Youtube下载链接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/ 获取互联网广播项目（下载文件流并输出）的mp3歌曲的下载链接。最近， http://www.youtube-mp3.org/ 似乎改变了它的工作流程。到目前为止，我可以获得URL的正确格式：

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

而r = timestamp
我自己做了时间戳作为纪元。如果没有.1527580295后缀，这个效果很好。
不幸的是，这似乎是需要链接没有后缀重定向到转换站点。

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.

到目前为止，算法如下所述：

Up till now the algorithim was as mentioned:

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}

有没有人知道如何获得后缀部分？

Does any one know how to obtain the suffix part?

//嘿，
我不是一个网络编程人，但这是我一直被忽视的东西。谢谢！

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

将其添加到我的小C＃API。

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;
    }

工作很棒;）

推荐答案

我不知道这个后缀是什么意思，但是从youtube-mp3.org读取客户端javascript文件，您可以学习如何生成它。

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;
}

生成的媒体网址是：

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

with

with

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