式返回：m3u8。 这种格式甚至没有播放vlc媒体播放器，我开始考虑该怎么做...

实际做什么？


谷歌搜索它是哪种.m3u8格式，我意识到这是.m3u格式的音频。 好的，下载此.m3u8文件，使用文本编辑器将其打开，然后看到类似以下内容的内容：

-录音路径。 也就是说，您需要为每个路径替换一个主机，并且很可能该音频将变为可播放。 在python上快速抛出了几行代码后，我们实现了这一点：

我们得到了一个已经可以播放的.m3u文件。

但是！ 问题是：

  • 仅在指向音频间隙的链接有效时才能播放此文件。
  • 您还可以仅在链接有效的情况下转换文件
  • 您只能在接收文件的计算机上转换文件。 链接绑定到PC的IP地址。

了解了所有这些之后，我决定在客户端js上编写一个程序，以便可以在命令行上执行它。 这是我得到的：

程序
 class music_get{ constructor(){ this.el=document.getElementsByClassName("audio_row"); this.str_param=[]; this.json=[]; this.last_len=this.el.length; this.make_str(this.el); this.load_audio_to_json(0,this.str_param[0]); } parse(element_){ //,  id ,     ,   . //let i=JSON.parse(element_.attributes['data-audio'].nodeValue),s1=i[13].split("/"); //return i[1]+"_"+i[0]+"_"+s1[2]+"_"+s1[s1.length-2]; let i = AudioUtils.asObject(JSON.parse(element_.getAttribute('data-audio'))); return i.fullId+"_"+i.actionHash+"_"+i.urlHash; } encode_url(t) { //,     let c = {v:(t)=> { return t.split('').reverse().join('')},r: (t, e) => {t = t.split('');for (let i, o = _ + _, a = t.length; a--; ) ~(i = o.indexOf(t[a])) && (t[a] = o.substr(i - e, 1));return t.join('')}, s: (t,e)=> { let i = t.length;if (i) { let o = function(t, e) {let i = t.length,o = [];if (i) {let a = i;for (e = Math.abs(e); a--; ) e = (i * (a + 1) ^ e + a) % i,o[a] = e }return o}(t, e), a = 0;for (t = t.split(''); ++a < i; ) t[a] = t.splice(o[i - 1 - a], 1, t[a]) [0];t = t.join('')}return t}, i:(t, e)=> {return cs(t, e ^ vk.id)},x: (t, e)=> {let i = [];return e = e.charCodeAt(0),each(t.split(''), (t, o) => {i.push(String.fromCharCode(o.charCodeAt(0) ^ e))}),i.join('')} },_ = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMN0PQRSTUVWXYZO123456789+/=',h=(t)=>{ if (!t || t.length % 4 == 1) return !1;for (var e, i, o = 0, a = 0, s = ''; i = t.charAt(a++); ) ~(i = _.indexOf(i)) && (e = o % 4 ? 64 * e + i : i, o++ % 4) && (s += String.fromCharCode(255 & e >> ( - 2 * o & 6)));return s}; if ((!window.wbopen || !~(window.open + '').indexOf('wbopen')) && ~t.indexOf('audio_api_unavailable')) { let e = t.split('?extra=')[1].split('#'),i=''===e[1]?'':h(e[1]); if (e = h(e[0]), 'string' != typeof i || !e) return t;for (var o, a, s = (i = i ? i.split(String.fromCharCode(9)) : []).length; s--; ) {if (o = (a = i[s].split(String.fromCharCode(11))).splice(0, 1, e) [0], !c[o]) return t; e = c[o].apply(null, a)}if (e && 'http' === e.substr(0, 4)) return e}return t } end(){ //    html    each(this.json,(_,item)=>{ let els = document.querySelectorAll('[data-full-id="'+item.fullId+'"]')[0]; if(els.children[0].children[6].children.length===3)return; els.children[0].children[6].innerHTML+="<div onclick='new music_download().download(this);' style='float:right;height:40px;width:40px;background:url(/doc472427950_504561254) no-repeat 5px 5px;'></div>" els.children[0].children[6].children[2].attributes.info=item; }); } make_str(mass){ //,    str_param   id ,     . each(mass,(i,e)=>{ if(Math.floor(i/10)===i/10) this.str_param.push(this.parse(e)); else this.str_param[this.str_param.length-1]+=","+this.parse(e); }); } load_audio_to_json(i,l){ //    ,        , //       this.json ajax.post("/al_audio.php",{act:'reload_audio',al:'1',ids:l},{onDone:(a)=>{ //each - ,     vk.com -   array.forEach each(a,(_,c)=>{ c=AudioUtils.asObject(c); //   ,    ) c.url = this.encode_url(c.url); this.json.push(c); }); // if(this.str_param.length-1===i) this.end(); else this.load_audio_to_json(i+1,this.str_param[i+1]); }}); } _update_scroll(){ //,    . if(this.el.length===this.last_len)return; let c = this.el.length,offset=c-this.last_len; this.last_len=c; let arr = Array.from(this.el).splice(-offset); this._load_button(arr); } _load_button(list){ //,    . let leng=this.str_param.length-1; this.make_str(list); this.load_audio_to_json(leng,this.str_param[leng]); } } class music_download{ //constructor(){} download(e){ this.info = e.attributes.info; //   - .mp3,        if(this.info.url.indexOf(".mp3?")!==-1) window.open(this.info.url); else //       .m3u8,   (), //       .ts,    . //    response: fetch(this.info.url).then((e)=>e.text().then((e)=>this.response(e))); } response(data){ let alls = data.match(/\n.+?\.ts\?/ig), host=this.info.url.split("index.m3u8")[0]; each(alls,(_,e)=>data=data.replace(e,"\n"+host+e.replace('\n',''))); //   this.download_data(this.info.title.replace(/[-\/\\:*?"<>|]/gim,'')+".m3u8",data); } download_data(f_n, t) { let e = document.createElement('a'); e.setAttribute('href', //'data:text/plain;charset=utf-8,' 'data:text/html;base64,'+ btoa(t)); e.setAttribute('download', f_n); e.style.display = 'none'; document.body.appendChild(e); e.click(); document.body.removeChild(e); } } var mus = new music_get(); //  window.onscroll=()=>mus._update_scroll();

结果是这样的：


此外，将所有音频下载到一个文件夹中后，我编写了以下python代码，将所有.m3u8音频转换为.ts ：

代号
 import requests,re,os def convert_mp3(f): z=open(f).read() con=list(map(lambda e: e.rstrip('\n').rstrip('#EXT-X-ENDLIST').rstrip("\n") if '#EXTM3U' not in e else '' ,re.split('#EXTINF:\d+.\d+,\n',z))) z = b'' for r in con: if(r==''):continue; z+=requests.get(r).content open(f.strip(".m3u8")+".ts",'bw').write(z) z=set() for file in os.listdir(): if file.endswith(".m3u8"): z.add(file) convert_mp3(file) z=',\n'.join(z) input(f":{z} .\n Enter,  !")


原则上，您可以尝试在js上合并.ts摘录，然后下载整个文件，但我没有成功（

PS成功的人-在评论中写下
PPS我忘了说Yandex.browser仍然会返回指向.mp3的链接）

更新：


如正确指出的nokimaro，您可以立即下载mp3：
