Youtube 下载链接来自 http://www.youtube-mp3.org/ [英] Youtube download link from http://www.youtube-mp3.org/

问题描述

我一直在使用 http://www.youtube-mp3.org/为互联网广播"项目获取 mp3 歌曲的下载链接(下载文件流并输出).最近 http://www.youtube-mp3.org/ 似乎改变了它的工作流程.到目前为止，我能够获得正确格式的网址:

norel.youtube-mp3.org/get?ab=128&video_id=KMU0tzLwhbE&h=5671e7d33d4eccb5b89ea8f54d9911d4&r=1387110278658.1527580295

而 r=时间戳我自己将时间戳记为纪元.这在没有 .1527580295 后缀的情况下运行良好.不幸的是，这似乎是必需的，因为没有后缀的链接会重定向回转换站点.

到目前为止，算法如上所述:

Youtube mp3 org linq 获取说明

http://www.youtube-mp3.org/api/itemInfo/?video_id=#{video_id}&ac=www&r=#{Time.now.to_i}

有谁知道如何获取后缀部分?

//嘿，我不太喜欢网络编程……但我确实忽略了这一点.谢谢！

将此添加到我的小型 C# API 中.

 const int AM = 65521；int GetCCSufix(string a){int c = 1, b = 0, d, e;var chars = a.ToCharArray();for(e =0; e

效果很好;)

解决方案

我不知道这个后缀是什么意思，但是从 youtube-mp3.org 阅读客户端 javascript 文件，您可以了解如何生成它.

var __AM=65521;//小于 2^16 的最大素数...函数 cc(a){var c = 1, b = 0, d, e;for(e = 0; e < a.length; e++){d = a.charCodeAt(e);c = (c+d)%__AM;b = (b+c)%__AM;}返回 b<<16|c;}

生成的媒体 URL 是:

"http://www.youtube-mp3.org/get?ab=128&video_id="+video_id+"&h="+info.h+"&r="+timeNow+"."+cc(video_id+timeNow)

与

var timeNow = Date.now().toString();

I've been using the http://www.youtube-mp3.org/ to obtain download links for mp3 songs for a "internet radio" project (download file stream and output it). Lately the http://www.youtube-mp3.org/ seemed to changed it's workflow. Till now I was able to obtain the proper format of the url:

http://www.youtube-mp3.org/get?ab=128&video_id=KMU0tzLwhbE&h=5671e7d33d4eccb5b89ea8f54d9911d4&r=1387110278658.1527580295

Whereas r=timestamp I did the timestamp myself as epoch. This worked well without the .1527580295 suffix. Unfortunetly this seems to be needed as the link without the suffix redirects back to the conversion site.

Up till now the algorithim was as mentioned:

http://www.youtube-mp3.org/api/itemInfo/?video_id=#{video_id}&ac=www&r=#{Time.now.to_i}

Does any one know how to obtain the suffix part?

//Hey, I'm not much of an web programming guy ... but this is something I have surely overlooked. Thanks!

Added this to my small C# API.

  <!-- language: c# -->
    const int AM = 65521;
    int GetCCSufix(string a)
    {            
        int c = 1, b = 0, d, e;
        var chars = a.ToCharArray();
        for(e =0; e< chars.Length; e ++)
        {
            d = chars[e];
            c = (c + d) % AM;
            b = (b + c) % AM;
        }
        return b << 16 | c;
    }

Works great ;)

解决方案

I don't know what this suffix means but reading the client javascript file from youtube-mp3.org you can learn how to generate it.

var __AM=65521; // the largest prime less than 2^16...
function cc(a){
    var c = 1, b = 0, d, e;
    for(e = 0; e < a.length; e++){
        d = a.charCodeAt(e);
        c = (c+d)%__AM;
        b = (b+c)%__AM;
    }
    return b<<16|c;
}

The generated media URL is :

"http://www.youtube-mp3.org/get?ab=128&video_id="+video_id+"&h="+info.h+"&r="+timeNow+"."+cc(video_id+timeNow)

with

var timeNow = Date.now().toString();
