QQ音乐爬虫（odeJs）

QQ音乐爬虫（odeJs）

一、创建一个文件夹

　　例如我创建在D:\code\qq-music

　　在文件目录打开cmd

　　在cmd中执行 npm init 项目初始化

　　然后安装一些工具包： 

　　npm i request -s

　　npm i querystring -s

　　在目录下创建一个Music的文件夹用于存储下载的音乐文件

二、直接上代码　　D:\code\qq-music\qqMusic.js

ct request = require(	request	);
ct fs = require(	fs	); //文件模块
ct querystring=require(querystring);

ct downMusic = function(UrlJsonObj){
    ct baseUrl = http://124.22.155.157/qq/;
    for(var attr in UrlJsonObj){
        ct musicJsonObj = UrlJsonObj[attr];
        ct songname = musicJsonObj.songname;
        ct songUrl = musicJsonObj.songUrl;
        request(baseUrlsongUrl).pipe((	./Music/	songname	.m4a	))
    }
};

ct makeMusicJsonArray = function(songJsonArray){
    ct baseUrl = .fcg;
    let UrlJsonObj = {};
    (function(musicInfo){
        ct songname = musicInfo.songname;
        ct songmid = musicInfo.songmid;
        ct url = baseUrl?querystring.stringify(musicInfo.params);
        request(url, function (error, respe, body) {
            ct BodyJson = JSO.parse(body);
            let musicInfo = {
                songname : this.songname
            };
            musicInfo[songUrl] = BodyJson[req_0][data][midurlinfo][0][purl];
            UrlJsonObj[this.songmid] = musicInfo;
            if(Object.getOwnPropertyames(UrlJsonObj).length == songJsonArray.length){
                this.downMusic(UrlJsonObj)
            }
        }.bind({
            songname : songname,
            songmid : songmid,
            downMusic : downMusic
        }));
    });
};

下面标红的是我在这个页面到的歌曲清单接口

ct queryMusicList = function(){
    request(	.fcg?tpl=&page=detail&date=2018_41&topid=26&type=top&song_begin=0&song_num=00&g_tk=581&loginUin=0&hostUin=0&format=jsonp&inCharset=utf8&outCharset=utf-8&notice=0&platform=yqq&needewCode=0	, function (error, respe, body) {
        if(respe.statusCode == 200){
            body = JSO.parse(body);
            ct songList = body.songlist;
            let songJsonArray = [];
            (function(songDetail){
                songDetail = songDetail.data;
                ct songJsonObj = {
                    	albumname	 : songDetail.albumname,
                    	albummid	 : songDetail.albummid,
                    	singer	:  songDetail.singer[0][name],
                    	songname	: songDetail.songname,
                    	songmid	: songDetail.songmid,
                    	songtype	: songDetail.songtype
                };

                ct musicParams  = {
                    req:{
                        module:CD.SrfCdnDispatchServer,
                        method:GetCdnDispatch,
                        param:{
                            guid:1111,
                            calltype:0,
                            userip:
                        }
                    },
                    req_0:{
                        module:vkey.GetVkeyServer,
                        method:CgiGetVkey,
                        param:{
                            guid:1111,
                            songmid:[songDetail.songmid],
                            songtype:[songDetail.songtype],
                            uin:0,
                            loginflag:1,
                            platform:20
                        }
                    },
                    comm:{
                        uin:0,
                        format:json,
                        ct:20,
                        cv:0
                    }
                };
                var params = {
                    loginUin : 0,
                    hostUin : 0,
                    format : 	jsonp	,
                    inCharset: 	utf8	,
                    outCharset: 	utf-8	,
                    notice: 0,
                    platform: 	yqq	,
                    needewCode: 0,
                    data: encodeURI(JSO.stringify(musicParams))
                };
                songJsonObj[params] = params
                songJsonArray.push(songJsonObj)
            });
            makeMusicJsonArray(songJsonArray);

        }
    });
};

queryMusicList();

三、运行代码
node qqMusic.js
