Qt 网易云api 在线播放音乐

之前用了一个私人的api，没用到1个月就没了，实在烦恼~无意间通过wireshark抓到网易云音乐，然后解析了一下就Okay。解包里有mp3url，就okay了。然后通过加载就okay。

至于歌词部分是被加密了的。。实在找不到方法解密。就又调用了一个酷狗音乐的歌词api。

一.请求搜索歌曲：

QNetworkAccessManager*manger=newQNetworkAccessManager;

QNetworkRequest *request=new QNetworkRequest;

request->setUrl(QUrl(http://music.163.com/api/search/pc));

request->setRawHeader("Cookie","os=pc");

request->setRawHeader("Host","music.163.com");

request->setRawHeader("MUSIC_U","5339640232");

request->setRawHeader("Referer",http://music.163.com/);

manger->post(*request,"offset=0&total=true&limit=100&type=1&s="+byt);

connect(manger,SIGNAL(finished(QNetworkReply*)),this,SLOT(workfinished(QNetworkReply*)));

二.处理返回内容：
QJsonDocument doc=QJsonDocument::fromJson(byt);

QJsonObject obj0=doc.object();

QJsonObject obj1=obj0.value("result").toObject();

QJsonArray arry=obj1.value("songs").toArray();

int arrycount=arry.count();

for(int i=0;i<arrycount;i++)

{

QJsonObject obj2=arry.at(i).toObject();

QString songname=obj2.value("name").toString();//获取音乐名字

QJsonArray arry1=obj2.value("artists").toArray();

QJsonObject obj3=arry1.at(0).toObject();

QString author= obj3.value("name").toString();//获取歌手名字

connect(addnetplaybtn,SIGNAL(clicked()),this,SLOT(addplaynetListslot()));

connect(downbtn,SIGNAL(clicked()),this,SLOT(downloadnetsong()));

}
